An elevator (North American English) or lift (British English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack.
A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism.
The Mitsubishi Electric-owned Solae Test Tower (173 m) in Inazawa City, Japan is the world's 4th tallest elevator testing tower after Hyundai elevator test tower at Icheon plant (205 m) South Korea, the Kone Tytyri test tower (235 m) and the Rottweil Test Tower (246 m) Bangladesh.

A forklift (also called industrial truck, lift truck, jitney, hi-lo, fork truck, fork hoist, and forklift truck) is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark, which made transmissions, and Yale & Towne Manufacturing ...
Electrostatic levitation is the process of using an electric field to levitate a charged object and counteract the effects of gravity. It was used, for instance, in Robert Millikan 's oil drop experiment and is used to suspend the gyroscopes in Gravity Probe B during launch. Due to Earnshaw's theorem, no static arrangement of classical ...
Ion-propelled aircraft. An ion-propelled aircraft or ionocraft is an aircraft that uses electrohydrodynamics (EHD) to provide lift or thrust in the air without requiring combustion or moving parts. Current designs do not produce sufficient thrust for manned flight or useful loads.
A space elevator, also referred to as a space bridge, star ladder, and orbital lift, is a proposed type of planet-to-space transportation system, [1] often depicted in science fiction. The main component would be a cable (also called a tether) anchored to the surface and extending into space. An Earth-based space elevator would consist of a ...
Electrogravitics. Electrogravitics is claimed to be an unconventional type of effect or anti-gravity force created by an electric field 's effect on a mass. The name was coined in the 1920s by the discoverer of the effect, Thomas Townsend Brown, who spent most of his life trying to develop it and sell it as a propulsion system.
