Why is the surface of the lifting chain galvanized?
The production process of hot-dip galvanizing for lifting chains mainly includes: preparing the original color chain → pre-treatment before plating → hot-dip coating → post-plating treatment → finished product inspection, etc. Why is galvanizing necessary? Let's summarize the necessity of galvanizing below:
1. The galvanized layer mainly plays a certain isolation role, which can prevent the chain from coming into contact with air and being oxidized. Over time, the surface of the chain is prone to rusting, which affects its performance;
2. The galvanized layer can also prevent the chain from being subjected to friction, etc., and has wear resistance. This way, the chain can be subjected to friction in a timely manner during use without causing too much impact.
In humid air, a dense alkaline zinc carbonate film is formed on the surface of zinc to protect the internal structure.
Once the galvanized layer on the surface of the lifting chain is found to be damaged, it should be repaired promptly.
Before using the lifting chain, we need to inspect the chain to ensure safety during use.
Firstly, check the chain joints and ring chains for wear and cracks before use.
Secondly, during use, check if the chain is lifted vertically.
Then, when the lifting chain works on the sliding drum, its speed needs to be controlled.
Finally, during the use of the chain, avoid excessive vibration amplitude and pay attention to the use standards
