Overload protection for escalators is usually achieved by installing load cells (or load detection devices) before and after the step group to monitor the load on the steps. When the total load exceeds the preset limit, the sensor triggers the safety switch, cuts off the control circuit, and quickly stops the drive motor and brake to prevent damage to the steps or injury to passengers due to overload.

The escalator is equipped with an emergency stop button and electromagnetic brake, which can stop the escalator quickly in case of emergency or power failure; the step misalignment, step missing, collapse and transmission chain loosening or break detection device will automatically shut down the escalator; overspeed, anti-reverse, handrail synchronization/breakage monitoring, as well as machine room hatch and comb plate safety switches form multiple linkage protection to ensure long-term and safe operation.

When the escalator loses power, it relies on the electromagnetic brake (or mechanical slow stop system) to work with the frequency converter. The frequency converter first performs a controllable slow stop, and then the electromagnetic brake completely locks the steps and flywheel to ensure that passengers can get off the escalator safely without causing sudden stop shock. ​

Noise: The operating noise of high-quality models is ≤57 dB(A) (the measurement point is located at the reducer), and the overall control is within ≤65 dB(A);

Vibration: In terms of passenger experience, ISO 18738-1 stipulates that the longitudinal and transverse peak-to-peak vibration amplitude PP value is ≤15 mg, and the average A95 value is ≤12 mg;

Exceeding standard handling: Check for reasons such as insufficient lubrication, poor gear meshing, bearing damage or guide rail offset, clean, lubricate, adjust or replace parts in a timely manner, and retest until compliance is restored.

Anti-corrosion treatment: The frame and shell are hot-dip galvanized or sprayed with zinc aluminum alloy coating, and 316/304 stainless steel key components and marine-grade paint are used.

Waterproof seal: The drive motor, gearbox, bearings and electrical junction box all use IP66 or above seals and waterproof joints;

Drainage system: There are water collection tanks and drainage holes at the bottom of the steps and in the frame. The ground slope is ≥10° and covered with grilles to prevent water intrusion.

Enclosed switch: Outdoor safety switches and buttons are sealed, and the guide rails, sensors, etc. use dust covers to ensure stable operation in rain, snow and dusty environments.

Common alarms: overload alarm, step missing alarm, step collapse alarm, chain break alarm, overspeed/reverse alarm, handrail out of sync alarm, cabin cover open alarm, etc. Response process: The alarm immediately cuts off the drive and stops, and the control cabinet indicates the type of fault; before the maintenance personnel carry the key to reset, they must find out and eliminate the hidden dangers, and then confirm the reset through the control key or panel.
