From the Chairman’s Desk

On behalf of all our members and readers, LIFTING EQUIPMENT ENGI-NEERING ASSOCIATION OF SOUTH AF-RICA (LEEASA ) takes pleasure in join-ing our associates in congratulating the publishers of the Lifting Africa magazine and wish them a long and successful journey. This is the dawn-ing of an anticipated communication medium which has a major role to play in our future.

LEEASA is in the process of change, and we are proud to announce that we are on track with our plans mapped out some years ago.

These includes;

We have confirmation from the Engineering Council of South Africa (ECSA), that LEEASA is recognised by ECSA as a Voluntary Association.

The long awaited implementation of our “No Profit Or-ganisation” to drive the association forwards is now in full swing.

The restructuring of our membership which will include Lifting Tackle Inspectors, Operators and Riggers at all levels and many more.

The introduction of specialised training programs spe-cifically for our industry.

All these new initiatives will be explained and expanded on in the next edition of this publication.

An announcement regarding our next meeting will be on our website in the near future .

Until next time,

Ken Greenwood, [email protected]

PS. By now everyone should know that the new Driven Machinery Regulations have been published. LEEASA has issues with this publication and are busy with rep-resentation to the Department of Labour already.

Development and sales of the only South African manufactured “Compact”- Chain Block.Involved with the introduction of al-loy chain slings to SA market in 1967. Before this, wire rope slings was the only product used for lifting. Chain slings could be assembled on the spot by using mechanical coupling links, such as the hammerlock to at-tach different types of hooks and cus-tomise slings to user’s requirements.

Development and design of special-ised chain sling systems used in the sinking of mining shafts, not only lo-cally but worldwide.

Supporting a network of lifting equipment suppliers.

Conducting lifting equipment safe and correct use training to users and suppliers of chain sling and hoists nationally.

Challenges in Industry as far as lifting equipment is concernedApplicable Mining and Industrial legislation, for lifting equipment, is not clear and often contradicting as far as lifting equipment practice and procedures are con-cerned.

There are a lot of grey areas where legislation is not specific, and often incorrectly interpreted by inspec-tors, auditors and safety officers who enforce their own opinions and interpretations on the user.

Inferior and sub-standard lifting equipment being im-ported and used as price, rather that quality, has be-come the norm fromuninformed buyers.

Lack of properly compiled in house customized lifting equipment written operating procedures that should be adhered to ensure safety in the work place.

Management not enforcing a safe lifting program in the work place.

Lack of knowledge of applicable SANS and other quality standards.

Suppliers, that are not appointed by the OEMs as their agents who sell inferior quality with no technical back up or support.

Educating end users as to their responsibility with regards to OHSA and MHSA lifting equipment Regulations and require-ments.

Advice to offerThere are numerous prod-ucts on the market that can be used for lifting. The type, size and mass of the load will determine whether to use a chain slings, wire rope slings or webbing sling.

A risk assessment and or rigging study needs to be conducted before the lifting operation begins, and a full evaluation of the task to be performed must be conducted

Assess the typical service conditions, ie, normal, ardu-ous or hazardous before deciding and remember that lifting equipment is safety critical items.

There is no substitute for safety and only tested, cer-tified and properly marked lifting tackle and hoists should be used for lifting.Douglas Poole, Email: [email protected]

If anybody has the right knowledge and depth of understanding as to the nature and characteristics of a particular industry it is the industry participants themselves. So, with legislation and standards being es-tablished, the industry needs to par-ticipate, otherwise what is set and promulgated by government and its statutory bodies may be inadequate, inhibitive and inappropriately puni-tive – not just to manufacturers but also to end users.

This being said, it was discussed and agreed among the major overhead Crane Manufacturers that the Crane Manufacturers Association be estab-lished. The founding members of the association are Akanani, A J M, Con-dra Cranes, Demag Cranes and Com-

ponents, F B Cranes, Kone Cranes, Morris cranes, Pro Cranes, RGM Cranes and Verlinde cranes, with Alan O’Hara of Demag the first and duly elected chairperson.

The purpose and objectives of CMA are:

Represent South African overhead crane manufactur-ers, who are its members and serving them by being a single, united voice in the industry’s interactions with government, be it at a national, provincial or local level, and any statutory bodies, as well any other public or private organisations with regard to matters of concern or interest to the Industry, or to any individual member of CMA.

Promote and defend the common interests of its mem-bers.

Promote a positive image of the Industry as a whole.

Facilitate the exchange of information that may in any way be relevant to the common interests of its mem-bers.

Building relationships with South African, regional and international associations whose interests in any way intersect with or are similar to those of CMA.

Promote, in general, all other topics which the Board considers should be dealt with by CMA.

the Industry O’Hara is very clear. “The CMA wishes to be in-volved in the process of deter-mining the most appropriate and applicable SANS standard for Lifting Machinery Inspectors. Our concern is that suitably qualified experienced, persons are not appointed. Safety is not negotiable, no matter how good the past record of the industry may have been,” he said. “The reason for our concern is the instance of non-adherence to operating within the limitations de-fined by a crane’s classification, whatever the reason may be. In addition, cranes today are built precise-ly to work cycle specifications e.g. load weight, load frequency and crane life. If a crane is disposed of and the new owner is not aware of that specification, they could operate the crane out of spec, thus causing metal fatigue and failure. In such instances, people invariably get hurt and are even killed,” O’Hara concluded.

While the SANS 10375:2006 Edition 1, titled the In-spection, Testing and Examination of Overhead Cranes, defines a competent person as someone who has the knowledge, training, experience and qualifications spe-cific to the work or task being performed and who is registered by the relevant national authority. As safety is non-negotiable, every measure must be taken to en-sure that this standard is upheld.

So, with the classification of cranes of such critical im-portance, understanding and adhering to these classi-fications is an imperative. ISO 12482 emphasises what O’Hara said. Cranes are designed for a finite lifetime of duty, which is specified in load cycles and load spec-trum and is not principally related to calendar working time. The classification of crane duty provides the crane owner with the means to specify the intended duty of a crane in order to operate that crane in accordance with its intended use and operating lifetime.

The Crane Manufacturers Association (of America) classifies cranes as follows:Class A (standby or infrequent service): This service class covers cranes where precise handlings of equipment at slow speeds with long idle periods between lifts are re-quired. Capacity loads may be handled for initial instal-lation of equipment and for infrequent maintenance. Typical examples are cranes used in powerhouses, public utilities, turbine rooms, motor rooms, and transformer

stations. This is the lightest crane as far as duty cycle is concerned.

Class B (light): This service class cov-ers cranes where service require-ments are light and the speed is slow. Loads may vary from no load to occasional full rated loads with 2 to 5 lifts per hour, averaging 10 feet per lift. Typical examples are cranes in repair shops, light assembly oper-ations, service buildings, light ware-housing, etc.

Class C (moderate): This service covers cranes whose service re-quirements are deemed moderate, handling loads which average 50 percent of the rated capacity with 5 to 10 lifts per hour, averaging 15 feet, with not over 50 percent of the lifts at rated capacity. Typical ex-amples are cranes used in machine shops, paper mill machine rooms, etc.

Class D (heavy): In this type of ser-vice, loads approaching 50 percent of the rated capacity will be han-dled constantly during the work period. High speeds are desirable for this type of service with 10 to 20 lifts per hour averaging 15 feet, with not over 65 percent of the lifts at rated capacity. Typical examples are cranes used in heavy machine shops, foundries, fabricating plants, steel warehouses, container yards, lumber mills, etc., and standard duty bucket and magnet operations where heavy duty production is re-quired.

Class E (severe): This type of service requires a crane capable of handling loads approaching the rated capac-ity throughout its life with 20 or more lifts per hour at or near the rated capacity. Typi-cal examples are magnet, bucket, magnet/bucket com-bination cranes for scrap yards, cement mills, lumber mills, fertilizer plants, container handling, etc.

Class F (Continuously severe): In this type of service, the crane must be capable of handling loads approaching rated capacity continuously under severe service condi-tions throughout its life. Typical examples are custom designed specialty cranes essential to performing the critical work tasks affecting the total production facility, providing the highest reliability with special attention to ease of maintenance features.

The monitoring of a crane’s use does not in any way change the requirements for periodic inspections, re-gardless of the nature and type of instruments used for monitoring. Neither does it remove the requirement

for the regular maintenance of cranes. While both are critical, monitoring and inspections serve different pur-poses. Both must be carried out and serve the purpose for which they are intended. One cannot and does not replace the other.

The design working period (DWP) is derived from the design classification of a crane and is not to be consid-ered as a guaranteed operational period in any respect. Due to the probabilistic nature of metal fatigue and other influencing factors, premature failures during the DWP cannot be ruled out. However, the DWP represents a reliable estimate of a safe operational period of the crane, with due consideration to specified design regu-lations and standardized design safety factors – some-thing we will look at in the next issue of Lifting Africa.

Toco Lifting, a leader in the South African lift-ing, lashing and rigging industry, is enhancing their footprint through Africa. We wanted to know more about the company, and what they can offer to the market.They specialise in the importation, supply, assembly and repair of an extensive range of materials han-dling equipment. Toco’s market primarily covers the industrial, min-ing, shipping, construction, and manufacturing sectors, but they also serve the agricultural, marine and fishing industries.

When asked what their prima-ry objective is, Executive Director, Jonty Walls, would tell you that it

is to provide exceptional service. Whether sales, repairs or testing, they have both the expertise and premium products to achieve this consistently. Toco has been earning customer confidence for the past 14 years through their passion, knowledge and commitment to all their clients.

They see themselves as having a responsibility to be more than just a supplier, but to be a partner in their customers’ success, boost-ing performance and productivity

with their quality equipment and helping them get the job at hand done. Toco has played an integral role in various aspects, including products, consultation, advice and cost effective alternate options, on projects from the smaller right through to the larger mechanical turnkey projects like work done at Kusile Power Station.

“We have distinguished ourselves from the rest by adding value in terms of the quality of the services we offer. Service is our primary objective which includes extreme-ly short turnaround times on the assembly of all types of wire rope slings, chain slings and synthetic slings”

Walls said, “In this well-established industry people generally know the available products, but they might not know the most effective ap-proach, which could lead to serious consequences, and this is where Toco can help. We are registered

with the Department of Labour as an LME (Lifting Machinery Entity) and are members of the Chamber of Engineering Technology (COET) and Lifting Equipment Engineering Association of SA (LEEASA).”

Toco, also boast the employment of experienced and knowledgeable staff, this includes an LMI (Lifting Machinery Inspector). This means that they are able to tailor the most effective solution for each client’s needs, and underlies the compa-ny’s success. As Walls shared, “A fair measure of the quality of a company is the amount of repeat business it receives. We listen to our customer’s needs and exceed their expectations, and as a result they are satisfied with the equip-ment they purchase from us, not only today, but in the future.”

It is with this in mind that Toco Lifting recently launched a new website; www.toco.co.za. Visitors and customers can now browse through the products offered, see product information, and request quotations or information has-sle-free online. Convenience and efficiency is key. This support their commitment to building a commu-nity of Toco customers throughout Africa.

FootprintToco’s Head Office and principle distribution centre is situated in Gauteng, South Africa. Mr. Walls explained that “We have recently purchased a premises in Germiston, which has allowed us the space to expand further. We are able to

keep a much larger inventory of stock on hand, which once again enhances our turnaround times and supports our goal of service excellence”. Toco’s coverage has already stretched well into Africa. “We’ve been to other countries, such as Zambia and Zimbabwe to address wire rope problems on drill rigs and have been on innumerable mines. Often the end user is not fully aware of all the factors which influence the choice of wire rope, and so we go out to investigate, to work out a solution for that specific application.”

ProductsThe company specialises in Lifting Equipment below the crane hook; consumables that regularly need replacing to comply with safety requirements. Jonty added, “Our range covers world-class Vital chain blocks and Vital lever hoists, steel wire ropes, chain and rigging hard-ware such as shackles, wire rope

clamps and turnbuckles, as well as wire rope, chain and nylon slings, which is made up in-house accord-ing to the customer’s needs”

While chain blocks and lever hoists are one of their primary products ranges, steel wire rope is another speciality. “This ranges from sim-ple stuff like PVC coated wire used for pull wires on conveyor systems, right through to steel rope used on overhead, tower and mobile cranes. We also have all types of steel rope for winches as well as our in-house facility to assemble steel wire rope slings from a diameter of 1mm

right up to 56mm”. All associat-ed specialised services are also on offer, for example socketing, hand splicing and load testing.” Jonty shared.

Toco’s flagship product range is the internationally acclaimed Vital ® Chain Blocks and Lever Hoists.

Vital ® is the most extensively used chain block worldwide, and for sol-id reasons! This heavy duty chain block is designed for extended use at the lowest possible cost per use. Pricing, size, weight, mechanical advantage and efficiency sweeps the competition away! The equip-ment is designed for reliability, easy operation and uncompromising safety.

This allows for many advantages. As gears take the most strain un-der a full load, Vital ® units have been designed so that strain and backlash is greatly reduced, allow-ing for minimal wear and tear on

the gears. Vital has a unique spine fitment design of the hand wheel to the pinion shaft that offers easy main-tenance and enhances the mechanical friction braking system, the overall effect being one of great efficiency and longevity of the unit.

Vital ® units are fitted with a double ratchet pawl that is SANS1636 compliant, a mechanical friction braking system that is further strengthened with high quality, high performance abrasive brake disks.

To complete the high performance of these hardy chain blocks and lever hoists, they are fitted with anti-slip

hooks, and a standardised high grade chain, sourced from McKinnon Chain, a Division of Scaw Metals; an SABS and ISO compliant chain manufacturer. One can find no other to rival in price vs performance, and that is why Toco Lifting is proud to be the sole agents of the Vital ® Chain Blocks and Vital ® Lever Hoists in South-ern Africa.

Maintenance and RepairsLifting equipment, by its very nature, is under con-stant stress and therefore it requires regular mainte-nance to sustain capacity, safety and reliability. This maintenance should only be carried out by experi-enced staff who have the necessary knowledge and skills, and Toco, is filling this role, aspires to be the service champion in their industry.

They are dedicated to the highest level of customer service over the life of their equipment. They strip, quote and repair all types of lifting and rigging equipment, including manual hoists, electric hoists, pneumatic hoists, winches and chain slings. They then test the equipment on testing benches, and once they are satisfied with the quality of repair, a certificate for each repair is supplied.

A wide range of spares are carried by the com-pany, and original parts are sourced where re-quired. Their reputation has been established as a company that offers expertise, experience and

in-house equipment to conduct professional in-spection, testing and repairs in accordance with all applicable regulations, standards and engineering practices, ensuring that even products sold by other suppliers are brought to Toco for repairs and maintenance. Tested and repaired products leave the company recertified and ready for use.

Toco Lifting’s dedication to service and integrity is a clear winner

“What we value the most is the relationships we build up with customers in the long term,” Jonty says in con-clusion. “It’s very important to provide your customers with the best value for money while maintaining the integrity of the product once we’ve sold it to them by providing jacked-up after-sales service”.

Make sure that you have received prop-er training (both general training and hands-on practical training) as well as familiarization on the MEWP you will be using. Thoroughly read the opera-tor’s manual and safety signs on the machine, and understand the func-

tion and location of all safety devices and controls be-fore beginning operation.

Always read, understand and obey employer’s safety rules and worksite regulations, as well as all applicable local, governmental or provincial regulations that apply to MEWP operation before operating the machine.

Always perform a pre-operation inspection and func-tion tests on the MEWP before each shift. A level sensor, alarm or any other safety device cannot do its job if it has been disabled or has malfunctioned. If the ma-chine fails any of these tests, make sure it is immedi-ately tagged and removed from service until it can be repaired by a qualified service technician.

Always perform a workplace risk assessment prior to moving the MEWP to the job site. Look for drop-offs and holes, slopes, slippery or unstable surfaces, over-head obstacles, power lines and any other hazards that may exist. Then consciously think about and avoid those hazards through all phases of machine operation. A full list of hazards you need to be aware of can be found in the operator’s manual for the machine you are operating.

Always wear the proper fall protection when operat-ing either a telescopic or articulating boom. A proper-ly fitted full body harness and appropriate lanyard or self-retracting lifeline is an absolute requirement. Most operators do not understand the potential for being catapulted from the platform of a boom. The slightest jar at the base of the machine can equate into a sudden and powerful whiplash at the platform that may have the potential to toss the operator into the air. If this were to happen, wearing the proper fall protection may reduce the chances of serious injury or even death.

Never sit, stand or climb on the platform guardrails for any reason. The guardrails on a MEWP provide fall pro-tection only if the operator maintains a firm footing on the platform floor at all times. If an operator is required to reach an overhead work area that is too small for

Fatalities caused by falls from elevation continue to be a leading cause of death for construction workers, accounting for 269 of the 775 construction fatalities recorded in 2012. According to Scott Owyen, global training man-ager for Terex AWP, those deaths could have been prevented. In honor of OS-HA’s National Fall Prevention Stand-Down, June 2 – 6, Terex AWP is providing the following safety tips for operating powered access equipment to reduce the likelihood of a potential deadly fall.

the platform guardrails to allow access to, the use of a manufacturer-approved device that has been specifi-cally designed to provide additional access to confined spaces is recommended.

Never exit an elevated boom or scissor lift platform un-less you have been properly trained to do so, maintain 100% tie-off at all times, and are in possession of an

approval letter from the manufacturer that provides the proper guidance.

Never climb down from the platform when it is raised. Whenever possible, keep a cell phone or two-way radio with you while you are in the platform. Al-ways have a rescue plan in place in the event that the MEWP is not equipped with an auxiliary lowering system or if that system malfunctions. Rescue plans should at a minimum include steps to ensure that other personnel are aware that you are operating the MEWP and that they have been trained and famil-iarized to operate the machine from the ground controls.

Always keep the platform floor clear of debris. Scrap materials, buckets, large tool boxes and other items can cause a serious tripping hazard. You should re-move any item from the platform that is not absolutely necessary to do your work. Utilize special manufacturer-ap-proved attachments such as fluorescent tube caddies or panel cradles (where ap-

plicable) to lift large or bulky items.

Always lower the platform entry mid-rail or close the entry gate before operating the MEWP. The entry mid-rail or gate is an integral part of the platform guard-rail. Never tape or prop the entry open and never use a MEWP if the gate does not properly latch.

The correct use, main-tenance, inspection and testing of chain blocks and lever hoists, re-ferred to as hand pow-ered lifting devices in the new OHSA DMR 18, is essential to be legally compliant and to main-tain safety in plants, mines and industry. It is a fact that hundreds of thou-sands of these units are in use and are often abused, overloaded, incorrectly inspected and poorly maintained.

With this in mind and to assist us-ers, Phakamisa Safety Consultants have added this new course to their other specialized lifting equipment management and inspection cours-es, which are conducted on site or at pre-arranged venues in major centres

This unique half day intensive course has been designed by Phakamisa, in cooperation with major hoist suppliers, to assist sup-plier’s technical representatives, users, inspectors, artisans, safety staff, Riggers, LTIs and LMIs to gain the necessary knowledge of the operation, safe use, inspection and maintenance of hand powered lift-ing devices as well as other equip-ment such as suspension trolleys.

The course covers all legal re-quirements in accordance with OHSA-DMR 18 and MHSA require-ments as well as definitions, mark-ing, certification, SANS and other quality standards as well as LME and LMI requirements.

The course will assist users to con-duct visual daily and mandatory visual inspections on hoists and maintain and store properly.

Hoist Inspection check lists are pro-vided for a proper visual inspection.

Hoists must be visually inspected, in accordance with proper inspection check lists, by persons who have been appointed, by company man-agement in writing, based on that person’s experience, knowledge

and training to conduct mandatory visual inspec-tions.

Hoists must also be load tested at maximum in-tervals of twelve months, by companies registered as LMEs with the DOL. These LMEs must em-ploy or contract suitably qualified ECSA regis-tered LMIs who have the scope to conduct tests on hoists.

This intensive training course provides the nec-essary knowledge re-quired for selected and experienced candidates, through properly struc-tured course modules and demonstration to be

program, by all candidates. Certifi-cates will only be awarded to those who achieve a pass rate of 70%.

As far as accreditation is concerned, this specialized course is unique and no specific formal SAQA Unit Standards exists for it.

The course is essential for the hoist component of LMI and LTI training

The course is validated by ECSA for CPD points.

It is essential to note that candi-dates who are nominated for this intensive course must be carefully selected by management by virtue of their background, experience and practical skills and ability to conduct proper inspections after completing the course.

Remember, safety is not negotiable and all lifting equipment, including chain blocks and lever hoists must be regarded as safety critical items!

The downside of a preventable acci-dent is the avoidable injury or death, caused as a result. Not to forget the costs involved. Causality teaches us that accidents caused by metal fa-tigue are solely attributable to neg-ligence.

Walking into a Meyerton factory that produces spirally welded steel pipes, I asked the safety officer why he had not given me a helmet, but had insist-ed I wear ear plugs and a reflective vest. He pointed to the coil of sheet

steel hanging from the overhead crane and explained, “That coil weights 30 tonnes. If it falls on you, a helmet won’t matter at all.” A valid point indeed! Without an-other thought, we continued into the factory. On reflec-tion, I should have considered the issue a little more. Over the years the overhead crane could have suffered

metal fatigue, and failed. Was this a real possibility, or just a lit-tle imagination off on the wild side?

When initially clas-sified, this overhead crane was regular-ly lifting 22 tonne coils. With advances in steel manufacture, coil weights increased to 30 tonne, giving a 36% increase in weight

above the original classification. If the overhead crane was not upgraded, this would have exposed it to loads above and beyond its design capacity, and effectively shortened its life, which is usually 10 years.

“Causality teaches us that accidents caused by metal fatigue are solely attributable to negligence”

Could this possibly happen? In South Africa, with its normal rate of staff attrition, BEE legislation and exo-dus of skills, corporate memory and intellectual capital often do walk out of the door. Eskom is but one exam-ple.

While failures due to metal fatigue don’t occur very often, they do occur. In one accident, the shaft in an overhead crane motor failed. Professor Sara Rodriguez, assisted by Oscar Zambrano and JJ Coronado from of the University of del Valle’s mechanical engineering de-partment, and members of a research group looking into metal fatigue failures, analysed the failure of the shaft.

“The shaft fractured in the keyway with clear evidence of fatigue. Chemical analysis, micro-structural charac-terization, fractography, hardness measurements and finite element simulation were used for the analysis. The microstructure was predominantly tempered mar-tensite. Large amounts of oxides, micro pores and man-ganese sulphide inclusions were found. The geometry of the keyway also initiated the original crack because the width and height were erroneously designed,” Ro-driguez said.

“From this we concluded that these factors in combi-nation produced the fatigue failure,” Zambrano added.

“From our analysis and conclusions, we recommend that the chemical composition and microstructure of


Out-of-plane shear: a shear stress acting parallel to the plane of the crack and par-allel to the crack front

The Goodman Relation is an equation used in linear elastic fracture mechanics to quanti-fy the interaction of mean and alternating stresses on the fa-tigue life of a material. The Goodman diagram is a graph of (linear) mean stress ver-sus (linear) alternating stress, showing when the material fails at some given number of cycles.

The Goodman relation can be represented mathemat-ically as:

Where is the alternating stress, is the mean stress, is the fatigue limit for completely reversed loading, and is the ultimate tensile stress of the ma-terial. The general trend given by the Goodman relation is one of decreasing fatigue life with increasing mean stress for a given level of applied stress. The relation can be plotted to determine the safe cyclic loading of a part; if the coordinate given by the mean stress and the applied stress lies under the curve given by the relation, then the part will survive. If the coordinate is above the curve, then the part will fail for the given stress param-eters.

In another instance, as Mark Firth, senior consulting en-gineer at Hanson Materials Engineering, relates, “The driveshaft of a 36 tonne capacity overhead crane in use in a foundry had failed after slightly less than one year's service. The shaft was 188 mm in diameter at the point of failure. It was a replacement unit which had been machined from plain carbon shafting steel (0.4% C).”

“From visual examination of the fracture face, it was obvious that the shaft failed be-cause of fatigue. The fracture had initiated at four locations and had two distinct origins - at a minor change of section of the shaft from 188 to 191 mm, and at the base of the end of a keyway.”

“The fatigue fracture occupied ap-proximately 40% of the shaft cross section. The remainder of the cross section showed a ductile torsion-al failure. The change of section of the shaft diameter was fully ra-dius’d (1.6 mm), but appeared to have been made with a worn tool

“pssaodhThe three fracture modes

the material, at time of manufacture, must conform to regulatory standards, and be guaranteed. That magne-sium or calcium additions in the steel casting process, to obtain better shape control of inclusions, should be used. And lastly, that the geometric parameters rec-ommended by the regulatory standard, to avoid high stress concentration factors, should be met,” Rodriguez concluded.

As Kai Qi, Guangzhou’s academy of special equipment inspection and testing explained, “Based on fatigue crack growth analysis, linear elastic fracture mechanics (LEFM), the study of the propagation of cracks in mate-rials, can be used to describe, and predict, fatigue crack growth in the life estimation process of metal compo-nents of a crane.”

There are three ways force can be applied to enable crack propagation:

Opening mode: a tensile stress normal to the plane of the crack

In-plane shear: a shear stress acting parallel to the plane of the crack and perpendicular to the crack front

because the fillet had a rough surface con-taining many grooves. The base of the key-way was also sharp and had no radius.”

These deficiencies in machining were con-sidered to be the major cause of fatigue failure.

“The material itself was open to criticism; although the shaft had a normal fer-rite-pearlite microstructure characteristic of a shafting steel, the hardness at HB 176 was lower than the typical value (HB 192) quoted by the steel manufacturer. Tensile testing of samples of shaft material showed that although tensile strength levels were in accordance with the manufacturer's typ-ical value (655 MPa), yield strength levels (328 MPa) were appreciably lower than the typical value (393 MPa). Low yield strength no doubt contributed to the fatigue fail-ure,” Firth concluded.

But, it’s not just driveshafts that fail. Oth-er components of overhead cranes can also fail, such as:

Bolt slackness / poorly welded joints

“I” beam support failure

“I” beam failure

Hoist rope failure

What is clear from these and other examples of metal fatigue failure is that negligence in manufacture, short-cuts in maintenance, pushing an overhead crane be-yond its design life, or designed load classification, and ultimately a failure of the regulatory inspection cycle to identify and/or prevent fatigue is what causes acci-dents.

When it comes to safety, the attitude “we had to cut costs” is a negligent one, as is “it will never happen to me”. Safety has no price. Accidents can be avoided. Metal fatigue can be avoided.

“Ultimately, a successful heavy lift is determined by the technical exper-tise of the heavy lift sup-plier. Johnson Crane Hire

has a breadth of resident knowledge that enables it to provide best prac-tice heavy lift solutions in a turnkey project approach that includes rig-ging and transportation,” says James Robinson, heavy lift manager for the crawler cranes and projects division at Johnson Crane Hire. “We are able to offer flexibility in terms of heavy lift-ing solutions because we operate a crawler crane fleet and a hydraulic mobile crane fleet as well as alterna-tive lifting solutions.”

Robinson points out that the three largest cranes in the Johnson Crane Hire fleet are its 750 ton and 600 ton lattice crawlers and its most recent addition – a 750 ton truck mounted lattice mobile unit. “This level of heavy lifting capacity provides continuity and shows our level of commitment to the market by providing them with access to an unequalled combination of heavy lifting capacity and technical expertise.”

Robinson cautions that there is a critical need to rec-ognise that a lattice boom crawler crane offers a vastly greater lifting capacity when compared to mobile hy-draulic crane lifting capacities. It is not uncommon to find people making the mistake of comparing one with the other as the nomenclature can be very misleading.

As an example, Robinson points out that the 250 ton lattice boom crawler competes against a heavy lift 400 ton hydraulic mobile crane. These machines have equivalent lifting capacity, but this not obvious to those that do not understand the differences between lattice boom machines and mobile cranes. The nomenclature should not be used as the manner in which to differen-tiate between capacities and capabilities.

Crawler Crane Fleet Provides

The Heaviest Lifts

Undertaking a heavy lift is not a case of ‘one size fits

all’ but rather about se-lecting the most appropri-

ate lifting solution for a given project or contract. This is according to John-

son Crane Hire, which boasts a heavy lifting ca-pacity unmatched on the

continent.CR

“In explanation, a hydraulically operated mobile crane’s lift capacity is rated on what is referred to as the load moment. Most hydraulic cranes are rated at their ca-pacity at 3 metres, whereas the rating for a lattice boom crane is based on a larger load moment, which can be anywhere between 7 to 14 metres and this ca-pacity is based on its structural integrity. In essence, a lattice boom crawler crane is capable of performing far heavier lifts and offers greater flexibility in terms of its application because of its pick and carry capability,” he says.

There are distinct limits with regard to the amount of counterweight that can be placed on a hydraulic mobile crane and this is where a crawler crane excels. The lat-tice boom configuration allows for the attachment of an additional counterweight most often referred to as the super-lift ballast. Crawler cranes are able to increase their load moment by balancing the load to be lifted against the super lift ballast.

Johnson Crane Hire has a ten year history in the crawler crane market and has amassed a number of impressive lifts, including a recent heavy lift at Zimplats. “We were contracted to remove an old mill weighing 225 tons, with a radius of 31 metres, and to replace it with a new one weighing 170 tons. We then brought in an LR 1600-2 (600 ton) crawler crane from Europe to per-form this work. The crane is now part of our permanent fleet,” Robinson says.

Johnson Crane Hire also used the LR 1750 (750 ton) crawler crane to lift a 280 ton tippler in Mozambique for the Nacala port upgrade project. A notable feat achieved by the team was the lifting of the 280 ton assembly in one execution. The company is also actively involved in heavy lifts for the major expansion under-way at a diamond mine in South Africa. A recent lift at this mine required the lifting of a 110 ton structure with luffer and full super lift configuration at a 55 metre ra-dius. There are additional lifts planned for equipment of 200 tons at 35 metres in the same configuration.

On all lifts, the company provides a full pre-lift feasibil-ity study that includes computer simulated drawings, generating method statements, full risk assessments and load studies. Operation of the well maintained crawler fleet is supported by an experienced technical team with in-depth knowledge.

Safety in the complex operation of heavy lifts is para-mount. “Adherence to safe operation comprises a num-ber of critical elements. Firstly, our machines are current technology and well maintained, and our operators are skilled and comprehensively trained. In addition, we im-plement carefully documented and implemented safety systems, which comply with all industry safety stan-dards. This is complemented by the risk assessments conducted before each lift. We are justifiably proud of the fact that safety as a culture is ingrained in every Johnson Crane Hire employee,” says Robinson. Safety in fact forms part of the company’s holistic lifting pack-age, referred to as the ‘SMART’ (Safety, Maintenance, Availability, Reliability and Total cost effectiveness) phi-losophy.

In addition to the existing Toyota fork-lifts in Woolworths’ fleet, three wheel electric forklifts were supplied as well as IPX4 rated four wheel electric fork-lifts, which are the world’s first elec-tric forklifts with the ability to operate in the rain. BT Reach trucks, order

pickers and LPE power pallet trucks also complemented the supply of the electric counterbalanced trucks.

About 3 years ago, Woolworths was operating 50 units with 5 different vendors over 3 sites. “Our fleet had been purchased on an ad hoc basis and specifications had never been standardized. A renewal program was initiated with the following primary aims in mind; 1 na-tional MHE vendor, standardized national specifications and clear end to end costing. Toyota Forklift offered these as well as a relationship that allowed for mutual growth,” described Michael-John Newham from Wool-worths.

“We delivered material handling equipment accord-ing to the customer’s specifications which was fitted with world leading and first in the country Trak air sys-tem batteries and chargers with Battery WIQ, a wire-less monitoring tool for the batteries,” explained Leric Smith, Product Manager for Toyota Forklift.

InnovationWoolworths is known for its passion in quality and in-novation as well as bringing in new concepts to ensure safety in the warehouse. The retail group introduced Tyri BluePoint LED lights for use in their warehouses. The coloured concentrated light beam displays a large and visible square on the floor in front or behind the ma-chine to alert workers that a machine is approaching. This industry leading concept allows safety to be visual instead of relying solely on sirens and alarms, especially in loud noisy workplaces where hearing is difficult.

Woolworths went on to select Toyota Forklift’s equip-

ment because of their international award winning Toyota I-site fleet management solution which would further increase safe-ty levels in their ware-houses.

Toyota I_SiteToyota I_Site is an ad-vanced fleet manage-ment business solution that helps companies

optimise their fleet size by increasing safety, reducing cost and improving productivity.

“Continuous customer support for Toyota I_Site is avail-able from trained and certified specialists,” notes Smith. “The various features of this system all help to improve efficiencies and give information to ensure proper and informed central management of the entire fleet,” he adds.

According to Newham, the new machines have im-proved cross docking efficiencies ensuring product is loaded quickly, safely and on time. The retail giant is now able to move 3 picking bins at a time instead of only one bin with the previous machines.

“Pallet put-aways and retrievals are a lot faster as well as smoother lift speeds, thanks to the modern equip-ment,” he adds.

“Longer operating times on all equipment also im-proved with all equipment being AC power and the ad-dition of TRAK Air chargers. The inclusion of the I-site system and access to Toyota Forklift’s well-trained and managed support services has allowed the partnership to grow and enrich both parties,” noted Newham. “The tools available on this system ensure correct spread of equipment is being used to ensure maximum uptime.”

“The pre-check op devices installed on Woolworth’s ma-chines play a big role in assisting a business go green as it saves paper and ensures drivers do their daily checks; a legal requirement, and to make sure the equipment they are about to operate is safe to use. Equipment is thus properly looked after, increasing the life span of the equipment,” advises Smith. “This system helps achieve an initial upfront investment saving and lowers cost of abuse and inefficiency costs over the term,” he concludes.

Built in 1962, the sta-tion is being renovat-ed and expanded since 2009 to increase its energy production by 80%. From the cur-rent 180 MW per

year, this infrastructure will then produce 960 MW, becoming the largest power production plant of the Kwanza basin. In 2014, Cam-bambe was certified with ISO 9001, 14001 and 18001 seals, being the first hydroelectric project in Africa to obtain such recognition.

Part of the project which is be-ing conducted by the Brazilian construction company Norberto Odebrecht is the rise of the dam’s height by 20 metres. This heighten-ing will increase the capacity of the reservoir from 2 to 5.5 km2, and allow the four existing generators to produce 65 megawatts each in-stead of the present 45.

In order to put into place the over 65,000 cubic meters of concrete needed to rise the dam, Odebrecht counts with the help of three Lin-den Comansa tower cranes: two 21LC750 with maximum load ca-pacity of 48 tons acquired in 2012

In December 2015 the regrowth works of the Cambambe hy-droelectric power station, in the Kwanza River, about 180 ki-lometres Southeast of Luanda, the capital of Angola, will be concluded. This dam currently supplies power to the cities of Luanda, Ndalatando, Cacuaco, Malanje, Gabela, Porto Ambo-im and Sumbe, benefiting a population of approximately 8 million people.

and a 21LC400 with maximum ca-pacity of 18 tons leased by IBERG-RU, the exclusive distributor of Lin-den Comansa in Angola.

The first 21LC750 was located on the left bank of the Kwanza Riv-er, erected with fixing angles on a special concrete foundation which, given its short width, was an-chored to a rock on the river bank. It was mounted with a freestand-ing height of 78.8 meters, the max-imum possible height with 2.5-me-ter-wide mast sections (fourteen D36 sections), and a jib length of 80 meters.

On the right bank, a second 21LC750 was erected with a free-standing height of 87.2 meters, achieved with 12 sections D36 - as her "sister" in the left margin - in-creased by three 5-metre-wide D56 sections at its bottom. Another concrete foundation was anchored on the riverside to allow this crane’s assembly on fixing angles.

After a year and a half working in concreting and materials lifting tasks, the first 21LC750 (left bank) was relocated within the jobsite and substituted by a 21LC400

from IBERGRU’s rental fleet, which was erected with a freestanding height of 80 meters and a jib length of 70 meters. This crane was assembled on the same fixing angles of the pre-vious 21LC750, so it was necessary to have two tran-sition sections in order to allow the progression from the 4 meter-wide fixing angles to the 2.5-metre-wide D33 mast section.

The relocated 21L C750 is currently working on the construction of the power house (or power generation center) where it was assigned to moving precast segments up to 19 tons of weight for the new water tunnels, as well as lifting and placing all the electromechanical gear that will allow the production of energy, such as turbines and gener-ator sets.

The assembly and jacking-up of the first 21LC750 was performed by Linden Comansa’s technical assistance service team, while the remaining assemblies, jack-

ing-ups and technical service was entrusted to IBERG-RU.

IBERGRU is the official distributor of Linden Comansa in Portugal since 2002. In 2008, the company opened offices in Angola, where it offers its tower crane rental services as well as technical planning and coordination for all kinds of lifting projects.

A mobile crane owner has a multi-million Rand piece of equipment, with an operator doing multi-million Rand lifts.As an owner and operator you should and the custom-er believes that you know the best way to lift their par-ticular item and the safest way as well.

In the ever-changing world of Mobile Crane Opera-tions, it is more important than ever to stay up-to-date with the regulations as well as best practices.

Here are 10 tips you can use to help ensure success:

1. Never override the mobile crane’s computer.

2. Be aware of all overhead hazards – specifically close-by buildings and any power lines that are within the working zone of operation.

3. Read the load charts – prior to turning the key in any new mobile crane.

4. Cell phones in the cab – while the crane’s key is on the cell phone is off. (preferably no cell phones in the cab at all times).

5. Always note the changing conditions on the

jobsite – from personnel to weather to sur-roundings.

6. Sometimes in a working situation, the crane operator needs to stop, evaluate, and find a safer lift plan.

7. Check ground conditions – before crane setup, ensure that the site is suitable to support your mobile crane and the future suspended loads.

8. Use appropriate pads & cribbing – mobile crane operators need to make sure they are using correct pads or cribbing to avoid having an outrigger fail or sink when they are making a lift.

9. Before starting your crane, always double check the oil, gas, and other fluid levels (maintenance of the cranes are everyone’s lively hood and success).

10. At the beginning of your shift, walk-around your crane checking for mechanical, electrical, structural, and hydraulic issues (MESH).

South African crane manufacturer Con-dra has reported an increase in exports to Canada, the result of increasing awareness of product capabilities in that country.

The company’s agent in Saskatch-ewan believes that Canadian engi-neers are gradually accepting the long term advantages of install-

ing robust, durable cranes instead of the more delicate machines of some northern hemisphere manu-facturers.

Orders mainly comprise hoists up to 60 tons, overhead cranes up to 40 tons, and spares, delivered pre-dominantly to customers in mining.

Although the Canadian export in-crement is small as a percentage of total manufacturing volume, the upward trend is seen as significant by management.

Condra entered the Canadian mar-

ket at the beginning of 2011 in response to initial orders from ex-patriate South African engineers familiar with Condra’s combination of a rugged, reliable and robust hoist and crane design enhanced by innovative drive and control technology to deliver an impressive overall capability.

In the same year, a local agent was appointed to manage sales, in-stallation and servicing across the product range.

Over the four years since, word of the reliability of these South African manufactured machines has spread beyond the expatriate engineer-ing fraternity, mainly because the cranes continue to work in hostile mining environments when their European and American equiva-lents have broken down because of skipped services.

The Condra service interval is gen-erally longer than those of compet-itors’ machines.

“South African engineers deliver an impressive overall capability”

which allows application flexibili-ty without a disproportionate in-crease in price to the end-user.

An example of this is the use of standard hoists as a platform from which modifications to customer specification can be accommodat-ed. For high-lift applications, the company regularly adapts units to deliver a 15-metre lift, more than twice the average lift height of 6,8 metres.

Condra’s mandate to continually drive down product maintenance costs is ongoing, two examples being the use of live-axle drives in place of ring-gear designs, and the introduction of adapted V-belt technology which has already been tested and proven in the motor ve-hicle industry.

In this way, the total cost of the crane over a typical useful life is lowered.

Extending crane lifespanFor some years now, Condra has incorporated very high quality ma-terials in component manufacture. Gearboxes have been up-rated to deliver additional power, and the company is using a 36B case-hard-ened material on most pinions. This material, though expensive, is

beneficial in extending crane lifes-pan.

Hoists are also usually fitted with high tensile-strength ropes. The re-sulting reduction in rope diameter enables use of a reduced drum di-ameter and a smaller gearbox and

motor, all of which help contain costs.

Compliance with ISO and other in-ternational quality standards have also helped Condra to drive export sales to Canada.

Company management expects high product quality, lower main-tenance costs and lower overall useful lifetime costs to continue to contribute to Condra’s sustainable competitive advantage in markets worldwide.

In the old days it was a case of many hands make light work, while this re-mains true, technology today makes even lighter work, thereby increasing productivity and reducing costs.

In the blockbuster movie,” Mission Impossi-ble: Ghost Protocol”, there is a scene where Ethan, played by Tom Cruise, climbs the side of the world's tallest building, the Burj Khalifa, using a pair of gecko-like suction gloves. Was this fantasy or reality?

In the Myth buster’s 54th episode, presenters Adam and Jamie proved that this was no myth. Adam climbed an air duct using Suction Cups. Not to be outdone, the BBC’s Bang Goes the Theory presenter, Jem, scaled the side of the aluminium cladded BBC building using ‘Spi-derman’ style vacuum gloves. Inspired, a 15-year old Cambridge schoolboy did the same thing, but on a brick-faced building, and used two domestic vacuum cleaner motors. Until these events took place, it was believed impossible.

Moving to the factory floor, the same spider-like technol-ogy exists, not for climbing but for lifting. In South Africa vacuum lifting technology is relatively new. However, in the USA, Europe and the Far East, vacuum lifting equipment is widely used in many industrial sectors for the lifting and han-dling of materials/components that have a flat or smooth sur-face. In particular materials such as metal, glass, concrete slabs, pipes, plaster boards, plastic laminates, cement

bags, beer kegs and so on. These products can be eas-ily lifted and handled using vacuum lifting equipment fitted with suction pads that attach to and lift loads as much as 45 000 kg in weight, and more. No doubt the usual sceptics will say this is impossible. The pictures below tell a different story.

There are two basic types of vacuum lifting equipment:

Vacuum lifting tubes (VLT): A lifting system, a ma-chine, incorporating a vacuum tube with suction pads used for both gripping and lifting the load.

Vacuum lifting attachments (VLA): A detachable lifting attachment incorporating suction pads that is fixed to an independent lifting machine (eg, at-tachment to a crane or hydraulic excavator arm or

forklift truck. The attachment is used for gripping the load and the machine used to lift the whole assembly.

The difference between a VLT and a VLA is that VLT is used for both gripping and lifting the load, but a VLA functions as an attachment for just gripping a load and not lifting it.

The advantages of vacuum lifting and material han-dling technology are:

• Fast and simple handling: The vacuum’s sucking and releasing steps only need a few seconds to complete activation.

• Reduction of production costs: Higher productiv-ity is achieved through the use of this fast, easy to use technology that requires less man power and that has a lower energy consumption rate.

• Reduced wastage: No matter the load, this tech-nology causes no damage, such as scuffing or graz-ing.

• Safety first: With double safety factors giving a re-liable safety provisions even in the case of power failures/load shedding.

Sheet metal handlingMoving sheet metal is usually a challenging process, with much care needed. Using the more traditional methods, one simple error and a slipped sheet can cut a man in half. Thinner sheets have proved particularly difficult to handle due to lower intrinsic stability. Even large sheets can be quickly picked up and moved, over long distances, to the next phase in the production pro-cess.

The simplicity, with which the vacuum lifter can be operated, with an adjustable, angled handle and one

The South African connection

As with everything, manufacturing quality, reliability, service and sup-port are critical. The Aero-Lift range of vacuum lifters, which are man-ufactured in Germany by Aero-Lift Vakuumtechnik GmbH, are repre-sented in South Africa by WH Lifting & Handling CC.

Werner Hurlimann, founder and tech-nical director at WH Lifting & Han-dling CC, and originally from Switzer-land but now proudly South African, said, “We expect vacuum lifting to take-off in South Africa as it really is a solidly engineered technology that can bring huge productivity gains to a ranges of businesses where materi-al handling plays an important role. More over, we have been in South Africa for the last 20-years and have built up a substantial skills base in or-der to provide a first-class installation and maintenance support service.”

hand, makes sheet metal handling a breeze. Warp-ing or even bending of the transported sheet metal is avoided through proper configuration of the suction plates to suit the dimensions involved. Depending on the application, each sheet metal vacuum lifter is classi-fied according to its maximum load and load frequen-cy. A pivoting range of 90o gives the vacuum lifter the


flexibility needed in a typical production environment. If needed, a vacuum lifter can be fitted with an 180o horizontal turning capability.

Whether the sheet metal is being used to manufacture air ducts or big ships, handling light to very heavy metal loads is no longer a cumbersome process. Even lifting and placing IBR roof sheeting is made simple. The re-liable traversing system, intelligent suction plate con-figuration, with all components manufactured to the highest quality standards, ensures a safe, stable and yet quick mechanism to transport sheet metal to where it is needed.

Wood handlingWood is an extremely sensitive material that must always be handled with care. Scratches and damage ultimately spoil the product. Vacuum lifters are perfect solutions for wood handling on the factory floor, be this chip board or solid wood – because this technology is wood friendly. The fact that some woods are more porus than

Handling wood, without damaging the wood, has never been easier

others makes no difference. A high-performance blower sorts this out. With a maximum size of 7 m x 2.1 m and/or 500 kg, coupled with the sin-gle-handed operation, vertical pivot and horizon-tal turning capabilities, the vacuum lifter is the perfect wood handling tool. Be it in a sawmill, warehouse or furniture factory, or on a construc-tion site, handling of heavy joists, planks, wood laminate beams or block planks is made simple, fast and reliable, without machine damaging the wood.

A rather interesting application is the box mod-ule, for finished products such as preassemble parts, cabinets, housings and boxes. This module gently grabs the piece on each side and trans-ports it further. Another ingenious development is the VUSS vacuum gripper that enables the vac-

uum pads to lift a board despite any milled-out por-tions. A vacuum is only created in areas where there is wood flush. The vacuum lifter can be used in conjunc-tion with a pillar-mounted slewing crane, articulated arm jib, rail system or electric chain hoist.

Other applicationsCladding, window repairs, roofing and window fitting has never been easier either. Tailor-made variations of VLT and VLA vacuum lifters can be used for a myriad of applications, even in glass-clad high-rise building con-struction using UV-resistant suction plates. Electricity mains-free versions for cladding and construction are

also available.

With companies such as Group 5, Bell Equip-ment, MacSteel and TFM already using vacuum lift technologies from Aero-Lift in their day-to-day manufacturing processes, they obvious-ly don’t doubt the capabilities of this amazing technology. Clearly, Ethan Hawk’s antics with vacuum power are no longer the realm of movie fantasy. It’s time to be stuck onto real power.
