Electrical Mining Excavator
electrical mining excavator
This machine is suitable for rock loading, clearing and excavation of frozen soil in coal mines, metal mines, non-metallic mines, shafts, inclined shafts and roadway excavation. The machine has the following characteristics: Compared with the traditional artificial clearing, the machine can greatly improve the working efficiency while saving the labor cost, improve the working environment, and the operator is working under the protection of the cab, which is beneficial for safe production. Compared with the traditional diesel-powered mini excavator, the electric hydraulic system has the characteristics of energy saving, low noise, no exhaust pollution and high efficiency, and it is more suitable for underground use. The machine is compact in structure, small in size and small dispensing parts, which is convenient for vertical downhole use. With the smallest swing structure, when the body turned on the car, the tail will not exceed the width of the car, so it is more suitable for working in small space underground.
