Distinguishing feature

The pliers adopt an advanced clamping mechanism. When removing two tubing threads with a diameter of 2 7⁄8" and 3 1⁄2", the main and back pliers do not need to replace any parts. The clamping performance is reliable and long service life.

The difference between the two gears is large, the high-speed speed is fast, and the low gear torque is large.

The clamp brake mechanism is arranged on the clamp cover plate, which is very convenient for adjustment and maintenance.

The new liquid back pliers are matched with the main pliers to form a combination pliers to operate the manual reversal valve on the main pliers. The back pliers are clamped or loosened synchronously with the main pliers, and the action is flexible and reliable.

By adjusting the oil supply pressure, you can get the best torque required when buckling the tubing of various steel grades.

This product has many national patents.
