1. The chain hoist has been used for a long time, and the parts are severely worn. The parts of the whole chain hoist are supported by metal. It is inevitable that there will be wear and tear during operation. After a long period of use, abnormal noise or even mechanical damage will occur if worn to a certain degree.
2. The mismatch between the parts of the chain hoist will not only cause poor operation, but also make abnormal noises. The reason for the mismatch is mostly the replacement of unmatched parts or severe mechanical wear.
3. Inadequate maintenance or improper storage methods will cause oxidation and corrosion of the chain hoist, which will affect the operation of the bearing and cause abnormal noise.
Chain hoists should be inspected and maintained regularly during use, and problems should be discovered and repaired in time to avoid leaving hidden dangers and causing accidents.
