The most suitable tightness of the stage electric hoist lifting chain
We all know the importance of lifting chains in work, so do you know that adjusting the tightness of lifting chains is also crucial?
The tightness of the lifting chain should also be appropriate. If it is too tight, it will increase power consumption and cause bearing wear.
If the chain is too loose, it is easy to jump and fall off the chain. From this perspective, it is crucial to control the tightness of the chain,
The tightness of the chain should be such that when lifted or pressed down from the middle of the chain, the center distance between the two sprockets should be approximately 2% -3%.
In addition, the new lifting chain is too long or stretched after use, making it difficult to adjust. The chain links can be removed depending on the situation, but they must be even. The chain link should pass through the back of the chain, the locking piece should be inserted outside, and the opening of the locking piece should be facing in the opposite direction of rotation.
Reasons for cracking of the lifting chain of the stage electric hoist
The entire body of the lifting chain is made of high-strength manganese steel, which is more durable and wear-resistant during use. Improper operation can still cause it to break, and the reasons for cracking can be roughly divided into two types:
1. Strong cracking.
When subjected to strong impact, the chain is forcibly pulled apart. As long as we operate correctly during use and ensure that there are no dangerous objects in the working environment, it can be effectively avoided.
2. Fatigue cracking.
After long-term use, the appearance of the chain will undergo certain changes (deformation distortion wear cracking), which cannot be effectively avoided and can only delay its arrival time.
Kind reminder: When using lifting chains, we should try to avoid incorrect operations as much as possible to extend the service life of the chains.
