Steel wire rope is one of the important components of elevator safety devices, responsible for carrying the weight of the elevator body and the passengers or goods it carries. If the steel wire rope ages or breaks, it will pose a great threat to the safe operation of the elevator. Therefore, on the premise of safe use of elevators, regular maintenance and inspection of steel wire ropes is essential. This article will introduce the necessity, maintenance measures, and maintenance cycle of regular maintenance for steel wire ropes.

1、 The necessity of regular maintenance of steel wire ropes

1. Extend service life

The elevator steel wire rope is located in a high strength, high friction, and highly tense working environment, which is easily affected by wear, wire breakage, corrosion, and other issues, leading to increased wear and tear of the steel wire rope and reduced service life. Regular maintenance of steel wire ropes, keeping them clean and lubricated, will greatly reduce the risk of damage and extend their service life.

2. Ensure safe operation

Steel wire ropes carry weight in elevators, and if they age or break, it can pose a fatal risk to the elevator. Therefore, safety inspection of steel wire ropes is particularly important. Regularly maintain the steel wire rope, promptly detect and handle abnormal phenomena, and maintain the safe operation of the elevator.

3. Improve work efficiency

If the steel wire rope is not regularly maintained, it is easy to identify problems during use, leading to downtime for maintenance and an increase in repair costs. It can also lead to infrastructure downtime, thereby affecting the normal operation of the company's business. However, if there is a regular maintenance operation, it can predict elevator maintenance batches, reduce business interruption and time and money losses caused by elevator problems, and thus improve the company's work efficiency.

2、 Measures for Regular Maintenance of Steel Wire Ropes

When conducting regular maintenance of steel wire ropes, it is necessary to develop corresponding maintenance plans based on the actual situation, and the maintenance measures are as follows:

1. Keep clean

Steel wire ropes need to be kept clean and not affected by pollutants during use. However, if one is too lazy to carry out regular maintenance and cleaning, the elevator steel wire ropes will be exposed to water, dust, and heavy oil, which will oxidize and age, thereby accelerating the wear and tear of the steel wire ropes. Therefore, it is necessary to regularly clean the steel wire ropes during maintenance.

2. Smooth lubrication

The normal operation of steel wire ropes requires lubricants to ensure their elasticity, friction coefficient, and stability, thereby ensuring the smoothness and safety of elevator operation. During maintenance operations, it is necessary to lubricate the steel wire rope, especially for new ones, as lubrication can have a significant impact on it.

3. Verify tightness

During the use of steel wire ropes, their tightness, tension, and other information need to be verified at any time. During regular maintenance, tension, winding degree, and bending radius should be tested to determine if fatigue is allowed.

4. Check for wire breakage, wear, etc

Regular maintenance of the steel wire rope also requires checking its wear and tear to eliminate issues such as wear and breakage, and replacing the faulty steel wire rope.

3、 Regular maintenance cycle of steel wire rope

The regular maintenance cycle of steel wire ropes is mainly determined by factors such as their working environment, usage conditions, and hazard level. Usually, after 1000 hours of use, it is necessary to conduct preliminary testing and cleaning of the wire rope, and develop a wire rope replacement plan based on the usage amount. For steel wire ropes that have been in operation for more than 10 years, detailed cleaning and lubrication should be carried out at least once a year. Firstly, the wear and tear of the steel wire rope needs to be checked before maintenance.

4、 Summary

Steel wire ropes are an important component of the safe operation of elevators and must be regularly maintained to extend their service life, ensure safe operation of the elevator, and improve work efficiency. For steel wire ropes with different purposes and working environments, the maintenance cycle varies and needs to be determined based on specific circumstances. During the regular maintenance process, it is necessary to ensure the comprehensiveness, scientificity, and standardization of maintenance, which helps to ensure the safe operation of the elevator.
