What to do if the lifting chain of the stage electric hoist is worn out and fails?
During the use of the stage electric hoist lifting chain, distortion and deformation often occur due to wear and tear, which can affect the safety of operation. This is a very common problem. How to operate it to reduce the degree of wear and tear? Actually, only two moves are needed:
First trick: Before use, apply a thin layer of lubricating oil evenly on its surface and let it stand for a period of time. After the grease is fully absorbed, use it again to reduce wear.
The second trick: Choose a suitable chain for work according to actual needs. If abnormal operation occurs during use, please stop the operation in a timely manner and inspect the chain, which can also achieve the goal of reducing wear and tear.
If the twisting degree of the lifting chain is relatively light, the lifting work can continue, but it is necessary to do a good job of inspection, regularly understand and record the degree of twisting, and if the danger cannot be ruled out, it should be immediately prohibited from use.
Correct operation of lifting chains
1. Connect the chain link correctly during the production process of the lifting chain.
Any connecting link should be processed to ensure that each link in the finished chain has the same condition.
2. Correct detection.
After heat treatment and other processes are completed, the finished chain should undergo relevant tests: there should be no torsion when placed in the tensile testing machine; When the chain is moved, it should rotate flexibly; After the verification power is removed, it should be carefully inspected and the non-conforming products should be adjusted.
Special attention should be paid to:
When using surface treatment processes such as acid washing or electroplating, there is a risk of brittleness in the chain, and a second tensile test should be conducted on the finished product.
If a connecting link is added during the production process of the lifting chain, the part of the chain affected by the connection treatment should undergo tensile testing and careful inspection again.
