In March 2025, a new type of wire rope drum for hoists developed by a certain company was authorized by the National Intellectual Property Administration.
This patent innovatively designs for the pain points of the traditional hoist drum, such as the cumbersome and time-consuming replacement of the outer drum. It is equipped with a unique positioning mechanism and adjustment mechanism in the inner cylinder of the equipment. When it is necessary to replace the worn outer cylinder, the new structure can significantly simplify the operation process, making the disassembly and installation of the outer cylinder more convenient, thereby greatly improving the replacement efficiency.
The application of this technology is expected to reduce the downtime of equipment caused by the replacement of the outer cylinder. It is of great significance for scenarios such as ports, mines, and construction sites where hoists and lifting equipment are frequently used, and can effectively ensure the continuity and economy of production
