What type of wire rope is used on cranes

Steel wires for wire ropes are normally made of non-alloy carbon steel with a carbon content of 0.4 to 0.95%. The very high strength of the rope wires enables wire ropes to support large tensile forces and to run over sheaves with relatively small diameters.

Cable construction is the combination and arrangement of wires in a rope. Many individual steel wires are helically-laid together to form a wire rope. A strand is when two or more wires are wound concentrically in a helix. These strands are typically wound around a center wire and then around the core.

The term cable is often used interchangeably with wire rope. However, in general, wire rope refers to diameters larger than 3/8 inch. Sizes smaller than this are designated as cable or cords. Two or more wires concentrically laid around a center wire is called a strand.
