MWD6/0.3L hydraulic excavator for coal mines
Function and features:
This machine is suitable for rock loading, bottom cleaning, and excavation of permafrost layers in coal mines, metal mines, non-metallic mines, vertical shafts, inclined shafts, and level tunnels. This machine has the following characteristics:
Compared with traditional manual bottom cleaning, using this machine greatly saves labor costs while improving work efficiency and working environment. The operator operates under the protection of the cab, which is beneficial for safety production;
Compared with traditional diesel powered small excavators, due to the use of an electric hydraulic system, it has the characteristics of energy conservation, low noise, no exhaust pollution, and high efficiency, making it more suitable for underground use;
The machine has a compact structure, small external dimensions, and small packaging components, making it easy to use vertically in wells;
By adopting a minimum rotation structure, the tail of the machine body will not exceed the width of the vehicle when it rotates on the vehicle, making it more suitable for working in narrow underground spaces.
