Bolt tensioner for underwater bolt tightening, SUBSEA type
Bolt tensioner BE-HTSS - Japan Plarad
Large underwater bolt tightening tool. It can be easily attached even underwater, significantly reducing bolt tightening work time! Compatible with sizes M20 to M100.
■ The sub-sea type bolt tensioner features a split puller nut that clamps the bolt, allowing for easy installation even in underwater bolt tightening with long protrusions, significantly reducing the time required for bolt tightening work! (Especially effective for long anchor bolts and foundation bolt tightening.) ■ It reduces diver's working time for challenging large bolt tightening tasks underwater. ■ Nickel-plated coating to prevent rust. ■ Multiple bolts can be tightened simultaneously (parallel tightening) by connecting tensioners. ■ Hydraulic specification of 150 MPa, with a maximum pull stroke of 30 mm per operation. ■ It is also highly effective for bolt tightening tasks with long protrusions, beyond underwater bolt tightening work.

basic information
■ The puller nut of the bolt tensioner is split into two parts to clamp the bolt, making it easy to attach even for underwater bolt tightening with a long protrusion, significantly speeding up the tightening work time! (*Especially effective for tightening long anchor bolts and foundation bolts.) ■ Reduces diver's working time for difficult large bolt tightening in underwater and underwater conditions. ■ Nickel-plated coating to prevent rust. ■ Multiple bolts can be tightened simultaneously (parallel tightening) by connecting tensioners. ■ Twin hydraulic couplings / single can be selected. ■ Bolt tensioner with a hydraulic specification of 150 MPa. ■ The longest maximum tensile stroke of the tensioner is 30 mm in one operation. ■ Custom design for special specifications is also available. ■ Can also be used for tightening bolts with a long protrusion for purposes other than underwater bolt tightening.
