What is the simple definition of escalator?

1. Classification by Handrail Decoration

1. Fully Transparent Type: An escalator with a fully transparent glass balustrade. Based on the shape of the glass balustrade, it can be further divided into curved glass type and flat glass type.
2. Opaque Type: An escalator with a balustrade made of opaque metal or other materials. Since the handrail bracket is fixed on the upper part of the balustrade and the handrail moves in a continuous loop along the guide rail, the opaque type offers greater stability compared to the fully transparent type. It is mainly used in subways, stations, docks, and other high-traffic areas with significant height differences.
3. Semi-Transparent Type: An escalator with a semi-transparent balustrade, such as one made of semi-transparent glass or other materials.

In terms of handrail decoration, fully transparent glass balustrades must meet a certain strength requirement, with a minimum thickness of 6mm. Due to their superior decorative effect, most escalators use flat, fully transparent glass for the balustrade.

2. Classification by Step Drive Method

1. Chain Drive: An escalator where the steps are driven by a chain mechanism.
2. Rack Drive: An escalator where the steps are driven by a rack mechanism.

Due to its simple structure and lower manufacturing cost, the chain drive system is the most commonly used escalator drive method.

3. Classification by Lifting Height

1. Small Lifting Height Escalator: Lifting height 3–10m.
2. Medium Lifting Height Escalator: Lifting height 10–45m.
3. Large Lifting Height Escalator: Lifting height 45–65m.
