Kuhn Schweiz AG and Lithium Storage GmbH are the guys behind the massive, Hulk-green eDumper. They claimed their purpose-built electric truck would be the largest EV in the world when they first announced the project back in 2017. Well, it’s finally here – and the high-tech, 111 ton metal mammoth not only works as promised, but somehow looks even bigger than I remember!
That “works as promised” part up there is a huge deal by the way. This is because the eDumper isn’t just a big EV. It’s a big EV that actually powers the job site it’s operating at. It uses the truck’s massive batteries – two times larger than a Tesla sedan by the way – to power the empty truck up hill, then coasts back down with up to 60 tons of material in the bed. As it does so, the truck’s regenerative braking system generates incredible amounts of energy. More than enough energy in fact, to not only power the truck, but the site’s portable offices too!
It’s not a perpetual motion machine, obviously. Lots of energy goes into loading those 60 tons of material into the bed of the dump after all. Still, it’s worlds ahead of the diesel-powered alternatives, saving over 50,000 liters (13,200 gallons) of diesel fuel each year. Even better: using the company’s math, the eDumper actually reduces the amount of carbon produced by a job site it’s implemented at by 130 tons/year. That’s a huge, huge deal!
Check out the Komatsu-based eDumper in the pictures and company statement below, then let us know what you think of the big green electric truck in the comments section at the bottom of the page.
Komatsu HD605-7 eDumper Electric Truck
“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+ (electric) construction machines.”
