The casing tong is used to make up and break out for casing operation in oil field. It has greatly reduced the labor of worker, enhanced connection quality of thread and diminihed accidents in inappropriate casing operation. The tong has the following features:
1. Open head type, optimization design;
2. Brake belt assembly,up and down cnetralizing mechanism;
3. Wholly hydraulic mode and mechanical gear shift;
4. Equipped with torque gauge, optional torque control system to display, control and record the make-up torque;
