With the pollution of atmospheric environment and the use of mechanical equipment in the open air, the corrosion problem has always been a very serious problem, which should be considered by everyone. Port cranes are generally used in the open air, so corrosion maintenance is a very important work in the process of use. There are several precautions to prevent corrosion. First, in the process of use, if the paint film on the metal structure is found to be damaged, it should be cleaned first and coated with antirust paint and decorative paint film to ensure that it will not rust in rainy and snowy days.
Second, for its moving parts and connecting parts, anti-corrosion work should also be done well. Oil film can be produced on the surface of metal, which can resist temperature change and damage. The manufacturer told you that after using diesel oil for cleaning and lubrication, you should apply a layer of grease. Calcium based or lithium based grease is a good choice, with strong mechanical stability and water resistance. When applying grease, you should pay attention not to apply it very thick.
