EDITOR'S COMMENT

THE ‘DRAGON’ IS GAINING GROUND

O nce dismissed as low-end pabilities and now compete head-to-head with multinational companies on their home turf as well as in emerging markets such as Africa. Indeed, China has driven the growth of machinery production worldwide in recent years. To provide context, three Chinese manufacturers now rank among the top 10 construction equipment makers in the world, according to the 2021 Yellow Table – an annual ranking of construction equipment firms. XCMG and SANY ranked third and fourth respectively, ahead of global heavyweights such as Volvo Construction upstarts, many would agree that Chinese construction equipment makers have built up their ca-

Equipment, Hitachi and Liebherr. All man- ufacturers that moved up in the ranking list are from China, showing the vigor- ous development of Chinese equipment manufacturers. The most impressive was Zoomlion, which moved five places from 10 th to fifth position. In fact, having produced and delivered 100 000 excavators in 2020, SANY has for the first time become the number one ex- cavator manufacturer in the world (by vol- ume). The ascent of the ‘dragon’ has been fuelled in part by the rise of the middle market in rapidly developing economies, where customers have boosted demand for ‘good enough’ products that empha- sise price competitiveness and sufficient functionality rather than customisation and the most advanced technologies. These products occupy the middle ground between the low-cost products that have been a mainstay of Chinese cost innovators and the premium products typ- ically offered by leading multinationals. Demand for good-enough products is also increasing in developed markets such as Europe and North America, as companies seek to reduce supply chain costs in the face of persistent economic uncertainty. Chinese companies are adding to their competitive strengths by building skills that go beyond cost advantages. In research and development, this means gaining access to advanced technology through either aggressive investments or acqui- sition of companies that have developed cutting-edge capabilities over the years. To reach upper-end customer segments and accelerate brand development, some Chinese companies have acquired a competitor with a premium brand. Using a dual-brand strategy, the acquiring company keeps both the premium and the low-cost brands in the market, each serving specific price segments. For example, China’s Sany Heavy Industry acquired a majority stake in Putzmeister, a leading German manufacturer of high-tech concrete pumps. SANY remains focused on operations in China, while Putzmeis- ter continues as a premium brand. The

acquisition also gave SANY access to Putzmeister’s innovative pump technology. Elsewhere, in 2008, Zoomlion acquired CIFA, one of the world’s biggest concrete machinery manufacturers, in a transaction recorded as the largest ever European acqui- sition by a Chinese company at the time. With this approach, Chinese challeng- ers will continue to build momentum. In this new competitive landscape, European companies can expect to see their tradi- tional advantages diminish in areas such as advanced technology, brand strength, quality and reliability, as well as familiari- ty with customers. China’s increasing prominence in the local market is especially noteworthy. Brands such as LiuGong, SANY, XCMG and FAW (on the commercial vehicle side of things), are making their mark in the local market. For example, the SANY brand has grown in leaps and bounds in the past four years under the dealership of Goscor Earthmoving in South Africa. At the start of 2020, SANY ranked 9 th in the South African excavator market, before moving to 5 th position by the end of the year. LiuGong has enjoyed great success in the mining sector, with the brand making sig- nificant headway into both hard and soft rock mining segments in recent years. FAW has gained a strong foothold in the local commercial vehicle market. The company recently saw its 7 000 th locally assembled vehicle rolling out of its Coega manufacturing plant. This marked another significant milestone for the Chinese brand that took the top spot in the Heavy Commercial Vehicle segment of the local market for the first time in the first quarter of this year and to date maintains this achievement by outselling various well-known and established brands. The rise of Chinese challengers in the capital equipment sector will persist over the long term. Chinese companies will continue to invest heavily in R&D, expand their offerings of high-value products and pursue aggressive acquisition strategies to gain access to technology, brands and markets. b

QUICK TAKE

Scania fuel efficiency – every drop counts The increased focus on cost is influencing fleet owners to look closely at fuel efficiency when making those buying decisions. For LTD Transport, a Gauteng- based dry bulk tanker specialist, fuel efficiency is a fundamental area of consideration, a principal reason it has bolstered its fleet with 25 Scania New Truck Generation R560 models, writes Munesu Shoko .

Founded some 26 years ago, LTD Transport currently operates a modern fleet of 70+ vehicles, including 8 and 12 tonners, tri-axles, flat decks, tautliners, box side tippers and dry bulk tankers

John Deere is expanding its construction line-up to 18 countries across southern Africa and West Africa. LTD Transport has upgraded its fleet with 25 NTG R560 units.

For its dry bulk tanker business, the company is largely running Scania units. The company recently purchased 25 NTG R560 models following the range’s grand launch in 2019

Given that fuel accounts for 35 – 36% of its running costs, fuel efficiency is a primary factor in LTD Transport’s buying decisions

Vehicle data recorded from multiple Scania trucks, in daily operation, using multiple drivers, have yielded an average 10% fuel saving across the NTG range

challenges including rising operating costs, increased fuel prices, decreasing revenues and tighter margins. To put it bluntly, the economic and operational effects of the pandemic on the trucking industry have been challenging and devastating. Industry experts warn that the

true storm for the trucking sector may not be over yet, and the effects witnessed to date may be warning signs of what’s yet to come. In such a tough trading environment, fleet owners are looking at every opportunity to cut their operating costs, and fuel economy is central to that approach. Given that fuel

accounts for up to 36% of its running costs, dry bulk tanker specialist LTD Transport does not compromise when it comes to its fleet’s fuel efficiency. For this reason, the company has over the past 15 years continued to grow its Scania fleet, and the arrival of the New

COVER STORY

The Scania R560 is powered by a 16-litre V8 Scania engine delivering 560 hp.

LTD Transport has been running Scania trucks for the past 15 years.

Truck Generation (NTG), which has set new benchmarks in total cost of ownership, providing customers with sustainable cost- efficiencies, has further boosted savings through unprecedented fuel economy. Going the Scania route Founded some 26 years ago by Duard Pretorius and his wife, the family-owned business currently operates a modern fleet of 70+ vehicles, including 8 and 12-tonners, tri-axles, flat decks, tautliners, box side tippers and dry bulk tankers. For its dry bulk tanker business, the company is largely running Scania units. The company bought its first Scania R480 units some 15 years ago and never looked back. According to Pretorius, LTD Transport recently purchased 25 NTG R560 models following the grand launch in 2019. A dry bulk tanker operation is no easy task; it demands a vehicle with power – lots of power. The NTG R560 strikes a healthy balance between power, productivity and fuel efficiency, three key parameters that have influenced the company’s decision to standardise its entire fleet with this

powerful model. The Scania R560 is powered by a

“Since the launch of our NTG range in 2019, our customers have seen at least 5% more fuel efficiency. What’s important is the fact that you don’t just order a new truck; you order the right truck, for the right application – a notion which Scania very much shares. Understanding my clients’ application and topography is essential in ordering the right truck that performs with the best fuel efficiency, which is what we have done with LTD Transport,” says Charles. This, he adds, coupled with Scania’s Driver Scoring (Scania FIT Report), which can be tracked by both Scania and the client, indicates where the driver needs to pay attention. “We have had instances where a driver would score a 92% average, but had a bad rating on coasting or idling, which impacts fuel consumption and efficiency,” explains Charles. For years, Scania has been championing its operating economy approach with great results for fleet owners. There are three cornerstones of operating economy: the driver, the vehicle and the services behind it. These are all areas of focus with the

16-litre V8 Scania engine delivering 560 hp, allowing the truck to discharge more than enough power to master this tough application. For Pretorius, however, it is the fuel efficiency that matters most. “Fuel is in fact the biggest consideration when we make our buying decisions. Bear in mind that fuel accounts for 35 – 36% of our running costs,” says Pretorius. “We recently switched to the NTG R560 after its local launch in 2019 and the fuel economy has been superb. We are, on average, achieving 2,8 litres per kilometre, which for a V8 is unheard of.” Neil Charles, sales representative at Scania Southern Africa, says given that fuel costs can equate to over a third of transport companies’ total operating costs, the proven fuel saving on Scania’s NTG range boosts profitability for transport operators. “The SA transport industry has seen a diverted market over the past year, with clients opting to change lanes as fuel consumption continues to become a fundamental tool in preparing and costing their rates,” he says.

a fleet, has the potential to remove significant expenditure from operators’ total running costs, boosting profitability and significantly improving their ability to compete in a highly competitive market. “Across industries, we know that maintenance costs absorb much-needed revenue and profit. The NTG has the potential to pay for its own maintenance,” says Erasmus. It’s total cost of ownership has been redefined, and Scania South Africa sees it as a game-changer that will help customers such as LTD Transport find a sustainable revenue increase while their competitors continue to struggle with high operating costs. “As challenging economic realities bite, Scania’s sustainable cost efficiencies are driving our customers’ business ambitions and delivering increased profitability, so helping them achieve otherwise elusive business growth,” adds Erasmus. Support matters A good product is one thing, but being able to offer unparalleled aftersales support to keep the wheels turning is quite another. Another key factor in LTD Transport’s decision to opt for Scania is the whole service experience, all the way from sales and financing, through to insurance and aftersales. For all these services, there is a single point of contact at Scania Southern Africa. Scania Fleet Management Services have also proven worthwhile for LTD Transport. The technology allows the company to make decisions based on facts. The key to operational efficiency lies in the ability to transform real-time operational and logistical data into valuable, actionable information which impacts the entire business. With Scania’s fleet management portal, fleet owners are able to monitor vehicle performance, fuel consumption, loading and unloading, driver behaviour, safety follow-ups and route planning – helping them improve efficiency and reducing overall maintenance costs. From an aftersales support perspective, Scania’s wide branch network is key to keeping truckers on the road. The quick response times in case of breakdowns help reduce truck downtime. To keep its customers’ productivity high and their fuel expenditure low, Scania constantly strives to improve its trucks and services. By constantly refining the three cornerstones of fuel economy – vehicle, driver and services – the OEM is able to help transport operators such as LTD Transport thrive in the face of difficult operating conditions. b

new NTG R560. From a driver perspective, the new R560 offers greater driver comfort, which is another key feature at the centre of increased productivity. Based on Scania’s understanding that a comfortable driver is a productive one, the R560 comes with a spacious cab. Customers can opt for either a double bunker or a single sleeper, offering class-leading comfort, visibility and control. Great savings At a time when the trucking industry is facing increasing demands for sustainable and cost-effective operation, Scania’s NTG is setting new benchmarks in total cost of ownership, providing customers with sustainable cost-efficiencies, and securing a competitive advantage in their industries. Technological developments are behind Scania’s latest sustainable operating breakthrough. Vehicle data recorded from multiple Scania trucks, in daily operation, using multiple drivers, have yielded an average 10% fuel saving across the NTG range.

Central to the range’s unparalleled fuel efficiency are improved powertrains and better aerodynamics. Every Scania is equipped with smart technology, advanced sensors and wireless connectivity. Scania Southern Africa has thousands of constantly connected vehicles providing the data needed to make informed cost saving decisions. The proven 10% fuel saving compared to the Scania PGR range, is said to make the Scania NTG the most fuel-efficient truck in South Africa. “Fuel costs can equate to over a third of operators’ total operating costs,” says Mark Erasmus, GM Sales, Scania Southern Africa. “Any improvement in fuel efficiency can provide drastic savings.” However, he says, Scania isn’t resting on its laurels. “The highest recorded fuel savings in the market provide our customers with the cost savings needed to offset maintenance costs. By using the fuel savings, our customers can pay zero maintenance costs,” explains Erasmus.

The T40.180SLP forms part of the 12-model Bobcat R-Series range introduced in May this year.

Expanded telehandler range from Bobcat As part of its ‘Next is Now’ campaign, Bobcat has rolled out an expanded range of telescopic handlers. With an extended range and increased investment in this business segment, the company aims to double production of telehandlers by 2025, writes Munesu Shoko .

A recent report by 360 Research Reports notes that the global telehandler market, which generated a market value of US$4,5-billion in 2020, is anticipated to rise at a considerable rate between 2021 and 2026. In 2021, the market is growing at a steady rate and with the increased adoption of growth strategies by key players, it is expected to rise over the projected horizon. Bobcat – one of the key players in this market segment – plans to double its telehandler production by 2025 in line with anticipated market growth. The plan has been put in motion with the recent launch of an extended range of telehandlers. Inspired by the company’s ‘Next is Now’ philosophy, Bobcat in December last year announced the collaboration with Magni TH of Italy, to launch an expanded line of new generation rotary telehandlers for markets in Europe, the Middle East and Africa (EMEA), as well as Russia and the CIS countries. This was followed by another big launch in May this year, which saw the introduction of the company’s new generation R-Series telehandler range for the Middle East, Africa, Russia and CIS markets.

Rotary telehandler range The new Bobcat rotary telehandler range developed in conjunction with Magni TH includes 10 Stage V compliant models for the European market, with lifting heights from 18 to 39 m and lifting capacities from 4 to 7 t. These are complemented by four Stage IIIA engine powered models aimed at the Middle East, Africa and Russia/CIS regions, with lifting heights from 18 to 25 m and lifting capacities from 4 to 6 t. The new R-Series range for MEA and Russia/ CIS comprises the TR40.180, TR50.210, TR60.210 and TR60.250 models. The new rotary telehandler range, says Olivier Traccucci, Bobcat telehandler senior product manager, offers an expanded model selection and increased lifting heights and capacities. The new range offers cutting- edge technology that continues the theme of reinvention that is at the core of the company’s ‘Next is Now’ philosophy. “As a result, they offer enhanced 360° performance to create the ultimate tools for even the most complex site handling jobs. A big choice of over 20 attachments and various options also ensures that working at height has never been so versatile, efficient, comfortable and safe,” says Traccucci. Available since December 2020, the new

rotary telehandler range from Bobcat was introduced at an online launch event held on December 2, 2020. This was a continuation of the Next is Now strategy presented for the first time in EMEA and Russia/CIS at a previous online event in October 2020, where Bobcat launched 48 products in 12 different categories. Growing market The rotary telehandler market continues to grow worldwide. In Europe, for example, the market has increased over the past five years by 23% and, in 2019, it reached over 3 000 units for the first time. In fact, the EMEA region accounts for 85% of the global market. Invented in the early 1990s, rotary telehandlers feature a rotating turret and four stabilisers, which enable them to work solidly in place with full operating capacity. The 360° turret rotation allows the machines to handle loads everywhere in the working envelop without needing to move. This is an ideal solution in urban areas where space is at a premium. Their ability to work from a single point to cover the whole site and the fact that they can be used from the first to the last day of a construction project have made

interior of the cab features stand-out R-Series branding, colours and textures that clearly reflect Bobcat’s DNA. All surfaces in the cab have been optimised to offer increased space and visibility. The cab is based around a new 5-inch LCD display providing interactive and streamlined information, including the feed from the rear camera for easier and more precise operation. Uptime is key in construction. Bobcat telehandlers have always had a tough design and the new R-Series models build on this reputation, thanks to the protective shielding of all vital components in key areas, and the robust frame and boom for working in every possible environment. The shielded design provides protection for hydraulic and electrical components (including the pipes, harness and transmission) and a steel plate protects the base of the machine. All Bobcat telehandlers have a rigid boom structure and a robust frame with box section layout. All areas of the R-Series range are designed to inspire full confidence in customers, beginning with the low centre of gravity and well-balanced design of the machines, which also incorporate a heavy counterweight and a long wheelbase. The optimum weight distribution of the new Bobcat telehandlers, with or without the compact stabilisers being employed, also allows operators to safely reach high lifting capacities with heavy loads. Under the bonnet, the proven Perkins Stage IIIA engine provides high power, while the simplicity of its mechanical injection system ensures ease of service. In addition, all R-Series telehandlers now feature a new engine hood with a steeper profile that increases visibility and reduces blind spots by 15% on the right hand side of the machines. Together with the new dashboard design, this provides unobstructed visibility from the cab, allowing the driver to move around the job site with ease. “As with all new Bobcat telehandlers, the R-Series offers customers peace of mind with a standard 3-year/ 3 000-hour factory warranty on the entire machine. Bobcat is the only manufacturer to provide a 3-year warranty as standard, allowing customers to focus entirely on growing their business without worrying about their machines. And with regards to the cab interior, we are now the leaders in the field. As we have constantly involved our customers in their design, we are confident that the new generation machines will be well received in the marketplace,” concludes Quentin D’Hérouël, product manager Telehandlers at Doosan Bobcat. b

With the new R-Series, Bobcat wants to further improve its presence and accelerate its growth in the MEA construction and rental market.

“Telehandlers are a fundamental asset of our business strategy and a key pillar of our Next is Now initiative. With these new models and the increased investment in our telehandler business, we aim to double production of Bobcat telehandlers by 2025.”

2,6 and 4,1 t. This is the latest phase in Bobcat’s revolutionary ‘Next is Now’ programme, combining innovative product development and diversification with more intelligent, user-friendly technologies that reshape how work gets done. Commenting on the R-Series launch, Gustavo Otero, president, Doosan Bobcat EMEA, says: “Telehandlers are a fundamental asset of our business strategy and a key pillar of our Next is Now initiative. Our new ground-breaking R-Series offers high performance, robust machines for maximum uptime with a focus on accurate controls and intuitive operation for tackling any job on the construction site. With these new models and the increased investment in our telehandler business, we are aiming to double production of Bobcat telehandlers by 2025.” The new R-Series range of telehandlers from Bobcat comprises the following models: compact telescopic loaders (TL26.60, TL30.60 and TL30.70); middle range telehandlers (TL35.70, T35.105, T35.105L and T36.120SL); and high-lift telehandlers (T35.130S, T35.130SLP, T35.140S, T41.140SLP and T40.180SLP). “Bobcat telehandlers are popular in MEA and with the new generation, we

want to further improve our presence and accelerate our growth in the region’s construction and rental markets. Leveraging the ease of use, safety and reliability of our equipment, we aim to be present on every job site, where this kind of equipment is needed,” adds Otero. Benefits abound The new R-Series telehandlers offer agility on demand, with a newly configured transmission system providing enhanced smoothness to carry out the trickiest jobs at height with ‘surgical precision’. These operations are also facilitated by the combination of the Boom Positioning System, the new updated, accurate joystick, the inching function and the improved visibility from the cab. An enhanced, ease-to-use inching pedal design reduces operator fatigue, thus maximising productivity. A higher engine brake provides a shorter stop distance and increases safety on construction sites. Turtle/rabbit speeds are standard on all models and operated using the joystick.

Space on urban construction sites is becoming increasingly limited, and with the new MT 930 H, Manitou is responding to strong demand from rentals and dealers for compact machines.

New segments in Manitou’s construction range

Rough-terrain handling, aerial work platform and earthmoving company Manitou Group has unveiled new segments in its construction range with new compact fixed, ultra-compact telehandlers and articulated loaders. This is complemented by a complete overhaul and extension of its range of rotating telehandlers. By Mark Botha .

T o bring clarity to its range of our entire range by making it simpler,” says Manitou Group MRT product manager Carlo Alberto Razzoli. “By modernising the design and ergonomics of our products, we are now able to offer a single cab across all the models in the range, so providing excellent visibility to users, whatever the model.” Having the same cab also means having an equivalent control station on all models, making them quicker to get to grips with. Two new machines, the MRT 1645 and MRT 1845 telehandlers for the Vision range, have been added to this offering. With 500 kg of additional load capacity compared to their predecessors, these products offer lifting heights of 16 and 18 m respectively rotating telehandlers, the group has named its two ranges Vision and Vision+. “We are seeking to harmonise

for a load of 4,5 tonnes (t). The models are also equipped with a new Stage V engine, producing 75 and 116 hp respectively. The Vision range offers a selection of 14 models with heights ranging from 16 to 25 m and a load capacity up to 4,5 t. Razzoli says the highest capacities are grouped together in the Vision+ range, which features 12 models. The range has been revamped with six new products: MRT 2260; MRT 2660; MRT 3570 (also available in an electronic suspension version); MRT 2570 and MRT 3060. With models offering lifting heights of 22 to 35 m, and an improved capacity of up to 7 t, this range is ideal for the installation of structural steelwork, renovation of buildings and even demolition. The two ranges are connected as standard to optimise maintenance, increase

the machine’s operating hours and thus reduce the total cost of ownership for the user. The Vision and Vision+ ranges are now available worldwide and will be delivered by September this year. When asked what motivated the decision to establish new telehandler segments, Razzoli points to the growing demand among customers wanting machines that offer higher performance on construction sites. He says the new models will be available in Africa as of the beginning of Q3 this year.

Innovative equipment He says the Vision name was also chosen to convey the idea of in-cab visibility. “To increase visibility further, a reinforced gridless roof certified to ROPS/FOPS level 2, is available as an option for closely monitoring loading operations at height.” The pressurised cab on all Vision and Vision+ models provides a healthy working environment and additional sound insulation for greater operator comfort. Another innovation is an optional driving remote control for controlling the machine from the basket or for when the operator is outside the machine. As a result, it is possible to move it safely without having to return to the driver’s cab. A hydraulic pump is fitted on all the new models. With a hydraulic flow of 116 l per minute, the Vision range ensures an execution speed 50% quicker for simultaneous boom movements. The improvement provides a 30% quicker execution speed on the 2260 and 2660 models in the Vision+ range, which are equipped with a pump that delivers a flow rate of 185 l /min. The new Stage V engine, which provides power of between 156 and 211 hp depending on the model, also helps to reduce consumption on these models. “The lifting capacities and load charts have been significantly improved, most notably the capacity at maximum height, improved by up to 100% and, at maximum reach, by up to 25%,” says Razzoli. He says the weight of these machines has been reduced by more than 5% while benefiting from an increase in their load capacity of up to 15%. Safety and ergonomics A pack of five LED headlamps ensures full lighting around the machine. Two additional boom head work-lights provide good visibility during loading operations at height. A rear camera which sends images to the cab allows the machine to be manoeuvred with confidence. Four accesses built into the chassis enable the operator to climb into and out of the machine regardless of the cab’s rotation. The new 8” vertical touchscreen on the Vision range and available in a 12,1” XXL version on the Vision+ range, provides a human-machine interface. Both ranges also feature hydrostatic transmission offering greater driving flexibility and giving the operator a maximum speed of 40 km/h. The latest addition to the Vision+ range, the MRT 3570, allows the operator to carry out handling operations of up to 35 m. For increased visibility at this height, the group has introduced a new electric seat that tilts

MATERIALS HANDLING

Low cost of ownership To lower total cost of ownership (TCO), users of the new range have the option to analyse their hydraulic oil by means of two caps under the boom. This simplifies oil collection, maintenance and reconditioning or dialysis of the hydraulic oil. TCO is further reduced by an optional Stop & Start solution which automatically cuts out the engine when idling. It can be configured from one to 30 minutes, and turns the engine back on when the accelerator pedal is depressed, or via movement of the JSM, without having to restart. The fuel savings are significant, with a maximum of 45% idle over the entire usage time. Construction site safety The three telehandlers can be equipped with the company’s optional Safety Pack, which supports and protects the operator and their environment. It warns on-site teams of movements by the machine with its boom raised, for instance. To avoid inadvertent machine movement, the JSM now detects the operator’s hand to carry out hydraulic movements. A reversing aid informs the operator of people behind the telehandler. Access to the cab is also optimised for risk-free entry and exit. An automatic parking brake with hill-start assist also helps reduce the risk of accidents. Ultra-compact fixed telehandlers The group will launch ultra-compact, rough-terrain telehandlers with a height of 1,9 m and a width of 1,49 m towards the end of 2021. These ultra-light Manitou (ULM) models weigh just 2 700 kg with standard attachment, and can be transported on a standard trailer with no permit required. Revamped articulated loaders Manitou Group is revamping and extending its range of articulated loaders. The machines feature a new design, accompanied by numerous options. Innovations include a reduced width for moving around rough-terrain sites more easily and an optimised hydrostatic transmission for enhanced comfort. The four compact models, MLA 2; MLA 3; MLA 4 and MLA 5, will be connected and equipped with a short arm for greater capacity and a long arm for applications calling for increased lifting height. They will also be available with canopy or integral cab. These new models will be distributed within the dealer network, to renters and key accounts by the end of 2021. b

by up to 18°, to monitor deployment of the boom. This model is also available in an electronic suspension version. Manitou Group will offer a fully-electric extension to the Vision+ range by the end of the year, as well as a hybrid version combining a smaller engine with a lithium-ion battery. Compact fixed telehandlers Manitou is creating a new segment with compact and hydrostatic fixed telehandlers. With three new models, the MT 730 H, the MT 930 H, and the MT 930 HA (with platform basket), the company is responding to strong demand from rentals and dealers for compact machines, with space on urban construction sites becoming increasingly limited. These compact sizes (2 x 2 m), have a broad selection of equipment. In the cab, the intuitive Harmony screen gives the operator real-time maintenance and usage notifications. These three models are easy to transport and can therefore be delivered quickly from site to site. A fork mounting system on the carriage further optimises the length of the machine with attachment, so reducing transport costs. These machines feature hydrostatic transmission and a 75 hp engine to guarantee precise, flexible movements.

RIGID DUMP TRUCKS

With Trolley Assist, onboard pantographs connect the truck’s drive system to overhead power lines on uphill haulage segments.

Diesel-electric technology on dump trucks: the way forward? In the quest for zero-emission mine sites, reduced carbon footprints and improved margins through fuel conservation, dump truck owners are on the lookout for alternative ways to power their equipment, prompting Liebherr and other OEMs to introduce diesel-electric technology on their trucks. By Mark Botha .

A recent study by Interact Analysis on the global off- highway vehicle market, including the market for diesel-electric haulers and dump trucks over 85 tonne (t) capacity, has found that the 1 330 diesel-electric haulers and dump trucks delivered in 2020 will increase to some 1 545 units this year, and rise to a total of 1 783 units sold annually by 2029. Liebherr-Africa mining director Tom Munch says the growing interest in diesel- electric technology in rigid dump trucks is driven in part by the need to reduce CO 2 in mining. “As mining customers around the world show greater interest in reducing CO 2 emissions, innovative solutions such as electrical drive systems will be

enablers for the zero-emission mine sites of the future.” He says Liebherr’s “20 years-plus” of success in this field stems largely from the company’s vertically integrated Litronic Plus AC power drive system which, when combined with a powerful diesel engine, yields higher speeds on grade while enabling trucks to haul more material in less time. “The Litronic Plus drive system uses maximum available engine power to deliver smooth acceleration and consistent speeds on grade, leading to reduced load spillage,” says Munch. Diesel-electric technology Developed and built by Liebherr, the Litronic Plus diesel-electric AC drive system maximises power conversion into mechanical torque. The diesel engine and traction alternator generate AC power, which is then converted into DC power to supply a common DC Bus. “Insulated-gate bipolar transistor (IGBT) frequency convertors transform the power back to an AC waveform, which drives each of the rear wheels and traction motors,” says Munch. “The IGBT frequency convertors enable continuous variable-speed control of the traction motor, from zero to maximum speed.” By extracting optimal power from the diesel engine, the drive system makes more power available for acceleration on inclines, while conserving fuel. “The Litronic Plus system optimises electrical, mechanical and hydraulic power distribution while minimising fuel consumption when the engine is idling. This also reduces CO 2 emissions,” says Munch. “Our goal is to use as much of the

truck’s load-carrying capacity as possible for payload.” Advantages The advantages of diesel-electric drive systems over traditional mechanical drive technology include reduced maintenance costs and lower total oil consumption. “The reduced cost of the additional cooling system for downhill, loaded

operations also results in less service time,” says Munch. “With the IGBT system, the drive system power components are liquid cooled to maintain optimum component temperatures. This leads to maximum reliability and reduced maintenance requirements.” Diesel-electric products Liebherr offers a full range of diesel-

With this system, onboard pantographs connect the truck’s drive system to overhead power lines on uphill haulage segments to translate the full power capacity of the electric wheel motors into speed on grade while the diesel engine idles. In 2013, Liebherr received an initial request from Canadian mining and metals company First Quantum Minerals Limited (FQML) for a 360 t trolley-capable haul truck for use at a future mine site in Panama. The truck would be required to integrate with the trolley power line that FQML had designed and developed for the site. Agreeing to this partnership, two Liebherr T 284 trucks were commissioned, tested, calibrated, verified, and evaluated in Zambia. “The trial period was determined a success, leading to an official order for 30 more trolley-assisted trucks for what is today the world’s largest copper mine, FQML’s Cobre Panama in central South America.” The trial was in fact so successful that the customer ordered six additional trolley-capable RDTs for the Sentinel Mine in Zambia, bringing the total number of T 284 trucks running on the Liebherr Trolley Assist System to 38. development contract for a trolley assist system for the VA Erzberg iron ore mine at Eisenerz, Austria. “The T 236 uses the trolley system with its active front-end technology to reduce fuel consumption significantly while in trolley mode,” says Munch. “VA Erzberg anticipates a reduction in fleet fuel consumption of approximately 3-million l of diesel, as well as a reduction in annual carbon emissions of 4 200 t.” The future Munch says Liebherr strives for long-term sustainable solutions, and investigates different options focused on safety, cost, reliability, maintainability and flexibility. “We offer a full range of electric excavators, and the full mining truck product range will soon be trolley- capable. We have a clear vision and roadmap to achieve low fossil fuel solutions by 2022, and fossil fuel-free solutions for the majority of applications by 2030.” He says a study has found that the 1 330 diesel-electric haulers and dump trucks delivered in 2020 will increase to some 1 545 units this year, and rise to a total of 1 783 units sold annually by 2029. b T 236 Trolley Assist At bauma 2019, Liebherr signed a

electric off-highway trucks (OHTs), including the T 236, available with 100 t load capacity; the 240 t T 264; the T 274 (305 t) and the T 284, available in 375 t capacities. All of these are powered by the company’s proprietary Litronic Plus AC drive system. Trolley Assist “In order to reduce operating costs and carbon emissions even further, we offer the Trolley Assist system for our truck ranges,” says Munch “The Liebherr Trolley Assist system improves productivity, lowers fuel consumption and reduces emissions. This is the first step on the road to a zero-emission mine site.” The T 274 is based on the proven design of the Liebherr T 284, which has gained more than 20-million operating hours in the field. The frame and components are shared between both the T 284 and the T 274. Liebherr’s solid reputation as a reliable OEM stems from consistent development and production of high-quality mining components, products, and services. The T 274’s mining-optimised components are developed, manufactured, and controlled by Liebherr following the company’s vertical integration model to ensure top performance and reliability for the entire machine. Liebherr T 274 – the new 305 t mining truck Liebherr is extending its product offering with the T 274, a class-leading 305 t haul truck. The new truck bridges the gap between the highly successful T 284 (363 t) and the upgraded T 264 (240 t). Designed and adapted from years of experience in mining truck development, the T 274 is a true 305 t machine that provides fast cycle times, higher production rates, low fuel consumption and a low cost per tonne. The new truck follows the same base design as the T 284, benefitting from decades of field experience. The Liebherr T 274 is powered by the most powerful engine in its class at 3 650 hp, and the efficient Liebherr Litronic Plus AC Drive system. With the advanced hydraulic design and fast cycle times, the T 274 moves more material in less time. The new addition to Liebherr’s mining product range is said to offer a truck with the largest payload capacity in its class, moving more tonnes each hauling cycle. Speed on grade is a major contributor to fast cycle times. The Liebherr Litronic Plus AC Drive System improves cycle time efficiency by providing continuous uphill speed, differing from traditional mechanical drive trucks that require shifting of gears. Designed with safety in mind, the T 274 is equipped with 4 500 kW / 6 035 hp dynamic braking power to operate efficiently on downhill hauls. Pairing the Liebherr T 274 with the Liebherr R 9800 hydraulic excavator provides the customer with a highly versatile and productive fleet. The fast swing times of the R 9800 will load the T 274 with four bucket passes ensuring quick loading times that lead to high production rates of both the truck and excavator. The T 274 is also compatible with the brand new R 9600, the successor to the thoroughly proven and iconic R 996B.

RIGID DUMP TRUCKS – AUTONOMOUS HAULING

Command for hauling trucks now span class sizes from 190 to 360 tonnes.

Major autonomous hauling milestone for Caterpillar

In a major milestone in its autonomous hauling journey, Caterpillar has surpassed 3-billion tonnes hauled autonomously by Cat MineStar Command for hauling. The achievement coincides with an expansion of the types of commodities hauled autonomously across a growing number of Cat mining truck class sizes, as well as other brands of mining equipment. By Munesu Shoko .

W hen Caterpillar talks about autonomous mining, the company typically refers to it as a journey. It’s a journey for Caterpillar as the company develops innovative technologies and autonomy- ready machines. And it’s a journey for mining companies as they adopt and embrace new ways of mining. Michael Murphy, chief engineer in the Surface Mining and Technology organisation, has been on that journey with Caterpillar since the beginning. He has worked for Caterpillar for over 40 years and has been a part of the company’s mining technology group since

its inception over 20 years ago. The use of automation in mining has expanded dramatically in the past decade. But the building blocks to get there started being put together long ago. In fact, Caterpillar began its first autonomy programme over 30 years ago, starting with a research programme in 1985. By the 1990s, the company had two Cat 773 trucks running autonomously in a quarry operation. “Think of what your technology was like then – and what we didn’t have,” Murphy says. “A cell phone was about the size of a brick. We didn’t have the iPhone. We didn’t have an iWatch electronic watch. So thinking about

technology in those days, it’s amazing how we actually could get it to work. But we did.”

Major milestone Fast forward to 2021, Caterpillar is

reporting an additional 1-billion tonnes of material hauled by autonomous trucks using Cat MineStar Command for hauling, surpassing the 3-billion tonnes milestone. Complementing this major achievement is an expansion of the types of commodities hauled autonomously across a growing number of Cat mining truck class sizes, as well as other brands of mining equipment. “Since surpassing the 2-billion tonnes milestone, we have equipped more mines
