The corrosion of the crane's steel structure is mainly due to the protection measures not doing well enough and being exposed to the air for years and years. When the steel structure of the crane is exposed to liquids or gases in the surrounding environment, it is generated. Some chemical reactions caused damage. Especially when the air in the surrounding environment is filled with all kinds of chemically corrosive media, the rust situation will be more serious. Even if the steel structure of the crane has been painted with a painted layer as a protective surface, when it is used for a long period of time, it will withstand various climates such as heat, cold, moisture and collisions. The lacquer layer will gradually lose its original protection performance due to some external destructive properties. If the steel structure protection measures of the crane are not done well enough at this time, the corrosion effect will intensify. The rigidity and strength of the steel structure of the crane have a great influence, and will gradually reduce the safety, reliability and service life. Therefore, the anti-corrosion measures for the steel structure of the crane must be done well, and the potential safety hazards brought by the corrosion should be eliminated. The hidden safety hazards of the steel structure of cranes are not only reflected in the significant reduction in the thickness of the surface of the steel structure, but also the occurrence of a large number of rust pits, which has long caused a local increase in stress, making the steel Some structural damage occurred early. If the corrosion of the steel structure of the crane is severe, it will directly reduce the safety of the hoisting work, and it may cause accidents such as a collapse or the like during the construction work of the crane. The worst case scenario is There have been major incidents of casualties. When the cranes are hoisted in different environments, the erosion of the steel structure is also different. The air pollution is more serious and the corrosion effect of the coastal areas is more obvious. However, the quality of the lacquer quality of the steel lacquer lacquer painted or there is no protective lacquer, resulting in the corrosion process of the steel structure of the crane in the atmosphere every year will have different speeds.
