The lifting speed is fast, and the crane is required to be able to fully rotate. The development of marine engineering cranes requires its performance to be more and more superior and the form to be more and more simple. These requirements have put forward severe tests for the design and manufacture of the crane wire rope hoisting mechanism. In order to achieve large lifting capacity and large lifting height, the wire rope hoisting mechanism usually has a larger diameter, and uses a multi-layer winding of a folding line reel, and the reel size is larger.
