Features:

1. High efficiency. As the rig uses a hydraulic chuck with large inner hole, a fixed 6m drill rod in one time, to reduce the number of adding and screw-off drill rod and improve the effective working time.
2. As a result pf crawler chassis drive, the down-up adjustment distance of the rig is 400mm. Hole position adjustment time is greatly reduced.
3. The rig has holder and shackle device. Through operating with the power head chunk, it can reduce operator's labor intensity.
4. As the rig has a hydraulic chuck with inner hole diameter of 110mm, no need to make any alteration on top-drive head, you can adopt a single tube, double tube, three tubes to make jet-grounting, reverse circulation drilling and 108mm pipe-rof construction.
