  • Load-Bearing Ring for Hydraulic Fasteners
    Publication number: 20080267732
    Abstract: Load-bearing ring (120, 220) have segments (121, 122, 221, 222) connected by studs (123) or frangible portions (228), where opposed tapered faces (125, 126, 225, 226) co-operate with complementary faces (114, 115) on hydraulic fasteners (110, 210) on a tapered face (342) on a washer (341), to enable controlled release of the load-bearing rings (110, 210) to enable de-tensioning of a bolt or stud tensioned by the hydraulic fasteners (110, 210, 310).

  • Tensioning hydraulic nuts
    Patent number: 7140824
    Abstract: A hydraulic tensioning system for nuts on studbolts has a puller bar and a puller buddy, which are coupled to the studbolt, and a bridge around the nut. The puller bar is internally coupled to the studbolt (and may engage the nut before the tension is applied). The nut can comprise a cone nut, which cooperates with a complementary collar or shell with a conical inner face and a spherical base washer.

  • Hydraulically assisted fastener element
    Patent number: 5730569
    Abstract: An hydraulically assisted fastener has a pressure means (13) nested in a recess (15) or groove in a nut (11) or a thrust washer with a filler neck (20, 31, 44) whereat a nipple (14) can be used as a means of pumping grease or oil to the pressure means. The pressure means can be a bladder (13) or two parts with mated channels (42, 43). Alternately the pressure means (13) can be a single part with open channel (45) nested in a channel (46) in a nut body or thrust washer.
