This hydraulic power tong is a special machine used for oil discharge pipe thread in oil field workover. This product is driven by high torque cycloidal oil motor. H type manual directional valve is directly matched with oil motor. It is compact and is At present, the hydraulic power tongs for workovers are medium-sized tubing tongs.

 This product has the following characteristics:

1. The clamp head adopts advanced clamping mechanism, which has reliable clamping performance and long service life.

2, the two-speed shifting step is large, the high-speed is fast, and the low-speed torque is large.

3. The clamp head brake mechanism is placed on the upper cover of the clamp head, which is very convenient for adjustment and maintenance.

4. The new hydraulic backing pliers and the main pliers form a combination pliers, and the manual reversing valve on the main pliers is operated. The back pliers are synchronously clamped or synchronized with the main pliers to loosen the pipe string, and the action is flexible and reliable.
