Main features of drilling machine power head: 1. Simple structure, convenient operation, low cost;

2. removable low center of gravity well, moving transportation convenience, particularly suitable for rough rugged terrain or the original topography;

3. the impactor with low air consumption, and air compressor exhaust volume required to support small, energy-efficient economy;

4. Rotary reducer torque, strong vibration, high loading work condition and reliability.

5. electrical system overload protection and phase failure protection, drilling rig operation is stable and reliable.

6. propulsion system is configured with a pressure reducing valve, can be adjusted according to the different rock conditions propulsion, for best rock effect.
