From demolitionto deconstruction

My facial expression was one of surprise and astonishment when I was first introduced to the word deconstruction (Rueckbau in Ger-man). I am rather critical about the inclusion of newly minted words into the common usage. I was af-raid that the esoteric trend in the language had finally arrived at the construction site. Which begs the question: why does every new word coined need to have a positi-ve spin?

When, a bit later, I visited a de-molition site I quickly understood why this new word was coined. I watched the demolition excavator at work. The very skilled opera-tor dissected the old house into its parts with surgical precision. All the construction rubble at the site was sorted exactly and carefully deposited into separate bins for iron, stone, wood and concrete.

Construction sites with buildings undergoing demolition are always fascinating to watch and it is not a surprise to find a crowd of onlookers. It is therefore not surprising that mo-dels of demolition excavators rank high in popularity with collectors. The newest examples of this genre are the two Hitachi ZX 1000K vari-ants introduced in this volume.

Demolition is the mainstay for the Munich firm of Luff. They are a well-known entity for dragline excavator enthusiasts. The vene-rable Menck dragline excavators are still in use by this firm around town at their demolition sites. Not for fun, but for profit and because they are best suited for the job at hand! Peter Veicht, model making artist par excellence, can often be found at these sites, watching the machines at their labours. We are introducing him and some of his outstanding models in this issue.

From Munich to Lucerne, from Menck to Ruston-Bucyrus: Model maker Herbert Manfurt, known from his 10-RB and 30-RB mo-dels, lets us look over his shoulder while soldering. He ponders why so many modellers are afraid to use this basic technique. To take the mystery out of the art of soldering he shows us how easy it is once a few ground rules are followed.

With this issue I hope that I can once more introduce all readers to a broad spectrum of the hobby.

Happy reading and have fun.

Norscot 1:50

A high grade of functionality is one of the features of the new as-phalt pavers. Moveable hopper walls, an attachable wooden beam for lifting and enlarging. There are moveable steps as well as a stee-rable front axle on this nicely de-tailed model. There is also a pro-tective roof for the drive unit and several wooden planks that can be added to the model.

Universal Hobbies 1: 50

The long awaited model of the Komatsu HM250 fulfills all the collectors’ wishes. All major parts are made from metal without com-promising on details. Except for the fixed mounted rear axles full functionality is guaranteed. A great addition to any articulated dump truck fleet. The PC200-8 Hybrid released is a re-lettered model of the existing PC210.

Conrad 1: 50

Exhibition and summer new re-leases are enriching the Conrad program: The Mercedes Actros appears as a four axle truck with three side tipping body by Dautel in a silver paint scheme, as a three axled version with a tandem dump trailer by Meiller in the paint sche-me Eurovia and as all wheel dump truck with loading crane in bright yellow. The fleet of THW (Tech-nisches Hilfswerk) is augmented with the Mecalac 8MCR tracked excavator with bucket scoop, back

hoe and pallet fork accessories which is joined by a Man TGS M4x4 as three side dump truck with loading crane for the THW fleet. Small detail parts such as mirrors and antennas, to be added by the collector, are now made from a soft plastic material and so are less prone to being broken off accidentally. This is a real sign of progress for the modeller.

First Gear/ ACMOC 1: 25

The Cat DW20 has appeared in a super detailed version by First Gear available exclusively from ACMOC. So as to avoid putting too much strain on the hobby bud-get, it has been announced that the matching Cat 456 scraper will be offered at a later date. The DW20 rounds off the series of D9 models in the same scale.

Viessman 1: 87

For the series: “Models in mo-tion” an old favourite model has been resurrected. It is the Mercedes concrete mixer truck from the Kib-ri range this time as a ready to run model with its mixing bowl full of electronic wizardry that makes the drum turn. An electric winch desi-gned to be mounted on a wall can be operated with a digital or analog controller. The maximum length of rope is 80 mm.

NZG 1:50

Following the general purpose version of the Liebherr R944 Lit-

ronic, the scooping excavation bu-cket is now available. It is painted in the colors of the Australian firm, Mt Arthur Coal. That there are some disputes concerning color va-riations is understandable. It is our opinion that the simple blue and white color scheme of the mining excavator is simply outstanding.

Herpa 1:87

The Volvo FH3 with the Globe-trotter XL cabin was introduced at the toy fair as a mould for casting. It is now being offered in the Jens Thomsen version as a two-axled tractor unit with box trailer. The new truck is very nicely modeled. The engraving for the model is very precise, so that the separate-ly moulded and attached radiator grill, head lights and roof lights made from a translucent plastic material fit extremely well. Below the tilt able driver’s cabin one can spy a mock-up of the six cylinder Volvo diesel engine. The model has the new two part rims. The paint job and the lettering are faultless.

Wiking 1: 87

Wiking has brought out a set of three Magirus front wheel drive trucks in their theme series made from their old moulds. All are usa-ble for construction site modeling. They are: The 135D 11FS with loa-ding crane and a load of steel pro-files, the 235D 22FS with a load of concrete pipes and the 230D 22FK as a three-axled dump truck.

Siku 1:87 / 1:50

First up, In 1:87th scale is a concrete truck mixer from Scania

New on the market


with high play value. It is possible to extend the chute and to tilt the mixing drum. The New Holland T7070 is a new tractor for the half pipe dump trailer with dolly.

There are new tractors for the dumping trailer in 1:50 scale as well, consisting of the John Deere 8430 and Massey Ferguson MF 8690 in their bargain line.

Herpa 1: 87

The Nooteboom Pendulum-X with the new two axled Interdol-


lies is already available in two ver-sions: with an Actros tractor in a neutral red color and with the new Volvo cab in the yellow paint sche-me of the firm Hermann. The five-axled and double telescoping semi-deep well trailer from Goldhofer is paired with the three-axled Actros tractor unit in Green for Kűbler and in yellow for the firm of Hack. The Nooteboom Teletrailer appears in a new color variety for the Lam-merts with a load of two lattice masts and as an oversize concrete casting transporter in bright red for

the firm Seubert. In the green and silver paint scheme for the firm of Trost there are The MAN TGS four wheeled dump truck with the Goldhofer TU4 lowboy trailer. For the in house construction firm, the fleet has been augmented by the Actros M 08 on the new all wheel drive chassis.

by Albert Schmid

The “Jumbo-Drill” rig, weig-hing up to 22t was built by the

Finnish builder in the mid 80’s. The Tamrock factory is situated in the vicinity of the city of Tempere in Finland. It has a six cylinder Deutz Diesel Engine as a power plant that supplies 100 HP for the propulsion system. After the deployment and rigging at the work site at the tun-nel face all power requirements are delivered from an electro hydraulic system for the articulated and all-wheel drive unit. The power con-nections to the unit are made with cables and other supply lines that are mounted on drums at the rear of the rig. The rig is then supplied with its power and hydraulic and rinsing fluids from these connections.

There are two telescoping lift arms that are movable in all di-rections mounted on carriages and equipped with hydraulic hammer drills. A movable platform for mi-ners is attached on another lift arm. Depending on the diameter of the

shaft, up to 100 holes with a depth of 3m are drilled. According to the drilling diagram, they are then loa-ded with explosives and detonated in an exactly choreographed (de-layed) sequence.

The Finns ordered a model by Conrad in 1:50 scale similarly exact and limited to a run of 500 pieces. The very limited models were issued without type numbe-ring and were made exclusively for Tamrock and so never entered the dealer networks. Despite this, interestingly enough under the mo-del # 2501, they are listed in the Conrad II catalogue. Especially worth mentioning on the model are the two steering cylinders for the articulation and the very delicately executed control levers in the roo-fed control seat area. By the way, at the end of 1997, Tamrock was absorbed into the Finnish Sandvik conglomerate. Sandvik has been especially nice to collectors by releasing a great many exciting drilling, cutting and general below ground machinery models.

Eye Candy

from easily accessible construction sites and

rock HS 205 drilling rig is one of these special

machines



tried until the green and yellow color scheme was finalized. After a close friend, printer by trade, managed to print a good quality picture of the logo of the fictitious firm on a decal film the fun began.

Today, he is no longer sure if the color scheme is a total invention or if some transport firm in the Ticino region of Switzerland actually had vehicles painted in those or similar colors. At the same time, fan Mau-ro Zecchetto and a like minded friend, hunted and photographed the great variety of Saurer trucks then in use all across Switzerland.

Emergency vehiclesand escort duty

Zecchetto’s interest in emergen-cy vehicles grew due to a change in his occupation: he became a traffic police officer. Not only po-lice vehicles but also ambulances and fire engines drew his attention. At the time the services were still combined. The collected vehicles were altered to match the existing

prototypes exactly.There are several other connec-

tions between real life and hobby. He worked on truck inspection stop duty at heavy traffic sites and did escort duty with heavy and oversized load road transports. “For these I sometime volunteer and try to jump the queue, if I can”, he confesses. Due to the involve-ment with heavy duty transports, the focus of his collection has shif-ted to this, the third segment of his collecting hobby.

In the mean time, Mauro Zec-chetto has advanced to an expert le-vel in securing heavy duty loads at the police force. This also translates into to his hobby were all loads are expertly and prototypically secured down to the last detail.

Exclusively alteredmodels are in the collection

The collector explains that all models in his collection cases have been altered or improved on if only with a touch of a brush. The first

by Daniel Wietlisbach

The fictitious transport and heavy duty firm of Zecchetto,

began twenty-five years ago, has many of the almost indestructible Saurer trucks in its large vehicle pool. It is no secret that the owner of the firm is an ardent fan of the former Swiss truck maker. It is due to dedicated fans like him that we still can see Saurer trucks, main-tained in impeccable condition, on the road in daily use.

The 1:87th scale model coll-ection can be admired in Mauro Zecchetto’s display cases. The first model of a Saurer D290/D330 by Roskopf, a four axled version with a refrigerated box labelled for the brewery of Feldschlösschen (Ca-talogue # 401) appeared a quarter century ago. At that time it was the first model of a Swiss truck and a sensation for the model builders of the small country. It was the impe-tus to the collection featured in this issue. As an adjunct to the existing model railway, the Saurer truck fleet soon outgrew the rail road and became a hobby in itself.

Right from the beginning, Zec-chetto kit bashed, detailed or alte-red the models and the idea of an “in house” truck and heavy duty transport firm was born. The small scale firm needed its own paint scheme. Many different color combinations were considered and



re-paint jobs were handled with paint spray cans; today he uses a sophisticated and professional air-brush set up.

In the beginning, besides the Saurer models with all the possible color and chassis variations, truck kits from Kibri were much in de-mand for kit bashing purposes. To-day, it is the truck model line from Herpa that is favoured for its ver-satility. These models are easy to disassemble and the availability of spare parts such as driver’s cabins, chassis, tires, rims and other parts make it an optimal beginning for new conversion projects. The plain white driver’s cabins of the unde-corated sets are ideal candidates for custom paint jobs.

The raw materials for his pro-jects come from trade and hobby shows like the ones in Radofzell and Friedrichshafen. There he so-metimes is very fortunate and finds exclusive models that are not found

on the collector’s lists. Mauro Zec-chetto does not collect models to show off rarities; his aim is that he must like all the models and they must fit into his collection. Now and then he sells the most sought after models he has such as a Sau-rer truck model of a fire department water tender (435) painted in a sand color for use in the Arabian Desert and produced in a very limited se-ries. He purchases new arrivals as soon as they arrive on the dealers’ shelves. Too many times in the past he has missed out on items that were thought to be available for an extended time but suddenly disap-peared from the market.

He is unable to answer with cer-tainty the question about his favou-rite model. It changes with what is currently available. At the moment it is the MAN TGX in the fantas-tic paint scheme of the transporta-tion firm Zűrcher made by Herpa (156479) already altered and super

detailed with scale diamond tread on the steps and loaded with a lar-ge crate. He is also partial to his la-test Saurer kit bash, a chassis top-ped with a concrete mixer platform and painted in his house colors.

There are about 400 models on display at this time in his coll-ection: Saurer trucks and heavy duty transport truck and trailer units comprise three quarters of the total. There are a further 350 models that are waiting for alte-ration and detailing or repainting. There is enough work and fun to last at least a few more years. The next acquisition is a Universal fire truck by EADS (Herpa 48705) and of course the Liebherr R954 in the firm of Zűrcher Transport paint scheme is on the drawing board. The 1:87 scale will remain his main focus, says the collector, although he concedes that he likes many of the 1: 50 scale models.

His alterations to off the shelf models are many: rubber moul-dings around windows are high-lighted, rear view mirrors painted with silver color, lights are added, signs and number plates and ho-ses, diamond tread foot plates and many more details are added.

For alterations of heavy duty transport trucks and trailers he uses the excellent diamond tread pro-ducts from Friho (www.friho.ch). Special decals are custom made for him in Dresden by DecalPrint (www.decalprint.de) .

The collector

Mauro Zecchetto, 49, originally apprenticed as a locksmith but became an electrician during the crisis of the mid-80’s. Then, at the age of 26, he changed direction once again and entered the police force. For a few years now he has been employed as a traffic inst-ructor in schools and kindergartens and the remainder of the time he does duty as a traffic police officer.

Besides his model truck collection hobby, he still finds time to work on his model train layout, is active in sports and hiking and the Fasnacht (Swiss Carnival) organization. In his holidays he likes to drive a Saurer truck that belongs to a friend who owns a transporta-tion business. He is also engaged in committee work for organizing the meeting of Swiss Commercial Trucks (Treffen Schweizerischer Nutzfahrzeuge) in Thayingen. This meet that occurs every two ye-ars exhibits up to a hundred trucks. The next meet is scheduled for June 2011.

Mario Zecchetto is married with two children and lives in Stetten, Canton Schaffhausen Switzerland.

him and also admire his super de-tailed models may call him a bit of a nutter, but this does not faze him. He enjoys his hobby despite the detractors.

About ten years ago a colleague designed a website for him to make

his collection accessible to a larger audience. From this several useful contacts developed and led to an exchange of information between enthusiasts. Today he is the web-master of his own site at www.zeggi-modelbau.ch.

Having a great working rela-tionship with MAN Switzerland has led to commissions for special paint jobs for scale models. MAN clients request them for special oc-casions like firm jubilees or anni-versaries.



Often, the design of a new con-struction machine undergoes

changes during the development phase and this was indeed the case for the TA 230. Conrad launched a new, upgraded model incorpo-rating the design changes into the previously released model. The many changes in detailing include, among other minor ones, the shape and color of the radiator hood and grill. We like both versions of the prototype: perhaps this could be a real milestone in the model release history of the firm. Conrad’s high adherence to detail and functiona-lity, and the fact that the models are “Made in Germany” are unique in the trade. The casting for the un-conventional design of the driver’s cabin has been carried out success-fully. Situated on the front part of the machine, it looks a little out of scale compared with the dumping bin but when checking the measu-rements taken from the prototype against the model, it is found to be correct to scale. The weight of the model indicates that, as usual, the main components of the model have been made by die casting.

Front unit

The front part of the unit sits on a tensioned axle assembly imitating the pneumatic cushioning. It has accurately moulded tread pattern

rubber tires. The engine compart-ment and the cabin are metal cas-tings, but the engine hood is a se-parate plastic casting. The radiator area is where the main difference to the previous model is most nota-ble. When the first released model had ventilation louvers on the front of the radiator, the new release does have the above mentioned fine grill. But the white paint used on the front unit and cab there has been extended forward to cover the engine compartment, but not including the radiator grill. This gi-ves the illusion of a narrower front unit. To achieve the change the existing casting for the front had to be altered.

The air intake vents on both si-des of the engine compartment are made from a very fine plastic casting to copy the prototype. The window glass in the driver’s cabin is moulded in one piece and the window wipers and the window support struts are printed on exact-ly to size. This is a great solution and has possibilities to be applied on other modern prototype machi-ne models in the future.

As previously mentioned, the model has a great variety of de-tails. The etched headlight protec-tion cages are outstanding and so is the protective mesh screen over the back window and the perfora-ted cooling jacket over the exhaust pipe. Beside the exhaust on the mo-del there is a dump security support painted in brilliant red color. The lowest rung on the cab ladder is made from a soft, flexible plastic casting and is extremely fine. This part is also mounted to be flexible on the prototype in order to pre-vent it from being bent out of shape when the unit is in action.

Both amber warning beacons have rotor simulators on the inside of the lights, a very well obser-ved and realized detail. Rear view mirrors and two hand rails out of a soft plastic material and metal hand grips have to be added by the collector.

Rear part of the unit

The connection to the rear part of the unit has, besides the two hydraulic cylinders for the articu-

lation control, four hydraulic lines and five separate supply lines for heating the hauling bin. The three hollow rivets on the joint and cy-linders look a bit old-fashioned and would almost disappear with a drop of matching grey paint.

The four wheels of the rear unit are of the same quality as the front ones. It is the suspension arran-

gement that is special. Both rear axles have self-locking transverse differentials and, like the prototy-pe, adapt to the uneven ground.

The hauler’s bin can be lifted to the prototypical height for dum-ping, shown on this model is the pivoting tailgate which is an option on the TA230. The tailgate opens and closes without any problems

or hesitations and is connected to the chassis with two plastic bands, just like on the prototype.

As per usual, the paint job and the lettering are first class and crisp. In closing, whether the hauler is a great success or not for Liebherr, the model of the TA230 by Conrad certainly is.



by Urs Peyer

Strict safety and disposal regu-lations forced the industry to

change from wholesale destruction to a selective deconstruction pro-cess. The era of radical demoliti-on had come to an end for good. Now all waste had to be sorted into burnable, stone and old iron and re-cycled if possible or properly disposed of. The advent of the first concrete sheers as attachments for hydraulic excavators helped in fa-cilitating the new work processes.

Japanese Pioneers

Specialized long booms and jibs and scrap metal cutters or concrete sheers enable hydraulic excavators to be used in large factory hall set-tings that have high ceilings and were formerly out of reach to re-gular excavators. The Dutch firm of Verachtert was one of the ear-liest companies to offer long reach booms which were constructed using a long straight boom, a short connecting piece and a long jib.

The real pioneers in Super Long Boom manufacturing were the Japanese. In 1981 the firm of Ko-belco developed a hydraulic demo-lition excavator for the Japanese market. This machine had a maxi-mum height reach of 40 m. By the end of the 80’s Komatsu delivered the first PC400 LC Excavator with a special demolition attachment to the European market. The attach-

ment, weighing in at 11 tons, was in three parts consisting of a 12 m boom, a 2 m connecting piece and a 8 m jib. The 46 ton hydraulic excavator could reach a working height of 22 m.

In 1994 Komatsu followed up with the PC650-5, the world’s first demolition hydraulic excavator to reach an amazing working height of 40 m. With its 90 ton weight it was the largest demolition excavator in Europe. The firm of Kobelco sold its first SK 1600D in the summer of 2002. It had a four part boom/jib as-sembly and could reach a height of 51 m. A set of heavy duty demoliti-on scissors weighing 2.9 tons gave the necessary “bite” to the unit.

The even larger SK3500D can ex-tend its four part arm assembly to height of 65 m. For transportation purposes, the arm and attachments can be disassembled into 17 parts. The 328 ton excavator has no pro-blem demolishing 21 storey high buildings. For the deconstruction of factories an optional 20 ton pulveri-zation attachment is available. The working height with this attachment is still an impressive 32 m.

Boom in EuropeAll major European manufactur-

ers now offer well defined demoliti-on excavator programs. How big the demand in that sector is was seen at the recent Bauma exposition. Not fewer than nine new or reconfigured models were on offer. The “smal-lest” on offer reaches a working height of 17–20 m and weighs bet-ween 40 and 45 tons. On the oppo-site end of the spectrum are the large excavators like the 132 ton Liebherr R984C with a maximum working height of 41 m and a carrying capa-city of 2.5 tons. The 108 ton machi-ne from Hitachi ZX807CH-3 can be upgraded to reach a height of 40 m. The largest demolition excavator in service at this time in Europe is the 220 ton Liebherr R984C with a te-lescoping boom. It can reach a wor-king height of 65 m. The monster demolition excavator is a cooperati-ve effort of Liebherr and Kocureck. The maximum reach on this unit, riding on a Caterpillar 5110B un-dercarriage, is an astounding 90 m. However, the unit has been out of service for the last year because of some technical problems.

Excavators used for demolition work

Demolition expertsIn the past, demolition of buildings was

handled with the much feared demolition ball.

But, beginning at the end of the 70’s, a slow

and sometimes legislated change in practices

has taken place.




Many collectors ask if the ma-chines that are on the mar-

ket in the far east under the ZX 1000K label are the same as the Hitachi model ZX870LCH marke-ted in Europe. The basic machines are the same; however they differ in many details. This is especially so for the two demolition versions realised as models by Ken Kraft, a bold initiative by the Japanese dea-ler and shown here.

Undercarriage

The very well proportioned mo-dels look great and to scale at first glance. This is confirmed when the measurements of the model are compared to the prototype. The width of the undercarriage with a scale 4100 mm width and 650 mm floor plates is correct for the basic ZX 1000K, but for the de-molition version the width should be 4600mm. This leads to specu-lation that the basic model will be released later on in the plain exca-vator version; at least this could be an explanation for the deviance.

Both drives have the prototypical three support bearing wheels and nine running wheels. These are all movable, although the lower run-ning wheels are not visible since they are covered by the wheel cover apron. The tracks are made

up of 43 links (compared to 51 on the prototype) and are kept in po-sition using a spring. Unfortuna-tely, the springing is so tight that is difficult to make the tracks turn. A reader, Jean-Pierre Burget, uses the spare links included with every NZG model and inserts them into the tracks. This reduces the tensi-on considerably. This is relatively easy to do as the links are only loo-sely joined together.

To transport the prototype both tracks have to be taken off the ma-chine and for this there are four support struts mounted on the X frame on which the upper carria-ge can rest. The supports can also be found on the model and can be folded out and can be unscrewed. The two track units can be remo-ved first by loosening two screws.

Hitachi ZX 1000K by NZG in 1: 50 scale

impressive versions. They are demolition ex-

tively and are equipped with oversized con-

crete shears.

with them with great success. The door on the left side to the mainte-nance walkway for the engine and hydraulic rooms can be opened. On the prototype the engine room houses a water cooled four stroke Isuzu AH-6WG1XYSA-03 engine built to the newest environmental and noise protocols. It delivers 397 kW (540 hp).

On the right hand side are two large radiator grilles one for the radiator itself and the other one for the oil cooler. The most visible difference from the ZX 870LCH models is found in the counter weights. These weights are made from four parts and not a single so-lid part, and are mounted in a frame that can be lifted; this is shown on the model as well.

The cabin has interior detailing and a perfectly fitting window cas-ting with partially cast and printed-on window struts. There are two protective cages mounted on the cab above and in front as when in demolition use. Unfortunate-ly, the cabin is fixed and cannot



be inclined forward. All handrails are mounted freestanding and are made from metal. Mirrors, air in-takes, fuel lids and exhaust (hollo-wed out!) round off the details on the upper part of the model. Also worth mentioning is the fact that all running boards and steps have been painted in a matt black color tone.

Equipment

Jib and boom of the prototype are designed in kit form. This al-lows the machine to be equipped with the right combinations to reach the desired building height. At the same time it greatly simp-lifies the transportation of the unit. The combination of various parts makes it possible to reach heights

of 12, 18, and 30 up to a maximum of 40 m. NZG has modeled the boom and jib combo for 18 m and the very impressive 40 m combi-nation. Both jib and boom are very nicely detailed. The HRD version contains two 3.25 m extension pie-ces as separate parts; however they are permanently bolted together.

The hydraulic lines are mostly freestanding or part of the casting on the boom and jib, and as on the prototype, made from flexible rub-ber material. To attach the boom two bolts are required and for the hydraulic lines there are pre-drilled holes to attach those to the arm. The hydraulic cylinders are capa-ble of keeping the 18 m long boom extended in any position. The per-pendicular position is the only one possible for the 40 m boom. The

free standing display of the model in this mode is not recommended.

The two concrete shears are very well made and beautifully detailed. In the shorter configuration it is a model of the Okada TS-W2200W weighing almost 10 t and applying 210 t of pressure. The longer ver-sion has the Ohsumi FE500 weig-hing 2.3 t and applying a force of 69 t: the prototype is able to cut through steel.

The package containing both jib and boom combinations with the model is available exclusively in Japan. Coloring and lettering are faultless. The paint job covers the metal castings well but is not too thickly applied. The lettering is sharp and clear, and even the little yellow danger signs are not over-looked.

Models of construction ma-chines appeared at the same

time or shortly after the prototy-pes. The crude tin models without many details first appeared in the 1930s. Thirty years later this took an unexpected and dramatic turn.

Let us look back in time a bit. The first television broadcasts by ARD in Germany were in 1954, followed by the ZDF and the Third program chain. The daily paper was the main resource for the dai-ly news and advertisements. Many citizens had a motor bike instead of a car. To travel larger distances one took the train. Plane trips were reserved for the very wealthy.

To help selling a construction machine to a potential buyer a dif-ferent solution had to be found. After all it was clumsy and ex-pensive to lug a full-size machine around the country. This gave rise to the production of scale mo-dels, salesman’s samples, in the 1960’s. These, in 1:24 scale, fully functional and very detailed mo-dels could be carried by the sales rep in his sample case and used to underscore the impact of the sales prospectus handed out.

Since these models were heavy and robust, they were natural can-didates for the backyard sandbox. Toymakers jumped on the bandwa-gon and started to produce models to fill this market gap. After all,

Games in the sandThe history behind the appearance of Tin-pla-

what is more fun to build roads, ditches dams and mountains in the sand box?

This was the beginning of the epoch of toy construction ma-chinery, for example by Tonka. This firm is still producing a line of construction equipment today. Once made from Tin-plate, now they are made from a weather-re-sisting plastic material. This does not diminish the play value of the toy. With a lot of Brooommmm and Wroommmm sounds, there are countless cubic meters of sand being moved by the innumerable pint-sized operators in sand boxes around the globe.

Tadano Faun HK70 from WSI in 1:50 scale

New model highlight

by Carsten Bengs

As with previous models, the first test applied was to see

if the model rolled without any resistance. The model is easy go-ing and rolled without binding or locking on the desk surface. All axles of the Actros are steerable so that even very tight curves can be negotiated without a problem. The steering for the front two axles is connected with a coupling rod to the rear axle and the middle axles are designed as a bogie, and its side play is minimal. The fuel and air tanks as well as the main gear shaft are visible when looking at the propulsion system. The unique support system is remarkable. The support feet are movable, as on the LTM 1050, and can be shown in a transport or a work setting. The support arms are secured by a small bolt that is used to fix the supports in the desired configu-rations. The width of the truck is decreased when the support arms are folded back for the transporta-tion mode. The treads used to at-tach them are on the inside and not readily visible. As usual with truck mounted cranes the hydraulic cy-linder is mounted sideways on a support arm and WSI has applied a really sophisticated folding system in miniature. It seems hardly possi-ble to apply more detail.

Running boards on the chassis, handrails, mirrors and warning signs round off the highly detailed model. The crane mats included with the model are a nice touch. Imitations of small hoses are at-tached to the front supports. The roomy Actros cabin can be tilted forward to reveal the detailed en-gine compartment. A licence pla-te and a prototypical trailer hook round out the many details.

Upper Carriage

The upper carriage bears the signs of the highly developed en-graving craft from WSI. There are several hose imitations that run from the motor to the winch as well to the ballast attachment and turning mechanism. The winch can be operated by inserting the key that is provided. There are some very nice details to see back stage. The engine mock-up can be seen behind two hatches mounted on easily operated small hinges. It de-

picts the 90 kW Mercedes Motor of the prototype.

The counter balance (on the pro-totype this weighs 15.2 T) is com-prised of a base plate and four add on plates that are attached using plug in connections. This seems to be a better solution and gives bet-ter stability then the design used on the LTM 1050 model.

The cargo hook has twin sheaves and, as with the LTM 1050, a jib and cotter lock as a connector. The lifting rope is connected through the rope lock with a knot and at-tached to the head of the dolly with a small plastic bolt. To change the configuration, for example to re-rig for a lattice top attachment, it is very easy to release the rope and re-attach it.

Unfortunately the rope used on the HK70 is the typical rope made in China and is not twist free. This causes the hook to be turned around, a less than ideal situation because it does not look right. An extended report on twist free sca-

The Faun HK70 has arrived to match the LTM

1050. It is the newest creation of model ma-

ker WSI and seamlessly follows the previously

released LTM. First to the market, this crane is

mounted on a five axle Actros.



le rope will appear in a future re-port. Most of the rope sheaves on the model are single mouldings and move freely. Only on the top head sheave assembly is there a solid casting with six slots. Espe-cially here it would have been nice to install the single castings. The main cargo hook has two sheaves (not quite correct) for simple rope securing.

With the four telescoping boom pieces, a height at the top of the boom of 90 cm, or 44m in the pro-totype can be achieved. With the lattice jib, the height can be increa-sed to 1.2 m. The storage place for this lattice tip is very well execut-ed on this model. It can be secured with small bolts on the one side of the boom. New however on this model is the lower storage sup-

port arm for this jib. It is jointed and can be folded out to a length of 4 cm. The prototype requires this support arm to be able to mount the jib successfully.

In conclusion: With the release of the Faun HK70, WSI has set the standards higher again. It is a cra-ne model that pushes the borders of detailing and still offers great functionality.



by Robert Bretscher

The urge to build models for Pe-ter Veicht, trained as a vehicle

mechanic, started in his youngest years. He used Lego blocks to build his first excavator models. For inspiration he visited the many subway construction sites in Mu-nich. There, on the gravel heaps, he started to sketch and paint tech-nical pictures of excavators and cranes. A sales representative for the construction machinery firm Demag noticed the young artist and his work. He got his firm in-terested in the painter, especially promoting the realistic execution of the paintings. This motivated Veicht to paint further construction site pictures in Munich.

Very soon after, he built up the courage to create a historical drag line excavator model out of copper and brass in 1:50 scale. He used only the technical paintings he had produced earlier on when painting on the construction sites. It was the Menck Excavators, then still in use, that were the main inspiration for his first models. After some trial and error, the artisan metal worker finally achieved his goal to produce beautifully detailed and historically correct excavator models.

Models good enoughfor an exhibition

While reading the local paper one day, Peter Veicht learned that the German Museum was planning a model exhibition. He contacted the organizer and was able to get a formal invitation thus fulfilling his dream of exhibiting his models of historical excavators. After this first success followed exhibitions in co-operation with the U-Bahn Referat (a group handling the publicity for the building of the subway system in Munich) and for the “staedtischen Arbeitsgrup-pe fuer Planung” a city planning group culminating in an exhibiti-on at the subway station Ungerer Strasse where a huge 1: 50 scale construction site diorama was dis-played. The many excavators and

construction machines used in the display were absolutely amazing. The media and countless visitors admired this miniature construc-tion scene.

The majority of his models are in 1:50 scale and are fully functional. Excavators with lattice booms can be adapted into either backhoe or scooping bucket mode with mi-nimum effort. Additionally, all doors, windows, service hatches and lids can be opened and closed. This gives the models a very reali-stic look. It is almost unbelievable what simple and yet ingenious me-thods the builder has come up with to achieve these effects.

Walter Zacherle was a great pro-moter of Veicht Menck excavator models. He owned many historical drawings and pictures of Menck excavators. Further information

Peter Veicht Model builder and artist

The draglineexcavator historian

Peter Veicht is a well known name in many

respects and not only to collectors of drag-

line excavators. He is a highly skilled artist

and over the past 28 years has created many

exquisite models. So it is high time that we

introduce you to his work



and encouragement came from the drag line excavator enthusi-ast, Werner Luff, owner of a firm specializing in demolition work. Peter Veitch met him by chance on a construction site in Munich. Fascinated by the powerful Menck excavators on Luff’s construction sites, Peter Veicht was inspired to start a new series of models. It is amazing that all of Veitch’s ex-quisite models were created in a small, dark corner of a cellar in the building where he lives.

Not only Menck

It should be noted that all the models were initially made for his use only. However a few rare pie-ces from small series, manly drag-line excavators, have ended up in collector’s hands.

Besides Menck excavators Peter Veitch has also built construction machine models of Demag, We-serhuette, Gross, O&K as well as many American and English ma-nufactures. In 1990 Peter Veicht mastered the art of making metal castings. In a short time, master-fully crafted metal track links from the in-house production could be mounted on his models giving them an even better prototypical look.

Peter Veitch is a gifted artist creating realistic models as art ob-jects. These models are created by using only pictures or paintings, using no plans, and only the sim-plest of tools.

It is almost unbelievable that such magnificent relics of a bygone area, made to scale out of copper and brass, are made using only visual observations. For him his inspira-

tion and his free spirit are the sole motivation to tackle yet another art model. The lucky owners of models by Peter Veitch can confirm the ab-solute prototypical execution and adherence to detail that has made these excavator models, produced in very small series, famous.

Among his specialities is the alteration and super detailing of commercial scale models. The-se receive from Peter Veitch the “certain something” that seems to bring them to life.

Lessing, the German philoso-pher, wrote: The best way to praise the artist is when we forget to prai-se him after looking at his work (free translation).

Let us hope that we can hope to see many more exquisite dragline models out of the workshop of the master craftsman Peter Veitch.




Until now models of the 30-RB and 10-RB series have been

created by him. At the moment he is working on a series 71-RB. All of the 1:50 scale models are precision made down to the last detail. The models are complete with toolboxes, including con-tents, and fully functional. Brass and tin plate are the preferred buil-ding materials for Herbert Marfurt and all parts are soldered together on his models. He doesn’t know how many soldering joints it takes to build a model. ‘Perhaps it is in the thousands’, is the reply to our question put to the talented buil-der. That the joints stay together and never come undone, and he is utterly convinced on this point, can be only contributed to the ap-plication of the correct soldering technique.

Herbert Marfurt is glad to pass on his know-how about the art of soldering. There is no “wizardry” involved. To explain the technique step by step, the replacement of a set of handrails on a model of the Weserhuette W180 from NZG is chosen for demonstration purposes.

It really doesn’t need to be mo-dified, says the sometimes overly

modest builder on the phone, since the handrails are already quite nice as they come from the factory.

Indeed, the factory-supplied parts are fairly fine, but since the handrails have several bends in them they lend themselves perfect-ly as a demonstration, as they have a higher degree of difficulty.

Measuring and cutting

The problem with curved railings starts when they have to be measu-red, which is impossible with a ru-ler. The simple solution for this is Graph paper applied to the inside of the railings. It makes it possib-le to read the exact measurement, each square being one Millimetre. The “un-rolled” railing without its bends can then be built over the paper. One the paper is re-enforced

with heavy cardstock it can then be used as a soldering template.

Using the completed drawing on the graph paper, the brass wi-res can now be cut to length and the ends filed smooth. The up-per main railings and the two end posts are made in one piece from the same material and are bent to fit the drawing. The lower rungs of the railing are now cut to size to fit between the intermediary support posts and pre-placed over the dra-wings as shown. Since the applica-tion of solder to the wires can result in lengthening them a couple of 10ths of a millimetre, the wires are cut rather a bit short then too long. In order that the main part of the railing cannot move, it is attached to the drawing using Plasticine or a similar kneading compound. The wire size for hand rails and rai-

Liquid flux andsoldering wire

A secret tip among insiders in the collector

fraternity is Herbert Marfurt. He is a crafts-

tals. We had the privilege of looking over the

shoulder of the master builder.



lings in this scale is 0.8 Millimet-res diameter. The ideal material to be used would be brazing rods, but none, as far as we know, is availab-le in that small size. Unfortunately, the smallest one available is 1 Mil-limetre diameter.

Soldering withthe magic water.

There are two distinct periods in Herbert Marfurt’s work. The pre and post discovery of liquid flux! The whole secret of successful soldering is the use of liquid flux to prepare the wires for soldering. Compared to combined solder/flux combina-tions the separation of flux and sol-der is essential in achieving a clean and permanent bond. Working with compound solders lead to extensive post soldering work in cleaning up the joint by filing and sanding.

Herbert Marfurt uses the liquid flux and solders available from the firm of Hassler, in Liechtenstein. (www.hassler-profile.li)

Another important component in successful soldering is the use of a good soldering iron. He uses a 60 Watt iron, preferably a soldering station; this makes it possible to pre-set the temperature for the iron. In the case of soldering the railings, his experience has shown that a temperature of 400º C is ideal.

The actual soldering process is divided into four steps: First a drop of liquid flux is added to the piece to be soldered, the tip of the iron is then dipped into the liquid flux and lightly tinned. Too much solder on the tip makes for lot of clean up later. Then immediately the tip of the iron touches the two wires to be soldered together and the joint is complete.

The effect of dipping the tip of the soldering iron into the liquid flux is that the uptake of the solder is easier and it flows evenly. The wires which are to be soldered are held to the template with a finger. If a wire has been soldered in a wrong position, it can be re-positioned by quickly re-heating the wire and ca-refully moving it before the solder sets again. In such a case both ends of the wire have to be reset, to pre-vent over tensioning.

Less is more. This is especially so with soldering tin; better to add small amounts of solder a couple of times than in one big blob at once. If there is too much solder on the joint it can be removed after the joint is cold using a polishing disc on a hobby drill. It is advised to hold the finished railings between two fin-gers as to protect the other joints from becoming unsoldered because the polishing will create heat.

Bending and coloring

The last challenge in producing a beautiful set of railings is to create a clean bend and for this, a cylindrical object with the correct diameter has to be found. To achieve a perfect fit, a piece of tape should be glued to the cylinder with a horizontal line. The bending process can now begin and the railings are bent along the taped line, taking care not to bend the railing in one go, but to make the bend in several steps, always holding the railing so that the sol-dered joints are protected.

To clean the railing it can be sandblasted. A metal paint under-coat can be applied to make the paint adhere better. Airbrushing is the preferred paint method as the paint can be applied in much thin-ner coats.

Apprentice piece

The Norscot model of the Caterpillar 992G wheeled loader and the similar 854G wheeled dozer have handrails that measure 2.5 mm. This has led to the letting of a contract by Fredi Tschumi for the students of the Trades Association Centre for Learning in Thal Gäu Bipperamt (BLV) to craft metal replacement parts for the plastic parts of the model.

A report from Leandro Meister, 1st year apprentice for automatic work processes in manufacturing: «I approached the project from a few different angles and made some trial pieces. After a few tries and a conference with the instructors, we decided to use 1.6 mm welding wire. The bends required for the railing were made and the rest of the railing was assembled using the resistance soldering process. All soldering joints were filed smooth and then cleaned up further with a fine wire brush. The painting and installing of the finished products was handled by Fredi Tschumi.

The job required a lot of dexterity and patience and the work piece had extremely small measurement tolerances. Finally, I was very happy with the achieved result, and I hope, so was the customer.»

The anchoring of the

shoring wall is made

with horizontal moun-

ted girders and the an-

chors themselves.

by Daniel Wietlisbach.

In the original, the girders are made from two U-shaped pro-

files that are welded together with steel plates. The girders in the di-orama are made the same way but we use brass profiles that are sol-dered together (for measurements see the box below). The profiles are cut to length with a cutting disk in a hobby drill. Alternatively, with a bit more effort, they can be cut by hand with a metal saw. The cut surfaces are then cleaned up with a metal file. In order to solder the two profile pieces together, a pie-ce of scale wood is placed in the middle as a jig and the whole par-cel is held together in a small vise or a similar arrangement to prevent the parts from moving when being soldered.

It would be superfluous to exp-lain the art of soldering again. We refer to the article on soldering from previous pages in the maga-zine. Had the knowledge contained in the article from Herbert Marfurt

been available at the start of the project, some of the extensive and lengthy clean up filing could have been avoided. The main mistakes made were using a soldering iron with too low a voltage and using solder combined with flux instead of liquid flux, an error that resulted in too much solder being applied to the joint.

If clean up filing should be requi-red, then we recommend leaving the jig between the joint profiles to prevent them getting bent out of shape. A total of 15 girders were required for the anchoring of the wooden beam wall. Each girder had 6 to 10 soldering joints for a total of almost 120 joints.

The support beams for the side of the construction pit were much simpler to construct. The reason for this simplicity is that it is not possible to anchor the support wall to the basement of the house ad-joining the construction pit. Sub-stantial H-profile beams take over the support function in this part of the construction site. To ensu-re a perfect fit, they are cut a little oversized and then filed carefully to the correct length. When all the girders and cross braces have been soldered together and the profiles cut to length, they are immersed in a browning solution bath. This removes all the brassy shine and better prepares the surfaces for painting.

Connecting PlatesTo optimally anchor the wall, the

girders are welded to the vertically rammed in beams at a 15º angle. Steel plates cut in the appropriate angles are the connecting pieces between them. Since these are ba-rely visible in the model setting we can cut them from styrene strips. The angle is a given: the width at the bottom of the piece is 3.2 mm (1:87 2.0 mm) width on the top is 1.5 mm (0.5 mm) The connec-ting plates are now mounted at the same distance as the vertical be-ams. To achieve a super bonding action we use a combination of plastic and ACC (super glue). To soften the surface of the styrene profile slightly a bit of the plastic glue is applied then the brass pro-file at the joint gets a drop of super glue. Naturally, the surface brow-ning at the joint has to be cleaned off. When all the girders have been mounted the holes for the anchor bolts can be drilled into the woo-den wall keeping them perfectly horizontal. The best way to do this is to use a hand held motor drill that can be held like a pencil. The two U profiles of the brace can act as a guide for the drill however, care has to be taken that they are not touched during drilling. Other-wise, the resulting vibrations could undo the glued joints. By the way, the wooden beams of the support wall remain loose.

Ich bin ein Berliner!



Nut, bolt and washers

The double washers are also made from styrene. Both plates are glued together exactly and a 1 mm (1 mm) hole is drilled in the middle for the anchors. The an-chors themselves are made from M1 brass threaded stock cut to a

length of 20 mm. The cut surfaces are then filed smooth. The nuts are attached before being immersed in the browning solution which acts as a bond therefore no glue or solder is required to keep them in place. The nuts are attached at various depths to prevent them from all looking alike. The nut/bolt

combinations are now glued in place using a combination of ACC and plastic glue applied sparingly to the back of the NBWs (nut bolt washers).

The aging of the girders and beam assembly and the application of rust and dust weathering will be described in part three.

Komatsu Graders

Since the beginning of this year, Komatsu has been exporting gra-ders to Europe. Models GD555-5 and GD675-5 are both available and have working weights with rear ripping attachment and thrust block of 17,065 Kg and 17.885 Kg respectively. To achieve the perfect plane with the 3710 mm wide bla-de, the GD555-5 can call on a pow-er plant producing 144 kW of pow-er. The tier 3 motor of the GD675-5 has 19Kw more power output and its blade is wider by 610 mm. With a wheel base of 6480 mm, the GD555-5 is the largest grader in its class. The first European sale of the GD675-5 was for a Slovakian con-struction firm and was handled by the Kuhn-Gruppe.

Liebherr TA230

During the 2010 Bauma trade show, Liebherr presented their first articulated dump truck. The long awaited TA230 can carry a pay-load of 30 t with an empty weight of 23.3 t. Equipped with a tailgate; the load capacity of the dump body is 19 cubic meters (heaped).

The power plant is a 6 cylinder in-line engine with a displacement of 10.5 litres producing 270 KW (367 HP). The all wheel drive is an electronically-controlled automa-tic power-shift transmission with lock-up clutch. At the moment it

is a rental only machine. A total of 55 TA230 type machines were pro-duced by Liebherr. In Switzerland there are five in use by construc-tion and surface work firms.

Soil relocation in a big way

The existing inert material fill site in Lufingen ZH will be com-pletely full within the next two years. Therefore on July 19th, 2010, Eberhard Bau AG started the largest excavation project in the firm’s history nearby. A total of a million cubic meters of fill has to be moved from the 90,000 square meter site and the project is to be completed by summer of 2011. The new fill site at Häusli is being excavated to a depth of 35m. The soil removed there is reloca-ted to adjoining pieces of property and then re-landscaped. To achieve the required daily quota of moving 7,000 cubic meters of material, a large fleet of construction engines is employed. The main loading machines are a Cat 385CL and a brand new Cat 385C LME with a 7 cubic metre bucket. The trans-portation fleet consists of two Cat 740s, 4 Volvo A40E+D, 1 A35E and 3 A25D+C.

At the dumping site, a Cat D8T, D6T LGP and a Cat 815 Compac-tor are at work. For the shaping of the berms, it is planned to use two Cat 345C L excavators.
