Product Description:

Technical characteristics
1. Split layout, small size, lightweight, easy to move, and flexible operation.
2. The power unit uses an explosion-proof motor and control system to drive the hydraulic pump, and the motor drives the main shaft to rotate and the cylinder chain double-speed mechanism to realize the feed and rotation of the powerhead.
3. The hydraulic chuck fully meets the drill pipe clamping, shackle, and power-off protection functions.
4. The mast sliding and telescopic function makes it convenient for the mast to be close to the foundation when drilling to enhance the stability of the work.
5. The up and downswing of the swingarm and the mast are suitable for the needs of opening holes at multiple angles.
6. The powerhead spindle speed range is wide, and the rotating torque is large.
