2 Legged Wire Rope Sling has several strands of metal wire which are twisted into a helix forming a composite rope, in a pattern known as "laid rope" and larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as "cable laid". The sling provides friction between the individual wires and strands which causes wear over the life of the rope. Furthermore, it also helps to make up for minor failures in the short run. 2 Legged Wire Rope Sling are used dynamically for lifting and hoisting in cranes and elevators for transmission of mechanical power. Wire rope is also used to transmit force in performances.
