Regarding the analysis of wire rope over winding and loosening issues by Beijing wire rope electric hoist manufacturers, we can explore the following aspects:

1、 Analysis of over winding problem of steel wire rope

1. Description of over winding phenomenon

Overwinding of steel wire rope usually refers to a series of problems caused by improper operation or equipment failure during the use of the steel wire rope, resulting in the rope being wound too many times on the pulley or drum. Over winding not only affects the normal operation of the electric hoist, but may also accelerate the wear and breakage of the steel wire rope.

2. Analysis of reasons for over winding

Improper operation: The operator did not follow the specifications for the operation, such as excessively lifting or lowering heavy objects, resulting in the steel wire rope winding too much on the drum.

Equipment malfunction: The limit device of the electric hoist fails to stop the rotation of the drum in a timely manner, resulting in over winding of the steel wire rope.

Design flaw: Some electric hoists did not fully consider the issue of wire rope winding during design, resulting in over winding during actual use.

3. Solutions

Strengthen operational training: Regularly train operators to ensure they master the correct operating methods and avoid over winding problems caused by improper operation.

Regular inspection and maintenance: Regularly inspect and maintain the limit device of the electric hoist to ensure that it is in good condition and can detect and stop excessive rotation of the drum in a timely manner.

Optimization design: In the design stage of the electric hoist, fully consider the winding problem of the steel wire rope, adopt reasonable structure and parameter design, and reduce the occurrence of over winding phenomenon.

2、 Analysis of the loosening problem of steel wire rope

1. Description of loosening phenomenon

Loose steel wire rope refers to a series of problems caused by the unstable fixation of the steel wire rope on the pulley or drum due to various reasons during use. Loosening not only affects the lifting capacity of electric hoists, but may also pose safety hazards.

2. Analysis of loosening reasons

Long usage time: After prolonged use, the fixed end of the steel wire rope may become loose due to wear and fatigue.

External impact: During use, electric hoists may be impacted by external forces, causing damage or loosening to the fixed end of the steel wire rope.

Improper installation: The steel wire rope may not be fixed according to the specifications during installation, or the fixing method may be unreasonable, which may also lead to loosening problems.

3. Solutions

Regular inspection and maintenance: Regularly inspect and maintain the fixed end of the steel wire rope to ensure that it is in a secure state. When looseness is found, it should be promptly tightened.

Use high-quality steel wire rope: Choose reliable and high-performance steel wire rope products to reduce looseness caused by material issues.

Strengthen protective measures: During the use of electric hoists, appropriate protective measures should be taken, such as setting up protective covers, to reduce the impact of external forces on the steel wire rope.
