Hydraulic Torque Wrench Operation

Hydraulic torque wrenches are designed  to tighten or loosen fasteners which  require large amounts of force to  achieve the proper preload in contrast  to hydraulic tensioning devices which  directly stretch a bolt these wrenches  apply a turning force or torque to a nut  or bolt head which causes the bolt  thread to advance some hydraulic torque  wrenches use impact sockets while low  clearance wrenches use interchangeable  heads for different nut sizes this video  describes the operation of a typical  system.

Systems may vary so it is  important to use the specific operating  instructions for the wrench and pump  that you are using a typical system  consists of a wrench body sockets or  heads hoses and a source of hydraulic pressure be sure that all parts of the  system meet the specifications of the  wrench manufacturer inspect all  components for damage before use to  begin inspect the hoses and make sure  that the fittings are clean and tight  dirt and debris in the system may damage.

The pump valves or wrench loose fittings  may leak or burst if a leak occurs shut  off the pump and depressurize the system  never grasp a leaking hose the  pressurized fluid may cause serious  injury choose the proper size socket or  wrench head...
