An elevator is a type of vertical transport equipment. Elevators are generally powered by electric motors that either drive traction cables or counter weight systems like a hoist or pump hydraulic fluid to raise a cylindrical piston like a jack.
An escalator is a moving staircase – a conveyer transport device for carrying people between floors of a building. The device consists of a motor -driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.
