Description

Hoisting device for maintaining port mobile machinery equipment Technical Field The utility model relates to the technical field of maintenance of mechanical equipment, in particular to a lifting device for maintenance of port mobile mechanical equipment. Background In the daily operation of ports, mobile machinery such as cranes, forklifts, loaders and the like take on important tasks such as cargo handling and transportation. These devices are in a high-strength, high-load operating state for a long period of time, and various failures are inevitably caused, and periodic maintenance is required. When servicing port mobile machinery, it is often necessary to disassemble and install large parts of the equipment, which requires the use of lifting devices. The traditional lifting device for maintaining the port flowing mechanical equipment mostly adopts a simple lifting hook and steel wire rope combined mode. The lifting device has a plurality of problems in the actual use process. Firstly, its stability is relatively poor, in the hoist and mount in-process, because harbour environment is complicated, and wind-force, the influence of factors such as ground unevenness and equipment removal take place easily to rock, and lifting hook and wire rope lead to the skew to appear in the spare part of hoist and mount, have not only increased the degree of difficulty of installation and dismantlement, still have great potential safety hazard, easily initiate accidents such as spare part drops, cause the harm to maintenance personal's personal safety and equipment.
