Main features:

1. The hydraulic clamp consists of main clamp and back-up tong, light and high efficiency.

2. Main clamp and back-up tong make the linkage, it operate manually operated directional valve on the main clamp, the back-up tong can clamp or loosen the tubular pile, flexible and reliable.

3.Top swich high speed and low swich big torque

4. brake disc integration, can clamp the drill rod connect effectively

5. The arrester is on the top of tong head, which makes the service very convenience.

6. hang main clamp, the back-up tong float down the main clamp. The back-up tong connect the main clamp through the quick connector. Easy to use and separate.
