Main Features ------drilling machines in tunnel

1. It is separate in structure, small in size, light in weight, flexible in movement and convenient in operation.

2. The hydraulic pump is driven by explosion-proof electric motor through operating system, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the same time, the movement of drill head is realized by oil cylinder & chain double speed mechanism.

3. Hydraulic chuck can satisfy the function of shackles and power-off protection.

4. The sliding and extending & retracting function of the mast makes it convenient for the bottom of mast to touches the ground or platform, thus the drill rig will be more stable.
