DAVENTRY, United Kingdom — Hi-Force recently added to its range of SBT spring-assisted return bolt tensioners. Now available with imperial bolt sizes of 1.25 inches to 4 inches and metric bolt sizes of M30 to M100, the SBT range consists of 22 imperial and 26 metric models, each with a maximum working pressure of 1,500 bar.
Hi-Force’s SBT range offers all of the features of the standard STS range of bolt tensioners, however, with 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.
