Hydraulic bucking unit
The floating backup tong is able to inspect the make-up torque precisely and display the torque of inflection point clearly during the make-up process. It changes speed automatically during the make-up process and the low rotation speed is lower than 5r/min. It is thus applied to the processing demand of premium threads.
1. Hydraulic operation:
2. Master tong and backup tong Synchronous work;
3. Master tong and backup tong fastening the pipe by two way, widely range, and do not replace the accessories;
4. Torque automatic system;
5. Backup tongs can be moved according to the need;
6. Multi-speed shift.
