Bolt tensioner for underwater bolt tightening, SUBSEA type
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.
