Daily maintenance of the dedicated lifting chain for stage electric hoists
During daily maintenance of the lifting chain, it is necessary to ensure that the light is bright enough, and each chain link should be inspected, with a focus on checking for deformation, scratches, corrosion, and inner ring wear.
1、 A detailed inspection includes the following points:
1. Check if there are any abnormal sounds or vibrations during operation, and if the lubrication is in good condition.
2. Whether it is deformed, cracked, or corroded.
3. Check if the welding joint is loose or deformed.
2、 Chain length precision measurement method
When measuring, apply the specified measurement load on the chain to ensure that the chain is in a load-bearing state and the sprocket should ensure normal and tight meshing.
2. The chain before measurement should remain for 1 minute under a minimum ultimate tensile load of one-third applied.
3. Wrap the tested lifting chain around the two sprockets, and the upper and lower sides of the tested chain should be supported.
There are many errors in the installation process of the lifting chain, so we must pay attention to its installation. Next, I will talk to you about the impact of its installation.
1. If the chain is installed too tightly, it will have a certain impact on the lifting sprocket. Causing it to malfunction.
It feels very difficult to do homework, reduces work efficiency, and affects the progress of work.
2. If the installation is too tight. It can also increase the friction between the chain links, and sometimes even cause breakage, resulting in the equipment not working properly.
3. Of course, during installation, it should not be too loose. If it is too loose, heavy objects may fall off due to the large gap between the chain links during operation, leading to accidents.
The above is the impact of the installation of the lifting chain. You must be careful when installing it to prevent accidents from happening again.
