Product Description

Model YNJ-200/15 Hydraulic Make- up/Break - out Units is a kind of machine for rnaking up and breaking out thread joint, which is suitable for the

assembly and disassembly of downhole pump, downhole tools, tubing, casing and other thread joint tools. This Product has the following features:

• Unit' head is driven by low speed large torque hydraulic motor. Control valve set connects with the hydraulic motor directly. The structure is compact and

  concise.

• Hydraulic backup tong and units' head are parallel hydraulic circuit. Operating control valve on units' head, backup tong clips or loosens simultaneously

• Units' head and backup tong are four planetary claw of bi-direction clipping mechanism. When clipping tube of various OD in application range,

  just change the direction of knob.

• Automatic Torque Control system can be provided according to the demands of customers. This system can set the best torque value freely,

  control the making-up torque automatically, record each maximum torque value, which can be checked by technical and checkout departments.
