Causes and solutions for chain block jams

The use of hand chain hoists to lift heavy objects in cargo stations is simple and labor-saving, but the chain hoists have been stuck in the long-term use of the chain hoists, which directly affects the normal use of the chain hoists and reduces work efficiency. In order to avoid the discovery of the chain hoist chain jam, we must first know the reasons for the chain hoist chain jam, and then solve them.

What are the reasons for the chain hoist chain jam?

1. The chain hoist has quality problems, and the use of tools that do not meet the quality standards is prone to failure.

2. The chain hoist was not fully inspected before use. Chain twisting, knotting, rusting, deformation, etc. will cause the chain hoist to jam.

3. The chain hoist has a serious collision during use, the outer shell is deformed and squeezed inward, the internal parts are damaged, and the chain does not run smoothly and jams.

4. The operator pulls the hand chain quickly, and the chain and the heavy object shake violently, which will directly affect the operation of the lifting chain and cause the chain to jam.
5. The lifting chain enters the guide wheel and is not taken out in time when used, causing the chain to get stuck.
6. The daily chain maintenance is not in place, and lubricating grease is not applied regularly, causing oxidation or rust of internal parts, and the chain cannot run smoothly. The performance is greatly affected, and the chain gets stuck during lifting.

The above points are common reasons for the chain jam of the hand chain hoist. How to deal with these problems in daily life?

The chain jam of the hand chain hoist will directly affect the normal use of the hand chain hoist, reduce work efficiency, operation safety, etc. How to solve the problem of chain jam?

Solution to the chain jam of the hand chain hoist:

1. Choose high-quality hand chain hoists. Chenghua hand chain hoists meet the quality standards, undergo strict quality inspections before leaving the factory, and are strong and wear-resistant.
2. Check the chain before use. If the chain is knotted or twisted, it should be straightened in time before lifting.
3. Apply lubricating grease and anti-rust grease to the chain to reduce chain wear and prevent chain jam during chain lifting.
4. The operator pulls the hand chain at a constant speed, and the heavy object is lifted smoothly.
5. The hand chain hoist is operated in a standardized manner, and violent shaking is avoided as much as possible to prevent damage to the components.
6. Clean and maintain the hand chain hoist on a daily basis, and repair or replace the chain in time when it is deformed, worn, rusted, etc.

The above is the solution to the chain jam of the hand chain hoist. It is very important to choose a high-quality hand chain hoist. Chenghua hand chain hoist chain is strong and wear-resistant, and the brake is flexible. During use, it rarely fails and has a super high cost performance.
