VDMA 14 VDMA MINING SUPPLEMENT • 2017 By any standard, the machines employed by modern open-pit mines to extract, load and haul rock are some of the largest pieces of equipment on Earth. Moreover, these machines are expected to per- form at the same optimum level as any other operation. Reliability is extra important. Having a bucketwheel, a dragline, a shovel or a couple of haul trucks down for even a shift can be an incredibly costly proposition. These large pieces of equipment also rely on a host of support equipment. With conventional mining processes, dozers clear the bench for the shovels, while front-end loaders keep the loading area clean, reducing tire damage on the trucks. Sometimes those same loaders can be the primary loading tool. Engineers today are looking beyond conventional load-and-haul strategies to more continuous material handling methods, such as in-pit crushing and conveying (IPCC). These systems could also be used in connection with continuous mining systems, such as sur- face miners and bucketwheel excavators. The theme of this edition of the Best of Germany is "Commit- ment to the Mining Space," and Liebherr Mining identifies strongly with that. The company is privately held with a long-term vision and they support the mining industry during good times and the not so good times, albeit with a bit more diversification than others. For the open-pit mining sector, Liebherr supplies equipment for loading, hauling and pushing rock. This type of equipment requires an extended lead time to manufacture. Similar to a mining opera- tion, an equipment manufacturer cannot simply turn the truck or excavator factory on and off at the flip of a switch. For the last few years, Liebherr managed to keep most of their people in place and they also invested in their manufacturing facilities and a few new service and support facilities in mining districts. When miners return to the market for new equipment, they will be prepared. In the meantime, the company has also been working to improve its service and customer support strategies. Liebherr continues to integrate vertically. A prime example is the expanded use of the Li- ebherr electronic (or Litronic) system, which integrates the AC drives with the drivetrain in the case of the haul truck. Last year, they also unveiled the new V-diesel engine D9812, which has a power rating up to 2,700 hp (2,015 kW). "The real message here is that we con- tinue to invest in the development of our own components," said Dr. Joerg Lukowski, executive vice president, mining equipment, for Li- ebherr. "Next door to the excavator factory in Colmar, we have built a high-horsepower engine factory. Since we have started to introduce the Liebherr engines in our 100-ton diggers, we have more and more customers already asking for Liebherr engines in the larger diggers and in the trucks. People are excited about them, but we need to prove the engines are reliable and fuel efficient." Liebherr invested in a new service center in Adelaide, an iron ore support center in Newman, a parts facility in Perth, a new ser- vice center in Siberia and a new facility for the oils sands in Fort Mackay, Alberta. "We have target markets and we continuously invest in those regions," Lukowski said. "Liebherr Australia for example is already well-established throughout the continent, but still we continue to invest. We needed a remanufacturing facili- ty in Adelaide and we decided to build one. In the Americas, we do not have as great a presence as we would like and so we put focus here to expand our project base. If we have an individual project somewhere that needs support, we will make an on-site investment with a repair facility and spare parts. If more projects appear nearby, we may decide to invest in a full-service facility. In markets where we have critical mass, we usually then finally build a Liebherr-owned company." Surface Mining: Increasing Reliability and Productivity Ultimately, the lowest cost per ton prevails Liebherr's T 284 haul truck has a 400-ton payload, the highest in the industry. Ground engaging tools (GET) has been a very successful aftermarket item for Liebherr.
