What should I do if the hand chain hoist cannot be pulled down?

First, the reason why the hand chain hoist cannot be pulled when it falls

The hand chain hoist is a commonly used lifting tool, but sometimes it cannot be pulled when it drops. The reasons for this situation may be the following aspects:

1. The load-bearing capacity is too high: If the goods carried by the hand chain hoist are too heavy, it will cause the descent to be slow or unable to be pulled down.

2. Oil seal aging: The aging of the oil seal of the hand chain hoist will cause oil leakage, which will cause the hand chain hoist to drop and become unable to pull.

3. Insufficient oil: The descending speed of the hand chain hoist is directly affected by the oil, so insufficient oil will also cause slow descent or failure to pull down.

Second. Solution

1. Reduce the load-bearing weight: If the object carried by the chain hoist is too heavy, you can consider reducing the weight of the object and use other tools for lifting.

2. Replace the oil seal: If the oil seal of the hand chain hoist ages and cannot be pulled down, the oil seal needs to be replaced. It is recommended to follow the instructions when replacing the oil seal to avoid problems.

3. Add oil: If there is insufficient oil in the hand chain hoist, resulting in slow descent or failure to pull down, sufficient oil needs to be added. When filling oil, you need to choose the correct type of oil and be careful not to add too much oil.

Third, precautions and safety tips

1. The hand chain hoist must be operated in accordance with the instructions when using it, and parts must not be modified or replaced at will.

2. The load-bearing weight of the hand chain hoist shall not exceed the specified range.

3. Pay attention to safety when using the hand chain hoist to avoid accidents caused by improper operation.

4. The chain hoist should be properly kept after stopping use to avoid damage or loss.

In short, the hand chain hoist cannot be pulled down due to reasons such as excessive load-bearing, aging oil seal, or insufficient oil. After taking the corresponding solutions, it is recommended to operate according to the precautions and safety tips to avoid safety accidents.
