What is an Escalator?
The escalator is a combination of a special structured chain conveyor and two special structured belt conveyors. It has a circular motion ladder path to move up or down between different levels of the building. Fixed electric drive to transport passengers at an angle. A continuous conveyor that carries people up and down.
- Escalator is running with loop
- 1. Classified by armrest decoration
- 1) Fully transparent: refers to escalators made of fully transparent glass, which can be further divided into curved glass type and flat glass type.
- 2) Opaque: refers to an escalator made of opaque metal or other materials. Since the armrest belt bracket is fixed on the upper part of the baseboard, and the armrest belt is circulated on the rail of the armrest bracket, the opaque type has better stability than the fully transparent type. It is mainly used for escalators with large heights, such as subways, stations, and terminals.
- 3) Translucent: refers to the handrail wallboard is translucent, such as the use of translucent glass and other materials.
- As far as handrail decoration is concerned, the fully transparent glass wainscot has a certain strength, and its thickness should not be less than 6mm. In addition, the fully transparent glass wainscot has good decorative effect. Escalators account for the vast majority.
- 2. Classified by step drive
- 1) Chain type: refers to an escalator whose components are driving chains.
- 2) Rack type: refers to an escalator whose component is a rack.
- Because the chain-driven structure is simple and the manufacturing cost is low, most escalators adopt a chain-driven structure.
- 3. Classified by lifting height
- 1) Escalator with small lifting height: lifting height 3 10m;
- 2) Escalator of medium lifting height: lifting height 10 45m;
- 3) Escalator with large lifting height: lifting height 45 65m [1]
- The main parameters of the escalator are:
- 1. Lifting height: generally within 10 meters, tens of meters in special cases.
- 2. Tilt angle: generally 30 °, 35 °.
- 3. Speed: generally 0.5 m / s, some ladders can reach 0.65 m / s, 0.75 m / s
- 4. Step width: 600mm, 800mm, 1000mm.
- 5. Theoretical conveying capacity: Calculated according to the speed of 0.5 m / s, the conveying capacity of different step widths is 4,500 persons / hour, 6,750 persons / hour, and 9,000 persons / hour.
- 6. Step pitch and traction chain pitch.
- It can be widely used in stations, docks, shopping malls, airports, subways and other places where people are concentrated. In 1900, a stepped escalator at the Paris International Fair was the prototype of a modern escalator. Since then, escalators have developed rapidly in various countries [1] .
