The structural cable of a construction work comprises a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, and at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

A braided textile sleeve having a flexible, seamless, reflective tubular wall and method of construction thereof are provided. The tubular wall extends along a longitudinal axis between opposite open ends and includes a first set of yarns and a second set of yarns braided with one another. The first and second yarns are provided as different types of yarns from one another and are braided in opposite helical directions with one another. The tubular wall includes a third set of yarns captured between the first and second sets of yarns, with the third set of yarns extending substantially parallel to the longitudinal axis. The sleeve includes a reflective outer layer fixed to an outer surface of the braided yarns.

Disclosed is a non-steel strength membered high strength cable easily monitored for heat and elongation comprising a length of a core-cable (10), the length of core-cable (10) including at least two fiber-optic conductors (2) that are: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material.
One fiber-optic conductor capable of transmitting at least Raman backscattering and the other fiber-optic conductor capable of transmitting at least Brillouin scattering.

A combination of the cable (10): (i) with an interrogator that can read and interpret Raman backscattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Raman backscattering; and (ii) another interrogator that can read and interpret Brillouin scattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Brillouin scattering;
permits ascertaining the elongation of the cable, without using loose tube fiber-opticplacement.

A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.

Present invention relates to a pipe (5) for stay cable and a method for tightening the pipe (5) using stressing means (10). The pipe (5) comprises a tubular shaped wall having an interior and an exterior surface, wherein stressing means (10) are provided to the exterior surface of the tubular shaped wall of the pipe (5), wherein the stressing means (10) are configured in a way to exert a compression force around the tubular shape wall of the pipe (5) longitudinally.

The invention relates to a rope made of textile fiber material, comprising a rope core and a sheath surrounding the rope core, wherein the sheath, an intermediate sheath located between the sheath and the rope core and/or a reinforcement located between the sheath and the rope core comprise(s) a twine of excess length, the twine of excess length being formed in that it comprises at least a first yarn and a second yarn which are twisted together, the first yarn having a greater length than the second yarn, measured in an untwisted state of a unit length of the twine. In a further aspect, the invention relates to a method of manufacturing a twine of excess length for the above-mentioned rope.

A system for protecting a climbing device from contacting a wall includes a barrier device defining an eyelet, an anchor anchored to the wall, and a cord. The barrier device is configured to wrap around the climbing device such that the barrier device extends between climbing device and the wall and forms a sleeve that encircles the climbing device. The barrier device protects the climbing device from the wall. The cord extends through the eyelet and is coupled to the barrier device and the anchor such that the barrier device is anchored to the wall and in a desired position relative to the wall. The barrier device is configured to move relative to the climbing device, and the cord limits movement of the barrier device relative to the climbing device.

The present invention relates to a mooring rope for use in subsea mooring, or a substantially synthetic rope thereof, said synthetic rope comprising a rope core and a layered shell arranged around the rope core, said the shell having a braided outer shell layer. The shell comprises sub-surface buoyancy elements, suitable for use in a subsea environment, extending in radial direction between the rope core and the outer shell.

The method for manufacturing an individually sheathed strand comprises: conveying a group of metal wires through a die; upstream of the die, applying a first filler product to at least a first portion of the strand; upstream of the die, applying a second filler product to at least a second portion of the strand distinct from the first portion; and extruding a plastic around the group of metal wires passing through the die, so as to envelop the group of metal wires covered with the first and second filler products in a continuous sheath formed of the extruded plastic. The second filler product has greater adhesion to the group of metal wires than the first filler product.
