It is a special machine used for unloading oil pipe threads in oil field workover operations. It is a new product based on the original XYQ3B hydraulic power tongs. This product is driven by a high-torque cycloidal oil motor. The H-type manual reversing valve is directly matched with the oil motor and has a compact structure. It is the lightest tubing pliers in the current hydraulic power tools for workover.

 This product has the following characteristics:

1. The clamp head adopts the advanced clamping mechanism. When the two pipe diameters of 2 3/8", 2 7/8" and 3 1⁄2" are unloaded, there is no need to replace any parts, and the clamping performance is reliable. long lasting.

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.

5. Adjust the oil supply pressure to get the best torque required for the buckle of various steel grades.
