YNJ380/35 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 five-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, two-speed shifting, high-speed shifting, low-speed torque.

3. The main and back clamp heads are parallel hydraulic circuits. When the manual reversing valve is operated, the main and back clamps can be synchronously clamped or loosened.

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.
