When the zipper of the chain hoist suddenly stops moving, no matter how hard you try, you must remain calm! At this moment, pulling forcefully is like trying to break open a rusty iron lock with brute force, which not only fails but may also cause damage to the chain, leading to a catastrophic fracture.

In this situation, the first thing to do is to immediately stop the homework and conduct a comprehensive inspection of the chain. The first step is to check if the suspended object is overloaded, just like a small car trying to pull away a few tons of goods, the chain naturally cannot handle it. Next, carefully check whether the chain is twisted or tangled, which hinders the normal operation of the chain; Meanwhile, rust can also cause the chain to move slowly, increasing the resistance to pulling. If you find these problems, you can patiently straighten the chain and try pulling it gently a few more times, perhaps it can be restored to normal.

The daily maintenance of the chain of a chain hoist is very important. Regularly applying lubricant to the chain is like injecting a "vitality factor" into machine parts, which can effectively reduce wear and prolong service life. Next time you use a chain hoist, remember to be careful and keep the chain in its best condition to ensure safe operation.
