Hand chain hoist malfunction and solutions?

1. Chain damage

The main manifestations of chain damage are breakage, severe wear, and deformation. If the damaged chain continues to be used, it will cause serious accidents and must be replaced in a timely manner.

2. Damaged hook

The main manifestations of hook damage are: fracture, severe wear and deformation. When the wear of the hook exceeds 10%, or when it breaks or deforms, it can lead to safety accidents. Therefore, it is necessary to replace the hook with a new one. If the above wear level is not reached, the full load standard can be reduced and continue to be used.

3. Chain twist

When the chain of the chain hoist is twisted, it will increase the operating force, causing the parts to get stuck or break. The cause should be promptly investigated, which may be due to chain deformation. If the issue cannot be resolved after adjustment, the chain should be replaced.

4. Card chain

The chain is stuck and difficult to operate, usually due to chain wear. If the diameter of the chain link is worn by 10%, the chain should be replaced in a timely manner.

5. Damaged transmission gear

The transmission gear is damaged, commonly including gear cracks, broken teeth, and tooth surface wear. When the wear of the tooth surface reaches 30% of the original tooth, it should be scrapped and replaced; Cracked or broken gears should also be replaced immediately.

6. Brake pad failure

If the brake pads do not meet the requirements of the braking torque, it will cause the lifting capacity to not reach the rated lifting capacity. At this time, the brake should be adjusted or replaced.
