Greentech in Switzerland
Switzerland has been a manufacturing location for high-tech and special-purpose vehicles for over 100 years.
Swiss industry develops locomotives, aerial cableways, trolley buses, construction machines, agricultural and military vehicles, as well as electric vehicles and aircraft. The research, development and marketing of heavy electrical transport and construction machines should be added to this tradition. A fully laden Komatsu e-Dumper from Kuhn Schweiz AG (total weight 111 tonnes) transports 60 tonnes of lime and marl from the high-elevation extraction area to the
permanently installed transport system. Energy recovered on the downhill (laden) run is stored in batteries, provided by Lithium Storage GmbH, and is used to power the uphill (unladen) run, and the surplus is fed into the electricity grid. With a history of constructing electric goods vehicles, Kuhn Schweiz AG is defining a new goal: the development, construction and marketing of electrified 100-tonne+ construction machines.

The interaction of propulsion, storage and energy recovery
The technical mapping of the enormous torques represents a major challenge.
Electric motors deliver torques of thousands of newton metres (Nm) and a far higher range of speeds. In terms of the energy requirement, the numerous accessory systems (e.g. hydraulic pumps) must also be considered. Extremely high charging currents are produced by the kinetic energy recovery system which operates to give braking effect on the downhill section.
