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 rope severing guard is engageable around a rope or flexible member to protect it from severing by a chainsaw cutting chain. The guard has a flexible body having a rope passage through which a protected rope is positioned. An interior cavity in the body of the rope severing guard is filled flexible fibers which if contacted by a moving cutting chain of a chainsaw, will form clogging engagements with the cutting chain and the chain support it moves upon or with the cutting chain and the motor drive gear powering it.

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.

A structural cable of a construction work. The structural cable including a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, a housing located within the sheath and fixed relative to the sheath, said housing defining a cavity, the bundle of tendons being at a distance from the housing and the cavity, the bundle of tendons being located outside the housing and the cavity, said cavity extending longitudinally relative to the sheath.

An assembly and method for using a flexible tensile member as part of the rigging for a heavy machine such as those used in the mining industry. The inventive tensile member includes a core surrounded by a separate armor layer. The armor layer assumes various forms, including a hollow cylinder having a substantial wall thickness. The core produces excellent strength in tension (and with a substantial reduction in weight). The armor layer protects the core from external blows and forces produced by the weight of the other parts of the machine's rigging and the hostile environment in which the machine operates.

The present invention relates to a rope assembly (1) consisting of at least one rope (2) that is made of textile fibre material and is folded back to form two substantially parallel rope portions (2, 2), wherein load distribution between the two rope portions is enabled and the rope portions are surrounded by a common sleeve (4). The rope assembly according to the invention is particularly suitable as a winch rope or as a rope for drive pulley drives, e.g., as a lift cable, in Koepe hoists and in capstans.

Embodiments of the knife cut resistant sleeve comprise a spring enclosed by a cut resistant material. The knife cut resistant sleeve is configured to be placed onto a rope of varying sizes and protect the rope from sharp objects. Embodiments of the knife cut resistant sleeve use cut resistant material and can be capable of rotation when hit by a knife in order to prevent the rope from being cut. The sleeve is configured to provide the correct amount of coverage on the rope depending on the length of the rope.

The structural cable (10) comprises a bundle of load-bearing tendons (15) extending between upper and lower anchoring devices, a first sheath (20) containing the bundle of tendons, and a second sheath (22) arranged around the first sheath, with a gap between the first and second sheaths.

A structural cable of a construction work. The structural cable comprises: a bundle of load-bearing tendons (20), a first sheath (26) containing the bundle of tendons, a second sheath (28) arranged around the first sheath, the second sheath comprising windows (31), and a plurality of light-radiating modules (46) configured to radiate light, each light-radiating module being arranged within the structural cable to radiate light through at least one window outwardly relative to the structural cable.
