[0002] A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machinery.

[0003] Wire rope is an important component of lifting equipment. When performing lifting work, the wire rope must be correctly wound onto the winch drum to smoothly carry out the operation. However, since the lifting rope will swing with the hoisted object during the lifting process, it cannot be accurately wound into the rope groove, which will cause the wire to wear faster and need to be replaced frequently. In order to solve the above problems, a bridge crane wire rope retracting and releasing device is proposed. Utility Model Content
