Characteristics：

This tong adopts hydraulic and pneumatic control system so it enhances working reliability.

Upper tong integrates with lower tong to avoid twisting drill pipe bent in big torque operation and

to prevent slipping in caliper.

This tong has adopted flexible and lighter floating tong head so that the handling is easy and

simple, the automatic centralizing mechanism could ensure clamping new or old joint reliable.

The enhanced tong body and safety door could prevent tong head from deformation during

large torqueoperation.

The special ramp in the tong head and wedge piece connection structure make the

maintenance simpleand easy.

Operation is easy and simple with pneumatic tyre clutch non-stop shifting mechanism, Torque

and speed can be controlled. It can get the biggest torque and the highest speed in clockwise

or counter-clockwise.

This tong has equipped hand control and adjusting valve with big diameter hose, so it could

unloadautomatically during large torque and protect the drill pipe joint screw efficiently.

 This tong has adopted hydraulic lift to raise or decrease the height of tong itself, the moving cylinder could move the

tong position so it could save labor.
