To prevent fatigue loss of the electric hoist chain, the following measures can be taken:

1、 Choose the appropriate chain

Material selection:

Choose the appropriate chain material based on the working environment, load requirements, and frequency of use of the electric hoist. High strength, wear-resistant, and corrosion-resistant chain materials can better resist fatigue losses.

Specification matching:

Ensure that the specifications of the chain match the rated load of the electric hoist to avoid chain fatigue caused by overload use.

2、 Regular lubrication and maintenance

Lubrication chain:

Regularly lubricate the chain to reduce friction between the chain and sprocket, and lower the wear rate. Use specialized chain lubricant and ensure that the lubricant is compatible with the chain material.

Clean the chain:

Regularly clean the chain to remove dust, oil stains, and impurities from the surface, preventing these substances from accelerating the wear and fatigue of the chain.

3、 Reasonable use and maintenance

Avoid impact loads:

When operating an electric hoist, try to avoid sudden impact loads to reduce fatigue failure of the chain due to stress concentration.

Control operating speed:

Reasonably control the operating speed of the electric hoist to avoid excessive dynamic stress on the chain caused by being too fast or too slow.

Regular inspection and replacement:

Regularly inspect the wear and fatigue of the chain, especially key parts such as links, pins, and sleeves. If severe wear or cracks are found in the chain, it should be replaced in a timely manner to avoid breakage accidents.

4、 Improving the working environment

Reduce working temperature:

Try to keep the electric hoist and its chain running at a suitable working temperature to avoid chain relaxation, deformation, or accelerated aging caused by excessive temperature.

Reduce humidity and corrosion:

When used in damp or corrosive environments, necessary protective measures should be taken, such as installing rain covers, using corrosion-resistant materials, etc., to reduce the corrosion and fatigue loss of the chain.
