VDMA 45 2019 • VDMA MINING SUPPLEMENT Mining TAKRAK recently refurbishes this 33-year-old BWE in Kazakhstan. we load all the know-how in the TroubleShoot Advisor, which we make available for the Liebherr service force and also for custom- ers so they can make use of mobile terminals for fault finding." Customers have told Liebherr that the tool has reduced fault-finding procedures by a factor of five. "Those devices will eventually be replaced with units on the machine, but we don't want the operator to be overwhelmed with data," Lukowski said. "The service people should also have onboard functionality. With their key card, they can access more data than the operator." When it comes to data, Lukowski said he routinely encoun- ters two types of customers — the ones that say they are inter- ested in all the data and another group that only wants actionable data. "Our customers should not have to invest their time in de- ciphering the data," Lukowski said. "Using intelligent algorithms, we can provide the data to them in a more organized format. They can have all the data if they want it. We are very open in the re- gard, but we believe there is more value in actionable data. Know- ing the oil temperature was within limits for the last four weeks wouldn't be useful. Knowing when the oil temperature increases to over and above the limits, however, would be important." Liebherr continues to build the large T 284 and T 264 haul trucks in Newport News, Virginia, USA. "An important haul truck project for us is trolley assist," Lukowski said. "We have die- sel-electric trucks and they can be equipped with trolley assist. We have T 284s operating with trolley assist in Zambia and Pana- ma. We also have some trolley assist interest with the T 236 haul truck too." Looking toward the future, Lukowski marvels at the acceler- ating pace of technology-related improvements, especially with the electric drives and the sensors used in digital systems. "If we can improve the performance of excavator and lower the operating costs for users, they can consider higher stripping ratios," Lukowski said. "Drones are being used extensively in agriculture to improve safety and productivity and those technologies will likely influence the mining business. The drones could be used to better assist the truck loading process." Meanwhile, Liebherr continues to strengthen its footprint in the mining business. The company's facility in the Kuzbass has been completed and the company has made a significant invest- ment in its facilities in Western Australia. Last year, they built a small support shop in Panama for haul trucks. Liebherr has more project-related investments planned for 2019. Tailored Training Courses RWE Technology International (RWE TI) tailors OpEx-training pro- grams to meet specific customer needs, covering technical, eco- nomical and/or administrative aspects of mining and power plant operations. "The tailored training solutions are designed to grow our customers organization through skilling its people and future staff," said Dr. Martin Schmid, senior mining engineer and training expert for RWE TI. "Many of these classes are facilitated in collaboration with engineers and operating staff from the RWE Group. Through sharing hands-on operational knowledge, we offer genuine value to our customers." The programs that RWE offers are mainly intended for engi- neers, specialists, experts and middle managers, having several years of working experience. Trainees profit from the vast exper- tise and knowledge available within the RWE network, and gain valuable insights in mine operation, power plant management, operation, maintenance, health, safety and environment. Programs may include best-practice exchange with RWE peers, lectures, workshops, seminars, discussions in small groups, study visits, shadowing, case studies and mentoring. "We also take pride in ensuring participants understand how to use their new skills in practice to increase efficiency and optimize operations and production back home," Schmid said. "Therefore, training courses may range from days up to months, with flexible locations, depending on the content choice and in- dividual training needs. Trainings may take place in Germany at RWE offices and sites, or at the mine site, depending on what is most cost-effective. We offer experienced mine experts to join participants in their daily work in-house at their company or on- site their plant site." In the case of RWE on-site trainings, the company assists its cus- tomers with necessary conditions such as accommodations, travel, and an interpreter to enable a comfortable and efficient learning environment. As far as the training course content, customers can always rely on their experts to advise on which training scheme to adopt to meet training preferences and requirements. During a typical training day, a small group (three to four peo- ple) with similar learning objectives is guided by one of RWE TI's facilitators to meet and exchange best practice with RWE opera- tional experts during a workday. The day starts with a theoretical classroom session followed by practical site visits in the afternoon, according to carefully prepared learning schedules. To internalize the course content, RWE provides the online learning platform MOODLE for participants to summarize their lessons learned at the end of a training day. Participants are awarded with certificates, recognizing attendance and course subjects.
