pneumatic underground coal mining equipment

Adopt engineering plastic, light and flexible. High-power motor, more powerful. FRP cylinder, security and explosion-proof.

------APPLICATION

pneumatic drilling machine  is mainly used to bore holes for anchor rod and anchor rope supports in coal roadway, rock lane or other tunnel. Usually the hardness of rock is less than or equal f10. It  also can be used to install resin anchor rod and anchor rope, and meet the requirements of the early anchor preload force.

------FEATURES

    1,The roof bolter maximize adopting the engineering plastic and aluminum alloy material, lighter and easier operation. 

    2,The roof bolter adopts high-power motor, more powerful.

    3,The 3 stages air leg adopts glass fibre reinforced plastic cylinder, security and explosion-proof.

    4,Low noise and low maintenance.

    5,Compact structure, beautiful appearance, simple operation, easy maintenance.
