Escalators

What is a Escalator

An Escalator is a moving staircase that moves people between different floors of a building. They are powered by motors. The steps run on tracks. There is a handrail that moves with the escalator, that you hold onto when riding the escalator. There is also an emergency stop button, which stops the escalator, and a key switch, that restarts the escalator, in the up or down direction.
