Reasons for the peeling of the paint coating on the surface of cranes – geometry
Thread Content
Generally speaking, when a crane leaves the factory, its paint coating on the surface should be intact. However, after being used for a period of time, the paint coating on the surface of the crane begins to peel off due to the following reasons. 1. External impact or scraping: If a surface of a crane is subjected to severe external impact or scraping, the paint coating on that surface may peel off or develop scratches as a result of this damage. 2. Repeated disassembly and assembly of components: For example, metal covers on cranes are sometimes subject to repeated disassembly and assembly, which can easily lead to the peeling of the paint coating due to collisions or scratches between tools and components. 3. Impact of vibration or strong air currents: Over time, cranes that are in use experience severe vibration during operation, as well as continuous impact from strong air currents; as a result, the paint coating on their surfaces gradually loosens and peels off. 4. If the crane fails to comply with the required manufacturing procedures during the painting process, or if the quality of the paint used is substandard, this can also lead to the paint coating on the surface peeling off after the crane has been in use for some time.
