Passenger Escalator

A passenger lift has a completely enclosed lift car that travels vertically within a specially prepared lift shaft. Passengers are transported between floors at reasonably quick speeds and the control systems are often designed to give the most economical distribution of passengers throughout the building.Elevators, or lifts, carry passengers and freight up and down; escalators are moving staircases from one story of a building to the next; and moving sidewalks carry people horizontally or at a slight incline.
