Dana shifts Spicer gears for underground LHDs, mining trucks and wheel loaders

Dana has announced the development of the Spicer® TE50 powershift transmission designed for large LHDs, underground mining trucks and wheel loaders.

Engineered for vehicles from 400-600 kW (544-816 hp), the Spicer TE50 transmission offers superior performance through improved fuel efficiency, smoother shifting, more precise vehicle handling, and optimised braking, according to the company. The transmission will launch with vehicle manufacturers in the second half of 2019.

Aziz Aghili, President of Dana Off-Highway Drive and Motion Technologies, said: “As the market for mining and construction vehicles moves toward larger vehicles, demand is growing for advanced technologies that support greater productivity without sacrificing precise handling. The Spicer TE50 transmission delivers a robust solution that meets the performance requirements of heavy-duty, high-power applications that operate under some of the most challenging conditions in the world.”

The Spicer TE50 transmission is engineered to fit within current vehicle design envelopes and is offered with a four- or eight-speed gearbox for optimised shifting ratios. It is available with advanced automatic lockup, which improves fuel efficiency by enabling direct drive even at low speeds, Dana said.

An integrated, automatic retarder reduces brake wear and enables smoother, quieter braking. The new transmission is also equipped with three heavy-duty, auxiliary pump drives.

Visitors to the Bauma fair on April 8-14, will be able to see the new Spicer TE50 transmission and Dana’s other innovations for the mining and construction industries in hall A3, stand 325, as well as an outdoor vehicle demonstration area between halls A4 and A5.

Liebherr to showcase wheel loader safety additions at Bauma

At Bauma 2019, Liebherr will for the first time present a package of multiple intelligent assistance systems for its XPower® large wheel loaders.

These systems include new active rear person recognition and a sensor-supported, integrated tyre pressure monitoring system. All systems have been developed by Liebherr and are fully integrated into the machine control.

Another Liebherr wheel loader world premiere is a new intuitive steering system that will be available for all mid-and large-series models from Bauma 2019 onwards.

From the smallest wheel loader, the L 506 Compact, to the largest model, the L 586 XPower, Liebherr will be displaying a cross section of all wheel loader size classes at the bauma show on April 8-14 in Munich, Germany.

The small wheel loaders, up to the L 509 Stereo, and all large wheel loaders of the XPower generation will be available with Stage V emission standards compliance for the first time from April this year.

Rear person recognition

The company said: “Liebherr’s new assistance systems increase comfort and safety in daily operation in a range of ways. One of their advantages is that they enable machine operators to concentrate more on operating their Liebherr wheel loader by removing additional distractions. For example, the active rear person recognition automatically provides a warning on the machine display and sounds acoustic signals if there is danger in the wheel loader’s rear area. A special feature of this system is that it uses sensors to automatically differentiate between people and objects with the aid of sensors.”

If a person moves in the area behind the machine, the system alerts the machine operator. The active rear person recognition is activated at a greater distance than warning systems for inanimate objects such as walls or columns. The operator therefore receives a more precise warning if there is a risk of personal injury. The active rear person recognition avoids an overload of warning signals, which in turn reduces the burden on the machine operator, while reducing or eliminating serious accidents.

Tyre pressure monitoring system

“Tyres are among the most expensive wearing parts on a wheel loader. Incorrect tyre pressure leads to increased wear and rising fuel consumption and results in high costs. Other negative consequences are stability limitations and reduced manoeuvrability. It is therefore important to address potential tyre pressure problems in good time,” the company said.

Liebherr offers a new integrated tyre pressure monitoring system for this purpose, which detects tyre pressure deficiencies early, ensures good manoeuvrability and increases the lifetime of the tyres, according to the company.

With the aid of sensors, installed on the tyres and protected from damage, the system records the status of the tyres and indicates this on the machine display. If there are deviations from optimal tyre pressure, the machine operator receives a warning notification on the display. This allows the operator to act early if there is insufficient pressure or excessive temperature levels in order to avoid safety risks and high associated costs.

The integrated tyre pressure monitoring system is available as standard for many wheeled earthmovers and container handling machines across the Liebherr group of companies.

LiuGong achieves wheel loader milestone as it celebrates 60th anniversary

LiuGong celebrated its 60th Anniversary at a ceremony in LiuGong International Industrial Park in Liuzhou, Guangxi, China, today, at the same time as heralding the production of its 400,000th wheel loader.

Attendees at the event included domestic and overseas customers, distributors, suppliers, government officials, shareholders, and stakeholders who have worked with LiuGong throughout its 60 years.

LiuGong, in addition, said the milestone wheel loader achievement was made through the “unremitting efforts and proactive technological innovation of all LiuGong people in the past six decades”.

“This is a milestone worthy of celebration in the history of LiuGong,” it said.

At the same time as all of these celebrations, the company debuted at the ceremony six new products including a 990F excavator, B170DL bulldozer, S935 sugarcane harvester, TC800C5 crane, 4180D motor grader and 886H loader.

Six decades of history

Established in 1958, LiuGong not only pioneered the production of loaders, it also laid a solid foundation for the technology, talent cultivation and management for the development of the construction equipment (CE) industry in China, the company said.

In 1958, Shanghai Huadong Steel Factory allocated some employees and pieces of equipment to Liuzhou, Guangxi, to facilitate the economic development in southwest China. In a wilderness on the west bank of Liujiang River, they built a factory from nothing.

In 1966, LiuGong rolled out the first wheel loader accredited by China, which opened a new chapter in the company’s development. In 1993, LiuGong began trading on the Shenzhen Stock Exchange and became the first listed company of the CE industry and Guangxi. Since 2000, LiuGong has been looking beyond its loader business and working on cross-regional operations and expansion of its product lines. So far, LiuGong has 32 complete product lines in six categories to meet customer demands of various applications as well as extreme operations.

In April 2002, LiuGong successfully produced 899 loaders in one month, which was known as ‘899 Campaign’, a huge leap of production at that time.

“Taking this opportunity, the company launched its reform towards becoming a modern company. Afterwards, its Board of Directors promoted to build an ‘open and globalised’ LiuGong, boarding the fast lane for the company’s globalisation, which was shown in its fast growth of overseas revenues,” the company said.

“Backed by its historical legacies, LiuGong has developed the core values of “customer oriented, assuring the future by quality; people foremost, create value through cooperation”, striving to build an international brand that leads China’s machinery industry.”

Along with China’s entry into the World Trade Organisation, LiuGong started to build its eastern bases and added multiple product lines into its portfolio. In 2003, LiuGong developed its first overseas distributor in Morocco, north Africa, and started its globalisation. LiuGong has been building its global presence of 10 overseas subsidiaries, nine overseas regional parts distribution centres and more than 300 distributors in over 100 countries. All LiuGong products and customers are supported by five R&D centres worldwide.

In 2012, by the acquisition of civil construction machinery segment of HSW in Poland, the company laid a solid foundation for export of China’s proprietary technology and products to the European Union. Today, LiuGong produces its products in China, India, Poland, and Brazil.

Also, LiuGong India Company and LiuGong Dressta Machinery have been awarded the ‘Best Foreign Investor’, ‘Model Enterprise for China-India Cooperation’, and the ‘Best Employer’ by local governments.

As the “Belt and Road” initiative continues to advance, LiuGong has expanded its footprint to 85% of the countries among the 65 key countries along the route. Its products participated in many major projects along the belt such as the Pakistan PKM Motorway, China-Laos Railway, and Jakarta-Bandung Railway.

In 2008, LiuGong set up SinoEver Financial Leasing Company in Beijing, becoming the “pioneer company in manufacturer leasing” and LiuGong entered the crane business by acquiring Zhengchonganli Engineering Machinery Company in Bengbu.

In 2010, LiuGong acquired Liuzhou OVM, a world leader of pre-stressing products and technology, and started the construction of an eastern manufacturing base for excavators in Changzhou. In 2011, LiuGong bought into the piling foundation industry by holding shares of Jintai, China’s leading brand in piling machinery, and opened a JV with Cummins in Liuzhou.

In 2012, LiuGong opened its hydraulic company and, in 2013, LiuGong and Metso started a joint venture to produce mobile mining crushers and grinding mills, while the company took over an air compressor business in Liuzhou.

In 2016, LiuGong entered the modern agricultural equipment sector when the Luzhai plant, with world-class technologies, was put into operation. And, in 2018, LiuGong started forward with producing intelligent manufacturing systems, mining machinery, forestry machinery, and aerial work platforms.

R&D

“LiuGong has never stopped investing in R&D even during the most difficult years. In 2015, LiuGong launched National Earthmoving Machinery Engineering Research Centre and LiuGong Global R&D Centre, making LiuGong the only national demonstration base for technological innovation and industrialisation of earthmoving machines.

“A total of 19 product lines at LiuGong have been upgraded and 18 new products have hit the market, including a range of machinery for sugarcane planting, heavy-duty mining excavators and loaders, mining trucks, large dual-wheel cutters, smart manufacturing system, and mobile compressors.

“LiuGong has evolved to be a global provider of total solutions. In 2016, LiuGong presented the world’s first vertical lift wheel loader. And, the new generation products of H-series loaders, E-series excavators, D-series rollers and motor graders, and C-series forklifts now are available all over the world and have been contributing more and more in sales revenue.

“A custom designed torque convertor was independently developed and manufactured for LiuGong’s 8128H with many innovative technologies and approaches; and the hydraulic grab by Shanghai Jintai is among the best of its kind globally.”

In the past five years, LiuGong, OVM and Jintai had numerous achievements in R&D, including three National First and Second Prizes for Progress in Science and Technology, and 14 ministerial and provincial-level science and technology awards. LiuGong also participated in drafting of industry standards, both for international and domestic markets, making its own voice heard in the industry.

“Today, with more than 1,000 engineers and a continuous investment in R&D, LiuGong comes up with an outpouring of products with cutting-edge technologies,” the company said.

“Over the past six decades, LiuGong has kept a close bond with its customers, distributors, suppliers, shareholders, and other stakeholders to weather through difficulties and share success together.

“During industry downturns, LiuGong took a series of quick actions like capacity adjustment, organisational reform, team optimisation, cost control, sustained input into technological innovation and product development internally and optimise the marketing channels externally. As a result, distributers, direct subsidiaries and joint ventures have become new drivers of our rapid growth in China.

“As the economy warms up, the excavator business becomes our growth pillar with the highest revenue and profit and LiuGong has significantly improved market competitiveness on a global level.”

Aiming for 100

LiuGong says it is committed to providing extraordinary construction machinery products and services to customers around the world.

“Our endeavour of developing first-class advanced technologies is a valuable asset to LiuGong’s ambition to be a century-old enterprise in the world.

“Sixty years is but a brief moment for LiuGong, who is setting sail on its next journey. Amid the national reforms and industry transformation, LiuGong will adhere to a ‘Total Globalisation, Total Solution, and Total Intelligence’ approach with greater intelligence, courage, and passion.

“Standing at not only a historic stage but as at a turning point for the company, LiuGong will insist on SOE (state-owned enterprises) reform and development; insist on focusing on customer service; insist on innovation and independent R&D; insist on building a dynamic and motivated team to continue to write a new chapter for the company.

“And, in the future, we will continuously provide products and services tailored for local market; we will outdo ourselves in branding, manufacturing, R&D and marketing and strive for continuous progress; we will take on the mission of revitalising the CE industry in China.”

The company concluded: “The one who digs deep will someday leap high and become a legend. Guided by our mission and vision, LiuGong will usher in a new era with much greater confidence and look forward to a centurial business.”

Volvo CE goes all-electric at Skanska Vikan Cross quarry

Volvo Construction Equipment has started a 10-week trial of its ‘Electric Site’ concept at Skanska’s Vikan Kross operation, near Gothenburg, Sweden, as the two companies look to create the world’s first emission-free quarry.

The project, which incorporates electric and autonomous Volvo machines, will run in a real production environment aiming to achieve the same output as Skanska’s usual equipment, and is expected to deliver an anticipated 95% reduction in carbon emissions and 25% reduction in total cost of operations during the 10 weeks.

Drawing on the electromobility and automation expertise of the Volvo Group, the research project, dubbed Electric Site, aims to electrify each transport stage in a quarry – from excavation to primary crushing, and transport to secondary crushing – with only a negligible amount of diesel power being used.

Gunnar Hagman, CEO of Skanska Sweden, said: “This is the first time that anything like this has been attempted in the quarrying industry and, if successful, Electric Site could serve as a blueprint for transforming the efficiency, safety and environmental impact of quarries around the world.”

Its success will no doubt have ramifications for the mining industry, too.

Melker Jernberg, president of Volvo CE, said: “We have had to completely rethink the way we work and how we look upon machine efficiency – pushing the boundaries of our competence. The total site solution we developed together with our customer Skanska is not a commercial solution for sale today, and we will evaluate the outcome of the tests, but we have learnt so much already, elements of which will be fed into our future product development.”

The project has involved developing new concept machines, work methods and site management systems which, together, form a complete site solution. New technology encompasses machine and fleet control systems and logistic solutions for electric machines in quarries.

Three rigid haulers, for example, have been replaced by eight smaller prototype HX2 autonomous, battery-electric load carriers to transport the material from the primary mobile crusher up to the secondary static crusher.

This protoype has advanced significantly since the HX1 was first shown to customers and members of the international press at the Volvo Exploration Forum in September 2016, according to Uwe Müller, chief project manager for Electric Site at Volvo CE.

“The HX1 was our proof of concept,” he said. “Once we knew it was feasible, we updated the design requirements for the HX2 to incorporate shared technologies and components from the Volvo Group, such as electric motors, batteries and power electronics. Integrating a completely new drivetrain was crucial to take full advantage of the groundbreaking electromobility developments that are happening inside the Volvo Group.”

Another new feature is the addition of a vision system, which allows the machine to detect humans and obstacles in its vicinity, he added.

The primary crusher on the Skanska site is loaded by the 70 t dual-powered, cable-connected EX1 excavator prototype, which had not previously been seen by customers and press. The base machine for the EX1 is a Volvo EC750 model upgraded to incorporate an electric motor in addition to diesel engine.

“To fit the new components in the machine without increasing its size required a significant amount of repackaging work,” Müller said. “However, in terms of the operator interface and controls, nothing has changed – it’s operated in exactly the same way as a conventional Volvo excavator. If the cable is connected, the machine will automatically start in electric mode. If it’s not, it will start in diesel mode.”

Because the machine will be relatively static – only moving a few meters once or twice a day as the excavator works its way through the blasted rock – it is ideally suited as a fully electric machine on a cable, he added.

The stockpiles of material on site are organised by the LX1, Volvo CE’s prototype electric hybrid wheel loader. The machine can deliver up to a 50% improvement in fuel efficiency, as well as significant reductions in emissions and noise pollution compared to conventional counterparts.

The LX1 is a ‘series hybrid’ incorporating a driveline that consists of electric drive motors mounted at the wheels, electric-driven hydraulics, an energy storage system, a significantly smaller diesel engine and new machine architecture, including a new design of the lifting unit.

“It is this combination that enables the substantial gain in fuel efficiency,” Volvo CE says.

The prototype – which has 98% new parts and a fundamentally new machine design – can do the work of a wheel loader that is one size larger, according to the company.

Volvo CE teamed up with its customer Skanska Sweden, the Swedish Energy Agency and two Swedish universities – Linköping University and Mälardalen University – in October 2015 to collaborate on the SEK203 million ($22 million) Electric Site project.

Volvo CE is coordinating the project and is in charge of developing the machines and systems. Skanska Sweden is providing logistical solutions, application relevance and job site knowledge. The Swedish Energy Agency is helping to fund the project and the universities are carrying out research. Two PhD students are looking at battery ageing and energy management for electric vehicles, as well as functional safety.
