Main Features of DF-H-4 full hydraulic core rig with good quality

1. The feeding and lifting of rotator are driven in the structure of cylinder directly pushing, with a 3.5m (11.5 feet) stroke.

2. The rotation of spindle is driven by a single engine. It has four mechanical shifts of range of speeds, and the speed could be adjusted hydraulically with steeples change.

3. The hydraulic geological drill rig is simple in structure. It is light and easy for move.

4. The mast has the functions of sliding and touching ground; the spindle lifted and lowered with hydraulic oil cylinder. It could be folded for transporting and storing.

5. The spindle has a big diameter hole. The spindle has high-precision structure.
