Descripción general

The drum is the component used to wrap the wire rope in the hoisting mechanism. The drum, the drum shaft, the flanged inner ring gear, the drum hub, the bearing and the bearing housing form a whole rope drum. Rope drum is usually made of cast iron. However, on special occasions or based on your special requirements, crane rope drum can directly weld with cast steel or steel plate.

According to the shape of the cylinder, the drum can be divided into a long shaft drum and a short shaft drum. According to the manufacturing method, it can be divided into a casting drum and a welding drum. According to whether there is a rope groove on the surface of the cylinder of the drum, it can be divided into a smooth surface and a spiral groove surface drum. According to the number of layers of the wire rope wound on the drum, it can be divided into a single-layer winding drum and a multi-layer winding drum. Crane mostly uses the single-layer winding drum.
