FROM THE CHAIRMANS DESK As we move to a possible end to lockdown that was put in place to protect our own lives and the lives of our families we have had to face the realisation of a new form of normal. It has not been easy for any of us as our lives were turned upside down effecting our potential to earn a living without being exposed to the disease. Engineering Council and Meetings, After all the scheduled meetings were cancelled in the first few weeks of lockdown the CEO instructed those responsible for meetings to reinstate those meeting as video conference meetings (VC – virtual meetings) after ECSA staff members and administrators where given means to hold online meetings. This meant that I have attended four Hight Impact Committee meeting and an ECSA Council Meeting and the ongoing steering committee and working group for the overarching Code of Practice for the Performance of Engineering Work, in the lock down period: CRC – Central Registration Committee meeting 6th May 2020. The very first ECSA VC meeting was the CRC meeting and it was clear from this meeting that this meeting was very important as the first meeting as I and a number of other members were getting very concerned with the backlog of applications that would be building up since the registration process had come to a standstill since the beginning of lockdown. The CEO of ECSA acknowledged that this was a priority and that the first one third allowed by lockdown of staff would be the registration administration office.As the CEO of ECSA pointed out in this meeting that ECSA had to provided staff means to work from home by supplying them with computers and data packages. At the end of this meeting it was clear 6
Lifting Africa - May/Jun 2020
that another ad-hock CRC meeting need to be held as soon as possible. CRC – Central Registration Committee meeting 27th May 2020. The second CRC meeting was held and, on this date, and the feedback from ECSA registration administration was that applications assessments were back on track. It was also pointed out by the administration manager of ECSA registration that training of assessors, moderators and reviewers that was scheduled for the first half of 2020 would have to happen going forward via online video conferencing. The other major consideration is that assessments and in particular the review stage/interview will need to take place as a VC. IC – Investigation Committee meeting 12thMay 2020 Investigations are ongoing and all I can say is that there are a number of LMI’s that are under investigation. Most of these are due to practicing out of scope of competence. EC – Education Committee meeting 15th May 2020 The greatest challenge for the EC committee is how to consider go about an assessment of engineering programs and approval of those engineering programs that would normally be carried as a site visit at the universities that would be now possible be carried out as an online assessment going forward if a physical site visit cannot be carried out. ECSA CoP – PoEW The Steering Committee and the Working Group that I am a member of finalised the overarching Code of Practice for the Performance of Engineering Work that was presented to ECSA council for approval scheduled for the 11th
June 2020. The next step will be for each sector of engineering to develop a Code of Practice for that sector of engineering for registered persons. https://www.ecsa.co.za/ news/Latest%20News/ECSA%20 Code%20of%20Practice%20for%20 the%20Performance%20of%20 Engineering%20Work.aspx ECSA Council meeting 11th June 2020 Besides all the high impact committees’ chairpersons each reporting to council one the work carried out for noting and council approval the main focuses of this council meeting was the nominations process carried out for the approval by the minister for Built Environment of the council members for next term of council. One of the plans that ECSA council will deal with in the next term is the determination of education standards and the accreditation of educational programs and set accreditation criteria, for institutions and create pathways for Academies and TVET Colleges programs for seamless integration into mainstream engineering qualification disciplines. This would be a pathway for the LMI qualification.The Engineering Council through the Council for the Built Environment (CBE) has developed a survey to feed into information required by the Women Empowerment and Gender Equality Transformation Committee. ECSA has requested that the members of Voluntary Associations – i.e. LEEASA are kindly requested to fill in the survey on the link provided below: https://docs.google.com/forms/d/ e/1FAIpQLScBGvTdfPkwvGRuEAGx pTXF9JRzqkZsILQbogMpnAz2YugQ uQ/viewform?usp=sf_link Until next time stay safe and take care, From Chairman, Arni Sommer.
As times of uncertainty prevail amidst a global health pandemic, Piet Otto CEO of Phakamisa Safety Consultants shares his opinions and trends of the lifting market. 1. Tell us a little about yourself and your professional background I have been involved with the lifting equipment industry since 1969 when I joined Mc Kinnon Chain in Port Elizabeth, after doing articles with a legal firm for four years. In 1999 I formed Phakamisa Safety Consultants after we sold the company to Haggie and last year celebrated my 50th year in the industry. I have been involved with marketing, manufacturing, inspection and testing of lifting equipment, mainly lifting tackle and hoists. I am a registered ECSA LMI, serve on SABS TC 1020, and a Council member of LEEASA.
lot of users do not understand and appreciate the importance of proper inspection, testing and maintenance of their equipment, they dis regard the importance of using properly qualified and equipped service providers and award contracts or services based on the lowest price offered. Another concern is the lack of understanding and legal requirements of lifting equipment issues by engineering and safety staff. These persons often impose their own opinions and requirements for the use, marking, certification, inspection and testing of lifting equipment.
2. How has your business been impacted by the current crisis and how are you navigating it to remain competitive in the market? Our business, which consists of training lifting equipment users and inspectors, on site auditing clients operations, and consulting has come to an absolute stand still with no income generated since the 19th of March. As it is uncertain as to when we will be able to assist our clients again, we cannot plan, other than to investigate possible online training in future. Due to the nature of our training, online training will not be easy and not very practical. We are however looking at all our training options.
4. What are the trends in the sector that you are seeing? What do you attribute it to? Since the introduction of LME and LMI requirements by the DOL for testing and inspection, there has often been a lot of abuse by some of these parties, for financial gain only, and taking short cuts at the expense of the user. All services must be conducted in accordance with the applicable Standards and the Law. As there is a shortage of LME/LMI services, mainly in smaller and outlying areas, users often take whatever is offered to them by the service provider as gospel and allow sub standard or unnecessary work to be performed. These trends are exacerbated by lack of passion for their work, financial gain, in experience and lack of knowledge and legal requirements by some service providers.
3. What are the biggest challenges facing the lifting sector today? Lifting is an essential service required in all aspects of mining, construction, marine and other industries. The use if inferior, and sub standard imported cranes, hoists and lifting tackle does pose a serious risk to health and safety. Failure can lead to loss of life and damage to property and equipment. Furthermore, as a

industries. Economists are not positive about our short or long term growth, mainly as a result of the Governments debt burden and al the other negative issues facing the country. Also local manufacturing will suffer for various reasons including the demands of the trade unions, lack of productivity and other issues such as the demise of Eskom, Transnet, municipal and other institutions that use a lot of lifting equipment. Our role is to train not only the user, but also the service provider to implement and maintain a safe lifting program in the work place. This will always be required, but the demand will depend on outside circumstances. 6. Do you have any key lessons learned during these trying times that you can share with our readers? It is hard to stay positive when your future is not in your own hands but is affected by the powers to be that dictate how, or when, you are allowed to operate. I have learned that online training and other options need to be pursued, but in a service industry like our it is not easy, as physical presence is required to assist the user to satisfy his demands and his requirements.

Education before registration As the past chairman of LEEASA, a recognised VA and an ex-councillor at ECSA, I need to bring to the attention of the department that there are serious problems regarding the competency of the LMI’s being registered at ECSA. This is being debated on the various WhatsApp groups with no solution to resolve the predicament. The solution exists and has been ignored. Who am I to make a judgment of this nature? Because of my background of 20 plus years in the hydraulic industry, I had been exposed to many lifting problems. Having been in the lifting industry for over 30 years, I have fixed, redesigned and modified equipment to function properly. A list of categories for which LMI's should be registered for has been submitted and include tackle, chain blocks, forklifts, mobile cranes, overhead cranes, tower cranes, ship cranes, wharf side cranes, reach stackers, straddle carriers, container cranes, aerial platforms, suspended access platforms, industrial lifting devices, under the hook non fixed devices, tail lifters and vehicle hoists. It now remains the responsibility of the new assessors contributing at ECSA to revise this. The dominating areas that influence the lifting industry are mechanical, structural, electrical/ 8

electronic and hydraulics. I recently did a presentation at the DoEL on hydraulics and they were amazed to find out that hydraulics influences all of these except for tackle. 1. The OHS Act states very clearly that an LMI and or an LTI should be competent. The definition of the competent person is quite clear as indicated in the definitions of the DMR regulations. 2. ECSA has always had an issue with specified categories when it comes to education because ECSA recognises NQF5 as the benchmark. The tertiary education sector is very well represented at ECSA including representation of our universities. However, it has always been thrown in our faces that our sector does not have a qualification which is incorrect. 3. When we started our specified category for LMI’s, we wrote a level 5 qualification which was registered with SAQA at the time. This was motivated by the DoL who engaged with the merSeta. 4. Registered level 5 qualifications used by the tertiary educators are compiled on the outcome-based system only and do not have
assessment criteria to underpin the outcomes. As a result of this, our group was tasked to redo the qualification and include assessment criteria. This we did and one year later we had done 9 unit standards to cover our range of equipment. 5. When we were finished we submitted these unit standards to SAQA for registration only to learn that the QCTO had been established and that these unit standards had to be registered by the QCTO which opening it’s doors in 3 months. This never happened in 3 months but only started 3 to 4 years later. 6. At this point, ECSA then re-did our qualification based on simply elaborating on what we had already done.This group of documents has included some other disciplines,
7. The complaints and concerns from our industry are that we are not educating our candidates before registration and we continue to use the alternative route which is not producing the desired results. Any profession has a compulsory requirement of education before registration. Why not us?? 8. Most of our candidates come from trades and the missing competencies are achievable at level NQF 4. These courses are presented by many registered and accredited training centres presented by qualified and registered facilitators, assessors and moderators. 9. So where do we go from here? The solution is simple. Recognise these facilities and stop the alternative route as the only route. (the alternative route should only be used in very exceptional cases.)
10. The benefits of this system are that the accredited training providers are audited and the structure is formal. 11. We all know that ECSA is not allowed to audit individual training providers registered at the Setas, but if training providers allow LEEASA subject matter experts who serve on the SABS, to audit the content of the learning material to meet the technical requirements as defined in our SANS standards. 12. All this is possible through bilateral agreements. There are enough ethical registered training providers who are willing to get involved in short notice.We also have qualified facilitators, assessors and moderators ready to get involved. I believe that any reputable professional wants to be audited to maintain the correct standards. 13. There are subject matter experts who serve on various SANS committees who will be willing to get involved. What are we waiting for?
In light of the Pandemic, this progress can still take place because the need for LMI's is still growing and has not reached a saturation point yet. The president has indicated that the government will be driving the economy by improving services. This will mean the construction industry, in which many lifting machines are used. Therefore LMI's will be in demand. Our industry is crying out for this type of progress. Although I have retired from the formal process at ECSA I am still actively training and offering registered CPD courses to LMI’s through LMI Academy. Reg. LMI. 2007120003.

COMPANY PROFILE
Trends in the Lifting Market from Emil Berning, Managing Director of Konecranes and Demag (Pty) Ltd 1. Tell us a little about yourself and your professional background After qualifying with a BSc Mech Eng degree, I started my career as a Design Engineer in the Automotive sector specialising in heavy vehicle transmissions and drive trains. This experience led to a Development Manager role leading a project team in off road specialised military vehicle platforms. Prior to joining Konecranes and Demag in 2018, I spent 17 years in senior roles in varied hydraulic and automation businesses involved in virtually all industries and geographical areas throughout Africa. I am currently Managing Director of Konecranes and Demag (Pty) Ltd, the South African legal entity and Business Area head for New Equipment and Service 2. How has your business been impacted by the current crisis and how are you navigating it to remain competitive in the market? Fortunately we have loyal clients and a strong order book in our Equipment business that once lockdown was lifted we were able to ramp up to fairly quickly. In our Service business, while we did see a dip during the level 5 and 4 lockdown period due to lower customer activity this has bounced back quickly as they ramp up again. Konecranes, being a Finnish company combined with the Demag acquisition in 2017 has been the forefront of technology in particular with our digitalisation approach which allows the management of customer assets; connecting data, machines and people to deliver a digitally-enabled customer experience in real time. We further offer remote monitoring solutions that continuously gather condition, usage and operating data and issues safety alerts. This allows customers especially during
the Covid-19 pandemic to limit the number of people required on site while ensure their lifting equipment is running safely and optimally. 3. What are the biggest challenges facing the lifting sector today? In South Africa, the current pandemic will continue to cause disruptions for many business for months to come. The economic outlook and recovery over the next few years is going to challenge many companies in our sector to maintain a high level of service and value add to the end customers. Those companies with strong international backing, high code of ethics support by cashflow and ability to scale their technology for customer benefits should survive and come out stronger from this crisis. On the product side and in a particular quality we see over recent years, an increase in the amount of lifting equipment being manufactured in far Eastern countries and imported into South Africa. Many of these products claim to have mechanism groupings based on the EN (European Norm) standard which all European sourced lifting equipment has to conform by. Buyers of this equipment should challenge their suppliers and ask to see the EN certification which the equipment claims has met the standard. Buyers can then make an informed decision on the quality of lifting equipment they are investing in. 4. What are the trends in the sector that you are seeing? What do you attribute it to? We have seen an increased focus on safety and productivity over the past few years and this should continue to the remain the highest priority for all users of lifting
Emil Berning, Managing Director of Konecranes and Demag (Pty) Ltd equipment. Coupled with this, customers are expecting transparency, speed and real-time feedback in the service with a higher emphasis on planned maintenance and oversight inspections to improve up time versus a reactive breakdown approach. A consultative approach together with their lifting suppliers can help guide customers in their decision making and we encourage users to take a holistic view of asset management and predictive maintenance especially the advance in digital tools and consider a real time feedback cycle of “data, insights, actions�. As this cycle repeats over time, maintenance predictions be-come faster and more precise. Price sensitivity during pre and post Covid-19 lockdown with the local economic situation has been extremely challenging. Pricing becomes a key factor in these trying times however buyers need to consider that the short term gain on the lowest price may be greatly negated by the impact on the reliability of the lifting equipment purchased and the potential consequential loss of production over the lifespan of equipment. With the financial constraints many
The common themes are increasing speed and lifting capacity, applying new safety features and positioning capabilities, or simply replacing high-maintenance, obsolete components with newer technology. 5. What is your outlook for lifting in South Africa? What is the role of your company in this out-look? We are cautiously optimistic and in the short term expect to face continued volatility challenges as many of the projects planned in South and sub-Saharan Africa may be delayed or placed on hold. The drive for localisation in line with governments intent on revitalising the manufacturing sector as well the expectations of the mining charter place an emphasis on companies to embrace getting on board with these programs. Konecranes and Demag (Pty) Ltd is
well placed to support localisation and job creation through exploring partnering initiatives with SMME’s. While we do see investment in automotive, manufacturing, mining and ports sectors picking up in the medium term, new technologies in lifting equipment and the approach to service activities has the potential to play a significant role in these investment decisions. Konecranes and Demag (Pty) Ltd as one of the world leaders introducing new technologies into the lifting equipment and service space is expected to continue setting the benchmark in the overhead industrial crane arena. Just two examples; the recent launch of our S-Series hoist using synthetic rope provided improved strength and durability over a traditional wire rope; and digitalisation of our service business with the yourKonecranes web portal providing customers real time view of their asset’s status. 6. Do you have any key lessons learned during these trying times
that you can share with our readers? Number one is do all that you can to keep your people and their families safe and minimise the spread of the infection to mitigate business disruption. Ensure you have robust processes in place to support this and everyone in the organisation understands and knows their role. A personal lesson learned and applied during these period is continuous and relevant communication both to internal and external stakeholders, especially with the level of uncertainty that exists. Other important attributes during these trying time is be adaptable and build flexibility into your organisation to help survive and cope with the constantly changing situation.

Explosion-proof hoists for Kusile coal conveyors
Condra has completed manufacture of eight explosion-proof, high-lift hoists – four of them articulated – for Tenova Bateman. All are custom-built, twospeed machines that utilise the modularity of Condra’s K Series to deliver performance capabilities precisely tailored to the individual requirements of each application. After commissioning at Kusile Power Station, the eight machines will carry out installation and maintenance work on coal conveyors. They will further boost Condra’s already substantial presence at Kusile, where the majority of overhead cranes and hoists have been supplied by this company.
capability quite quickly because of the modularity of the K-Series,” he said. “We can adapt the K-Series to an extremely wide range of requirements.” Condra is generally acknowledged as sub-Saharan Africa’s leader in high-lift cranes and hoists, a reputation which probably worked in favour of securing the Tenova Bateman order. Local manufacture would also have been a factor; there is increasing awareness that local sourcing will be one of the anchors upon which economic recovery in South Africa will rely.
Lifting capacities, lifting speeds and lift heights vary greatly among the eight hoists. Loads of between one and seven tons will be managed by fixed lifting speeds ranging from 1,25 to 12 metres per minute, and by lift heights of between 10 metres and 41 metres. Noteworthy among the machine features is the articulation on four of them, allowing travel around curves away from the line of conveyor movement.
Fully covered hoists provide lifting capacities to 32 tons, while opendrum units have capacities in excess of 250 tons. Features on all models include electromagnetic DC disc brakes, standard frame-size motors with parallel rotors, double-acting limit switches, solid bronze rope guides and totally enclosed splashlubricated gearboxes. Condra uses silumin rotor cores to enhance K-Series motor-starting torque in the high-lift role, and offers optional variable speed control on the drives to enable precise load positioning even on lifts of 100 metres and more.
Also unusual are the higher than normal lift heights on six of the units: 17 metres (two machines), 18.5, 21, 32, and 41 metres. A Condra spokesman explained that even the 10 and 11,5-metre lift heights of the remaining two hoists can be looked upon as high-lift. “Hoist with this sort of lift height are not off-the-shelf deliveries for most crane companies, but we can offer and deliver a high-lift 12
Lifting Africa - May/Jun 2020
The modular design of the K-Series allows rapid modification to specific high-lift application requirements (including lift speeds as quick as 1 metre per second – fifteen times faster than the 4 metres per minute found in many standard applications), resulting in delivery
times that are usually the shortest available. Standard hoist speeds go up to 18 metres per minute. After delivery, the hoists for Tenova Bateman will be installed in the coal silos and at various maintenance stations along Kusile’s conveyor route, where they will help with the installation, removal and maintenance of motors, gearboxes, rollers, pulleys and the conveyors themselves. All have been flame-proofed to IP65 standard, and explosion-proofed to Class II Zone 21 specification, countering the combustible nature of coal dust which can explode if sparked. Among other things, the proofing involved fitting special gland seals between the motors and the hoists themselves, and sealing all covers and panels. Articulated crawls have been fitted with modified cross-heads and assemblies that allow them to negotiate bends in the supporting I beams, which follow curved routes to take the hoists and their loads away from the conveyor line. Brass bushes on the articulation prevent any possibility of sparking. During manufacture, all welds were inspected at every stage, and all eight machines were completed with a special anti-corrosive paint specification.

OZ Lifting Products LLC has added the 2-ton (4,000-lb.) capacity OZ4000EC to its range of electric chain hoists. The manufacturer has steadily expanded the series and has launched the 227 kg (500-lb.) capacity OZ500EC in 2018. The 453 kg (1,000-lb.) capacity OZ1000EC and 907 kg (2,000-lb.) capacity OZ2000EC followed before the latest model was introduced as the only product in the range with two chain falls. The EC (electric chain) series is used in a variety of light-duty commercial and industrial applications. The hoists are predominantly used in general machine shop fabrication, assembly, storage and warehousing facilities. They are stocked at OZ Lifting’s Winona, Minnesota-based facility, where they are also tested, but supplied through a network of industrial equipment distributors in North America and overseas. Steve Napieralski, president at OZ Lifting, said: “We now cover the breadth of the electric chain hoist market in terms of capacity, and offer a quality unit at a competitive price. Expansion of the range
thusly strengthens our position in the market and gives existing and prospective customers double the capacity at their disposal at the top end of our portfolio.” Napieralski explained that two falls in the OZ4000EC allow the body of the hoist to remain smaller and more lightweight; its net weight is only 38 kg (84 lbs.), while the OZ500EC, OZ1000EC and OZ2000EC weigh in at 8 kg (18 lbs.), 24 kg (53 lbs.) and 24 kg (59 lbs.) respectively. He also pointed to standout features including overload protection and the dual braking system. The die-cast aluminium housing, meanwhile, contributes to portability. The product meets CE standards and H3 duty cycle rating, meaning it fits in the light/medium usage range. While OZ can rig custom chain lengths depending on the end user's requirements, Napieralski stressed that this particular range isn’t targeted at harsh or special environments, which are better
served by other products. Additional features of the EC range to note are the forged carbon steel load hook with a heavy-duty latch; a load sheave that provides better distribution of the load and smooth lifting with reduced vibration and wear; grade 80 alloy steel chain; and durable vinyl chain bag, as standard. Napieralski added: “We have steadily gained electric chain hoist market share and we have received positive feedback. “The COVID-19 pandemic has put us in a situation no one expected. It has affected nearly every market and product in some way. We are taking the appropriate measures here at our facility to protect our employees and business partners; we are pleased to continue serving our customers in the way that they are accustomed.”

A crane can only be as good as the sum of its parts Manitowoc’s Product Verification Centers have helped the company design and manufacture the most reliable cranes to ever be produced. The rigorous testing of component performance and working life cycles gives Manitowoc engineers insight into the anticipated performance of Manitowoc, Grove, National Crane and Potain cranes in the field. This process performance also speeds up product development for new designs, reduces warranty claims and on-site stoppages, and enables the direct comparison of supplier components. The Product Verification Centers test component designs earlier in the product development process than previously possible. That means component suppliers can be vetted before the products are placed in cranes. The head start enables Manitowoc to discover any potential difficulties at an earlier stage and work closely with component suppliers to devise solutions long before equipment reaches job sites. Barry Pennypacker, president and CEO of The Manitowoc Company, said that the testing processes at the Product Verification Centers have helped the company deliver on the promise of The Manitowoc Way. “The Manitowoc Way operating system has increased the velocity of our product development, so we 14

are able to bring new cranes to the market much faster,” he said. “The testing performed at the Product Verification Centers ensures that the cranes we are producing are reliable down to the component level, and this gives us the utmost confidence in introducing new cranes. We know that our cranes bring a level of quality to the job site not previously seen in the lifting industry.” A look inside At each Product Verification Center, there are specially trained staff, with dozens of managers, technicians and engineers contributing to the processes. A proprietary verification management system organizes, prioritizes, summarizes, compares and archives the centers’ test results. Manitowoc then shares its results with its suppliers, further strengthening its relationship with these companies, and also providing valuable insight that can help them improve their component production. The Product Verification Centers feature a number of technologies that deliver detailed pictures of anticipated component
performance. Among the most significant are: • Severe environment test (HALT) chambers that can mimic extreme temperature swings and test component reaction to continuous vibration • Walk-in temperature and humidity chambers that are large enough to fit entire crane cabs, consoles and power boxes • Structural test systems with stateof-the-art data acquisition systems • Electrical and software testing labs • Imaging systems for forensic analysis, including a thermal imaging camera and microscopes • Materials lab with chemistry analysis and material strength equipment, flaw detector and hardness tester • Cyclic corrosion chambers that recreate saltwater exposure and corrosive conditions • Modular test benches for fatigue testing that improves engineering calculation models and accelerates time dedicated to new developments • Gantries that perform 24/24hr endurance tests on hoist mechanisms These facilities enable the testing of entire cranes, too. Engineers can
A look back Manitowoc has had a long history with component testing, beginning decades ago at its facilities in France and the U.S. The company discovered that many of its suppliers couldn’t test their own products and when they did, the measurements were often incomplete. Driven by the desire to understand as much as possible about each component that goes into a Manitowoc crane, the company decided it should create its own verification facility. It started planning for the first standalone Product Verification Center in 2009 as part of its commitment to continuous quality improvement. In 2012 Manitowoc opened its first official Product Verification Center at its Shady Grove factory in Pennsylvania. The facility was the first of its kind in the industry
and provided unprecedented component testing capabilities. The first Product Verification Center saw great success, providing immediate insight into Manitowoc’s crane design and production processes. The program was so successful that Manitowoc decided to expand the operation. Having monitored the success of our Product Verification Center in the United States, the company felt the time was right to expand the concept with additional facilities. With the continued focus on innovation and lean manufacturing, as well as bringing several industry-leading models to market, additional Product Verification Centers in multiple regions would expand the company’s capacity for component testing. In the ensuing years, Manitowoc opened Product Verification Centers in Wilhelmshaven, Germany, and then began overhauling and improving its original testing facilities in Charlieu, Lusigny and Zhangjiagang to bring them in line with the new Product Verification centers in the U.S. and
Germany. Teams of highly qualified engineering personnel ensure that the Product Verification Centers in all these countries seek to test supplier components and crane functions to the highest levels of scrutiny. These teams include experts in assembly, erection, welding, mechanical engineering, hydraulics, electronics, vibro-acoustics and more. “By rolling out our testing and verification processes to Product Verification Centers across the globe, we have been able to replicate our success in improving component quality while increasing the quality and durability of our products,” Pennypacker said. “It was the right move to strengthen our position in all of these countries, and it has helped us ensure our position as one of the world’s leading producers of cranes.”

The importance of ergonomics in commercial vehicle production
One hundred and twenty-seven crane bridges, as well as a wide variety of hoist units, manipulators and power screwdrivers, integrated into more than six kilometres of rails in four profile section sizes – that was the scope of the KBK Aluline system that an international Demag project team planned and installed recently. This extremely smooth-running system improves ergonomics for handling parts and is a key factor for optimised productivity throughout the entire vehicle assembly operation. The Volkswagen AG Polish plant was to manufacture the latest generation of its VW Crafter where more than 3,000 employees manufacture the vehicle and – in the integrated supplier park – many third-party components. The plant, which covers 220 hectares, is designed for an annual capacity of 100,000 light commercial vehicles and has generous workshops for the body line and vehicle assembly as well as a state-of-the-art paint line. Heavier parts than in car production On vehicles such as the Crafter, everything is slightly heavier and larger than in a car production line. For this reason, the handling of parts plays a much larger role. Since commercial vehicles are usually made in lower quantities than car volume models, but in larger numbers of variants, many steps in production cannot be fully automated. Due to the weight of the parts, many stations need to be served by manipulators, workplace 16
Lifting Africa - May/Jun 2020
cranes and other handling equipment. This applies throughout the entire final assembly process, which is divided up into seven production and pre-assembly sections. Parts for a number of variants are also sequenced, picked and staged in several “supermarkets”.
Demag KBK Aluline Provides Full Coverage Volkswagen’s planners decided in favour of Demag KBK Aluline as a universal system to be used throughout the assembly operation.
Assembly of the VW crafter is implemented in 155 takt cycles. Components are continuously retrieved from load carriers, lifted or assembled into orders, which requires the use of corresponding lifting and transport equipment to provide the best possible ergonomics for the workers at the individual workplaces. Emil Berning, Managing Director, Konecranes and Demag (Pty) Ltd, said “The well-being of workers in large plant environments is an important factor that we at Demag pay close attention to. Our machines have been ergonomically designed in order to ensure ergonomics on the factory floor enhance the worker’s plant experience while maintaining the highest level of safety throughout the production and assembly processes”.
The Demag KBK Aluline crane construction kit has delivered an optimum performance in the entire automotive industry for more than five decades all over the world. The Demag brand aluminium crane construction kit offers particularly smooth running characteristics and low rolling resistance. In combination with its light-weight design, these properties offer direct benefits to
“In South Africa, the Demag KBK Aluline system has been installed in a number of our automobile manufacturing plants such as BMW, Ford and Nissan in Gauteng as well as MBSA in East London in the Eastern Cape which featured a number of extending cranes on the KBK Aluline system which provided handling capability outside of the crane runway area," said Berning. On the Polish project, Demag technicians installed more than 6,000 metres of profile-section rails for cranes and crane runways. In total, they installed 127 crane bridges for single and double-girder suspension cranes as well as a wide variety of hoists, manipulators (equipped with lifting columns, pivot arms and balancers) and tools. For its hoist unit needs, the Demag DC range of chain hoists was selected, which are rated for load capacities between 125 and 315 kg and are used with 2 speeds or variable-speed control, depending on the application. “Every step of the manufacturing

every worker on a daily basis. The bright and modern appearance of the rail system also ideally matches the friendly workplace design of the new VW plant. Besides ergonomic aspects, there was a great emphasis on safety and serviceability. KBK Aluline meets both of these requirements in full due to Demag’s extensive international experience. In addition, the easily assembled and versatile modular system can be simply extended or converted so that processes and the material flow can be modified at any time.
process has different handling requirements – which can be met without exception with the KBK Aluline system. This is also applicable for different height levels and types suspension: if they are needed for the horizontal mobility of conventional crane installations that are equipped with chain hoists, suspensions that have articulated joints are used. Rugged ergo suspensions that can accommodate torque and kick-up forces are used for applications with handling equipment and telescoping power screwdrivers” added Berning. Regardless of the type of use case, KBK Aluline system rails always provide optimum load capacity for their given deadweight. Four profile-section sizes make it possible to choose the right solution for the
relevant application. The special plastic travel rollers provide for extremely smooth and quiet travel characteristics. This also ensures that only a little force is required to move them – for optimum ergonomics and a low physical load for the worker. Optional integrated conductor lines can eliminate the need for external power supply lines or unwanted trailing cables. The system's bright design, in combination with lighting systems, meet exacting specifications, enables each workstation to be ideally illuminated.

HEAVY LIFTING
Gantry lifting taken to the next level Enerpac Heavy Lifting Technology has boosted the capabilities of its gantry range enabling heavy lift contractors to tackle more demanding projects within the space constraints common to industrial moves. New gantry accessories include increased side shift options, skid track end stops, header beam sling guides and a power distribution unit for simpler power connectivity. Enerpac telescopic hydraulic gantries are a safe, efficient way to lift and position heavy loads in applications where traditional cranes will not fit and/or are too expensive to mobilise. Available in lifting capacities from 100 tons up to 1100 tons, the gantries provide accurate load positioning and are easy to mobilise and demobilise. Side Shifting Last year, modular electric powered, header beam side shift units were introduced for the entire telescopic gantry range from the SL100 through SBL1100. This year top swivel kits were added allowing additional header beams to be mounted on the top of side shift unit. This allows crossbeams to be installed for more complex lifting arrangements. The Enerpac powered side shift can also be used on other manufacturer’s gantry systems and fixed beam lifting and hoist systems by using a stand-alone electrical 18

When once round the world just isn’t enough Six Liebherr machines are in operation for the extention of the Deutsche Bahn. Even the high demands for the realization of this project cannot shake the new slurry wall package. Every day it rattles once round the earth and even further. The equivalent, at least. The distance covered by the suburban railway in Munich is staggering. It was opened for the Olympic Games in 1972 and has now reached its limits. The old lady will find her feet again thanks to the expansion of the rail network, Munich’s largest construction project for the coming years. To cope more efficiently with the bustling stream of passengers in the inner city the Deutsche Bahn is building a second core line between the stations Laim and Leuchtenbergring. A central entrance to the tunnel is in the Altstadt at Marienhof. Here the joint venture VE 41 comprising Implenia and Hochtief is carrying out slurry wall work using Liebherr equipment. High demands The challenges lie in the large dimensions of the slurry walls and the extremely confined space on the construction site. Due to the partially historical buildings in the immediate surroundings, an application with low vibration is necessary for the installation of the slurry walls. But at the same time, it must also meet the high demands for compactness and verticality. The contractor found the correct equipment in the brand-new 24
Lifting Africa - May/Jun 2020
Liebherr slurry wall cutter type LSC 8-18 L. The cutter’s high weight, high cutter frame and low centre of gravity provide the optimum basis to achieve the necessary verticality. Maximum process safety is achieved through the full integration of the verticality measurement in the Liebherr control system. Furthermore, 12 independently controllable steering flaps can correct the cutting direction should any possible deviations occur. The actual position of the flaps is displayed in real-time on the monitor in the operator's cab. To deal with the confined spaces of urban construction sites, the cutter can be positioned over the bite using a continuous hydraulic turning device. The new equipment from Liebherr cuts its way through 33 m3 of soil per hour and requires 8 hours for a primary trench. A total of 108 trenches measuring 1500 x 3200 mm with 30 cm overlap must be installed on the construction site in Munich. In addition to the cutter, the hydraulic slurry wall grab, type HSG 5-18, is in operation. It is also fitted with verticality measurement and a turning device for the frame and is mainly used for the initial excavation of the trenches.
Complete Package The carrier machine for both the grab and the cutter is a duty cycle crawler crane type HS 8130. Its excellent stability in combination with the largely dimensioned winches make the HS 8130 the perfect basis for such heavy equipment. The joint venture is using the separation plant SPC 600 C, which Liebherr offers as part of a complete package for slurry wall applications. The package also includes grab, cutter and duty cycle crawler crane. The plant can process up to 600 m3 support fluid including excavation material per hour. In addition to the two duty cycle crawler cranes with slurry wall cutter and grab respectively, the drilling rigs type LB 24 and LB 44 are also working on the cramped site for the expansion of the suburban line. Further, the crawler crane type LR 1250 lifts the reinforcement cages into place, each of which weighs up to 55 tons and is 55 metres high. The second core line is scheduled to open in 2028. Then the Munich Lady can rattle her way along even more tracks than before. Because once round the world isn’t enough.

The gamechanger in crawler cranes Ideal in tight spots
The PALFINGER crawler crane PCC 57.002 manoeuvres well in limited space, can shift (or "walk") on its outriggers and can be operated electrically. It´s perfect for indoor jobs, such as the removal of escalators. Manoeuvring the PALFINGER crawler crane PCC 57.002 through the main entrance of an Austrian furniture store was delicate work. Thanks to its compact dimensions – just 1.9 metres wide by 2.1 metres high – and precision steering with the PALcom P7 radio remote control, the crawler crane easily navigated through the 2.2 metreshigh entry area. Once inside, the crane unfolded to its full size – just like a transformer. Its mission: the removal of two escalators. High Performance in the Tightest of Spots The PCC 57.002 is ideal for use in very restricted spaces. Its crane unit can be operated and controlled independently of its crawler chassis.
The crawler crane can also "shift" on its outriggers, enabling it to navigate low passageways, and always be optimally balanced and stabilized. Fewer Constraints All these features meant that the PCC 57.002 was a perfect choice. Without this crane, the two escalators would have been cut up – a noisy, dusty and timeconsuming process that would have restricted opening hours. "Especially in building construction, you are constantly faced with new challenges where you reach your limits and have to develop whole new concepts and solutions to achieve your objectives," says STRABAG construction technician
Michael Eisshofer. Electric and Emission-free Once inside the store, the unit was switched from diesel to electric mode and performed immediately. Thanks to the crane outreaches of twelve and seven meters, both escalators, each weighing five metric tons, were effortlessly removed. “We opted for the PALFINGER crawler crane because the building could be accessed only through a very, very narrow doorway, so it was the only solution,” says Eisshofer.

Manitowoc launched the new MLC150-1 crawler crane Manitowoc has unveiled its latest crawler crane the Manitowoc MLC1501. It is the latest in a line of crawler cranes that have been very successful, especially for their competitive load charts and job site manoeuvrability. The new crawler crane continues the momentum of its popular predecessor, the MLC100-1, increasing the capacity to 150 tons (165 USt) and adding a host of several new features. It was designed to meet the needs of customers that desire a compact, manoeuvrable crawler crane with a strong load chart and easy transport. “A big component of The Manitowoc Way is listening to exactly what our customers need and want in their cranes,” said Brennan Seeliger, product manager at Manitowoc Cranes. "We have had great feedback on the MLC100-1, so we based the new MLC150-1 on that model, but boosted the capacity for the 150ton (165 USt) class." The MLC150-1 features a 150-ton (165 USt) base capacity and a maximum boom length of 78 metres (256 ft). A fixed jib of 24 metres (80 ft) with a 27-ton (29.5 USt) capacity is available for the crane, and a 52-metre (170 ft) luffing jib with a capacity of 46-ton (50.2 USt) is another strong option for the job site. This new crane features quicker assembly than previous models, too. The boom butt mounted sheave enables self-assembly without the boom top, it features a button style rope termination, and a gantry-raised counterweight reduces components.The boom cap, jib butt and struts ship as a single package for fewer connections. It’s also easier to transport. An increased hook height enables self-assembly with various trailer 26

Additionally, the left side console rotates for improved egress inside the cab. "Users will like the
upgrades to the cab in the MLC1501," Seeliger said. “While this crane has great capacity and reaches for the 150 USt class, improved transport and erection efficiencies are always something users like to see.” In addition to the unveiling of the MLC150-1, CLT Cranes, +27 (0) 323 9600, info@craneloadtech.co.za, www.cltcranes.com

FORKLIFT
Lithium-ion outpacing battery power options The advent of Lithium-ion driven forklifts is revolutionising the materials handling industry. According to Masslift Africa, the companies who are willing to step into this new era will see numerous benefits around efficiency, runtime, and maintenance in comparison to the lead-acid battery predecessors. According to Hugh Golden, National Sales Manager, demand for Lithium-ion powered forklifts is on the rise. This is partly due to the numerous benefits associated with lithium-ion batteries and in part due to changes in legislation.
consider when looking at the costs of Lithium-ion versus lead-acid battery-powered forklifts. “Yes, Lithium-ion batteries are around 1.5 to 2 times the prices of lead-acid but you are getting a longer lifespan and saving on maintenance costs.”
availability and shifts. This also reduces the need for a second battery for night shifts if the battery is charged whenever the driver takes a break – for example during tea times, lunchtimes, shift changes, toilet breaks etc.”
“The demand in South Africa is growing annually. One reason is that legislation will inevitably move towards minimising the use of diesel forklifts around food products. We are also seeing several clients moving away from diesel or LPG (gas) forklifts due to the emissions and costs associated with LPG.”
Lead-acid batteries need to be maintained daily by topping up each cell with deionised water and cleaning the battery of spilt acid with a wet cloth to prevent tracking. Failure to top up the battery results in oxidation which damages the plates and decreases the battery lifespan. Additionally, numerous health safety risks can arise when the battery is not cleaned. The battery terminals can start to corrode which can cause the battery to catch fire. Acid also corrodes the tank and wiring which are costly to repair.
The operational benefits of not requiring a second battery for your night shifts include the fact that there is then no need for a battery bay which is costly to install and requires space, ventilation and epoxy painted floors.
Golden says that he anticipates a major increase in the demand for electric forklifts over the next 5 years – and that Lithium-ion will likely be the preferred choice over the more traditional leadacid batteries as it outperforms in several areas. When compared to lead-acid batteries, Lithiumion power offers superior energy efficiency, zero maintenance and longer life cycles for greater uptime and productivity. “Lithium-ion batteries have a longer lifespan lasting 6 to 8 years or 12,000 to 20,000 hours, and this is a battery that is completely maintenance-free throughout its life,” Golden explains. According to Golden, this is the main factor that clients need to 28 Lifting Africa - May/Jun 2020
By contrast, Lithium-ion batteries require zero maintenance throughout their lifespan. Lithium-ion also wins when it comes to charging and uptime. Lead-acid batteries must be charged for eight hours at a time and don’t allow for opportunity charging. “Lithium-ion allows for batteries to be charged anytime, for any period – even just for a couple of minutes,” Golden explains. “This allows much greater flexibility in your operations as you can even structure charging around driver
The charging cycle and focus on maintenance both affect the lifespan of batteries in the long term. As lead-acid batteries age, they don’t last as long between charges. To get as much productive time behind the wheel of the forklift as possible, most drivers will then push the battery as long as they can and will discharge it past the recommended ‘80% depth of discharge’. When this happens, a voltage spike can occur, damaging the forklift’s electronics which is expensive to repair. There are no voltage spikes with Lithium-ion batteries which goes a long way towards protecting and preserving the forklift’s electronics. Does this charging system translate to power and efficiency? “Yes,” says
The output power is the same, but Lithium-ion has been estimated to run for 1.35 times longer than a forklift powered by a lead-acid battery.” Golden explains that this difference between lead-acid and Lithium-ion in respect of power stems from the fact that as a leadacid battery discharges during operation, the speed of the forklift starts to reduce due to the drop in voltage. Because a Lithium-ion battery sustains a constant voltage during discharge, the performance of the machine is not affected. “In terms of efficiency, this makes Lithium-ion streaks ahead of the older lead-acid technology.” “In addressing safety, which remains a key concern from a driver and operational point of view, Lithium-ion batteries are seen as lower risk because they are maintenance-free. This takes human error in cleaning or topping up the battery incorrectly out of the equation. The main safety concern is the emission of harmful acidic gasses and hydrogen given off by leadacid batteries while charging. These gasses pose health and corrosion risks that you don’t worry about with Lithium-ion. Lead-acid
batteries can also be damaged by corrosion and cable failures because they contain sulfuric acidbased electrolytes,” says Golden. In looking to a greener future, Golden notes that lead-acid battery disposal poses a higher environmental risk due to the hazardous nature of the lead and the sulfuric acid. Lithium-ion batteries, by contrast, can be recycled into their base elements – lithium, iron and phosphorus. There is, therefore, no risk of acid spills that cause injury, or damage to properties or the environment. To date, Masslift has received over 50 orders for Lithium-ion electric forklifts. This has been on their Mitsubishi 3 and 4 wheel electric models (FB – TCB/ CB) which are all compatible with Lithium-ion batteries. Masslift Africa’s Mitsubishi RBF Reach Trucks are also compatible providing numerous options within the costeffective MLIFT range. “We do recommend that drivers charge the batteries as often as possible and make sure they don’t discharge the Lithium-ion battery down to 0% as this can damage the battery which affects the warranty,” Golden reports. Masslift is committed to guiding clients through the process of adopting this new technology. “We provide a detailed warranty
directly from the battery supplier to our clients. We are transparent when it comes to discussions around the pros and cons as well as performance and technical data. With this, we can show customers the total cost of ownership comparing the diesel, LPG, lead-acid and Lithium-ion options. As experts in this field, we also understand that each application is unique, and we strive to supply clients with the forklift that will be most beneficial to their specific needs and operations.” In closing, Golden emphasises that clients need to be ready to adapt to new technology to reap the benefits. “We think Lithium-ion is the future and we are saying, let’s be pioneers and go for it. The operational efficiencies and potential life span of the battery outweigh the risks of testing the new technology. Masslift will always be open to making available any product that can reduce total cost, extend the life of the forklift or make the forklift safer – and we’ll always be pushing these to the forefront where we feel our clients stand to benefit.”

LIFTING TACKLE
Lifting Equipment training, plant audits, registers and codes of practice There often appears to be a lot of confusion in industry and mining, including at major construction sites, regarding the legal requirements for the inspection and/or testing of lifting tackle (LT) and chain blocks and lever hoists, now defined as hand-powered lifting devices, in OHSA DMR 18 2015. It must be noted that the revised DMR 18, published by the DEL, effective October 1, 2015, placed new responsibilities on users and suppliers, with new lifting equipment definitions, user’s responsibilities and revised contents. The revised DMR also incorporates certain lifting equipment SANS documents, which now become mandatory under section 44(1) of the Act. Although LME and LMI requirements for mining operations are not specified in the MHSA Chapter 8 Regulations, these inspection and testing requirements, applicable to lifting machines and hoists, is accepted as compulsory for mines as well. Section 103 of the MHSA is relevant by interpretation. It is common knowledge that all lifting machines, which are classified according to different Codes in the DMRNCOP, must be performance load tested at intervals not exceeding 12 months, by a service provider or LME, which is a company registered with the DEL. The actual load test on the lifting machine, including hand, powered
34
Lifting Africa - May/Jun 2020
lifting devices, but excluding lifting tackle, must be conducted or be supervised by an LMI, who is registered with ECSA. The LMI would have been assessed and found competent by a Registration Committee at ECSA, to test only the specific types of machine for which he has been registered for, as an LMI. Note that ECSA does not print the scope of competence of the LMI on his LMI certificate and the only method for the user to establish whether the LMI is competent to load test a specific category of machine, is to request a copy of the LMIs ECSA letter of registration, which reflects his scope. Here are some of the frequentlyasked questions around this issue 1. Visual Inspections compared to Examinations. It is the writer’s interpretation that a visual external inspection is done by visually checking all visible components of a sling or hoist, by a proper checklist. This inspection can be done by a competent person who is defined in DMR 18 as a “person or inspector, appointed in writing, with the necessary training, knowledge and experience relevant
to the type of lifting tackle or hoist that he is inspecting “ An examination is a “detailed study by a competent person in such depth and detail as he considers necessary to enable him /her to determine whether the equipment being examined is safe to remain in use” (SANS 500) This examination could include stripping and repairing of a hoist and then conducting an operational test on completion. Such an examination can be done by an LMI or appointed competent person such as a technician or artisan. 2. Must a lifting tackle inspector (LTI) be a registered LMI? The answer is no. It must be stressed that an LTI does not have to be a registered LMI. The core function of an LMI is to conduct or supervise a load test on a lifting machine or hoist. LMIs are qualified to inspect lifting tackle as well, providing they have also had the necessary training and experience. Government notice No: GRN 257, dated March 7, 2008 states “This registration does not apply to persons who examine lifting tackles in terms of regulation 18 (10) (e) of
3. Who can inspect lifting tackle? Lifting tackle has to be visually inspected, at intervals not exceeding three months, by a “competent person”. The person is deemed competent by his "knowledge, experience and training" and appointed in writing as an LTI. The LTI should keep a register of these inspections on site. It must be noted that inspections can be conducted at more frequent intervals if so required by the user. No specific inspection periods are specified in the MHSA, Chapter 8.5 Regulations and mines have to specify in their Standard Operating Procedures (SOP) their inspection periods, method, requirements, inspector qualifications etc. There is currently no DEL requirement to register LTI’s with the DEL, although this can be legislated in future. Lifting tackle inspections can be conducted by in house appointed LTI’s or contracted service providers, the latter obviously at a cost to the user. If the user is using a service provider to conduct lifting tackle and hoist inspections, the user should insist on the service provider’s staff providing proof of training and experience, and that they have been appointed, in writing, by the service provider.
as a test above the rated WLL can develop a latent defect in the sling that could cause it to fail later on, under repeated loading. For example, to subject a sling with a WLL of 5 ton, that is 5 years old, to a test load of 10-ton, which is equal to a 100% overload, can be detrimental or damaging to the sling, or certain components of the sling such as hooks and coupling links etc. (c) All OEMs specify a WLL for the size and type of sling supplied, and state that the sling must not be subjected to a load over the rated WLL. This WLL is also specified in the relevant Standard, such as a SANS, to which the sling or product is manufactured. (d) It is also relevant to take cognizance of OHSA Section 15 “Duty not to interfere with, damage or miss-use things” when load testing slings in use to more than the rated WLL of the sling as this can damage the sling. (e) To test a 2-ton webbing sling to 4-ton proves nothing as the sling should not fail at a load of less than
14 ton if it conforms to SANS 94, which specifies a FOS of 7:1 Even an inferior, sub-standard 2-ton sling should withstand a proof load of 4 tons but does not confirm that the sling is legal in terms of SANS 94 which requires a minimum 14-ton break load. (f) All testing of new lifting tackle must be conducted under an "accepted or appropriate technical standard” There is no SANS or International Standard for load testing slings in use. There are only standards for the OEM to test new slings or components as part of his manufacturing process. For the above reasons, testing of slings in use is therefore not encouraged. Only lifting machines, including hand, powered lifting devices, must be periodically load tested by LME/LMIs. 5. What type of certificates must be supplied with LT and hoists? The word “Test Certificate” does not appear in the OHSA or MHSA. It is common practice, and the user should insist that suppliers provide either a Certificates of Test
4. Must lifting tackle in use be subjected to annual load testing? The answer is an emphatic NO Over the last few years, this practice has become popular, mostly as a result of the user's ignorance of legal requirements and service providers who promote this practice for commercial reasons. It must be stated that manufacturers of the chain, wire rope and webbing, are totally against this practice as: (a) It is not a legal requirement in terms of OHSA DMR 18 (10) or any MHSA Chapter 8 Regulations to conduct periodic load testing on slings in use. (b) It can be detrimental to the service life of a sling or component Lifting Africa - May/Jun 2020

or a Certificate of Conformance to a specific quality manufacturing Standard, when purchasing lifting tackle and hoists. A Certificate of Test must state the actual test load, the date of the test and other relevant details as specified in the relevant Standard, whereas a Certificate of Conformance must state the Standard, such as a SANS, DIN or EN to which the product has been manufactured. This certificate is regarded as the “birth certificate” of the sling and must be kept on record till the sling is scrapped, after which the certificate can be cancelled as the equipment as it is no longer in use and has been removed from the workplace. Slings must be marked with the relevant certificate number, and rated WLL, and other details for traceability back to the supplier. The rule of thumb is “where does it come from and what can it lift?” If a sling is not marked with this information, do not use it! It is also important thas users have a written scrapping procedure that specifies the steps to take when scrapping LT, which must include cancelling the suppliers' certificate, as the sling is no longer in service. 6. Must slings be colour coded periodically? This is not a legal requirement but can be stipulated in a company SOP. There is no international Standard
for colour coding either. The practise is to attach a specific colour to a sling or hoist after it has been periodically inspected. It is important to note that a sling is not always safe to use, simply because it is colour coded, and operators should be trained accordingly. Proper colour coding charts must be placed in the workplace in conspicuous places etc. 7. Must sling hooks be fitted with safety latches? This is also not a legal requirement but, once again can be insisted upon in a company SOP. Certain hooks, such as foundry hooks and grab hooks are not designed to be fitted with latches and these hooks fully comply with international quality standards such as EN 1677. Note that top and bottom hooks fitted to chain blocks and lever hoists must be fitted with latches, as required in SANS 1594 and SANS 1636. 8. Must sling and hoist hooks be pop marked? This practice is also not a legal requirement for sling hooks but recommended for crane hooks. Sling hooks can be damaged as a result of incorrect methods of marking and the manufacturer will dispute any subsequent claim for damage etc. See OHSA Section 15 “duty not to interfere with or damage….” Also, pop marks should be applied by the supplier before first use.
The relevant SANS for chain blocks and lever hoists specify that the OEM “shall supply a means or information for the user to determine if the hook throat opening is more than the OEMs specification" This "means or information" can be in the form of marks on the hooks applied by the OEM, or the dimensions can be specified in the operating manual which must be supplied with the hoist. Any hoist that carries a CE mark must be supplied with an EU Declaration of Conformity, a Test Certificate as well as an operating manual and be branded according to CE requirements. The manual will specify hook throat openings. 9. What marking should be on Shackles? Shackles do not have to be marked with an individual number. Shackles should be marked with the WLL, the size, a traceable OEM symbol or brand name, as well as with a batch compliance number or mark. Most shackles are marked in imperial sizes such as 5/8 or 3/4, as most shackles comply with US Federal Specs which are not in metric sizes. Shackles could also be stamped with a specific number of the corresponding supplier’s certificate, but this is not a legal requirement and must be done in an area recommended by the OEM. 10. WLL versus SWL, These terms are often confused and there is a difference. The WLL is the maximum load to be lifted, lowered or suspended by a hoist or sling as specified by the OEM and specified in the manufacturing Standard The WLL is marked on the hoist or sling tag and is based on the design factor (FOS) and must never be exceeded. All tackle and hoists manufacturing Standards specify that hoists and sling be marked with the WLL, and not the SWL. The SWL is determined by a competent person
36
Lifting Africa - May/Jun 2020
To name a few examples: (a) The SWL of a sling reduces as the angle increases between the sling legs and If a chain is used to lift hot loads, the SWL reduces as the chain temperature increases.
(b) If shackles are used at angles the SWL reduces accordingly (at 90° less 50%) (c) The SWL of a mobile crane is specified on the cranes' load chart that specifies the SWL depending on the boom angle and boom extension.
that the above information is the writer’s opinion only and should not be construed as legal advice or legally binding, but as a guide to promoting lifting equipment safety in the workplace.
Unfortunately, there are many grey areas in both the OHSA and MHSA regarding the use, inspection and testing of lifting equipment and discretion and best practice must be adhered to. Safety Officers and other supervisory personnel must be cautioned not to possibly insist on specific legal requirement if they do not know what the law requires. The law is there to be implemented by the user and not to be interpreted for personal or commercial purposes.Lastly properly compiled SOPs (written operating procedures) must specify all lifting equipment requirements, particular to the User’s specific operation and be implemented by their staff and contractors. To conclude, it must be stressed
Phakamisa Safety Consultants assist to compile customized SOPs, conduct audits and provide specialized lifting equipment training and consulting, with the objective for users to comply with a Total Safe Lifting Program in the workplace.

MINI CRANES
The first Jekko SPX532 SPX532, one of the latest but already appreciated Jekko mini cranes, arrived in Latin America for the first time and was recently delivered to Guindaste Aranha. The new model adds up to other Jekko mini cranes already owned by Guindaste Aranha, who has been Jekko products’ representative in Brazil for two years. This mini crane became known thanks to the important innovations it incorporates: a cutting-edge stabilising system, a sophisticated electronic and hydraulic system, greater ease of use, increased lifting capacity (3.2 tons), an updated design and a new and user-friendly radio remote control.
"Thanks to the compact dimensions and footprint, smaller than in the previous SPX527 and SPX536 models, and the excellent lifting capacity and maximum reachable height, SPX532 is positioned between the small size and the big size mini cranes and is the right answer to both rental and sale market needs," says Mr Jefferson
Important new features include also the 1-ton hydraulic jib, the maximum height of which, at 17.3 metres, can be compared to that of a higher category of crane. The jib can be stored in three ways, either at rest on the column, on the ground or resting under the main arm. SPX532 is the most highperformance single door crane on the market and can be used for work in both confined spaces, particularly in the glass market, and open areas in the industrial maintenance and building sectors. 38

SPREADER BEAMS
Airpes spreader beam for wind turbine manufacturer Airpes, a manufacturer of lifting, weighing and below-the-hook equipment, has shipped the first in a series of 75 metric ton capacity custom, adjustable spreader beams to one of the largest companies that assemble wind turbines. The beams are a new development of an old type that the customer bought from various suppliers. Airpes and the customer came together to address some safety and flexibility issues to arrive at the new design. Airpes has active sales with three of the top four wind turbine producers in the world. The beam weighs approx. 5 metric tons and measure approximately 10-metres (33 ft.); it was designed with flexibility in mind and will be utilized beneath the hooks of various overhead cranes and mobile cranes, which range in capacity from 100 tons to 400 tons. The beam will primarily be used to lift almost-finished product in the final stages of a manufacturing and assembly process that spans the U.S., India, and Germany. It will also be capable of lifting repower turbines in the field. The device has a three-way adjustable balance mechanism that allows flexibility for different operating environments and also to provide a safe back-up in case power is lost. The bale that rigs the beam to the hook can be shifted forward and aft, when unloaded, to 40

adjust for new types of loads with different weight distributions. It was manufactured at Airpes’s main factory near Barcelona, Spain. Tad Dunville, general manager at Airpes Americas, said: “The beam is designed for safety and flexibility. It can work under most reasonably similar cranes of that capacity and has features that allow it to quickly be moved from crane to crane and also refocus on somewhat different loads. They are one of our best customers for safe working procedures; the factory is very clean and efficient, and they have an impressive safety crew. I love working with them because they realize that not just the load is important, but so are the people and the time.” Airpes delivered a complete turnkey solution that included rigging gear. Dunville continued: “Our customers expect us to deliver a whole package.That means the ancillary features are no longer ancillary. If they have to hunt around for five days to find a shackle that we regularly buy, it doesn’t add value. Same with logistics and product support; we are quickly signing up partners in a support network
because our customers want a solid base to operate from.” Airpes has three principal lines of business, namely pre-engineered weighing and monitoring kits for overhead cranes, including load cells, overload protection, readouts, and data loggers; engineered lifting devices for wind turbine erection; and engineered below-the-hook devices, such as coil grabs, rotating blocks, and magnets (and lifting and spreader beams). As is the case with the majority of case studies, the latest order included product design, build and documentation. Dunville said: “There are very few manufacturers out there that have built any diesel-hydraulic spreaders; we rarely do not have one under production. Beyond that, we offered the best price, a very robust design, flexibility to work with automation, and a vibrant support network. We were also willing to train a few local providers as dealers and repair centres and that made a big difference. Nobody wants to know how smart we are, they want to know how quickly we can support them.” He added: “There always is [an

alternative, less technological solution], but we don’t want to be the bottom feeder—ever. We all know who those guys are, and they’re constantly creating problems for owners with inexpensive components that have no support network. That said, we always like to think
through some value engineering solutions with our crane builder partners. In this instance, we were once again able to save some serious money by re-thinking noncritical pieces.” •Reading Crane, Shaw-Box, Buckner Heavylift Cranes and Barnhart Crane are among other companies that
will interface with the adjustable beams. Buckner and Barnhart, both mobile crane and rigging firms, could utilize the product in the field, Airpes stated.

WATER BAGS
Proof load test water bags
The age-old question within the lifting industry is the use of solid weights VS proof load test water bags. While there is use for both solid weights & water bags in the industry depending on the applications and site requirements, water bags are the more economical option when it comes to the inspection and load testing of larger lifting machinery. Some machines such as forklifts are only suited to testing with a solid test weight as the machine's load centre needs to be achieved and the test load cannot be under-slung as per SANS 10388. While there is use for both solid weights & water bags in the industry depending on the applications and site requirements - water bags are the more economical option. So the debate begins. Test weights or proof load test water bags? Cost-saving It is far more economical to transport water bags as opposed to solid test weights provided the application is right. As mentioned – forklifts and certain other machinery cannot be tested with water bags. If we look at the practicality with regards to the transportation – water bags make more sense. As a frame of reference to transport 70 tons of solid test weights will likely require three trucks and the logistical cost on that is astronomical, whereas the transportation of 70 tons of water bags is simple - 2x correctly rolled 42

35-ton proof load test bags can be transported on a 1-ton light delivery vehicle or bakkie as we put it in South Africa. This means that we can achieve more competitive pricing as the logistic cost is lowered.
water will keep flowing and the load will increase – however the reading on the flow meter will not. If we look at Europe – Flow meters are no longer permitted to be used as there have been multiple incidents that have occurred whilst in use.
Going green. Now we know to be more conscious than ever when it comes to environmental issues and water saving methods. So how do we combat this?Simple – most sites have water treatment systems and we can pump the water back into the system to avoid wastage.
The function of a load cell is to measure mass or load and is, therefore, more suited to the application of load testing. One must remember it is essential for a load cell to be calibrated regularly to ensure accuracy.
With regards to port applications – seawater can be pumped from the port – provided the right pumps are used and the seawater is drained straight back into the ocean. Use of flow meters VS load cells While a flow meter is a cheaper option - one must take into account the function of a flow meter, which is to measure flow and not mass. Many factors could affect the reading of the flow meter for load test use. One factor is the viscosity of the water – basically the water density. Are you using clean water, dirty water or seawater? All factors play a role in the mass that will be applied. Now a flow meter only measures flow and not water density and therefore cannot be considered accurate. Another factor that could affect the reading of the flow meter is if the water is not clean and an object becomes jammed – such as a stone – the
Now let's talk price. The cost of water bags are very high as the materials used must be of the highest quality.The investment in water bags requires a lot of capital to procure these bags and the life spans depend on care, handling, frequency of use and material construction. Regular maintenance is also essential. It is not economical for some companies to purchase bags due to the capital required, however -there are a few companies such as ours - that offer water bag rentals and will gladly assist throughout Africa with rental solutions to suit the project. The rigging of Load Test bags. LMI's & LME's making use of load test bags must know how to rig them. It is also essential to note that the way bags are rigged could effect tonnage capacities if multiple bags are rigged together. The way bags are rigged could
WATER BAGS
also affect the loss of water on the ground and drainage of the bags. As a rule of thumb when calculating how many bags need to be used on larger tests – we often allow for +/- 10% in loss of capacity per bag – provided the bags are rigged correctly. Not shock loading. Use of water bags also avoids the machine being shock loaded and avoids damaging the machine further should the crane have a failure. This is because the load is increased in increments by filling water the LMI can monitor the machine as the load is increased – if any defection is detected the LMI can stop filling the bag and drain to avoid failure. This safety aspect is essential – as it avoids further damage to the lifting machine and machinery surrounding the machine. Quality and material construction of proof load test bags are essential as they are required to simulate large load tonnages, and any failure due to poor quality products could result in catastrophic failure onsite in which you are working and this risk must be nullified. How do we do this? By ensuring that the bags which are used are of the highest quality and conform to international standards. Multiple incidents have occurred within South Africa and around the world as a result of using bags that are of inferior quality. A few years back an incident occurred within South Africa and an investigation was carried out by CSIR. CSIR documented every aspect of the material construction did a comparison between the bag that failed and a European proof load test bag from our company. It was found that the material construction was far inferior on the failing bag - and the material construction in terms of thickness was documented as 0,6mm, the mass/unit area was documented at 880g/m2, tensile strength was documented at 3000/3200*N, further to this puncture tolerance was found to not have any tolerance.
CSIR found the material used to be suitable for industrial tarpaulins. We have also seen this on some other imported bags. The material is also of much inferior quality and often the slings used for the harnesses are not lifting slings but rather a sort of lashing material.
QUALITY PROOF LOAD TEST BAGS IS ESSENTIAL Just as a comparison – our bag that was also subjected to the testing at CSIR – it was documented that the thickness of the bag was 1,3mm thick, the mass/unit area was 1650/m2, tensile strength was 8300/9800*N, further to this our bag was found to have a puncture tolerance. This means that if the bag is punctured – the bag will not split and water will just come out from the puncture – but will not drop an entire load of water onto the floor. The CSIR found the material used to be suitable for airlift bags for which
they were originally designed and suitable material for proof load test bags. The standards that should be adhered to are as follows when looking at proof load test bags – EN ISO 1421, DIN 53357, DIN 53358, DIN EN 12127, DIN EN 1876. Other quality assurance testing that should be done are tests such as drop tests whereby certificates are issued to assure the quality of the bag.Most European bags come with this certification. This essentially means - the bag is filled within its rated capacity and a drop test is conducted – to put this into perspective because the force of the drop test on a 20-ton proof load test water bag is simulated to 44 tons – this test is conducted on every bag before it is sent out and not one per batch – this test is done only on commissioning. This is essential to ensuring the quality of the bags. In conclusion, it is more economical to use proof load test bags to test lifting machinery provided the application permit this. We also strongly advise the use of load cells with the use of water bags rather than a flow meter.
