Characteristics：

This tong simplifies hydraulic system uses pneumatic and hydraulic united controlled system, enhancing the work reliability.

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

prevent it slipping in neck.

This tong adopt flexible floating mechanism, making hoist simplified and automatically centered

clipping mechanism can assure the their work reliability.

Enhanced tong body and safety door restrain deformation at large torque with effectively.

The connection of unique ramp and wedge block makes assembly and removal very convenient.

The pneumatic tyre clutch shifting without pause enable the torque and speed can be controlled

conveniently.

What's more, positive and negative direction all cangenerate maximum torque and speed.

We can use hydraulic hanger to adjust the height of tong body and impel cylinder to regulate the

position without labor force.
