The PS tensioner provides a simple, safe, accurate and time saving method for tightening bolts and studs, maximising economy and versatility with the interchangeability of adapter kits (bridges, nut rotating disc and puller sleeve). This enables a number of different bolt sizes to be tensioned using a single load cell.

A relief valve has been incorporated into the piston to prevent overstroking, thus eliminating seal damage and improving operator safety.
