Why does the stage hand chain hoist lifting chain twist?
The twisting of the lifting chain is one of the common phenomena that occur during the use of stage chain hoists. The twisting of the chain is very troublesome and even poses a danger to our work. Therefore, for the sake of our life safety, we must prevent similar incidents from happening.
So what should we do when twisting occurs?
1： During the rising process, twisting and bending can easily cause chain jamming problems, so we should smooth it out before use;
2： The sprocket or guide wheel of the stage chain hoist is damaged, both of which can cause the chain to twist during the lifting process. Therefore, we should pay attention to the maintenance of the parts.
3： When not using this product, it should be stored in the correct environment to extend the life of the chain, especially for chains that have not been used for a long time, regular inspections are still necessary.
Note: During the installation of the lifting chain of the stage chain hoist, it should not be hung on the lifting sprocket casually. It should be installed and fixed according to the installation regulations to avoid accidents during use.
The stage electric hoist lifting chain can be adjusted according to the lifting height of the lifting object, and the length of the chain can be adjusted. It is an essential and important component of the lifting device for cranes. However, it must be prohibited to use in any of the following situations:
1. Distortion, severe rust, and scaling cannot be eliminated, and the dangerous section wear of components and accessories is reduced by 10% of the original size. It is prohibited to use;
When the elongation of a single link exceeds 3% of the nominal pitch, and the elongation of a double link exceeds 5% of the nominal pitch, it is prohibited to use it;
3. When inspecting chain link welding cracks or other harmful defects with the naked eye or other equipment, it is prohibited to use it;
4. After being damaged by the heat source, it cannot continue to be used;
5. After excessive pitting or corrosion (acid, alkali), it cannot be used again.
