Driven by diesel engine; Suitable for scaling operations in tunnels and non coal mine hill and various underground projects.

The folding arm is fitted with the hydraulic hammer and translation mechanism driven by the rotating oil cylinder and it is capable of all-round operations of working surface, top plate, side wall and base plate.
Proportion pilot control is applied to the hydraulic system, characterized by flexible manipulation and smooth operations.
The equipment can considerably improve the scaling efficiency and safety based on compact structure, excellent mobility, small turning radius and powerful climbing capacity.
