Distinguishing feature

The joint liquid-gas control system is adopted to enhance the reliability of the work.

The upper and lower clamp combination structure avoids the possibility of the drill string bending under the action of high torque and prevents the drill string from slipping in the tile.

This pliers adopts a lightweight and flexible pliers floating scheme, which greatly simplifies lifting; the automatic middle clamping mechanism can ensure that the new and old joints are tight and reliable.

The enhanced clamp body and safety door effectively limit the deformation of the clamp during high torque operation.

The unique sloping plate and wedge block connection structure in the clamp head is very convenient for disassembly and maintenance.

The pneumatic tire clutch does not stop gear shifting mechanism, which is easy to operate, the torque and rotation speed can be controlled, and the maximum torque and rotation speed can be generated in both the front and back directions.

It is equipped with a large-path manual reversing pressure regulating valve, which realizes large torque automatic load unloading and effectively protects the wire buckle of the drill string joint.

The height of the lifting pliers is used to push the cylinder to the position of the pliers without the need for manpower displacement clamps.
