Spring Return Tensioners

Features a spring-assisted piston and fits all standard Oil and Gas Flanges.

Spring Return Tensioners

TSR tensioners have been developed to improve productivity and operator safety. Their spring return mechanism provides automatic piston retraction after depressing the system at the end of the tensioning sequence. This ensures the tools are ready for the next operational sequence of tensioning, commencing from zero stroke.
The design of the tool is ideally suited for use on common flange sizes. The geometry of the tool and high load tool capacity ensures that the location is assured and loading of the bolting application is easily achieved.
