eMining AG offers electrically powered specialty vehicles. In these retrofits, the diesel engine and fuel tank are replaced with electric drives and high-voltage batteries. OSWALD developed a special motor for the 110-ton eDumper shown here (fully loaded). The eDumper transports up to 45 tons of limestone and marl from the mountain to the valley. On the way down, the batteries are recharged through regenerative braking. With a full battery and an empty load, it then travels back uphill using only electric power. During operation, the eDumper never needs to be charged from the grid.
