The deformation, wear and tear of the steel wire rope of electric hoists, as well as the occurrence of scratches in the air, are common problems that may seriously affect the safety and efficiency of the use of electric hoists. The following is a detailed analysis of these issues, their causes, and protective measures:

1、 Deformation of steel wire rope

reason

No rope guide:

During the winding process of steel wire rope, if there is no guide from the rope guide, it is easy to cause rope disorder, resulting in the steel wire rope entering the gap at the end of the drum and being squeezed and deformed.

Solution: Install a rope guide to ensure that the steel wire rope is arranged in an orderly manner during the winding process, avoiding compression deformation.

Diagonal suspension:

During the operation, if a heavy object is lifted diagonally, it will cause uneven force on the steel wire rope, resulting in deformation.

Solution: Operate according to the operating procedures, prohibit diagonal pulling and lifting, and ensure that the steel wire rope is evenly stressed.

Protective measures

Regularly check the working status of the rope guide to ensure its normal operation.

Strengthen the training of operators and enhance their awareness of complying with operating procedures.

2、 Wear and tear of steel wire rope

reason

Diagonal suspension:

Cable pulling and hoisting not only cause deformation of the steel wire rope, but also increase friction between the steel wire rope and the drum shell, thereby accelerating wear.

Solution: Same as above, do not use diagonal braces or suspensions.

Improper selection:

The diameter of the steel wire rope is too large or too small, and it does not match the rope groove, which can lead to increased wear and tear.

Solution: Reasonably select the steel wire rope to ensure that its diameter matches the rope groove.

Usage environment:

Adverse usage environments, such as high temperature, humidity, corrosion, etc., can also accelerate the wear of steel wire ropes.

Solution: Improve the usage environment and take necessary protective measures, such as adding protective covers and using corrosion-resistant materials.

Protective measures

Regularly inspect the wear of steel wire ropes and replace severely worn ones in a timely manner.

Select steel wire ropes suitable for the usage environment and take necessary protective measures.

3、 Hanging flowers on steel wire rope in the air

reason

Improper entanglement:

When winding steel wire rope on the ground, if the rope is not loosened and straightened, it will be wrapped in the drum, which will cause the rope to become tangled in the air.

Solution: When winding the steel wire rope on the ground, ensure that the rope is wound in a relaxed state to avoid the occurrence of flower marks.

Protective measures

Strengthen the training of operators and improve their proficiency in wire rope winding operations.

Regularly check the winding status of the steel wire rope, promptly detect and correct any flower marks.
