| Maximum stroke of power head | 3500mm |
| Rotary reducer | N/A |
| Push-pull reducer | China brand |
7. Clamp
The drilling rig is equipped with a rotating self-centering clamping and unfastening device, which can clamp the drill rod firmly; The vision is good, and it is also convenient for the maintenance and replacement of the jaws.
| Shackle torque | 20000N·m |
| Shackle rotation angle | 20° |
8. Cab
Rotating noise-proof cab, with adjustable seats, equipped with heating and cooling air- conditioning, which greatly improves the operating comfort of the drilling rig. The internal lighting, windshield wiper, high-end leather seats and other configurations are suitable for operation.
| Cab width | 950mm |
| Cab length | 1200mm |
9. Drill pipes, drilling tools (optional)
Standard oil drill pipe or non-excavation special double top drill pipe can be selected; the back reamer can be fly-cutter reamer, barrel reamer, and fluted reamer. The size of the joints at both ends of the drill pipe is API NC23.
Note: The maximum push-pull force and maximum torque that the drill pipe can withstand cannot reach the maximum at the same time. To avoid sticking during use of the drill pipe, please observe the maximum connection torque limit during the use of the drill pipe.
