Tunnel Repair Machine Introduction
The WPZ-7.5/200L coal mine tunnel (bottom drum) repair machine is a professional tunnel repair equipment developed for the deformation of surrounding rocks in old tunnels in coal mines.
It is fully hydraulically controlled, has its own crawler track, and has two operating modes: remote control and manual, has the functions of mobile crushing and excavation in coal mines, mainly used for the bottoming, expansion, loading and unloading of underground coal mine tunnels (especially small and medium tunnels). This equipment has the characteristics of compact structure, easy operation, large crushing force and high working efficiency, especially suitable for narrow working spaces underground.
