To prevent fatigue loss of wire rope electric hoists, the following measures can be taken:

1、 Optimize design and selection

Increasing the diameter of the drum and pulley: If conditions permit, increasing the diameter of the drum and pulley can reduce the bending stress of the steel wire rope, thereby significantly improving the fatigue life of the steel wire rope.

Choose the appropriate steel wire rope: Try to choose a steel wire rope with a larger diameter and a surface that matches the diameter of the steel wire rope well. This type of steel wire rope has better toughness and elasticity, can resist external factors, and reduce fatigue damage.

2、 Standardized use and maintenance

Avoid reverse bending: When replacing a new rope, follow the principle of "upward, upward, downward" and try to avoid the steel wire rope from reversing. The experimental results show that the failure caused by reverse bending is about twice that of the same direction bending, so avoiding reverse bending is crucial for reducing fatigue damage.

Load control: When using an electric hoist, the load should be strictly controlled to avoid overloading or overloading operation. Overloading can cause the steel wire rope to bear excessive tension, thereby accelerating fatigue damage.

Regular inspection and replacement: Regularly inspect the wear of the steel wire rope, pulley and other components of the electric hoist, and replace them in a timely manner according to the degree of wear. If components with severe wear and tear are not replaced in a timely manner, it will exacerbate fatigue damage.

3、 Improving the working environment

Maintain a suitable ambient temperature: Avoid using electric hoists for long periods of time in high or low temperature environments, as temperature changes can affect the performance of steel wire ropes and accelerate fatigue damage.

Reduce the impact of humidity: Excessive humidity can cause corrosion on the surface of steel wire ropes, reducing their strength and toughness, thereby increasing the risk of fatigue damage. Therefore, it is advisable to avoid using electric hoists in humid environments or take moisture-proof measures.

4、 Strengthen lubrication and maintenance

Regular lubrication: Regularly lubricate the transmission system, pulleys, and other components of the electric hoist to reduce friction and wear, and lower the risk of fatigue damage.

Cleaning and maintenance: Regularly clean the body and steel wire ropes of the electric hoist, remove surface dirt and rust, and maintain its good working condition.
