Dear Readers
While I write this editorial there is just a little over three months left of 2009, a year
that brought a dramatic shift in the economy for many. Some see 2009 as a lost year,
whereas others may consider it acceptable under the circumstances. On a positive
note I have been hearing that the economic situation has been showing a slight
improvement during September with business starting to pick up.
Here in Europe I feel that that is the general opinion, but recently the finance
ministers from all the European Union member countries gathered in Gothenburg for
an unofficial session to discuss the economic situation within the EU. The result of
this meeting was that all ministers agreed that the financial crises has hit the economy
harder then expected and the speed of economic growth within EU will drop around
50% compared to 2008. This is certainly not good news for the European economy.
Countries that depend on their exports from Europe will face dropping sales from
the European markets. Regions and countries with more diversified exports, such as
the USA, South America and China will suffer less while waiting for the European
market to recover.
I believe that no one can answer the question of how long it will take until Europe’s
economy will change for the better. Several countries have very low interest rates in
order to help the situation. But as the interest rate is controlled by the Central Bank
of each country, it might be necessary to increase the interest rates if the governments
need to introduce special measures to help the economy. What the ministers agreed at
the meeting in Gothenburg is that regions like China, Latin America and also USA
will play a more important role for the European economy in the near future.
Measures to improve the situation in Europe are aimed at making people work
longer than normal retirement age. More productivity from more people will certainly
help the situation. All member countries in the EU are now trying to find ways to
implement possibilities to work longer. There are several other stimulus measures
that are being affected and preliminary this special focus on improving the economy
within the EU will continue up to 2011.
Well, not good news. For our industry I don’t believe there is any real news, but
perhaps we need to wait a bit longer for a change then we expected. For European
manufacturers with high export levels it is perhaps important to pay more attention
to markets outside Europe. But our sectors, demolition, recycling, concrete cutting,
floor grinding and polishing is very machinery and tool consuming. Our contractors
have a need to continuously renew their fleets to stay competitive. The investment
level in our industries has been tremendously low during the last twelve months,
which may be an indicator for stronger growth in the following twelve months. In
this perspective exhibitions like Bauma have a big part to play and can temporarily
boost the economy. But in the long run there needs to be conditions for a healthy
economy to thrive, and for Europe it was these conditions that were discussed at the
meeting in Gothenburg.
There has been very little in the way of product news during the year and talk-
ing to manufacturers around the world I
have concluded that we are going to see
a lot of new products in 2010. Hopefully
many of these products will be released at
the World of Concrete show in Las Vegas
and the Bauma exhibition in Munich
next year.

Words from the PresidentEU growth rate down by 50%?
Jan HermanssonEditor-in-Chief
turing towns in Britain after the second world
war and continued through the 90’s, where
we had a variety of manufacturers in the
town such as 4 different car plants, we also
manufactured cycles, motor cycles, planes,
farm tractors, forklift trucks, tanks and field
guns to the world’s largest machine tool
manufacturers. We had large foundries,
pressed tool manufacturers and many
supporting engineering factories. With all
these industries there was a lot of work to be
had and plenty of employment for the local
residents. But they have all closed down
and Coventry is now not a manufacturing
town in any shape or form.
Although with the loss of industry a lot
of drilling and sawing work takes place and
I often wonder where the business comes
from. Perhaps I should have carried out
a survey in my own company to find out
where the new business had come from.
I strongly feel that both government and
banks have not supported industry in the
Western World so much that manufacturing
has disappeared from most of the European
and Western World countries.
I hope that all members of Drilling and
Sawing and Demolition associations support
their manufacturing members so that devel-
opment of new innovations for equipment
and techniques may continue.
There is talk of green shoots the first
signs of the recession lifting and I do
hope that this is the case for the sake of
all of us and wishing everyone a good
coming year.

“Survival of the fittest”Martin Jennings said in a recent article
for the Industrial Diamond Quarterly issue
1/09: “2009 sees the 200th anniversary
of the birth of Charles Darwin – somewhat
appropriate in these difficult times were
“survival of the fittest”, will most certainly
describe those companies that manage to
work their way through the recession and be
in a position to pick up the reins once global
conditions start to improve”.
On a side note I play golf at a famous
Welsh golf lynx course that has been voted
the 70th best golf club in England, Scotland,
Wales and Ireland. Our first captain in 1896
was Charles Darwin’s grandson, Bernard
Darwin. His uncle started the course, Colonel
Ruck, when he borrowed 9 flower pots from
a lady in the village and cut nine holes in the
march to place them in. Bernard Darwin went
on to become a famous golfer, playing for
England and a famous writer for the Times,
reporting on Golf as his main sport. He also
became president of our Golf club until his
death in 1961.
Anyone who wishes to play the course
please contact me at peterwhite@d-drill.
co.uk and I will be glad to entertain you there
as I am a past captain of 2007. Here is the
course website if you would like to look it
up www.aberdoveygolf.co.uk.
To get back to Drilling and Sawing with a
world wide down turn of work most compa-
nies have had to down size their businesses
and will have had to, to survive. Most of the
big world manufacturers have decreased
their manufacturing capacity.
Over the last 44 years that I have been
in the business I have seen tremendous
development in equipment and technology
in the demolition, diamond drilling and
sawing industries and I do hope that the
expansion of these technologies do
not cease due to the lack of funding
for these projects. We need the most
advanced equipment to be able to tackle
the larger and complicated contracts that
are being undertaken today.
I do wonder where a
lot of drilling and saw-
ing business is going to
come from in the future.
For instance take the
town I live in, Coventry,
England it was one of
the biggest manufac-

Words from O’Brien
Silica - Wet versus Dry SawingIn 2004, the U.S. Occupational Safety and
Health Administration (OSHA) proposed new
regulations for exposure to respirable silica in
the construction industry. A reduction of the
Permissible Exposure Limit (PEL) level from 1.0
to 0.25 was proposed, but many felt that this
proposal showed a lack of understanding on
the part of regulators concerning the impact this
standard would have on small businesses.
The proposed standard would have re-
quired construction companies to initiate many
new procedures. For example, an industrial
hygienist hired by the contractor would be
required to provide sampling services on each
and every site. The contractor would also have
to designate a “competent person” to identify
and evaluate silica exposure hazards, establish
a perimeter and constantly monitor the qual-
ity of the air. The contractor would have to
make respirators and Tyvek clothing available
to workers as well as anyone entering the
job site including trades working in adjacent
areas. Medical screening and exam costs for
employees would skyrocket. Record-keeping
costs to comply would drive administrative
expenses up.
The proposed new regulations were never
enacted by OSHA and it may have been due
to feedback they received from the OSHA
Small Business Advocacy Review (SBAR)
Panel or other feedback they received. The
panel presented documentation that showed
the estimated cost to a small business of
$12,000 would have actually been close to
$3 million and put many small businesses
out of work. CSDA was active in working with
other associations to propose an alternative
“control banding” approach. Under this pro-
posal, operators would arrive on the job, and
based upon the type of sawing or drilling to be
performed and whether it would be inside or
outside, they would have a simple chart to let
them know what type of filter or mask would
be required, if any.
Since that time, CSDA has continued to
collect airborne silica data on the different
cutting operations. We invited the National
Institute of Occupational Safety and Health
(NIOSH) to our training sessions to examine
the silica exposure for operators. Based upon
the fact that a typical CSDA cutting contractor
performs cutting operations wet over 95%
of the time the exposure dangers are greatly
minimized as confirmed by NIOSH. Cutting pros
have traditionally cut wet to extend the blade or
bit life of the diamond tool, but the secondary
benefit is to almost eliminate operator exposure
to respiratory silica.
However, those contractors who have
traditionally cut dry face a different challenge.
Manufacturers have been active in developing
dust collection systems to control and minimize
the exposure to crystalline silica. So whether
the contractor is cutting wet or dry, it would
appear that industry is proactively responding
to this threat to operator health even in the
absence of new government regulations. This
speaks very highly of the industry, both manu-
facturers and contractors, and is a testament
to their commitment to providing a safe work
environment for their operators.

Sweden has been and still is a breeding ground for many different methods and products related to the building and construction sector. Hydrodemolition and remotely controlled demolition robot techniques, as well as the modern methods of grinding and polishing concrete floors were developed in Sweden. The country harbours some of the world’s biggest manufacturers of demolition attachments, concrete cutting, floor grinding, dust extraction and crushing equipment.
Early with targeted media and shows
As a result of the great interest for these sectors Sweden was also one of the first countries to publish specialist magazines and stage shows for the demolition sectors. The first professional branch magazines covering these areas were founded in Sweden in the early 1990s. In 1998 the first international show focused on demolition, recycling, concrete sawing and drilling and floor grinding equipment was held at the InfraCity Business Centre north of Stockholm. Two years later Professional Demolition In-ternational magazine (PDi) was founded. The demolition show at InfraCity was an immediate success and attracted manufacturers and contractors. The demolition show was also held in 2000 at InfraCity and afterwards passed to new ownership. The show’s original owner and organiser S.C.O.P. AB was, for several years, unable to organise competitive shows due to a competition clause in the change of ownership agreement.
Everything set for DEMCON 2010
However, the agreement has now lapsed and. S.C.O.P. AB is now launching a new show in the same spirit as its forerunner. The show and its location is the same, but the name is new, DEM-CON. The show will take place at the business and exhibition centre InfraCity, located in the Stockholm suburb of Bredden between the city centre and Arlanda International Airport. The DEMCON show will take place on 9-10 September 2010 and will focus on demolition, concrete sawing and drilling, concrete floor preparation and polishing, clean air and recycling.
“What we mainly do is produce construction related maga-
zines, including the magazine PDi. We organised the show in 1998 and 2000 and it was an instant suc- cess. Many in the demolition, recycling and concrete saw-ing industries have since asked when we are going to organise a similar show again. So in response to industry demand we w i l l be back in 2010 with the new show DEMCON and I am really looking forward to it,” says S.C.O.P. AB President Jan Hermans-son.
This is a time where the whole world has be-come the market for many suppliers to the demolition, concrete cutting and recycling industries. That is why DEMCON is aiming to become an international show, just as much as a regional one for the northern markets of Europe.
DEMCON aims to attract manufacturers and contractors from the following sectors:
All forms of demolition and demolition equipment, such as remotely controlled demolition robots, excavators designed for demolition purposes using long reach demolition booms, booms for heavy duty demolition, implosion techniques and equipment, special disman-tling equipment like wire saws for complex demolition tasks and hydrodemolition equipment.
Various attachments and tools for demolition, recycling, sorting, handling and crushing, like hydraulic breakers, crushers, pulveris-ers, sorting grabs, milling heads, crushing buckets and steel shears.
Concrete sawing and drilling equipment for drilling, wall sawing, wire sawing, chain and plunge sawing and power cutting.
Diamond tools for professional concrete sawing and drilling, scarify-ing, milling, grinding and polishing.
New technologies and methods behind demolition, concrete cutting, recycling and concrete floor preparation, grinding and polishing.
Professional equipment for taking care of dust and slurry on the worksite both indoors and outdoors as well as cleaning the air.
Machines and equipment for recycling different types of demolition waste using mobile recy-cling crushers, mobile screen-ers, crushing buckets, steel shears and shredders.
The show also covers all types of equipment related to the above product sectors.
Book your booth and
register at www.demcon.seThe exhibition hall at InfraCity has an indoor area covering 3,000m2 and 5,000m2 outside. In the outdoor area exhibitors will be able to demonstrate machines and visitors to test them. For more information about DEMCON or to book space at the show, please contact the organiser or visit the website www.demcon.se. Booking a booth can be made on-line at the website.
The demolition show at InfraCity in Stockholm is returning to the exhibition calendar. The first show in 1998 attracted professionals from the demolition, recycling, concrete cutting, grinding and polishing and related sectors. The exhibition was a great success with exhibitors and visitors and will be held again next year under the banner of DEMCON 2010. And the organisers are antici-pating it will be even better than the previ-ous shows.Below the InfraCity Business and Ex-hibition Centre with the Scandic Hotel InfraCity next door.

50% of exhibition space already bookedInformation about the show was launched in the Nordic countries during May this year and up to now a big number of manufactur-ers and distributors have made preliminary booth reservations. It is to remember that DEMCON is a very targeted exhibition focusing only on professionals. And the exhibition hall is rather small, around 3000 m2. The outdoor area though, where dem-onstrations will take place, is about 5000 m2. Up until now close to 50% if the indoor space is already reserved. And this is almost a year before the show.
The outdoor exhibition area, located right next to the indoor exhibition hall, with easy connection will be used for demonstrations of demolition carriers and attachments, mobile recycling crushers, concrete sawing an drilling systems, concrete floor grinding and polishing machines. This is a big area and will offer space for several exhibitors.
“Normally the weather in Sweden is clear and crisp, with very little rain and a rather nice outdoor temperature. If we are lucky it will remain the same next year too,” says Jan Hermansson.
for suppliers to the Swedish rental market. Several of the exhibitors at DEMCON will also
have booths at ExpoRent 2010. All visitors to the DEMCON show will pass through the ExpoRent
exhibition area on their way to DEMCON. The practical organisation of ExpoRent is taken care of by the
DEMCON management. Welcome to Sweden, DEMCON and ExpoRent in 2010.

DEMCON SupportersDEMCON 2010 is being organised by S.C.O.P. AB and sup-ported by the International Association for Concrete Sawers & Driller (IACDS), Swedish Demolition & Clearance Association and the Swedish Concrete Sawing & Drilling Association. DEM-CON also has a cooperation arrangement with the Gothenburg Building Machinery Exhibition, Byggmaskiner, organised by the Swedish Exhibition Centre in Gothenburg. Byggmaskiner and DEMCON will held on alternate years.
The plan is that both the Swedish Demolition & Clear-ance Association and the Swedish Concrete Sawing & Drilling Association will organise their autumn meetings during the DEMCON show. IACDS will not organise their annual meet-ing during DEMCON as it has been set for the Bauma show in Munich. Hopefully in the future some IACDS meetings can be held in conjunction with DEMCON.
Seminar and Gala Dinner
During the first day of the exhibition a special guest speaker will hold a seminar in the InfraCity Business Centre, only in Swedish though. The name of the guest speaker will be announced at a later stage. In the evening a special Gala Dinner will be held in the ballroom, which is situated in the Scandic Hotel InfraCity located next to the exhibitions centre.
ExpoRent 2010 - A
micro rental exhibitionAt the same time as DEMCON the Swedish
Rental Association Hyrex will hold their autumn meeting in the same premises. Hyrex is an
association with more then 100 Swedish rental companies. As a tradition during their meetings Hyrex is also organising
a micro exhibition for their suppliers. The ExpoRent 2010 show will be held in the large foyer of the InfraCity Exhibition Centre. The exhibition contains a number of 8m2 booths

In a previous issue of PDi we announced that the Swedish manufacturer Tractive AB, with its well-known product range Pentruder, has opened its own sales company for the North American market. The company was opened in May this year and is located in Tempe, Arizona. Responsible for the operations in North America is Terry Martin, previously responsible for the Pentruder range at the former distributor Diamond B Inc.
Top of the line sales and service
During August 2009 Tractive also decided to change their rep-resentation in Norway. A new company, Pentruder Norge A/S, will be formed by Finn Morten Hansen and Kenneth Høitomt and based in Askim. This means that Diajob A/S will no longer carry the main responsibility for Pentruder sales and service in Norway. Pentruder Norge A/S will offer sales and service through service partners. A service technician will be hired to provide fast and efficient service to all clients. Pentruder Norge A/S will also offer a 24-hour service, which can be reached on +47 94 83 39 20. A fully fitted spare parts storage room will be set up and there will be a range of machinery for demonstrations and loan.
There has also been a change in the UK and since the beginning of September sales and service responsibility has been taken over by Pentruder UK Ltd. In charge of the UK operation is Graham Crewe, who has long experience with concrete sawing and drilling as a contractor and in sales. Also in Sweden Tractive AB is creating a new sales and service company called Pentruder AB. In Sweden Harry Eklund has been selling the Pentruder product range since 1997. Harry has considerable experience of concrete cutting and will be involved in the new company.
Training in Sweden
During September Pentruder AB organised product training for mechanics and service people in Borlänge, Sweden, where
The International Construction and Building Machinery Show, SAIE, is taking place in Bologna, Italy, between the 28th until the 31st of October 2009.
The Italian demolition attachment manufacturer Trevi Benne S.p.A, which is one of the exhibitors at the show, is now taking the opportunity to invite their customers, equipment dealers, suppliers and friends to a wine, fruits and chocolate party, which will be held on Friday the 30th on the Booth A95 in Hall 36 starting at 17.00 hours.
Those PDi readers that will attend SAIE and also would like to join the party, can simply cut out the special ticket on the right and hand it over to the Trevi Benne staff. A simple and sympathetic way of spending some time together at the show.

Tyrolit Schleifmittelwerke Swarovski KG has re-sponded to the challenges of the global market and taken over American abrasives manufacturer Radiac Abrasives. In the face of economically difficult times, this strengthens the company’s international market position and protects the future of the Austrian abrasives manufacturer in the long term. The take-over agreement was signed in July 2009 and the price was not disclosed. The takeover strengthens the market position of the Tyrolit group in North America and safeguards the company’s heavily export-oriented operations in Austria.
Consolidation of Tyrolit The new synergies in the areas of production, purchasing, sales and customer service will open up new opportunities in the American market. Because of the considerable market size, the demand for abrasives in North America accounts for almost 25% of global abrasives demand. Ac-cording to the Tyrolit management, consolidation has been a major and lasting trend in the industry for many years. The current economic crisis further accelerates this development. Tyrolit is facing these challenges by actively participating in this concentration process. The acquisition of Radiac

CONEXPO-CON/AGG and IFPE earn “Fast-est 50” honoursCONEXPO-CON/AGG, the international con-struction industries exposition, and the co-lo-cated IFPE International Fluid Power Exposition, have been named by the industry magazine Tradeshow Week in the annual “Fastest 50” list for significant exhibition space growth of the 2008 events.
The last CONEXPO-CON/AGG and IFPE, held in 2008, broke records for exhibition space as well as attendance. The next edition of the triennial shows will be on 22-26 March in 2011at the Las Vegas Convention Center in Las Vegas, USA. Show management stresses that quality, not quantity, is the goal when planning CONEXPO-CON/AGG and IFPE. “We are always looking for how we can improve the shows to add value for visitors and exhibitors. We want them to have a quality show experi-ence, one that meets their business needs with maximum ROI for the time and money spent,” says CONEXPO-CON/AGG 2008 show director Megan Tanel.
“By nurturing partnerships, we develop an industry community at the shows, with co-located exhibits, conventions and meetings. All participants benefit from a one-stop location instead of multiple events, as well as increased networking and learning among industry peers,” adds IFPE 2008 show director Sara Mooney.
The shows are overseen by management committees of volunteer company executives, with a “run by the industry, to meet the needs of the industry” philosophy to ensure the shows continue to evolve and serve all participants.
Show management closely watches budgets to operate in the most cost-effective manner while still providing high levels of customer service. This means keeping costs low for exhibitors and visitors and offering value-added services. Examples include, for exhibitors, a package plan that bundles a
number of exhibit-related services into the space rate and, for visitors, complimentary shuttle busses between hotels and the
show site. www.conexpoconagg.

Scottish demolition contractor Alan Beattie is proving he has the Midas touch when it comes to beating the recession by buying a £50,000 JCB – and having it painted gold. Alan, who has been in business for 40 years and has the honor-ary title Lord of the Manor of Oversley, purchased the top-of-the range backhoe loader 4CX to show he is bucking the trend of the economic slump and to demonstrate his confidence in the “best of British” manufacturing. The gilt-edged finish – which replaces the traditional yellow and black livery synonymous with the world famous machine – should have cost him an extra £4,500 but local dealer Scot JCB decided to do the work for no extra charge. It took three weeks for a craftsman at the dealer’s Glasgow depot to complete the job and also inscribe the vehicle with two slogans: “The Gold Digger” and “Beattie’s The Best”. The backhoe loader is the 18th new JCB Alan has purchased since he started his business, A and J Demolition, during the late 1960s.

“Some New Minis”
16 PDi • Issue 3 - 2009 • Aug - sept
Despite a difficult market situ-ation in many countries around the world manufacturers have not slowed the pace of new developments.Some new mini excavators and compact loaders are featured on the following pages.
Bobcat’s new excavators and compact loaderBobcat has added the new E60 and E80 excavators and T110 compact tracked loader to its extensive range of equipment. The
line of Bobcat excavators has been extended with the launch of the E60, which weighs 6t in standard configuration with a ROPS cab and standard dipper stick. The digging force over the bucket is 39.9kN, and the digging force over the dipper stick is 26kN. The maximum digging depth i s 3.725m, the maximum dump height
3.94m and the maximum reach at ground level is 6m.
The larger 8.4t E80 crawler excava-tor, which is available with steel or rubber tracks, has a maximum digging depth of 4.15m, dump height of 4.72m and maximum reach is 6.965m. A long dipper stick is available as an option. The low noise and emission levels of the E80 make it suitable for operation in noise sensitive areas.
The new 2.3t Bobcat T110 compact tracked loader is only 1.2m wide and less than 2.3m long without attachment. Equipped as standard with rubber tracks it should appeal to a wide variety of users in numerous applications.
New 3t class excavators Bobcat has launched a completely new generation of 3t class mini-excavators, the 3.2t E32 conventional tail swing and the 3.5t E35 zero tail swing models. The E32 and E35 mini-excavators combine productivity with the ability to carry out
jobs with precision and fingertip control. The load sense piston pump and the closed centre valve enable fine metering of hydraulic flow for smooth, precise control of machine functions, while reducing hydraulic noise. The boom and dipper arm cylinders are cushioned to provide a smooth, end-of stroke operation. A thumb-operated boom offset control, located on the left joystick, enables improved control of the boom swing function while providing more floor space for the operator. A new feature is the auto-shift travel motor that allows automatic transition from the low to high-speed range or vice versa. Alternatively the auto-shift can be disengaged and the operator can use the switch located on the blade control lever to select the travel speed desired.
The undercarriages have sealed, maintenance free track rollers, a top roller and wide sprockets offering high resilience and a long service life. The open design and sloped surfaces of the X-frame undercarriage help prevent the build up of mud and debris.
Bobcat launches new TiltrotatorBobcat has launched a new range of Tiltrotator at-tachments for its line of excavators. The first of the new Tiltrotators is the TR05 model for use on the 5t Bobcat 435 excavator. According
to Bobcat, Tiltrotators are an important development in the market for exca-vators, which are increasingly being seen as tool carriers capable of much
more than simply digging holes. Using the Tiltrota-tor with the appropriate attachments can provide flexible and cost effective solutions for a wide range
of applications not normally undertaken with excavators. To complement the TR05 Tiltrotator, Bobcat is launching a new line of attachments specifically for use with the Til-trotator. They include two grading buckets, two standard digging buckets, trenching buckets, an asphalt cutter, a ripper attach-ment and a hydraulic stone grab.
As well as tilting attachments up to 40° to the left or the right, the TR05 Tiltrotator can rotate an attachment through 360° in both clockwise and counter clockwise directions. All Tiltrotator functions can be operated simultaneously and proportion-ately using the joysticks in the excavator cab. The mounting system
for the attachment on the Tiltrotator is the standard S40 hydraulic quick coupler. The operator is able to change between non-hydraulic attachments on the Tiltrotator by pressing two switches simultaneously in the cab, without having to leave the seat.
New Cat TH514 telehandlerThe new Cat TH514 telehandler has a load capacity of 5t, lift height of 13.7m and forward reach of 9.2m. Load-sensing, flow-sharing hydraulics allow for all three boom functions
to be operated simultaneously and proportionally. The 74.5 kW (101 hp) Cat C4.4 DITAAC mechanical control, turbo charged engine is standard and certified to Stage IIIA (Tier3) emission regulations. As standard, a limited slip differential fitted in the front axle allows the machines to work effectively in tough conditions.
A range of Cat work tools extends the versatility of the machines. A high visibility manual IT coupler comes as standard, with the option of a hydraulic quick coupler to allow work tool changes without leaving the cab.
The new cab is spacious and the single lever joystick with roller switches is easy to use. An in-cab LCD displays a wide range of information, and the keypad can be used to select various operating modes, including three different
steering modes. A Longitudinal Stability Indica-
tor for the machine’s forward stability provides a constant check on load safety with a cutout for the extend and lift down
functions. Service access points are conve-niently locat-ed under the
engine cover, and routine daily mainte-
nance is now reduced to checking fluid
levels and a walk-around inspection.
Hitachi unveils ZX14-3 Hitachi Construction Machinery (Europe) NV has introduced the new ZX14-3 to its Zaxis-3 range of excavators and fills a gap in the 1-2t class mini excavator sector. The ZX14-3 is compact and light and can be transported by trailer. It has a three-cylinder 10.7 kW engine with a larger exhaust to comply with the European Stage III A emis-sion regulations. Performance is enhanced by innovative hydraulics, similar to those found in Hitachi Zaxis medium excavators. The

new model’s control levers are responsive and allow continuous
operation with less fatigue. Noise and vibration are kept to a minimum due to an improved tread pattern on
the rubber tracks.
New steel tracked loaders Bobcat has launched new steel tracked versions of the T250, T300 and T320, compact tracked loader range as an alterna-tive to the conventional rubber tracked configurations. The steel-tracked versions are claimed to be unique due to their ability to work with o ve r 40 different attachments
in a wide variety of appl icat ions. They offer alternatives to dedicated crawler dozers, which can only be used for bull-dozing applications. All three machines have better turning abil i ty than larger tracked machines. The s tee l t racks, which are 340 mm wide, offer
up to three times the track life of rubber tracks
in heavy-duty applications. Compared to the rubber tracked versions, the steel tracked T250, T300 and T320 models have an increase in operating weight of approximately 280kg and provide a 37-45% increase in pushing force across all three models.
In addition to excellent traction, the steel tracked ma-chines offer high digging power and good dozing and grading capabilities. The sealed and lubricated track chain has a 50% reduction in internal bushing wear, a quieter operation and lower fuel consumption than the sealed only chain. Other aspects include triple grouser track shoes and the 340mm wide pads
provide a good balance between traction and flotation. The angled top plates offer easy cleanout, with an open area around the sprocket and under the top roller.
Hitachi’s two new wheel loaders Hitachi has introduced two new wheeled loaders the ZW140 and ZW150 to join the ZW180, ZW220, ZW250 and ZW310 mode l s. Equipped respectively with 96kW and 107kW engines the ZW140
and ZW150 are fitted with hy-drostatic transmission. This offers greater mobility
when fully loaded, smoother control on gradients and under acceleration and deceleration, the company claims. These

benefits are achieved due to the twin-motor system, which allows greater operating efficiency from powerful traction at low speed, to a maximum speed of 39km/h. In addition, the HST system’s speed selector provides a range of four maximum travel speeds to suit the particular requirements of each job. In addition when the first range is selected, the maximum speed can be adjusted to four incremental levels, which increase efficiency and simplify operation in confined spaces. The ZW140 and ZW150’s optimum traction force can also be set to increase efficiency. The new models offer four work modes that can be selected according to the needs of the job and operator preference. The electronic matching control senses the hydraulic pressure and controls traction force, which optimises productivity while keeping tyre wear-and-tear and fuel consumption to a minimum.
New 1 to 2t mini-excavators Bobcat continues its excavator development with the launch of the new E14 and E16 mini excavators. Featuring as standard a retractable undercarriage, the E14, equipped with canopy and bucket, has an operating weight of 1.3t and has a maximum digging depth of 2.3m. The E16 is available in two versions. Equipped with canopy and bucket, the E16 base model with fixed undercarriage weighs of just over 1.5t with a maximum digging depth of 2.4m. Equipped with canopy and bucket, the E16 with the optional factory installed retractable undercarriage and long dipper stick has an operating weight of 1.55t and digging depth of 2.6m. High digging perfor-mance is enhanced by the stability provided by the dozer blade and the low centre of gravity of the ma-chines. The E14 and E16 models, which utilise the cylinder-over-boom design, are powered by a 3-cylinder 9.9 kW Kubota D722 engine.

Conjet hydrodemolition equipment was used to remove damaged concrete from the faces of the viaduct’s rectangular concrete piers, which rise up to 136m from the valley bottom to the steel deck, followed by replacement with a new and thicker concrete skin.
A link between Parma and La SpeziaThe 960m long twin steel deck viaduct, which is supported on eight reinforced concrete hollow pillars, is a major structure in the link between Parma and La Spezia on Italy’s Mediterranean coast, 100km south of Genova. The spectacular viaduct was opened in 1975, but inspection showed the bridge piers were suffering from extensive calcium chloride decay, forcing the Italian Highways Authority and the Highway Engineering Department of Cisa Ltd to carryout extensive repairs and strengthening.
The specialist hydrodemolition contractor SEI-Idrojet, working for the main viaduct repair contractor A.B.C.Construczioni S.P.A., carried out the concrete removal on one pier at a time. The repairs were performed from a special, purpose built cradle and working platform that wrapped round all four sides of the piers. The ends of the platform were adjustable to compensate for the changing width of the tapering piers. The whole platform was supported and raised and lowered on wire ropes, which went up to pulleys on a steel support cradle at the top of the pier and back down to four synchronised winches anchored at ground level.
Conjet modified a standard robot feedbeam to fit onto and run along a rack on the inner sides of the platform in the fixed space be-tween the pier and the platform. A Conjet Computer Control Unit, also mounted on the platform, was used to control the feedbeam and integral jetting nozzle. A Conjet 345-400kW Powerpack at ground level provided the high-pressure water at 1000bar and flow of 200l/min to the feedbeam’s nozzle. The feedbeam and nozzle, travelling back and forth along the platform’s rack, selectively removed dam-aged concrete to a depth of 70mm and below any exposed reinforc-ing. The process continued on one face of a pier as the platform was

slowly raised to the top. On completion of concrete removal from one face, the Conjet feedbeam was moved to another side of the platform for the process to be repeated on all four faces. SEI-Idrojet operations and site manager Enrico Mariotti was responsible for devising and controlling the hydrodemolition process.
On completion of concrete removal another team followed on placing additional reinforcement to all sides of the tapering pier. Shuttering panels 1.8m high were then fixed round all faces to support a new 220mm thick skin of self compacting concrete pumped into the form work. After the concreting the formwork was repositioned for the next lift for the process to be repeated to the top of the pier.
On completion of repairing and strengthening a pier with an additional layer of concrete, the working platform was dismantled and re-erected on the next and then subsequent piers for the hydro-demolition and concrete repair process to be repeated.

An Aqua cutter HD RA system with a robot arm from Sweden’s Aquajet Systems was chosen to remove the lock’s poor quality, cracked concrete.
The Guttenbach Lock was first built in 1939 and a second added in 1955. The middle wall separating the locks is 1.2m wide. With excessive cracking on both sides of the wall, loadings were a critical factor in determining the method of removing the concrete.
Hydrodemolition specialist Luckei Beton-frästechnik based in Bendorf, Germany, was awarded the contract for the concrete removal and opted to use its Aqua cutter HD RA robot, weighing 1.7t. Luckei is using the hydrodemolition robot to remove concrete to a depth of 400mm along the full 100m long lock wall.
The compact and versatile HD Robot Arm is prov-ing ideal for working on the 1.2m wide strip. It features Aquajet’s improved EDS cutting head, which keeps the set

distance from the nozzle to the surface independent of the selected lance angle and optimizes the removal rate and saves energy. All hydraulic movements are by remote control a safe distance from the unit.
Hydrodemolition ensures no rebar damage, minimises risk of removal good concrete, eliminates dust and crystalline silica pollution and leaves a superior bonding surface. It is also substantially faster than mechanical removal methods and is also considerably less labour intensive.
Together with the robot, Luckei is operating a high pres-sure Power Pack with the capacity of 250 litres/min of water at 1000 bar pressure. Water is taken from the river and filtered and after use is filtered again and returned to the river.
A temporary gate barrage has been placed across the upstream end of the lock closest to the riverbank and water pumped out to provide a dry lock for Luckei to prepare the 9.5m walls.
Luckei will then use hydrodemolition for the severely cracked walls and is considering using Aquajet’s recently introduced hybrid robot offering an extended vertical cut-ting reach of 9m.
Once new concrete has been added, and additional strengthening completed with the installation of 20m deep pre stressed anchors along both sides of the lock, new gates will be installed for the lock to resume normal operation.
The River Neckar is 367km long and the fourth largest tributary of the River Rhine, which it joins at Mannheim. It is navigable for cargo ships up to the port of Plochingen, about 200km upstream from Mannheim and features 27 locks dropping the river from 247.32m to 86.50m.
With barge traffic using the Guttenbach Lock every 10 – 15 minutes between 7am – 10pm, plans are underway to increase the length of the lock from 100m to 130m to cater for the next generation of longer barges.
Main contractor for the Guttenbach Lock project is Echterhoff GmbH & Co Kg and consulting engineer is Glass Bauuternehmung GmbH.

US manufacturer Jet Edge’s, in St Michael, Min-nesota, USA, announces now a series of new products for waterjet purposes.
Ultra DeckblasterUltra Deckblaster waterjet surface preparation machine uses ultra-high pressure waterjets to quickly blast away old paint, coatings, grease and dirt from steel decks and concrete floors without using hazardous chemicals. Resembling a lawnmower, the self-propelled Ultra Deckblaster operates at pressures up to 3,800 bar (55,000 psi). Typical applications include removal of polyurethane paint or non-skid coatings from factory floors, ship decks, paint booths and parking ramps. The Ultra Deckblaster also removes accumulated spillage such as grease, oil and overspray.
The Ultra Deckblaster portable water jet system utilizes UHP water supplied by a Jet Edge waterjet intensifier pump. Hydraulic pressure activates the motor to spin the spray bar assembly and open a high-flow water valve supplying fluid to the mani-folds. The water travels through a high-pressure on/off valve and high-speed swivel before entering the rotating spray bar. Multiple water jet orifices direct UHP water over an 460 mm (18”) wide cleaning
path as the machine advances. The spray bar ac-cepts a variety of standard jet manifolds.
Operators have total control of the rotation speed, drive speed, forward/off/reverse, water and rotation on/off of the spray bar. Easily accessible knobs control forward/reverse and bar rotation speeds. A manually actuated valve does not allow operation of any function unless the safety lever is depressed. The hydraulic-powered wheel drive offers additional operator control and comfort and can be easily disengaged for free-rolling applica-tions. The spray bar height is adjustable.
New Hydraulic Versacutter for Mobile Waterjet Cutting
Jet Edge has also introduces its new Hydraulic Versacutter portable waterjet cutting and bevelling system. The Jet Edge Hydraulic Versacutter is a hydraulically controlled mobile waterjet system that moves along rigid or flexible track to cut flat or curved surfaces. It cuts with a 4,100 bar (60,000 psi) abrasive waterjet. The Versacutter is ideal for cutting pipelines, steel reinforced concrete, reactor vessels and fabricated metal structures. It cuts with-out flames and does not generate heat. This makes it possible for operators to cut in areas where flames
are restricted. It also eliminates heat-affected zones. Jet Edge’s Hydraulic Versacutter water jet system is powered by Jet Edge’s 4,100 bar (60,000 psi) waterjet intensifier pumps, which are available in electric or diesel models up to 280HP.

Many captains of industry, be they from the North America, Europe or Asia, have expressed surprise at their Russian coun-terparts’ young ages. It appears that vast fortunes and brilliant careers can be made much faster there than in the rest of the world. However, before jumping to any conclusions it should be recognised that this basically applies to those who started their careers in the 1990s. During that tumultuous, yet highly entrepreneurial decade, businesses sprouted like mushrooms after a downpour. When the Iron Curtain collapsed, a whole new generation of young and rigorous businessmen emerged, who began to import Western cutting-edge technologies into a country with the industrial base in a total shambles. The then Russia was awash with make-or-break opportunities for aspiring wheelers and dealers trying to make as much hay as possible while the pallid northern sun was shining.
New millennium’s people
Alexei Melnik and Alexei Kudryavtsev, who head St.Petersburg-based Deconstruction North-West, are young and both in their early 30s. Still, they were born just a few years too late to jump on the 90’s bandwagon. The other difference is that they have quite consciously chosen break over make and have no regrets. It was already six years into the new millennium, when the two launched their company dealing in Brokk robots and offering robotic demolition services in the northwestern part of Russia.
Peculiarities of the
national robotic demolition It is often said about Russia that it is a country that works in mysterious ways. This contention is highly debatable, but the way the Brokk business has gone there was just as special as one could have expected. While everywhere in the world construc-tion has been, and remains, the main field of application for Brokk technology, in Russia it was steel mills and metallurgical plants that were first interested in robotic demolition. Thriving on high prices for steel and metals, they began to use Brokk robots to remove burnt-out linings from their furnaces. Russia’s construction society was largely unaware of robotic demolition, and Alexeis saw it as a promising niche.
Having started out as a Brokk dealer in northwest Russia,
they soon realized that performing demanding demolition jobs would be the best way to promote Brokk’s brand in the region. In the formative year of 2006, the company staff boasted just its two founders, also functioning as sales managers, a civil engineer and an operator of the only demonstration Brokk 180. By 2009 Deconstruction North-West had sold 15 robots in St.Petersburg and increased the personnel several-fold.
When asked about the attitude of Russian specifiers towards Brokk, the managers said that despite interest from engineering quarters known for their open-mindedness, there is still a lot of backward thinking in the industry. Even now, many demolition projects in Russia are designed with manual techniques in mind, and both specifiers and contractors are reluctant to ditch the conventional methods that they have been using for decades. Sometimes it takes much convincing to make the specifiers see that they save virtually nothing by using obsolete and often dangerous solutions.
To remain competitive and promote its cause, Deconstruc-tion North-West has to do its Brokk jobs on the same price level as the manual demolishers. The technology’s efficiency and versatility help keep the operating costs down. As practice shows, Brokk is especially cost-effective when used together with other modern demolition methods like diamond cutting.
Powerful, versatile and safe
The old mentality may be dying hard but it is bound to go anyway. Deconstruction North-West has now solved enough difficult projects to prove Brokk’s superiority over time-consuming and ineffective manual techniques. The most vivid example, perhaps, is the removal of the two top floors of a hotel in Vasilievsky Ostrov, one of the most original and romantic districts in St.Petersburg. On this job, the company worked alongside another demolition contractor. That company used dated impact methods, while Deconstruction North-West oper-ated two Brokk 180 units. It was the modern-day approach of Deconstruction North-West that allowed its general contractor to complete their half of the job two months ahead of their

PDi Editor Andrei Bushmarin recently met with one of Russia’s young demolition companies Deconstruction North-West. The company was started in 2006 and in a few years showed tremendously fast growth.
The picture above shows the renovation of the Blagove-shchensky Bridge (former Lieutenant Schmidt Bridge) in St.Petersburg.

competitors. Operational safety ensured by the remote control option provided another invaluable advantage. Occasionally operators of the rival company were seen jack-hammering the beam on which they were standing. The very nature of Brokk rules out the possibility of such a gross violation of the most basic safety precautions.
Robotic demolition also proved useful on a reconstruction project of both logistical and cultural value. The Blagoveshchen-sky bridge (aka the Lieutenant Schmidt Bridge), which links Vasilievsky Ostrov with the mainland, was the first permanent bridge over the Neva River, the main water artery of St.Petersburg. The eight-span bridge is famous for its exquisite cast-iron railings. An expansive renovation project for the bridge started in 2006. Deconstruction North-West did its bit by helping dismantle a bridge’s abutment three weeks ahead of schedule using one Brokk 180. Safety was a major concern on this job, since all operations had to be performed on the bridge abutments’ edges, inches above the water surface, with the risk of personnel falling into the river. The hardness of the concrete presented another problem. The material, which had soaked up much water over the centuries, became so tough that even jackhammer drills were repeatedly broken.
All attachments ablaze, a Brokk robot can pick on any man-made structure, no matter how formidable it may be. Even a World War II pillbox built near an operating bridge’s abutment on the outskirts of St.Petersburg could not withstand a Brokk. This defence facility was heavily reinforced with 36mm diameter rebar, steel channels, and frontal armour plates from cruiser guns. The specifier set a challenging task to dismantle the pillbox to a strict 10-day deadline. This requirement effectively rendered useless a demolition option involving hydraulic wedges, which was first considered, since it would take at least two to three weeks to ac-complish the task that way. Diamond cutting was also evaluated and rejected because of its high cost on this particular project. Since the robotic demolition technique offered the best solution, both in terms of cost and deadline, it was chosen for the task, which Deconstruction North-West successfully completed.
Brokk goes underground
Metro is another industry in Russia that has appreciated the capabilities of robotic demolition, says Alexei Melnik. Brokk was an immediate success with the state entities responsible for underground public transportation. The state unitary enterprise St.Petersburg metro alone has bought seven Brokks in the last 18 months. The enterprise was amazed at the winning combination of efficacy, mobility and small size of Brokk machines. Robots can easily get to any hard-to-reach spots, which are numerous in the
subway network. They can also be delivered underground within a matter of hours, which is totally unimaginable for cumbersome machinery traditionally used by the enterprise. Besides, robots can work from scaffolds in tunnels of any diameter, with their performances exceeding the designed parameters of metro’s maintenance equipment. The St.Petersburg Metro has recently commissioned four new stations in the city, a project on which Deconstruction North-West closely co-operated with the state enterprise on a consulting basis.
“Greening” the demolition businessFor Deconstruction North-West, environment protection and green technologies are not merely the buzzwords of the day; it is a prerequisite for the company’s survival in the tough demolition market. “If a demolition firm wants to remain competitive, it is expected to provide its specifiers with the whole service package, from demolition to site clearance to management of often haz-ardous waste,” says Alexei Melnik. “Again, the Brokk technology proves indispensable here, since it precludes any contact with dangerous materials.” In line with this Deconstruction North-West pays special attention to ecological aspects of its demolition operations. It means using Brokks instead of labourers wherever possible, assisting in developing environmental feasibility studies, identifying hazard classes and performing other tasks associated with environment protection.
Deconstruction North-West’s expertise also includes handling asbestos jobs. Asbestos figures high on the current list of industrial killers, and Brokk technology offers viable and safe solutions where other techniques may entail a real threat to health. Deconstruction North-West recently assisted on a job in St.Petersburg, which called for the removal of 5km of asbestos-lined pipework. With high wind sweeping through the site, operators’ safety was in serious jeopardy. Given this, robotic demolition was chosen as the only feasible approach. The robots equipped with shears cut the pipework into 5m sections, which were taken away for landfill. No labourer was involved in the job, the only men onsite being Brokk operators who wore PPE at all time.
Having witnessed firsthand the competitive benefits of robotic demolition, many major players in Russia’s Northwest area now view it with a different perspective. With the Brokk idea firmly imbued in the local market’s collective mind, Deconstruc-tion North-West is all set to expand its operations further a field. The company has recently announced its first project in Moscow. The management is positive that its marketing strategy will prove successful in the capital, too.

“Brokking” the way forward
Here’s RamtecFor some people the Finnish manufacturer Ramtec is perhaps a completely new name. However, the company dates back to the 1970s even if it was founded in 2002. Ramtec, located in Lahti, Finland, was since the 1970s a development and production section of Rammer, today Sandvik.
Once a part of Sandvik/RammerIn 2002 Ramtec became an independent company through a management buy-out from Sandvik. Ramtec still has a close co-operation with its previous owner and manufactures several of the basic components of Sandvik’s demolition attachment and breaker series.
After the management buy-out Ramtec started to develop a line of hydraulic handling, recycling and demolition tools, called the Robi Series. “We have invested the time necessary to build up our own strong line of attachments, but we are not in a hurry and we want to meet our customers’ exact requirements. Our first new products were invented in 2003 but launched globally during 2008. They have been very well received by the market,” says Ramtec marketing manager Vesa Santala.
Four Robi Families
The Robi products are divided into four groups. The DG-series has five models of demolition and sorting attachments, the DG6r, DG8r, DG15r, DG20r and DG30r, which cover
weights from 250kg to 1.77t and suitable for carriers between 2.5 to 40t. The concrete crusher series CG contains three models; the CG20r, CG35r and CG50r. Weights are 1.8, 2.6 and 3.5t and suited for carriers between 10 to 60t. CG35r is completely new for the international market and was launched at the Intermat show in Paris this spring. It has been sold on the Finnish market though for about two years. The HG-series are the three sorting grapples, HG10r, HG20r and HG30r weighing 1.6, 2 and 2.6t, and developed for carriers between 10 to 60t. The last series are the Multi Master screening buckets for screening and recycling of different types of building materi-als. Multi Master is available in three different sizes, MM104, MM154 and MM254. MM104 weighs 1.7t and has a screening capacity of up to 1.4m3 and screening area of 1.2 m2. MM154 weighs 2.3t and has a capacity of 1.9m3 and a screening area of 1.8m2. The biggest unit is the MM254, weighing 2.9t. It has a capacity of 3.2m3 and a screening area of 2.7m2. The buckets have been developed to screen and crush soil, wood, bricks and other types of demolition waste and glass. All Robi products, except the Multi Master buckets rotate 360°.

up a worldwide sales network. “Not so long ago we attended our first trade show in our hunt for distributors and agents. The reaction from the market has been very good and slowly we are getting represented in several countries in Europe, former Soviet states, Middle East and parts of Asia,” says Vesa Santala.
The Nordic and the Baltic states also have a high priority. Ramtec hope to build a strong foothold there with a home market that contains all the Nordic countries. Ramtec has attended several larger shows recently, such as Bauma China 2008, CTT in Moscow, Intermat and Maxpo. Next year they will attend Bauma 2010 in Munich, Germany.
Unique and focused ownership
The new Ramtec was founded as a result of a management buy-out from Sandvik and four of the seven owners work in the company. “This gives us a unique position as the owners of Ramtec work or have worked in the company. The people behind the company are very interested it its products, cus-tomers and the segments where we are active. If we would have been owned by an investment company things would have been very different,” says Vesa Santala.
The development and the manufacturing of the Robi
ranges is carried out in modern facilities built 1996 but at that time owned by Rammer and later Sandvik. The current turn over for Ramtec is close to EUR9.5M. During the last four years the turn over has increased by more than EUR4M. The Finnish market represents around EUR1M.
“We are very optimistic about the future. The market has received our products very well and our growth continues at a fast pace. But it is also difficult to grow in the way we are doing now. It is important to find the right partners with the same goals as us. While expanding we cannot forget to develop and improve our existing and new products for demolition, recycling, handling and screening,” says Vesa Santala.

High-performance dust suppression equipment has helped one of the UK’s leading demolition firms remove 20 buildings from the former University of East London campus without a single dust complaint, despite the extremely brittle, old con-crete and close proximity to occupied structures. Although the conditions could have presented a nuisance for workers or nearby residents, crews from demolition contractor Syd Bishop and Sons were able to successfully manage surface dust and airborne particles with a powerful misting system from the US company Dust Control Technology. The demolition effort took a year to complete, making way for more than 1,000 new homes on the site.
A delicate demolition workThe project, described as delicate demolition work by the company, required that some of the buildings be surgically separated, with one portion being removed and the other remaining for re-use or renovation. “We literally had to cut away adjoining structures, demolishing some parts and leaving others intact,” said Syd Bishop director Tom Bishop.
In addition to the size of the job, part of Bishop’s challenge was containing the sizable volume of dust generated by the firm’s activities.
Syd Bishop goes to university“The DustBoss system not only minimized dust on the job, but it helped us through the planning process,” says Tom Bishop. The concrete was so fragile that cab windows on some of the company’s equipment had to be protected with screens to prevent breakage from flying chips.
Bishop’s crews were also faced with some major utility-related challenges. “There were three electrical sub-stations on the site, one of which was still in use,” adds Bishop. “The site was also criss-crossed with gas lines, and no one seemed quite sure of their exact location. Some of the gas mains never had meters, and there was no easy way to cut them off. In the end, they had to be sealed from outside the perimeter of the site. The process took months to complete.”
Extensive fleet of demolition equipment
Covering an area of about nearly 25 acres, demoli-tion of the former University of East London started with soft strip and asbestos removal programmes at the beginning of the year. The company then called on its extensive fleet of demolition excava-tors, including a Hitachi ZX600 equipped with a 36m boom and a ZX400 fitted with a 24m boom. Both units were armed with Verachtert VT pulverizers.
A Hitachi ZX470 equipped with a 4m3 bucket was used to dig out foundations, and the reinforced concrete was then broken down by a ZX280 with a Komac hammer and processed by an Extec C-12 crusher. All of the debris was retained on site for processing and potential re-use.
“The recycled material was reduced to 25 mm and stocked for piling mats and sub-base for
the new development,” added Bishop. Any waste that did not have a use on site was transported to the company’s main recycling facilities at Longfield, where it was separated by picking stations, water baths and various automated techniques to mini-mize the amount of waste going to landfill.

Atlas Copco assists with bridge demolition
number of places including the demolition of a
bridge near Randersacker. The old bridge, built in 1964, was blown up and replaced with a much wider structure just 3m away.
After the 540m long bridge was blown up, the B13 road underneath was re-opened to traffic within 36 hours of the demolition. This was pos-sible after about 1,500m3 of reinforced concrete was removed and crushed and another 800m3 of material protecting the road surface was also
removed. A total of 25,000m3 of reinforced concrete had to be removed.
The contractor Ruppert GmbH & Co. KG Erdbau + Abbruch from Frickenhausen has used eight Atlas Copco medium to heavy hydraulic breakers weighing between 1.2t and 7t for
the job. “With these attachments we were able to cope with the 25,000m3,” says company manager Florian Ruppert. “On the other side of the bridge a railway track intersects with the old bridge and this part of the bridge could not be blown up. For this particular demolition job we purchased the Atlas Copco CombiCutters CC 2500 U and CC 3300 U. We attached them to Liebherr 954 and 974 long reach excavators and demolished this bridge section from below.” The rubble will be a recycled in their own recycling plants and the B 13 was cleared for reopening to traffic much earlier than scheduled.

“Husqvarna and Pentruder are heating up the climate”There has only been a
few new wall and wire
saws launched this year
and include Pentruder’s P38
wire saw and CBK wall
saw and Husqvarna’s WS 482
HF wall saw.
Since our last feature on concrete wall and wire saw-ing equipment there has only been a few launches of new products. Tractive, now in the process of focusing on the Pentruder name has, however, been quite active. The company has been developing new products and starting up new subsidiaries in the US, UK, Norway and Sweden and building up strong service and support networks in their markets. To-gether with Husqvarna launching their new WS 482 HF the Swedish manufacturers are heating up the climate before Bauma 2010. The show in Munich next spring will be the launch pad for a lot more new products.
CBK straight to the heart of the contractors
New from Pentruder is the new and unique P38 wire saw and the budget model of the Pentruder high cycle wall saw the CBK. Contractors that have already used the CBK say that it offers an unbeatable price to performance ratio. It is a single speed saw available in 15, 18, 22 and 27 kW and can take up to 1.6 m diameter blades.
Pentruder now has a range of five HF saws, including the new CBK, the P38 and the brand new Pentruder modular concrete cutting system. These can also be used with the Pentruder standard rail system and all the equipment can integrate with each other. The official launch of the new Pentruder Modular Concrete Cutting System will be at the World of Concrete 2010.

Brand new HF gear from Husqvarna!
Also new from Husqvarna is the electric wall saw WS 482 HF. The powerful WS 482 HF accommodates larger blades and offers the best power-to-weight ratio in the market, allowing cutting and drilling
professionals to work faster and more ef-ficiently.
The WS 482 HF, operated by radio remote control, is based on the same technology as the WS 440 HF launched last year, but can use blades up to 1.6m diameter. It has a new two-speed gearbox combined with variable speed transmission, which allows the optimum speed to be set according to blade diameter, blade type and cutting material. Husqvarna has optimized the power-to-weight ratio and developed a saw that is lightweight and flexible while at the same time being extremely powerful.
19 kW and only 28 kg!“The WS 482 is incredibly powerful. You get 19 kW at the blade shaft with a 32 amp fuse, despite the saw weighing only 28 kg. A great advantage is that if only 16 amps are available at the workplace, the WS 482 still delivers a high power of 9 kW. No other electric wall saw on the market today can do this,” says Husqvarna Construction Products Construction Equipment Product Manager Lars Gustafsson.
As with all Husqvarna products, the WS 482 HF was developed to make the operator’s work easier and more efficient. The saw is of modular construction, making it easy to hang on the wall and transport. It is possible to cut on both sides of the track. Its direction of rota-tion can be selected so that the water always sprays in the desired direction, irrespective of sawing from either side of the track.
Specification: WS 482 HFThe water- cooled electric motor generates a total of 19 kW to the
shaft.
• The shaft has a continuous speed setting and is operated
by radio remote control. This gives full control over the
sawing process and freedom of movement at
the workplace.
• Two-speed water-cooled
gearbox for a wide rpm range.
• Short distance between
track and blade for a
straighter cut and less
wear on saw and blade.
• Slip clutch for all
moving parts.
• Symmetric track
makes it possible to
cut on both sides
of the track.
• The rotation
direction of the
blade can be
set by remote
control, giving
the water spray
the desired
direction.
“Husqvar-na’s new wall saw-ing system, W S 4 8 0 HF, offers t h e b e s t power-to-weight ratio on the mar-ket,” says Husqvarna C o n s t r u c -tion Products C o n s t r u c -t ion Equ ip-ment Product Manager Lars
Gustafsson.
“Husqvarna’s new electric wall-saw allows cutting and drilling professionals to work faster
and more efficiently. The small distance between track and blade gives a straight cut with less wear on saw and blade,” says Lars Gustafsson.
The PP 480 HF is the power pack for the WS 482. It weighs 23 kg and easy to transport. The WS 482 HF powered by the PP 480 will be
launched at the end of the year.www.husqvarnacp.com

“There has been an increasing number of excavation jobs in recent years and we have also taken on demolition projects from time to time,” says company founder and managing director Costas Papacostas. This gave Costas Papacostas & Sons Ltd, in Limassol the idea of starting out in the lucrative line of business themselves with their own crusher. Not only do they have to handle material that accumulates on their own job sites, Cyprus also has tipping fees and they can help other companies to save money by letting Costas Papacostas & Sons recycle their material.
Chose Rubble Master“We were convinced that we needed a high-performance impact crusher that could produce high-value aggregate with a throughput of up to 200t/h. It was also important for the crusher to be able to process a variety of materials from dif-ferent job sites.”
Costas Papacostas contacted the Rubble Master represen-tative in Nicosia, Alexander Dimitriou & Sons Ltd and shortly after visited Rubble Master headquarters in Linz, Austria. It was also here that the decision was made to go for the RM100 crusher and TS3600 final screen combination.
A service engineer from Rubble Master and dealer Alexander Dimitriou & Sons Ltd were present at the com-missioning and training in September 2008 and have since provided backup through the Rubble Master Lifetime Support programme.
“For us, fast spare part supplies through an experienced regional dealer was a crucial factor in making our decision to buy,” says Costas Papacostas. “After all, the availability of the machines is of extreme economic significance. We are fully satisfied with Rubble Master and Alexander Dimitriou & Sons Ltd.”
“A good profit”So far the machines have been used mostly at the company’s recycling yard and thousands of tons of sorted material is in storage. After just one year, recycling newcomer Costas Papa-costas is more than satisfied with his decision to buy mobile Rubble Master compact recyclers: “The machines are used to capacity and earn good profits. The manufacturer’s specifica-tions, especially in terms of both the promised throughput and also the costs, have proved to be true in day-to-day operation. The RM100 is remarkable when it comes to consumption as it needs only 22 l/h of diesel, at the most, for 200 t/h. Plus we find ourselves travelling more and more to job sites with the machines for on-site recycling. This adds to the range of applications. We are thoroughly satisfied and can see how right we were to take the decision to start out in mobile recycling as a new line of business!”

D J Laing is one of the UK’s wood waste recycling specialists and use Doppstadt chippers and shred-ders in their wood waste treatment processing plants. The company has recently taken delivery of their fifth Doppstadt, a Doppstadt DZ-750 Kombi combination slow and high-speed shredder from Blue Scotland for use at its Petterden Recycling Centre. The DZ-750 Kombi was chosen by DJ Laing because it is specifically designed and built for the shredding of wood waste and is also ideal for the production of bio fuels.
The Doppstadt DZ-750 Kombi is a mobile shredder combining slow pre and fast fine shredding. Integral twin overband magnets, for tramp metal removal, hard metal flail tips, a hydraulically controlled fine shredding comb and a remote control are all standard equipment. The drive unit is rear-mounted and the slewing cooler features a large reversible self-cleaning fan wheel. Tools, flail tips and the fine shredding basket are easily replaceable.
Italy will be one of the top football teams at the next World Cup to be held in South Africa in 2010. One of the companies supplying the machinery to assist with building the new stadium in Johannesburg will be the Italian company MB s.p.a based in Vicenza. The company’s bucket crushers are currently being used on the construction site for the Soccer City Stadium where the World Cup final will be held on 11 July 2010.
“We were very excited when, together with our South African distributor High Power Equip-ment Africa, we won the order to supply the bucket crushers for construction of the stadium where the opening and closure ceremonies for the 2010 World Cup will be held,” commented MB s.p.a managing director Guido Azzolin. “It was a real surprise and made us proud of our products and proud to be able to bring a piece of Italy to this major world event.”
A meeting with the South African dealers took place several years ago when MB de-cided to venture beyond national boundaries. Many visits followed and eventually led to MB exporting a large number of machines to South Africa. The presence of MB equipment in South Africa made it possible for the company to contact other potential customers from other African countries.
After numerous visits to construction sites in Johannesburg, the company discovered that work on the large construction complex for the World Cup was generating considerable quantities of inert material. This led to the idea of proposing the bucket crusher, an idea that was received by the works management with
a degree of interest that went well beyond the company’s expectations.
“We are proud to demonstrate that Italy has much to offer the world, particularly for these large-scale events,” adds Azzolin.
As a result of major investment in research MB is able to produce technologically advanced bucket crushers with unmatched performance. This is why Liviero Civils chose MB products for the construction of the largest stadium in South Africa with a capacity of almost 100,000 people. “In a period of global economic crisis like the present, our machines in Johannesburg demon-strate that companies that invest in research and technology and propose cutting-edge products,
Wood recycling and biofuel production
MB at the 2010 World Cupwill always be successful and can establish a strong presence even in such elite segments as that of large scale construction,” says Azzolin.

In Salzburg, Austria, the expansion of the S-Bahn urban railway has been progressing in recent years. To finalise the works, the remaining narrow point had to be extended. Around the central railway station the old railway bridges were torn down and replaced with new. The bridge, with its five lines, over the Rainerstrasse was the first one to be replaced, as it was too weak for the new S-Bahn and the high performance railway line to Munich.
Challenge to keep trains runningThe challenge was to keep the trains running to Germany and Western Austria during the construction works, so a part of the bridge had to remain open with two lines. The schedule was to build one half in 2009 and the other in 2010. The first part started in March 2009. The two remaining lines and the bridge structure had to be separated from the remaining section. As this was

WELCOME TOOUR KIND OF PLAYGROUND
OUR KIND OF PLAYGROUND is often a very dangerous environment and there are no good arguments for exposing you or your staff to falling debris or dangerous vibrations.Our demolition machines are radio controlled and electrical-ly driven so that you are not exposed to dangerous fumes. Another thing which makes the machines even better is that you can demolish up to 5 times quicker than tra-ditional sawing and cutting methods. Time is, as we all know money!

EDT EURODIMA assists in bridge upgrade
a concrete lined beam bridge, diamond technol-ogy was chosen for the task. The local concrete cutting specialist Seidl, a EDT EURODIMA and was assigned to carry out the work by the site’s principal contractor.
To avoid disturbance to traffic under the bridge, the work was scheduled on weekends only. The Rainerstrasse was blocked from Saturday 4a.m. until Monday 5a.m. and the concrete cutting was arranged for Sunday from 5a.m. to 3p.m during a traffic diversion.
Planning was critical to carry out the tasks in the time frame. Seidl’s concept was to do the separating cut with three hydraulic 30kW wall saws and an electro-pneumatic wire saw. The cuts were 20m long and 400mm deep and 600mm deep at the foundations. In the range of the flyover 12 beams and some steel plates ranging from100mm to 300mm also had to be cut.
Diamond tools with DURAMANTIn addition two openings of 1m x1m x0.8m also had to be cut for bridge underpinning. Here a steel beam had to be cut, as well as concrete covered steel underpinning at the pedestrian passageway. The big EDT EURODIMA wire saw wb12s was used for this task with DS40FBLUE diamond wire with 40 beads per running metre, 10.5 mm outer diameter and 2 mm active wear layer.
Seidl consulted the EDT EURODIMA technician and chose to use the WS30 diamond saw blades with the new DURAMANT® segments, with width 5 mm for 600 mm diameter, 4.7mm for 825mm diameter and 4.4mm for 1200mm and 1500mm diameter saw blades. The EDT EURODIMA wall saws WM90 with hydraulic unit HA300 in combination with the DURAMANT tools accomplished this challenging task reliably as usual.
Seidl used six concrete cutting experts to operate all the machines. Despite the change from wintertime to summertime, with that night being shorter by one hour, work started early at 5a.m. and the task was completed by 2.30p.m. Good coordination was needed to use the machines economically.
Regardless of the bad weather, all concrete cutting tasks were accomplished to the satisfaction of the principal contractor.

Easy regulation of the working conditions:
Low vibrations and noise level:
A complete range of breakers up to 10,000 lbs operating through nitrogen and oil to deliver very high energy and productivity along with recognized reliability and low oil flow requirements.The high back-pressure allowed makes initial installation and working set-up very easy.
blow energy vs. frequency, working pressure are easily adjustable to meet optimal breaking performance.
a sophisticated system of internal shock absorbers completely isolate the gun from the external casing.
Diamanttek hired the 20 UTL rig from Castellan to vertically drill 24mm diameter holes, 300mm deep on a rectangular grid pattern to take resin bonded threaded rods for the steel plates supporting the rail tracks. Diamanttek had to drill the holes and install a pair of rail tracks in one portal framed building, which is 190m long and two others at 150m long.
“The rail installation has been critical to enable the gantries to be erected on time and the E-Z Drill has proved to be fast, very cost effective, easy to operate, user friendly and very simple to maintain,” says Chris Holloway. “There is absolutely no risk to the operator of hand or arm vibration. The operator training for the 20 UTL has been so simple. The operator can easily drill 60 holes/hour or 480 holes/day with the E-Z Drill. The actual drilling for each hole only takes about 38 seconds and about 20 seconds to move and reposition for the next hole. So it is easy to drill a hole a minute. We did drill a few holes with a normal hand held drill, which took about 10 minutes/hole or 6 holes/hour. So it’s fair to say the 20 UTL is at least 10 times faster than a hand held drill and considerably cheaper.”

E-Z drilling for UK’s DiamanttekThe specialist UK diamond drilling, sawing and demolition contractor Diamanttek, based in Bolton, Lancashire, has made considerable time and cost savings and achieved substantial environmental and safety benefits by hiring an American E-Z Drill pedestrian controlled drilling rig for use on a vast waste processing and re-cycling project in Lancashire. Diamanttek used the E-Z Drill 20 UTL rig to drill about 4,000 vertical holes into the reinforced concrete floor slabs of three huge buildings to install studs to support rail tracks for special overhead gantry mounted waste rotovators. The drill, hired from Castellan in Milton Keynes, proved so success-ful it has been transferred to another similar waste processing plant at nearby Leyland to perform an identical operation.
Eliminate risksDiamanttek has also found the 20 UTL rig to be more accurate, versatile, efficient and en-vironmentally acceptable than traditional hand held drills. The company says that the simple, safe and easy to use drill completely eliminates the risk for its operator from vibration white finger and hand-arm vibration associated with conventional hand held percussive drills. Diamanttek’s drill operator can use the 20 UTL
rig throughout an entire 8 hour shift without stopping, unlike a normal hand held drill where the operator would have to stop after an hour. “The E-Z Drill is very good as our drill opera-tor is not holding the drill when it’s drilling, so there is no transfer of vibration, unlike normal hand held drills,” says Diamanttek operations manager Chris Holloway, who has over 25 years experience in the drilling, sawing and demolition industry.
480 holes a day!The 20 UTL is part of the leading American automatic drilling system manufacturer’s exten-sive range of equipment available exclusively in Europe through concessionaire Castellan. The 20 UTL uses the standard E-Z Drill variable feed system comprising a CP32A rock drill mounted in a carriage, which is moved in and out by an air cylinder controlled by a joystick. The equipment is supported in a simple frame with two pneumatic tyred wheels allowing the operator to quickly and easily move, reposition and accurately align the drill for the next hole. This enables remotely controlled drilling with minimum hand and arm vibration exposure for the operator. A single tool compressor powers all the functions of the E-Z Drill rig.
Independent test for K 750 power cutterAn independent study by Chalmers University of Technology in Sweden has confirmed that the Husqvarna K 750 power cutter has an exceptional ergonomic design. The relationship between its centre of gravity, its handles and the cutting point makes it easier to handle and requires less force for both vertical and horizontal cutting.
“Husqvarna has a long tradition of developing products with a strong user focus. We have been doing this ever since our first hand-held chain saws and clearing saws were introduced in the 1950s. When the first power cutters were launched, it was natural to integrate the same ergonomic ideas into their design too. We’ve known for a long time that our machines are ergonomic, but it’s really good to have it in black and white”, says Husqvarna Con-struction Products Power Cutters Product Manager Håkan Aldén. “Our customers increasingly appreci-ate ergonomics and user-friendliness. They see that
a machine that is so simple and conven ien t to hand le no t on l y bene f i t s the user, but a lso m e a n s
more efficient cutting. The new, more rigorous EU rules, for instance with
regard to vibrations, are clearly driving developments towards more ergonomic machines.”
Chalmers examined how much force is needed to exert a pressure of 100 kiloponds. It turns out that a machine whose front handle and centre of gravity are positioned close to
the cutting point, as in the Husqvarna K 750, needs less muscle power to reach this pressure than machines whose handle and centre of
gravity are further from the cutting point.“The essential point is to
minimize the force needed to control the machine during operation,” says Håkan Aldén. “This makes it easier to work
with, the user does not get tired
so easily and the risk of accidents is reduced. Ultimately, the job can be done more quickly and with higher quality.”

Demolition in UAE
LODAB Demolition AB, with its captain Lars-Olof Dahl steering the company, continues to surprise and is strengthening the Swedish demolition company’s position as one of the world’s 100 biggest demolition contractors. “We have had some very good years, but of course the ongoing recession has also affected us. But when it struck the management sat down and discussed how we should react to the situation. We decided it was full speed ahead as we believed that accelerating through the crises would give us a better position when we eventually come out of it,” says LODAB owner and president Lars-Olof Dahl.
Complex Missions
LODAB Demolition AB was formed in 1996 and Lars-Olof Dahl, who had previously worked for several other demolition companies, invested in a used Brokk demoli-tion robot and started to take on small jobs. Lars-Olof is skilled at finding unconventional demolition solutions, which he has been benefiting from over the years and led
to a number of big and complex demolition contracts. Now LODAB Demolition AB has 45 employees and a turn over of EUR18,5M. From starting out as a traditional demolition contractor of household and industrial buildings the company has developed into a specialist contractor for the demolition of complex structures, often where extremely heavy equipment is needed.
Most of the jobs are in various types of process industries like paper mills, steel plants and power sta-tions, as well as different types of bridge demolition projects. All jobs are different and more a rule than an exception that special demolition methods and tailor made demolition attachments are used on its demoli-tion projects.
New office in Stockholm
The home market for LODAB is still Sweden and the headquarters is in Örebro, about 200km west of the cap-ital Stockholm. The company has also recently acquired
a new office with a large workshop in Stockholm. This year has been difficult for many Swedish
demolition contractors and a lot of projects have been delayed and many put on hold until the recession is over. LODAB has also lost projects and some have been postponed. But several large contracts have been won and Lars-Olof Dahl estimates that they will reach about the same turn over for 2009 as in 2008.
“During the spring we won a number of really large demolition and recycling projects, which will keep us busy for quite a while. In the Stockholm area though, which has been our bread and butter, things are much quieter now. But we hope the situation will improve during next year,” says Lars-Olof.
Despite the recession the company continues to expand and purchase new equipment. LODAB has also formed a new company LODAB Sanering that will focus on the clearance of hazardous materials like PCBs, asbestos, oil, heavy metals and environmental remediation. The company has taken on 10 employees
LODAB, founded and owned by Lars-Olof Dahl, has during a bit more then a decennium become Sweden’s biggest demolition contractor and one of the 100 biggest in the world. The company has today operations both in Sweden and abroad.
When large and complex structures are demolished in Sweden often the name LODAB is on the excavators. Most of the projects are paper mills, steel plants, power stations, silos and large terminal buildings containing reinforced concrete and steel. For the past two years LODAB has also been operating in the United Arab Emirates.

Demolition in UAE
bringing the group total to 55 people.
Wide range of machineryLODAB’s machine and tool fleet is continuously renewed and the company currently has 16 demolition excavators from 7.5 to 140t with all the necessary hydraulic and me-chanical tools and attachments weighing up to 23t. These include nine scrap shears, 10 pulverisers, 10 hydraulic breakers and about the same number of demolition and sorting grapples. In addition LODAB also has a number of Brokk machines, a big number of Bobcats, three large Liebherr cranes, mobile recycling crushers and screeners, a wind screener and a number of wheel loaders. For the clearance services they have suction containers and a vacuum suction device mounted on a truck.
Two Komatsu PC228 excavators equipped with quick couplers have also been purchased recently from Oil Quick, together with a number of tools for scrap handling and a special screener for recycling light de-molition material.
LODAB is certified according to the Swedish quality system BF9K and is a member of the Swedish Demolition Association as well as the Swedish Construction Federa-tion. The company has the necessary requirements to carry out the services they offer and the staff is regularly updated with new regulations.
Big Missions in Sweden and Abroad
Although its main market is Sweden LODAB has taken on jobs abroad and these included two projects in Dubai and Al Ain. Both projects were for the demolition of reinforced concrete and steel bridges for the consortium BESIX, comprising the Belgium based company Sixt and the Dubai company Belhasa. The project in Dubai was for the demolition of the Al Garhoud Bridge. It was a difficult job and the necessary special demolition expertise was not available in the region.
“The special knowledge and equipment to demolish a bridge like the Al Garhoud wasn’t available among local demolition contractors. When I say special knowledge I
mean theoretical and practical knowledge and the nec-essary machinery and tools to bring down the structure within a tight programme. In addition the job needed to be done with the highest safety precautions and with as little disturbance as possible on the environment around the site,” says Lars-Olof Dahl.
There is a lot of competition on smaller and less complicated projects from contractors from India or Paki-stan, Russia, Turkey, Italy, UK and The Netherlands.
“We can’t compete on the smaller and easier jobs as our salary levels are so much higher for our men. But we can compete on very qualified jobs where special machinery is needed and where efficiency is paramount. So it is cost effective to put our equipment on a ship all the way from Sweden,” says Lars-Olof. “We have a good position in the United Arab Emirates and are fast and pull down structures safely.”
LODAB started demolition of Al Garhoud Bridge early in 2008 and project manager was Mika Myntti, who has several decades of experience from working

with construction and demolition of steel plants in the Arab world.
The Al Garhoud BridgeThe first task was to demolish the 450m long Al Garhoud Bridge in Dubai. It took 10 weeks to demolish the 160 m wide, eight-lane bridge, including the foundations in the water, which were removed to 1m below riverbed level. The bridge was made of reinforced concrete beams resting on four concrete foundations, each containing 30 steel pillars filled with concrete. Machines and tools used for the job were a Hitachi 650 and a Hitachi 850, one with an extended stick of 5.5 m. These were complemented by two 5t Furukawa F70 breakers a concrete crusher from Trevi Benne. A big part of the demolition and earth removal was made from a barge.
“The breaking, cutting and removal of earth and stones where quite difficult. The barge was 2m high and we had to reach to 1m under the bottom level. We also had to keep track of the tide in order to reach to the bottom,” says Lars-Olof.
LODAB’s team of eight people and two superin-tendents demolished about 1500m3 of concrete and
other types of material in 10 weeks in unusual conditions. “When we started in January 2008 the climate was good, but by the end of the project we had some days with tem-peratures as high as 48° C. That was pretty hot but we got use to it. Our machines are also well air conditioned so the operators didn’t complain. I was a bit worried about the machines and tools overheating,” says Lars-Olof.
In terms of temperatures things got different when LODAB was hired to demolish a pre-stressed concrete bridge in the desert city Al Ain.
Al Ain in the desertAbout 150 km south of Dubai, close to the boarder of Oman is the Emirate Al Ain where temperatures often reach over 50°C in the shade. It is impossible to work outdoors in the middle of the day.
In the centre of the city a pre-stressed concrete bridge had to be replaced by a crossroad. The same machinery was used at this site plus the pulverizer HC60 from Trevi Benne and the large FX-90 concrete crusher from NPK. LODAB had three employees on the job and one superintendent. About 4,000m3 concrete was demolished and the work took about 12 weeks.
It is not unusual for demolition contractors to cross over boarders, but to go from Sweden to UAE is uncom-mon. The reason for this is the ability to offer different expertise not available from other contractors in the area, according to Dahl. But special competence costs money and something they have in UAE.
“We make money on what we are doing, no doubt. Otherwise we wouldn’t take a lot of equipment so far which cost around EUR12,000 in freight just one-way per excavator,” adds Dahl.
But LODAB has gone to the UAE to stay. They have
a lot of interesting jobs that LODAB is ready to take on whenever they are needed as they have their company in Dubai. However, the UAE is suffering from the economic situation just as much as any other country in the world and many projects are on hold.
Back to the old country
Some of LODAB’s machines are still in UAE but will be sent home, as they are needed in Sweden for a number of process industry projects. The demolition of a large paper mill at Vargön about 150 km north east of Gothenburg started recently. This is a big job that will take up to a year to finish and around 100,000 t of concrete and steel will be demolished. LODAB has recently finished a number of other jobs, including the demolition of another paper mill in mid Sweden, a steelworks in Degerfors and the demolition of the railway terminal Klara in the middle of Stockholm.

The UK concrete cutting contractors Robore Cuts were called in to carry out the concrete cutting aspect of a Marble Arch subway project.
The Marble Arch had a Four subway under-neath it, with four entries, one on each side of the Arch. These had to be filled in, due to the potential terrorist threat of placing explosives under the Arch. Robore’s task was to level off the subway entrances, by cutting the retaining walls down.
Heavy flintAs with most concrete structures in London, the aggregate in the walls was Flint. This aggregate is the hardest in Europe, over twice as hard to cut, and twice as demanding on the life of diamond consumables as any other aggregate.
Added to this, there was the usual steel re-enforcing bars throughout the cuts. Approximately 180 m of sawing at 350 mm deep was needed to level all of the subway entrances.
AERO® Matrix bladesRobore Cuts insist on only the best diamond tools for there operators, maximising ef-ficiency on the job. They choose the market leading blades, according to manufacturer Diaquip Concrete Cutting Solutions, with positioned diamonds, and one of the new Aero® Matrix Positioned Diamond Wall Saw Blades. This is a new model on trial from specialist concrete cutting equipment suppliers Diaquip.
It was soon evident that the Aero® Matrix was performing signifi-
Marble Arch subway concrete cutting project
cantly better as the cutting progressed. This is down to the fact that the Aero® Matrix blades have the diamond positioned in a honeycomb effect, as opposed to rows, ensuring there is more efficient use of the diamond on the surface of the
cut at all times.
