In an escalator system, the step chain serves as one of the most critical components, directly driving the movement of the steps and ensuring smooth, safe, and stable operation.
As the main transmission link between the drive sprocket and the escalator steps, the step chain carries both the load of passengers and the mechanical stress of continuous operation, making its quality and reliability essential for the entire system’s performance and safety.
Structure and Function
The step chain consists of high-strength chain links, pins, bushings, and rollers, precisely manufactured to guarantee dimensional accuracy and smooth articulation.
During operation, the chain moves in synchronization with the drive system, guiding each step to run along the track at a constant speed, ensuring steady operation and passenger comfort.
To withstand continuous load and environmental stress, step chains are designed for high wear resistance, fatigue strength, and corrosion protection.
Technical Features
Our step chains are developed with a focus on durability, precision, and safety:
High-Strength Materials – made from heat-treated alloy steel for excellent load-bearing performance.
Precision Machining – ensures accurate pitch and smooth operation.
Enhanced Lubrication System – reduces wear and extends service life.
Corrosion-Resistant Surface Treatment – ideal for various indoor and outdoor environments.
Safety and Reliability in Every Detail
As the core driving component of the escalator, the step chain must deliver absolute precision and endurance. Even a minor deviation in length or wear can affect step alignment and safety.
Through advanced production techniques and rigorous quality control, our step chains ensure stable transmission, low noise, and extended service life, meeting the demanding requirements of modern escalator systems.
The safety of an escalator doesn’t only depend on its control system — it relies on every reliable component inside.
Among them, the step chain plays a crucial role, ensuring the escalator runs steadily, safely, and efficiently.
