[0002] The bridge crane is a crane used for loading and unloading operations at the dock. It is the heart of the dock. The operating capacity of the bridge crane determines the cargo handling capacity of a dock. As a large-scale port lifting equipment operating outside, the bridge crane has a long-term exposure to the air. The surface of the steel structure will be in direct contact with other chemical corrosive media in the air, and the protective paint layer will gradually lose its protective ability and rust. In order to extend the service life of the beam structure and ensure the safe operation of the bridge crane, the rusted surface on the beam steel structure needs to be regularly derusted.

[0003] At present, the rust removal method commonly adopted by major domestic port enterprises is mostly manual grinding and rust removal, but manual grinding and rust removal often has disadvantages such as low rust removal efficiency, rust residue damaging the health of workers, and safety hazards in high-altitude operations.
