The multi-stage bolt tensioning device is used to generate high prestressing forces using small outside diameter.
This tool is mainly used in the field of turbines, large bearings and pumps. Also in many different industrial applications.
SLT Series Spring Return Bolt Tensioner
TRITORC SLT range offers the added feature of spring assisted return hydraulic pistons.
Designed primarily for topside operation, the additional feature of spring assisted return reduces bolt tensioning cycle times considerably, as the tensioner piston automatically retracts immediately after the hydraulic pressure is released, thus removing the need to manually wind down the threaded puller.
