DescriptionParameter

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.


5. The swinging arm and mast can do luffing movement, which satisfy the request of 
multi-angle
 drilling.


6. The range of spindle rotating speed is wide and the torque is large.
