In a Swiss career a 110-ton electric dump truck is in operation, which never needs to be recharged as it stores enough energy during a descent with a load.
The world’s largest electric vehicle is used to transport lime and frozen soil from the side of the mountain to a cement plant near Biele. However, it stands out not because of its size, but because of its unique power technology that allows it to operate continuously without consuming energy from external sources..
The bottom line is that a 45-ton eDumper dump truck drives into a 13-degree rise and picks up 65 tons of ore. Then on downhill slopes with more than double the weight, the giant’s regenerative braking system collects enough energy to fully recharge the battery., necessary for lifting.
Every day the dump truck makes about 20 trips and in a year produces about 77 MWh of electricity, which allows you to save from 50 000 to 100 000 liters of fuel, compared to a typical diesel equivalent.
eDumper is developed on the basis of the Komatsu HB 605-7 platform with two-meter wheels and body dimensions of 9.1×4.34×4.34 m.
The electric dump truck is equipped with a 600 kW battery weighing 1982 kg, 982 kW engine and can accelerate to 40 km / h.
We also previously reported on development of an automated follow-up system that allows one person to efficiently drive two trucks at the same time.
