For the frequently working parts of electric single-girder cranes, you can use No. 10 or No. 20 diesel for painting. This can not only remove substances that easily corrode the equipment, but also form an oil film on the metal surface to protect it. The effect of low temperature. When cleaning and lubricating, it is best to choose calcium-based or lithium-based grease, because they are very effective in maintaining the performance of all aspects of electric single-girder hoisting machinery, and these greases will also be used when the equipment is used again. It will be easier to clear. If the paint film of the metal structure is damaged during the inspection, clean the damaged area and then apply anti-rust paint such as anti-rust paint.
For lifting equipment that has been out of service for a long time, rust prevention is a very important task. The following measures can be taken:
1. First of all, when the equipment is shut down for maintenance, the surface of the entire equipment must be inspected. It is best to ensure that all areas are covered by surface paint film.
2. If during the inspection, it is found that the paint film of the metal structure is damaged in some places, be sure to clean the damaged areas and then apply anti-rust paint such as anti-rust paint. Protect metal surfaces from corrosion due to weather conditions.
3. In the process of rust prevention, the movable parts of the crane cannot be ignored. For these parts, you can use No. 10 or No. 20 diesel for painting.
4. In addition to using diesel for cleaning and lubrication, you also need to apply a layer of lubricating oil.
When the crane leaves the factory, it will be painted to protect the equipment from corrosion. When maintaining the single-girder crane, pay attention to whether the paint on the equipment is missing and repaint it in time.
