MWD6/0.3L Hydraulic excavator for coal mine

Functions and features:
■ This machine is suitable for rock loading, bottom cleaning and permafrost excavation operations in coal mines, metal mines, non-metallic mines, vertical shafts, inclined shafts and flat lanes. The machine has the following features:
■ Compared with traditional manual cleaning, using this machine greatly saves labor costs while improving working efficiency and improving the working environment. The operator works under the protection of the cab, which is conducive to safe production.
■ Compared with traditional diesel-powered small excavators, due to the use of electro-hydraulic system, this machine has the characteristics of energy saving, low noise, no exhaust pollution and high efficiency, and is more suitable for underground use.
■ The machine has a compact structure, small exterior size, and small assembly parts, making it easy to use vertically down the well.

■ This machine adopts a minimum rotary structure, and when the body is on the vehicle and rotates, its rear end will not exceed the vehicle width, so it is more suitable for small underground spaces.
