YNJ380/35II type screwing machine is a special machine for loading and unloading casings and other threaded joints widely used in oil fields and industrial and mining enterprises.

This product has the following characteristics:

1. The clamp head adopts the advanced four-claw claw clamping mechanism to clamp the workpiece with any outer diameter within the applicable range. It does not need to replace any parts, and the clamping performance is reliable and the service life is long.

2. One gear shifting and large torque.

3. The main and back clamp heads are controlled by multi-way valves, and the multi-way valve can be operated to realize the main and back clamps respectively clamping or loosening the workpiece.

4. The upper and lower shackle reversing can be operated by simply manipulating the manual reversing valve and shifting the knob to the knob.

5. The back clamp is equipped with a hydraulic running mechanism that can move with the workpiece.

6. It can be equipped with automatic torque control system to set, control and record the upper torque value. The torque of the back tongs is indicated by a pressure gauge mounted on the cylinder, and 1 MPa is equivalent to 2 KN.m.
