The CYTM41/2(D) mining hydraulic roof bolter is mainly suitable for roof bolting operations in various narrow roadways and tunnels in metal mines and other underground engineering projects. It can perform roof bolting operations in roadways of 2.8m×2.8m. The bolter adopts an electronically controlled hydraulic drilling system, which is advanced and equipped with an anti-jamming device, featuring fast drilling speed and high working efficiency. The whole vehicle has a compact structure, is highly maneuverable and mobile, and can greatly improve the working environment, construction efficiency and construction quality.
