Coal Mine Repair Machine with Hydraulic Breaker, WPZ-37/600 (Machine for Tunnelling and Tunnel Repairs)
WPZ-37/600 coal mine repair machine is specially constructed for coal mine repair and maintenance, which is useful mining equipment for removing the road blockage in the mines. It can be equipped with a hydraulic breaker to crush rocks and coal blocks in an efficient manner. This machine is allowed to work on side wall, and floor in underground mine or tunnels.
The coal mine repair machine is featured by compact construction, small footprint, low noise, and high working efficiency, which can be used with scraper conveyor. This results in higher efficiency of repair and maintenace in mines. The tunelling machine features rotation angle of 360°, swing angle of ±35° left/right (amplitude ≥5000 mm) , and 350 mm lift (up/down), which assists in tunnel construction or tunnel renovation and expansion, etc.
