Escalator Industry
Escalator chain is used in escalator and moving sidewalk system to transfer power and transport passengers. Escalator chains are widely used in subways, high-speed rail, airports, high-end shopping malls, supermarkets and other places along with escalators and other facilities, including various drive chains, escalator step chains and automatic sidewalk pedal chains.
Features:
Escalator chain has the characteristics of chain length synchronization accuracy, step distance accuracy and high step distance synchronization accuracy, which meet the requirements of smooth operation. Various special structural designs and unique processing and manufacturing technologies are adopted to meet the requirements of safety, reliability, environmental resistance and long service life.
