1. Escalator chains are mostly used in shopping malls, subways, stations, airports, etc. Since escalators have long working hours and high safety requirements, the step chain must meet the specified minimum tensile load.

2. The escalator chain is a low-speed heavy-duty transmission. The escalator chain has an accurate transmission ratio, compact structure, high transmission efficiency, high requirements for the working environment, and different requirements for different occasions.

3. The escalator chain has small force per section, high strength and long life. The chain has good buffering, strong shock absorption performance, high speed and low noise during transmission.
