Escalator

Description

An escalator is a moving staircase that carries people between floors of a building or structure. It consists of a motor-driven chain of individually linked steps on a track that cycles on a pair of tracks that keep them horizontal.

Escalators are often used around the world in places where lifts would be impractical, or they can be used in conjunction with them. Principal areas of usage include department stores, shopping malls, airports, transit systems (railway/railroad stations), convention centres, hotels, arenas, stadiums, and public buildings.
Escalators have the capacity to move large numbers of people. They can be placed in the same physical space as a staircase. They have no waiting interval (except during very heavy traffic). They can be used to guide people toward main exits or special exhibits. They may be weatherproofed for outdoor use.

Advantages of Escalator

• It is more efficient as people don’t have to wait as in the case of an elevator.
• Its speed can be adjusted as per crowd management and can be turned off when not in use.
• It has more loading capacity and allows a large number of people to move from one place to another at the same time.
