There is a very important part of the roller chain crane that is often overlooked, but that is the lifting chain. When the equipment is used for a long time, all components will tend to age or gradually fail, and the same will happen to the lifting chain. The more common phenomenon is the rust of the chain. In addition to time, what other reasons can cause similar problems to occur?
1. The lifting chain is corroded due to lack of anti-rust treatment
In the production process of the lifting chain, the operator did not strictly follow the production requirements for rust prevention treatment, and also did not use rust prevention packaging. Once it comes in contact with corrosive liquids, gases, etc., rust will occur. .
2. The rust of the lifting chain is caused by the quality of the anti-rust oil that does not meet the standard
Even if products such as anti-rust lubricating oil and clean kerosene have been applied to the lifting chain, if the quality of the product does not meet the process and technical requirements, it will be in vain and will also cause the rust of the lifting chain.
3. The rust of the lifting chain is related to the chain material
In order to reduce the production cost of lifting chains, some manufacturers choose unqualified materials, such as the high content of non-metallic impurities in steel, which reduces the corrosion resistance of the formed chain itself, leading to similar defects.
4. The rust of the lifting chain is related to the operating environment. When the lifting chain is working in a poor environment for a long time, it will be considered that the content of harmful substances is too high, or the space is too small for rust prevention, which will cause the chain Negative Effects.
