PRODUCT FOCUS Elfsberg, Volvo CE’s director of emerging technologies. “We have been working with general purpose and production equipment in quarries for a long time, so we know them,” she says. “We can analyse and find efficiency improvement and we can easily compare before and after performance.” The technology could eventually be applied to large construction projects. Electric- powered construction equipment will also have the benefit of significantly reduced noise emissions — of particular concern in the urban environment. The electric machines offer new design potential to Volvo CE, which gives the performance of the entire worksite, according to Volvo CE director of design, Sidney Levy. “They create a great design opportunity by company an opportunity to improve the overall allowing us to remove conventional systems In October 2017, eMining AG announced that it had won the European eMove360° award with its eDumper – the world’s largest electric tyred vehicle. and components. This gives us the ability to explore different machine designs for better visibility and serviceability,” he says. development and testing of this prototype, applied sciences, the Swiss Federal Institute of on condition that the know-how acquired in Technology (ETH), and the EMPA were used to eDumper the course of this project benefit the Swiss design the individual components.

The truck will be used in the La of Energy and converted in Switzerland, will Measurements taken in the La Tscharner not use any diesel fuel or emit any CO 2 during workings, simulations at the universities of Tscharner extraction area from 2018 as a Plus Energy vehicle for cement production. its 20 or so daily trips. Instead, on the laden downhill run, the truck will generate electricity, which is stored in the battery. Some of this energy will be used to power the unladen truck back up to the extraction area, while the surplus will be fed into the grid overnight. ARGE eDumper, a partnership between Kuhn (Switzerland) AG and Lithium Storage GmbH, was commissioned by Ciments Vigier SA to build the first 100% electric replacement of a diesel-engined vehicle. Vigier was prepared to pay a substantial premium for such a vehicle, since the cost savings from the truck not using any diesel fuel over its planned 10-year life cycle and compensation will be substantial. The Swiss Federal Office of Energy also made a financial contribution to the non-amortisable additional costs for the 32 JANUARY 2018 from removing the need to pay any CO 2 The prototype eDumper will be used in a quarry operated by Ciments Vigier SA on the slopes of the Chasseral in Switzerland.
