DPP-300 Truck Mounted Drilling Rigs For Water Well
Quick Detail:
1. There are more speed grade (8 grades), reasonable speed range,
with low speed but high torque.
2. The rig is adapted for core drilling with carbide and diamond
bit, It is also suitable for engineering geological exploration,
well drilling,blast hole, exploring gas and basic pile foundation
engineering.
3. It is convenient for you to treat trouble with two reverse
speeds.
4. By using hydraulic chuck, It is in strong and steady clamping
force. By using the hydraulic fed, the drilling rig can move back
directly.
