API 7K Casing Power Tong for Workover

API 7K Casing Power Tong for Workover

Casing power tongs are widely used for making up and breaking out of casings or pipes. The casing power tong features high efficiency, safety, reliability, labor saving and ensures connection quality. Tong head is designed as open and equipped with advanced swing type double jaw assembly, which can secure reliable clamping. This series of casing tongs can be configured with torque device to perform computer monitoring and managing on pressure, torque and rounds. The casing tons are designed and manufactured according to API 7K.

Features:

1. Opening type, convenient and prompt to enter and slide off the working position, with an integral tong head of great strength and rigidity.

2. Double swing head jaws, very convenient to assemble and disassemble, with the best design for tangent-diameter ratio, ensuring the reliability of gripping and easy backslide.

3. Band brake of great moment, easy to operate and convenient to maintain and replace.

4. Notched gear support structure, greatly improving the strength and rigidity.

5. TQ340-35 has three gear shifts with double-rowed planet gear. The unique way of shifting with air tyre clutch without stopping the tong avoids the defect of the general tong that the motor has to stop when putting into the dies so that there is less time efficiency.

6. The gear motor is produced with special technology and structure, and increases its torque by 20%.

7. The case is thickened with manganese steel. The jaws are cast with precise technology, artistic and strong.

8. The hydraulic torque gauge as well as the joint for a round – torque gauge makes it possible for computers to manage the process.
