How to prevent rust when single beam crane is not used for a long time

Some companies that have installed single-girder cranes may cause single-girder cranes to not work for a long time due to factors such as corporate adjustments. If they are not used for a long time, how to do anti-rust work for electric single-girder cranes?

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 those substances that are easy to corrode the equipment, but also form an oil film on the metal surface. To resist the role of low temperature. When cleaning and lubricating, it is best to choose calcium-based or lithium-based grease, because they have a good effect on maintaining the performance of all aspects of electric single-girder hoisting machinery, and when the equipment is used again, these greases will also It will be easier to clear. During the inspection process, if the paint film of the metal structure is damaged, clean these damaged areas, and then apply anti-rust paint and other anti-rust paints.

For the lifting equipment that has been down for a long time, rust prevention is a very important job. So for crane equipment such as metallurgical cranes and gantry cranes, how do they perform anti-rust work when they have been placed for a long time?

1. When the equipment is to be shut down for maintenance, the surface of the entire equipment must be inspected. It is best to ensure that all places are covered with paint film on the surface.

2. If, during the inspection, the paint film of the metal structure is found to be damaged in some places, then these damaged places must be cleaned, and then anti-rust paint and other anti-rust paints should be applied to these places. Protect it in rain or snow, the metal surface will not be corroded due to weather problems.

3. In the process of rust prevention, it is very important not to ignore the movable part of the crane. For these parts, you can use No.-10 or No.-20 diesel oil to paint. This will not only remove the substances that are easy to corrode the equipment, but also form an oil film on the metal surface to resist low temperatures.

4. In addition to cleaning and lubricating with diesel oil, a layer of lubricating oil should be applied. It is best to choose calcium-based or lithium-based grease, because they have a good effect on maintaining the performance of all aspects of the machine, and when the equipment is used again, these greases will be easier to remove.

The crane will be painted to protect the equipment from corrosion when leaving the factory. When maintaining the single-beam crane, pay attention to whether the paint of the equipment is missing and repair it in time.
