Torque Wrench High Cycle (TWHC)

Description: The TWHC torque wrench is a ratchet-type torque tool used in conjunction with 

standard impact sockets to hydraulically tighten nuts and bolts. It is powered using a 690 bar 

(10,000 psi) hydraulic pump unit.  The torque output from the TWHC torque wrench is proportional 

to the pump-pressure applied.
