Escalator chains generally include: escalator step chains and moving walkway chains. These chains are critical and important components in escalator equipment. Since escalators are public equipment that carry passengers, they must be safe, reliable, and provide a certain level of comfort, meaning the escalator must operate smoothly with low noise. According to the special requirements of escalator working conditions, through reasonable material selection and optimized heat treatment processes, Global Escalator Chains have developed products with high strength, high fatigue resistance, high wear resistance, high precision, and long service life. Currently, multiple high-gradient, high-strength, and other high-end Global Escalator Chains have been developed.
