VDMA 51 2017 • VDMA MINING SUPPLEMENT Liebherr introduced the R 9200 hydraulic excavator to the North American mining market at MINExpo 2016. Equipped with an ad- vanced package of ground engaging tools (GET), the 9200 has a 16.3-yd 3 (12.5-m 3 ) bucket capacity, which offers the biggest payload in its class. This new 200-ton machine is designed to match mining trucks with payloads of up to 140 tons. "The GET has been a very successful aftermarket item for us and it has been received well by many customers," Lukowski said. Liebherr has also added high-performance kits for its hydraulic excavators. Lukowski explained: "We have also used a targeted ap- proach to reduce the weight of the attachment while maintaining the lifetime of the components. We have seen as much as a 13% gain on the large mining excavators." The Litronic systems for the haul trucks has been developed through a similar evolutionary process that started with the 282 and then became available with the 284 and the 236. "It's different sys- tems working together, it's not just one element or one part in a haul truck," Lukowski said. "It's a combination of several components that increase productivity and efficiency. We have demonstrated it on the 284 where the Litronic Plus AC drive system also includes the drive- train." The T 284 haul truck offers the highest payload in the industry (400 tons) and with intelligently designed systems and components, it could serve as a platform for future advances in mining truck tech- nology. Buyers can select the engine that will allow the truck to meet productivity targets while minimizing fuel consumption. Liebherr-Mining Equipment has developed an advanced software tool to improve troubleshooting efficiency, the Troubleshoot Advisor. It detects the cause of breakdowns for mining trucks and excavators and proposes a procedure based on the results of diagnostic tests. "This software tool is currently supporting field service teams in more than 20 countries, and they have been able to reduce fault finding and trouble-shooting by a factor of five," Lukowski said. Lukowski expects the cost per ton to remain a hot topic. "Some purchasing managers tend to focus on initial capital costs rather than the cost per ton," Lukowski said. "At the end of the day, what counts is the lifetime equipment costs per ton. And that is where uptime and high productivity of our machines also plays a major role." Looking toward the future, he sees smaller machines doing the same work as larger machines, where a 400-ton machine is producing as much as a 600-ton machine today. Digital Asset Care Since it was established in 2015, RWE Technology Interna- tional (RWE TI) has developed into a leading independent consult- ing and engineering company, providing services to various energy markets including mining, thermal generation, renewables and grids. The company provides services to the global mining industry with a special emphasis on continuous open-cast mining and in-pit crushing and conveying (IPCC) Technology. "Our mining expertise covers minerals and solid fuels and spans exploration, development, operations and rehabilitation," said Over a period of 6 days and five nights, a team of 24 technicians, electricians and supervisors worked around the clock to complete the R 996 B engine module changeover at Yancoal's Moorlarben site.
