UG LOAD AND HAUL believe in the highest possible level of training of both GHH and client personnel. The availability and economic efficiency of the operation is dependent on the qualification of operation and maintenance personnel. For this reason we offer proven training concepts with our GHH training academy at our headquarters or on-site.” Additionally, GHH offers long term service contracts. These, for instance, include inspection or maintenance as well as overhaul. Additional service options can be agreed with clients on an individual basis. “We support customers with special service facilities, so that a 24/7 service and an immediate spare parts supply can be guaranteed.” On automation, GHH says it carefully analysed the mining market “and found that automation systems need to be both lean and robust in order to work efficiently in a complex, rough and often dynamic mine environment. Many of the systems were not designed for that and users find that already remote operation in combination with functional automation results in similar safety levels and productivity with much less cost and greater flexibility.” Therefore the company has opted for a twotier approach with two different research projects based on long-term experience in this field. In a project titled Accessible automation for a more efficient and safer underground mining in Chile funded by Germany’s GIZ, GHH has developed a simplified automation system with partner AMTC at Universidad de Chile. “On the other hand we are part of a larger project network called UPNS4D+, which will utilise robust radar scanners from indurad and new navigation algorithms. The first tests will commence this year and the goal is full automation of the LHD cycle. While the first project focuses on simplicity and ease of use the second focuses on robustness and highest degree of automation without time-consuming teach-ins. Furthermore, we understand that systems need to be as open and non-proprietary as possible with common interfaces in order to be widely applicable.” On electric operation, Riedel states; “GHH Fahrzeuge is not stuck to the proven electric technologies with supply from a cable. However, we have long experience in this field and could make a real difference by combining the electric motor with our hydrostatic drive. In terms of electric drives there is a lot of movement and we are looking at this closely but it will take some time for the battery tech
