Causes and repair methods of hand chain hoist slipping

1. Reasons for slippage of hand chain hoist

1. Gear wear: Gear wear is one of the main reasons for hand chain hoist slippage. If the gear tooth surface is severely worn, the friction will be reduced, so the hand chain hoist will not be able to work smoothly while bearing the load.

2. Poor lubrication: The inside of the hand chain hoist needs lubricating oil. If the lubricating oil is insufficient or of poor quality, it will also cause the hand chain hoist to slip.

3. Excessive load: The hand chain hoist can withstand a certain load. If the load is too large, it will easily cause the hand chain hoist to slip.

2. Repair method of hand chain hoist slipping

1. Check the gears and lubricating oil: First, check whether the gears are worn. If the wear is serious, the gears or internal parts need to be replaced. At the same time, you should also pay attention to whether the lubricating oil inside the hand chain hoist is sufficient and whether the quality is up to standard.

2. Replace gears or internal parts: If the above methods cannot solve the problem of hand chain hoist slipping, then you need to replace gears or internal parts. This step requires disassembling the hand chain hoist, finding the problematic parts and replacing them.

3. Add anti-skid materials: If the chain hoist is used frequently, you can consider adding some anti-skid materials inside, such as graphite or molybdenum.

In short, the reasons for hand chain hoist slippage are usually related to gear wear, poor lubrication, excessive load and other issues. To solve the problem of hand chain hoist slipping, you can first check the gears and lubricating oil. If these methods cannot solve the problem, you need to replace the gears or internal parts. If you are a beginner, it is recommended to ask professional technicians to handle it.
