Bolt tensioner for underwater bolt tightening, SUBSEA type
Bolt tensioner BE-HTSS, Japan Plarad
Large bolt tightening tool for underwater and in-water use. 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 shortens the diver's working time for challenging large bolt tightening tasks underwater. ■ Designed with nickel plating 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 also excels in applications other than underwater bolt tightening, particularly for long bolt tightening tasks.
