Steel Wire Cable

- Jan 25, 2019-

Cable, also called wire rope, in engineering, either an assemblage of three or more ropes twisted together for extra strength or a rope made by twisting together several strands of metal wire.


The first successful stranded iron wire rope was developed in 1831–34 by Wilhelm Albert, a mining official of Clausthal in the Harz Mountains in Saxony. Even when first tried for hauling and hoisting in his mine, it proved so superior to hemp rope in serviceability and cost that its use soon became widespread in European mining. This stranded wire rope consisted of a number of pieces of wire twisted together to form a wire strand. Several individual wire strands were in turn twisted together to form a wire rope. Albert’s first wire rope measured 600 metres (1,968.5 feet) in length and was installed in the Caroline pit of Clausthal in July 1834. Some 18 wire ropes had been constructed by 1838 and put to use in mining operations in the Harz region. Prior to this advancement, wire rope had already been made in the form of a selvage cable—a bundle of individual wires stretched out into a long length and arranged parallel to one another, then bound together and covered with tarred hemp yarns. High-tensile steel wire was introduced during the 1880s, and steel is now the predominant metal used for wire rope (see also tensile strength).
