A hydraulic torque wrench with a ratchet is used in conjunction with a hydraulic pump. The hydraulic cylinder generates thrust and passes through the crank，It is transferred to the hexagon socket with ratchet device and then to the bolt connection, and the bolt is pre-tightened as required.
1. The pre-tightening torque can be accurately and reliably controlled by the pressure gauge of the hydraulic system
2. Improve the stiffness of threaded connection and reduce the risk of bolt fatigue fracture
3. Can be used for pre-tightening of bolts and internal angle screws
