Introduction:
The crawler roadheader is a type of underground coal mine roadheader machine mainly used in rock roadway coal mining, semi-coal rock tunnel, railway tunnel engineering/projects, national defense caves, etc.

With a milling header, the crawler roadheader can worked in the coal roadway or semi-coal roadway with a hardness of f≤4. By exchanging the mechanical loader header and the milling header, the dual-purpose machine can work without a blasting driving.

Features:
1. The main hydraulic component is speed-changing gear box that is imported from Germany. The crawler road header is driven by hydraulic motor to make sure that the milling header work regularly under higher load. With inside atomizing and high pressure outside spray, the crawler road header has a good effect of putting out the coal dust.
2. The crawler roadheader has been designed with compact structure. The weight of the road header machine can ensure the stability in cutting rock which can enhance the working efficiency.
