A parallel wire cable is produced from a plurality of wires arranged in a bundle for use as a structural cable. Each wire in the plurality of wires is parallel to every other wire in the bundle, and each wire in the plurality of wires is tensioned to a tension value.

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.

A snow and ice melt system having one or more zones, each including one or more heaters, and having one or more controllers configured to use a power output of each heater and an average temperature of each zone to determine operational control of each heater to achieve a specified result. Hydronic or resistive heaters could be used. The controllers may be configured to use a system temperature response over time to determine if a phase change of the snow or ice is occurring. The phase change might indicate that snow or ice is present on a zone and is melting. Use of a first derivative of the system temperature response over time might determine a percentage of a zone covered by snow or ice. Use of a second derivative of the system temperature response over time might determine whether melting is complete.

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.

The structural cable comprises a bundle of load-bearing tendons extending between upper and lower anchoring devices, a first sheath containing the bundle of tendons, and a second sheath arranged around the first sheath, with a gap between the first and second sheaths.

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 device to protect a structural member against a cutting threat, such as a saw blade or thermal cutting device, is provided. The device provides a substrate having a cavity disposed therein. A cutting resistant element is disposed within the cavity to impede cutting of a cutting device, such as a saw blade or thermal cutting device, into the cutting resistant element.
