Wire rope is a rope formed of twisted strands of wire, usually laid over a core. Initially, wire ropes were made from wrought iron but steel is mainly used to construct them today. They have multiple uses, such as hoisting elevators and cranes and supporting suspension bridges, to name a few.
The German mining administrator and engineer Wilhelm August Julius Albert invented the wire rope in 1834. Before his experimentation, his mine used hemp ropes (for which the hemp was imported) and chains (which were cumbersome). Here is an illustration of his wire rope that he constructed from wrought iron which had a diameter of 18 millimetres and was made of 3 strands with 4 wires each which had a diameter of 3.66 millimetres:
