Which Components Are Typically Upgraded in Escalator Modernization?
As the years of operation increase, the performance, stability, and safety of escalators gradually decline. To comply with the latest safety standards, improve operating efficiency, and extend service life, escalator modernization has become a preferred solution for many shopping malls, metro stations, and office buildings. So, which components are usually the focus during an escalator upgrade?
1. Main Control System (Escalator Control Cabinet)
Older escalator control systems often respond slowly and have a high failure rate. During modernization, they can be replaced with an intelligent VVVF escalator control system to achieve energy-saving operation, smooth start/stop, and precise control. For example, the A-FLY intelligent escalator control system is compatible with multiple brands and easy to upgrade.
2. Drive System (Escalator Traction Machine)
The drive unit is the “heart” of the escalator. In modernization projects, motors, brakes, or couplings are often replaced to ensure stable drive force and reduce noise. When used together with an energy-saving inverter (VFD), energy consumption can be significantly reduced.
3. Escalator Handrail Belt
After long-term use, handrails can become loose, slippery, or worn. Replacing them with A-FLY’s upgraded handrail belts not only improves appearance but also enhances stability and passenger comfort during operation.
4. Step Chains and Step Components
Step chains operate under continuous load, and chain wheels may wear out over time. Step chain pins may also lose precision or become rusty. Therefore, replacing the step chains and steps is one of the key parts of modernization and can significantly improve safety performance.
5. Safety Protection Devices
Older escalators usually lack modern safety functions such as anti-reversal protection, step lighting, and entry warning lights. Adding these safety devices helps prevent accidents and improves overall safety.
6. Guide Wheel System
Handrail drive wheels, friction wheels, and other guide wheels need to be replaced regularly to prevent damage to the handrail belt and ensure smoother operation.
Summary
Escalator modernization is not just a simple parts replacement—it is a systematic upgrade process. With proper evaluation of escalator condition and a combined solution of energy-saving and safety upgrades, working with a professional escalator parts supplier like A-FLY can significantly extend equipment lifespan, enhance safety, and improve passenger experience while reducing maintenance costs.
