Wire ropes are several strands of metal wire that are twisted into a helix to form a composite rope, known as a laid rope. Large diameter wire rope consists of several strands of rope laid in what is known as cabling. Wire ropes are a complex mechanical device consisting of several moving parts that work together to help support & move an object or load. In the lifting & rigging industries, wire rope is attached to a crane or hoist & fitted with a swivel, shackle, or hook to attach to a load and move it into a controlled case. It can also be used for lifting and lowering elevators or as a means of support for suspension bridges or towers. Wire rope is a preferred lifting tool for many reasons.
Wire rope is made of threads of metal wire that are braided together to form a helix. Due to its heavy, flexible and tough characteristics, as well as being weather- and corrosion-resistant, it is commonly used in the building and construction, engineering, agriculture, aircraft, and marine industries. Each wire strand bringing equal pressure to the bundle contributes to its strength and flexibility, making it an ideal material for pulleys. In Australia, wire rope was made of iron; Today, the materials used are mainly steel.
