The elevator (or lift in the Commonwealth excluding Canada) is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel or other structures. 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.
In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles/forks of hay elevators.
Languages other than English may have loanwords based on either elevator (e.g., Korean and Japanese) or lift (e.g., Russian and Cantonese).
Because of wheelchair access laws, elevators are often a legal requirement in new multistory buildings, especially where wheelchair ramps would be impractical.

Famous quotes containing the word elevator:
“The indifferent clerk he knowing what was going to happen
The lobby zombies they knowing what
The whistling elevator man he knowing
The winking bellboy knowing
Everybody knowing! I’d be almost inclined not to do anything!”
—Gregory Corso (b. 1930)
“The cigar-box which the European calls a “lift” needs but to be compared with our elevators to be appreciated. The lift stops to reflect between floors. That is all right in a hearse, but not in elevators. The American elevator acts like the man’s patent purge—it works”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
