Corrosion poses a great threat to marine cranes, not only causing early damage but also affecting operational performance and even leading to accidents. While emphasizing the importance of rust prevention for marine cranes, is there a regular pattern of corrosion on crane steel structures?
According to the National Marine Crane Equipment Testing Center, the general rules of corrosion in crane steel structures are as follows, which I would like to share with you:
1. Failure to apply protective paint or poor paint quality, and the corrosion rate of crane steel structures in the atmosphere varies from year to year, initially faster and gradually slowing down later.
2. When deck cranes operate in different regions, the degree of atmospheric corrosion on steel structures varies greatly, and corrosion is more pronounced in coastal and heavily polluted areas.
3. Ship crane working in the same area, due to the influence of the season, severe rusting occurs during the rainy season.
4. The corrosion rate of ship cranes steel structures with painted or electroplated layers is 5 times slower than that without rust prevention layers.
5. The corrosion rate of outdoor offshore crane steel structures is about four times that of indoor ones.
By understanding the patterns of rusting, we can start from the above five aspects to prevent rusting. For example, the fifth point is that rusting occurs faster outdoors than indoors.
Therefore, should we consider some protective measures when operating outdoors? Cover with rain or paint?
Everyone may use different methods based on their own experience and common sense to summarize their experience and provide better protection for lifting machinery.
