APPARATUS FOR REPAIRING A TENSION MEMBER
A sheathing repair assembly for a tension member of a post-tensioning tendon, the tension member including a strand and a sheathing layer is disclosed. The sheathing repair assembly includes a repair tube having first and second end portions and a first sealing assembly. The first sealing assembly includes a first nut having a first frustoconical surface and a first forcing element adapted to cooperate with the first frustoconical surface so as to compress the first end portion of the repair tube. The sheathing repair assembly also includes a second sealing assembly having a second nut having a second frustoconical surface and a second forcing element adapted to cooperate with the second frustoconical surface so as to compress the second end portion of the repair tube.
Method and apparatus for locking assemblies
Locking assemblies are provided for connecting to a stranded element. The locking assemblies include a housing with a receiving bore, locking bore, and aperture. The stranded element enters the housing through the receiving bore. A drive shaft can advance a locking element in the locking bore such that the locking element contacts the stranded element to apply a force to secure the stranded element to the locking assembly. Ends of the stranded element can be pushed by the locking element out of the housing through the aperture. The locking assemblies can be used for mechanical and/or electrical connections. Examples of stranded elements include electrical wires, mechanical stranded cables, rope, and other multi-strand materials.
Rope end safety device
A safety apparatus on a rope, comprising a housing for guiding the rope, a clamping mechanism such as a trigger configured to release or clamp the rope against the housing, and a control mechanism, wherein the control mechanism comprises a rope end sensor which is physically displaced by the rope. When rope no longer displaces the rope end sensor, such as when the rope end has passed by the control mechanism, the trigger is biased to an active, clamped position thus halting the rope between the trigger and the housing.
INTEGRATED DROP WIRE CLAMP AND METHOD OF USE
Integrated one-piece drop wire clamps and methods to hold a cable therein. The drop wire clamps comprising a shell with a base portion having a first end and a second end with a longitudinal axis therebetween and opposing side walls extending from the base portion along edges thereof to define a channel therebetween. The side walls are angled with respect to each other and separated by a first distance proximate the first end and a second distance proximate the second end, the second distance smaller than the first distance. The drop wire clamps further include opposing slide wedges disposed within the channel and moveable between a first position and a second position. The side walls bias the slide wedges towards a center of the channel as the slide wedges move from the first position to the second position. Method of securing cable in drop wire clamps also provided.
WIRE ROPE CLAMP ASSEMBLY
A wire rope clamp assembly for use with an elevator is provided. The wire rope clamp includes a first clamp member having an outer side and an inner side. The inner side has a plurality of channels configured to receive one or more suspension members. The plurality of first clamp member channels has a plurality of surface structures configured to engage lays of the one or more suspension members. A second clamp member is configured for attachment to the first clamp member. The second clamp member has an outer side and an inner side. The inner side has a plurality of channels configured to receive the one or more suspension members. The plurality of second clamp member channels has a plurality of surface structures configured to engage lays of the one or more suspension members. The plurality of surface structures for the first and second clamp member channels are multidirectional.

ROPE GRIPPING MEMBER OF A HOISTING APPARATUS, ROPE GRIPPING DEVICE, TERMINAL ARRANGEMENT AND HOISTING APPARATUS
The invention relates to rope gripping member for a rope gripping device, the rope gripping member comprising an elongated rope gripping face for being pressed against an elongated side face of an end section of a rope, the elongated rope gripping face having a longitudinal direction and a front edge and a rear edge; wherein tensile stiffness of the rope gripping member in longitudinal direction of the gripping face increases non-linearly with accelerating rate from the front edge towards the rear edge of the gripping face. The invention also relates to a rope gripping device, a rope terminal arrangement and a hoisting apparatus implementing the rope gripping member.
Method of Terminating a Stranded Synthetic Filament Cable
An apparatus and method for terminating a multi-stranded, non-parallel cable. An anchor is provided on the end of each strand. A collector is provided to link the anchors and connected strands into a single unit. An alignment fixture is provided to transition the strands from the non-parallel lay within the cable to a parallel path adjacent to the anchors.
Connector
The invention relates to a connector (10) for securing a rope (12) to a support structure (54), comprising a sleeve (16) which can be interlockingly and/or frictionally or integrally connected to a support structure element (56), and which has an inner casing surface (18) having at least one region (20) with an inner thread (22) and having at least one further region (24) for guiding a rope, as well as comprising a screw-in sleeve (32) which has an outer thread (34) at least in sections for screwing into the sleeve, and which also has an inner casing surface (36) for guiding a rope. An inner diameter (26) of the region (20) is larger than a further inner diameter (28) of the further region, and the regions are separated from one another at least in sections by a chamfer (30), such that at least one ball element (40) can be positioned between the chamfer, the screw-in sleeve and a rope that can be guided by the sleeve and the screw-in sleeve, and the guidable rope can be secured by means of traction by screwing the screw-in sleeve into the sleeve.
Inverted injection method of affixing a termination to a tensile member
A method for attaching an anchor to an end of a tensile member by inverting the assembly of anchor and tensile member and injecting pressurized potting compound. A length of filaments of the tensile member are placed within a cavity through the anchor. The anchor and filaments are placed in an inverted position, with the distal end of the anchor facing downward and the cable extending upward out of the anchor. If the anchor has an open distal end this is sealed. Liquid potting compound is injected into the anchor cavity and allowed to solidify. During the solidification process, a controlled translation (pulling) of the cable is preferably introduced.
