Start of work for the world's largest electric truck
The world's largest electric vehicle with an empty weight of 58 tons and a payload of 65 tons was baptised "Lynx" on April 20 in the presence of numerous representatives from business and politics and will start its work next week in the quarry of Vigier Ciment. The electric dump truck designed over the past 18 months is an example of successful applied research in Switzerland: the Bern University of Applied Sciences (BFH), the NTB Interstate University of Applied Sciences Buchs and the materials research institute Empa contributed to the planning and development on behalf of the eDumper working group. The project is supported by the Swiss Federal Office of Energy (SFOE).
The joint research work of the Swiss institutes has set three world records. The eDumper is the largest and most powerful battery-powered electric wheeled vehicle in the world. The vehicle already impresses visually: The driver reaches his workplace via nine steps; the tyres of the E-Mobile have a diameter of almost two metres. The environmentally friendly eDumper has been completely rebuilt from a dieselpowered Komatsu HD 605-7 dump truck and now houses the largest battery ever produced for an electric vehicle instead of a diesel tank. At 4.5 tons, the battery with Li-ion cells is as heavy as two com-plete passenger cars. Never before has a comparable vehicle been able to save such a large amount of CO2.
Brakes are for winners!
The eDumper will transport lime and marl rocks from a higher mining area to a lower processing plant. During the fully loaded descent, the batteries are charged by recuperation of braking energy. According to preliminary calculations, the electricity generated in this way is largely sufficient for the unloaded return journey uphill to the mining area. Thus, the vehicle would be be a zero-energy vehicle. The exact energy balance of the eDumper will be shown by investigations in everyday operation over the next few months. Not only the conception of the eDumper was done in Switzerland, also the finally installed components are partly from Swiss mediumsized companies: the actual conversion took place at Kuhn Schweiz AG in Lommis (TG) and Heimberg (BE).
