Features:
1.High construction efficiency. As the rig uses a hydraulic chuck with large inner hole, a fixture 6m drill rod in one time, to reduce the numbers of adding and screw-off drill rod and improve the effective working time.
2.As a result of crawler chassis drive, and the rig mast down or up of position adjustment of 400mm. Hole position adjustment time is greatly reduced.
3.The rig has a holder, shackle device. Through cooperation with the operation of the power head chuck, to reduce the operator's labor intensity.
4.The rig adapt to a wide processes. As the rig has a hydraulic chuck with inner hole diameter of Φ110 mm . No need to make any alteration of top-drive head, you can adapt a single tube, double tube, three tube to make jet-grouting, reverse circulation drilling and Φ108 pipe-roof construction.
