An elevator (lift in British English) is a type of vertical transport equipment that efficiently moves people or goods between floors of a building, or other structure. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.
