The machine adopts entirely hydraulicdrive by electric control. The configuration is compact, propulsion power is big and the extension of snatching is wide. It can load rocks in a complete cross-section and not remain dead angle. It doesn't need to clear the working face by man assistant. The main act of the machine is controlled by the pilot valve.
Operation is easy and work is calm and not impact. Capability is credible and maintain is facility. The machine has a good humanism design because it has hydraulic system with wind cool, seat, cab, electric adding oil and has alarm system for over-distance limitation, oil.
Temperature over height, oil route blocked, motor beyond load, and etc. These greatly alleviate the worker's labor intensity and increase the safety.
