Crane is a kind of mechanical machine, usually equipped with sheaves, wire ropes, or chains, and a crane hoist, which is used to move and lift objects vertically and horizontally.

Ropes are formed from natural and synthetic materials, as well as metals such as steel. Petrochemicals and modest amounts of polymeric compounds are utilised as basic materials for synthetic ropes. Synthetic ropes are more resilient and lightweight than traditional ropes. Because of qualities like as bend fatigue durability, high strength-to-weight ratio, and robust spooling capabilities, synthetic ropes are frequently employed in a variety of crane applications.
