Due to long-term exposure to the natural environment, outdoor single / double girder gantry cranes are easily affected by rain, moisture, salt spray, ultraviolet rays, etc., causing metal parts to rust. To prevent rust, you can take the following measures:
1. High-quality coating: During the crane manufacturing process, high-quality anti-rust paint or coating is used to treat the metal surface. These coatings provide a protective film that isolates the metal from direct contact with the outside environment.
2. Regular inspection and maintenance: Check the crane regularly, especially the coating and metal surface. Once you find that the coating is damaged or rust appears on the metal surface, it should be repaired immediately.
3. Cleaning and maintenance: Clean the crane regularly to remove dust, soil and other pollutants on the surface. Especially in coastal areas, regular cleaning should be done to remove salt, which can accelerate the corrosion of metals.
4. Use of anti-rust oil: For some parts that are difficult to paint, such as hinges, bolts, etc., you can use anti-rust oil to provide additional protection.
5. Maintenance of the drainage system: Ensure that the crane's drainage system is unobstructed to avoid water accumulation that may cause metal parts to be immersed in water for a long time.
6. Covering protection: When the crane is not in use, the crane can be covered with a tarpaulin or other covering to reduce the time of direct exposure to severe weather.
7. Use weather-resistant steel: When designing and building cranes, consider using weather-resistant steel, which contains specific alloying elements that form a protective layer of rust on the surface, thereby slowing down further corrosion.
