Mining electric excavators use an electric motor and hydraulic system instead of a diesel engine. The underground MWD series holds coal safety certification, features explosion-proof design, zero exhaust and low noise. Its compact body and short-tail slewing make it ideal for mucking, dinting and roadway profiling in narrow roadways. It delivers high starting torque, simple maintenance and low power consumption cost. Fitted with a quick coupler, it can be equipped with hydraulic breakers to integrate excavation, loading and breaking in one machine.
