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.

Method and apparatus for producing a synthetic tensile member with a precise length and enhanced stability
A method for producing a synthetic tensile member having a precisely known and stable length. The invention, also comprises equipment configured to carry out the method. A tensile member is prepared by attaching terminations to an assembly of synthetic filaments. The tensile member is then attached to a loading apparatus that subjects the tensile member to a pre-defined loading process. The tensile member is thereby conditioned to a stable length. The length is then measured and a length adjusting component is incorporated into the tensile member to create a precise and stabilized length that is configured for the tensile member's particular application.
Prestressing cable, in particular for static structures
A prestressing cable, in particular for static structures, that includes a longitudinal element and connection elements at the end faces of the longitudinal element. The longitudinal element has stranded wires, the end faces of which are anchored into the connection elements. The prestressing cable includes approximately parallel strands, each of which has stranded wires. The wires are spread apart at their end faces in the funnel-shaped opening of the respective connection element and anchored by a casting process, wherein the frustum-shaped funnel widens away from the strands.
SHEATHING ELEMENT AND METHOD FOR SPLICING A ROPE
A sheathing element, in particular a splicing tape, has at least one sheathing portion which is configured for an at least section-wise sheathing of at least one insertion end of at least one splice, embodied as a long splice, for a rope, in particular for a wire rope, advantageously for a haul rope and/or a traction rope, having a diameter d and a number of N stranded longitudinal elements, in particular strands, wherein
the sheathing portion is suitable for permitting the splice to be produced with a length of less than 100*N*d.
Methods and designs for balancing a stranded termination assembly
Devices and methods for loading a cable in order to create a desired distribution of the load among the cable's constituent strands. Strand terminations are applied to manyand possibly all ofthe cable's strands. The ultimate goal is to connect the strand terminations to a collector in order to create an overall cable termination. The relationship between each strand termination and the collector is allowed to float using the inventive process while the cable is tensioned and an appropriate spatial relationship between each strand tensioner and the collector is determined. Once the appropriate relationship is found, it is configured to be repeatable (such as by recording its position for later application to the same or similar collector).
COVER FOR ROPE OR CABLE LOOP END
A device configured for attachment to a loop end of a recovery winch rope or cable includes a hood element configured to fit over and around the loop end of the recovery winch rope or cable, wherein the hood element covers outward facing surfaces of the loop end, orifices located on either side of the hood element and aligned with an opening in the loop end, such that a continuous open space extends through the opening of the loop end, a base coupled to the hood element, the base being sized to prevent passage through a fairlead of the recovery winch, a removable cap located in the base, wherein the cap includes a space that allows the rope or cable to extend therethrough, and, wherein the hood element, the base and cap are composed of an elastomeric polymer.
CABLE SECTION AND METHOD FOR SPLICING A CABLE WHICH FORMS A PERSON TRANSPORTING WIRE CABLE
A rope portion of a rope that forms a person transporting wire rope having a diameter d, in particular of an endless rope, having at least one splice which is embodied as a long splice and which has a plurality of stranded longitudinal elements, in particular strands, at least one of which has at least one insertion end which at least portion-wise is inserted, in particular in place of a core, between other longitudinal elements, wherein the person transporting wire rope and/or the stranded longitudinal elements are at least largely free of a sheathing that at least partially encompasses the person transporting wire rope and/or at least one stranded longitudinal element.
String, rope, or strap with repetitively spaced holes/flexible-eyelets
A string, rope, or strap with repetitively spaced openings/flexible eyelets from bifurcated braiding or weaving, or from cutting and sealing. The bifurcated openings are preferably created from a single rope or strap that is subsequently braided or weaved into two strings, ropes, or straps and then back into one. The frequent and periodic placement of these eyelets on the string, rope, or strap, allows the user to easily tie down items. The rope or strap is flexible enough to pull it in on its self, through its eyelets. The ends of the string, rope, or strap are finished into a hard tip.
STRANDED CABLE WEDGE
A split wedge body, which has a curved inner surface, is formed gradually thicker from a tip portion to a terminal end portion thereof, and is made to cover the outer peripheral surface of a CFRP cable to thereby enclose the outer peripheral surface of the CFRP cable over a prescribed length thereof. A gap extending in the longitudinal direction is assured between end faces that oppose each other when a plurality of the split wedge bodies are arranged on the outer peripheral surface of the CFRP cable. The gap has an inclined portion that runs along a valley of the CFRP cable enclosed by the split wedge bodies.
