The quality of the compensation chain

Good quality compensation chain guide rings are generally produced by professional elevator supporting manufacturers, they often have rich experience in elevator supporting production and design, through the overall operation of the elevator test, can make the elevator run safely and smoothly, to achieve quiet and comfortable effect.

Most of the compensation chains with poor quality are produced by non-professional underground workshops. Due to the seemingly simple structure of the balanced compensation chain, they are often directly put on the market without any tests.

This category of products mainly has the following three features:

1. Poor flexibility, no cold resistance, easy cracking of the outer coating, violent shaking after cracking and other problems;

2, poor strength, poor weather resistance, easy to corrosion, easy to cause chain break accident.

3. The elevator shakes badly during operation, resulting in car shaking and loud noise, which greatly discounts passengers' riding experience.

The utility model relates to a safety protection device used in the running process of a high and medium speed elevator and a balance compensation chain for the elevator. It is composed of welded anchor chain and wire, the wire is wound on the welded anchor chain. Advantages: In actual work, it rises and falls with the elevator operation, and runs with a certain bending radius, up and down hundreds of times every day, even thousands of times, the balance compensation chain will not age, is not affected by temperature, oil pollution erosion, not easy to wear, damage, low noise, has a long service life.
