The SBT imperial range of hydraulic bolt tensioners is designed primarily for topside operations and features spring assisted return hydraulic piston which reduces bolt tensioning cycle times considerably. Once the hydraulic pressure is released, the tensioner piston automatically starts to retract, thus removing the need to manually wind down the threaded puller. The range currently comprises of 22 models, suitable for standard size bolts from 1¼” to 4” diameter.

The SBT range can be operated with a variety of interchangeable threaded pullers and nut rotating sockets available, either as bolt size conversion kits or individual parts. All SBT bolt tensioners are designed and manufactured with a wear coated piston, maximum stroke indicator, self energising high pressure seals, dual quick connect couplers, for easy multiple tensioner hook up and operate at pressures up to 1500 bar maximum.

Customised and special design tensioners are available on request

Note: Weight is for load cell and bridge only. Total weight of complete assembly depends on size of puller and nut rotating socket selected. Tommy bars are not included. Hi-Force recommends one tommy bar for every four tensioners.
