When encountering the problem of chain jamming in hand cranked hoists, there are several steps you can take to solve the issue. Here are some effective methods:

Check the Chain and Sprocket Alignment:

Ensure that the chain is properly aligned with the sprocket. Misalignment can cause the chain to bind or jam.

Adjust the tension of the chain if necessary. Overly tight or loose chains can both contribute to jamming.

Inspect the Chain for Damage:

Look for signs of wear, rust, or other damage on the chain.

Replace damaged or worn chains as soon as possible to prevent further issues.

Clean and Lubricate the Chain and Sprocket:

Regularly clean the chain and sprocket to remove dirt, grease, and other debris that can cause jamming.

Apply a suitable lubricant to the chain and sprocket to reduce friction and wear.

Check the Chain Tensioner:

Ensure that the chain tensioner is functioning properly. A malfunctioning tensioner can cause the chain to become too loose or too tight.

Adjust or replace the tensioner as needed.

Inspect the Drive Mechanism:

Check the gears, bearings, and other components of the drive mechanism for wear or damage.

Replace worn or damaged parts to ensure smooth operation.

Avoid Overloading the Hoist:

Ensure that you do not exceed the recommended lifting capacity of the hoist.

Overloading can strain the chain and drive mechanism, leading to jamming or other issues.

Regular Maintenance:

Perform regular maintenance on the hoist to keep it in good working condition.

This may include inspecting the chain, sprocket, and drive mechanism, as well as tightening any loose bolts or screws.
