Elevator Compensation Chain Introduction and Usage Precautions

December 06, 2024
The Elevator Compensation Chain is a component used to connect the elevator car and counterweight, balancing the weight of the traction rope and the traveling cable, playing a balancing role in the operation of the elevator.

When the elevator is in operation, the length of the steel wire rope on the car side and the counterweight side is constantly changing, which leads to a change in the weight of the steel wire rope on both sides of the traction sheave. When the elevator lifting height is not significant, this weight change has a minor impact on the performance. However, when the lifting height exceeds a certain level, it can severely affect the stability of the elevator's operation, endangering passenger safety. At this point, it is necessary to install an Elevator Balance Compensation Chain with a certain weight to balance the weight difference caused by height changes.

There are several common types of compensation chains available on the market:

  • Wrapped Fiber Compensation Chain: Can be used up to a speed of 4m/s, suitable for various cold and harsh environments, it is currently a high-performance compensation chain, but the price is relatively high.
  • Fully Plastic Compensation Chain: With a cable-like PVC structure, it can be used up to a speed of 3m/s, and the elevator operation can achieve a smooth and quiet effect, which is favored by many large elevator companies.
  • Plastic-Coated Compensation Chain: With a flat PVC structure, it can be used up to a speed of 2m/s, its performance is slightly inferior to the fully plastic compensation chain but superior to the rope-through compensation chain, and the price is relatively cheaper.
  • Rope-Through Compensation Chain: The structure is a hemp rope threaded through an iron chain, usually only suitable for speeds below 1m/s. The elevator operation is noisy, and there is a noticeable shaking sensation inside the car. This is the most primitive type of compensation chain, and most elevator companies have now switched to using the above three types of compensation chains instead.

When using elevator compensation chains, the following points should be noted:

  • Choose the appropriate type of compensation chain: Based on the elevator's operating speed, lifting height, usage environment, and other factors, select the appropriate type of compensation chain to ensure it can function properly and meet the smoothness and safety requirements of the elevator operation.
  • Ensure the quality of the compensation chain: A high-quality compensation chain can make the elevator operation safe and smooth, achieving a quiet and comfortable effect. Poor-quality compensation chains may have issues such as severe shaking during operation, causing car swaying and loud noise, short service life, poor flexibility, easy cracking of the outer layer, poor strength, and instability leading to chain breakage accidents. When purchasing compensation chains, choose products that meet standards and are reliable in quality.
  • Correctly install the compensation chain: The installation of the compensation chain is usually carried out during the elevator commissioning. One end is hung under the car, and the other end is attached to the lower part of the counterweight. This compensation method is called symmetrical compensation, which has the advantage of not requiring additional counterweight or increasing the space in the hoistway. When installing, attention should be paid to the appropriate length of the compensation chain, neither too long nor too short, and ensure that its ends are securely fixed.
  • Regular inspection and maintenance: The compensation chain may experience wear, deformation, and chain breakage during long-term use, so regular inspection is necessary. The inspection includes checking for any damage, twisting, or breaks in the appearance of the compensation chain; whether the connection parts are firm; and whether there are any abnormal noises or vibrations during operation. If any issues are found, timely maintenance or replacement should be carried out.
  • Pay attention to environmental factors: Avoid the compensation chain coming into contact with water, oil, and other substances to prevent accelerated corrosion and aging. At the same time, ensure the cleanliness of the elevator hoistway to prevent debris from entangling or scraping the compensation chain.
  • Follow relevant standards and regulations: Strictly adhere to national and industry standards and regulations, as well as the requirements of the elevator manufacturer, in the selection, installation, and maintenance of the compensation chain.
  • Secondary protection for the compensation chain: Set up secondary protection devices for the compensation chain according to the requirements of the elevator manufacturer to prevent more serious accidents in case of abnormal situations (such as detachment).

In summary, correctly selecting, installing, and maintaining the elevator compensation chain is crucial for ensuring the safety and smooth operation of the elevator. By paying attention to the above usage precautions, the operation quality of the elevator can be improved, the service life of the compensation chain can be extended, and the safety and comfort of passengers can be ensured. At the same time, it is recommended that professional elevator maintenance personnel carry out regular inspections and maintenance work.
