HF-8A+ Percussion Drilling Rig
- Drilling Diameter: 300-2250mm
- Drilling Depth:300m
- Engine Power:75kW
- Traveling Speed:30km/h
Features
- 1All components are installed in the trailer, like electric motor, drive motor, hoist, mast etc. It is convenient for transportation.
- 2Use the crank link mechanism to change the power's gyration motion into alternating motion, through the steel wire rope to drive the hammer bit to do up-and down motion.
- 3Best choice for a large diameter drilling project.
- 4It is easy to operate, two workers will be enough.
Application
Mainly for foundation, construction piling, water well and borehole. It applies to various geological conditions.
