What are the features of hydraulic power tongs?

Hydraulic power tongs are designed and manufactured according to the People's Republic of China oil and gas industry standard SY/T5074-2004 “Power Tongs for Oil Drilling and Well Repair”. It is a kind of open type power clamp. It is a mechanized equipment used for loading and unloading oil pipe and similar pipe threads in oilfield well repairing operation.

This type of hydraulic power tongs has the following features:

1. The main clamp is driven by a low-speed high-torque hydraulic motor, manual reversing valve and hydraulic motor directly matched. The structure is simple, compact and lightweight.

2. Hydraulic back clamp and the main clamp composed of a combination of clamp, operation of the main clamp on the manual reversing valve, back clamp and the main clamp synchronized automatic clamping or loosening of the pipe column.

3. The head of the main and back clamp are internal surface roller climbing two-way clamping mechanism, reversing the fixture only the main and back clamp on the steering knob can be rotated 180 degrees.

4. According to user needs, the power clamp can also be equipped with a relief valve, in the hydraulic system pressure is higher than the rated pressure of the power clamp or the hydraulic system relief valve failure to play a role in overload protection.

5. According to user needs, the power clamp can also be equipped with a special torque pressure gauge, real-time monitoring of the power clamp torque output.

6. Clamp head opening with automatic opening and closing of the safety gate, when working to play a safe protection.
