The working environment of the tower crane is relatively poor. It often works under the corrosive gas dust including acid and alkali. In addition, the collision during the operation and the natural aging and falling off of the antirust paint cause the surface to lose protection. In addition, the maintenance work of the tower crane is not timely, resulting in local corrosion and oxidation, varying degrees of surface corrosion, reducing the strength of the steel structure and making the steel structure of the tower crane over time Structural deformation.
