A structural spanning system that may be embodied by a cable array bridge system, which typically includes a pair of inclined towers separated by a horizontal distance spanned by a bridge deck and oriented at an outward angle. On opposing ends of the central bridge deck, the towers, and/or columns are secured at a common fulcrum. The columns are similarly oriented at an angle relative to a horizontal plane between fulcrums. Upper cables between towers extend to the deck and create a perpendicular force vector where they connect and are tensioned across the shallow arch bridge deck. Lower cables extend between opposing inclined columns, with one or more stringer cables extending between the lower cables and the bridge deck. Securing the lower cables to the deck via the stringer cables stabilizes the deck in tension by a counterforce to the upper cables. As a result, the bridge deck experiences a balanced pre-stress of upper cable forces in tension through the network of cables.

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.

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 deicing device for a sheath of a structural cable, the structural cable comprising tendons housed in the sheath, the deicing device includes a base; a bearing element; and a power system configured to press the bearing element against the tendons while the base is in contact with an inner surface of the sheath, and to generate vibrations between the bearing element and the base.

A platform and method for erecting a platform of support beams to which decking is applied so that it is suspended from at least one main cable of a bridge. Spaced slings are applied to the main cable so that each extends around the main cable. Ends of each of the slings are attached to a respective one of the support beams respectively. One end of a guy in the form of a cable is attached to at least one of the slings intermediate ends thereof. The guy is extended between the sling and an anchor point to restrain the sling from slippage along the length of the main cable.

A preassembled parallel wire cable creates a random cast of loops. Any of the random cast of loops is hung for transport, thus eliminating costly and time-consuming coiling and reeling operations.
