Zero emissions with the eDumper, the perfect match for sustainability
Duratray’s Suspended Dump Body has been the perfect match for the first environmentally friendly lithium-ion-powered truck operating in Switzerland since January 2018.
This unprecedented equipment was the successful result of ongoing collaboration between Duratray and international energy specialist Kuhn Group, which combines Duratray’s low-noise, low-carryback Suspended Dump Body (SDB) with Kuhn’s expertise to produce an eco-friendly dump truck.
This unique concept, backed by the Swiss Federal Office of Energy, is that the Komatsu HD605 does not use fuel or emit any CO2 during its trips. Instead, the truck generates electricity on the laden downhill run, which is stored in its large battery. Some of this energy is used to power it unladen back up to the extraction area, with the surplus fed into the grid overnight.
Net Electricity Exporter
During each of the 20 downhill runs, the batteries are charged by 40 KWhr, making the vehicle a net electricity exporter. This surplus is estimated at up to 200 KWhr per day.
Duratray’s Contribution to Environmental Efficiency
Duratray’s SDB provides an excellent complement to the eDumper’s goal to make mining environmentally friendly as it reduces noise and reduces carryback, which in turn decreases waste and repeat trips, improving overall efficiency.
