The Otis Elevator Company is an American company that develops, manufactures and markets elevators, escalators, moving walkways and related equipment. A pioneer in its field, Otis is the world's largest manufacturer of vertical transportation systems, principally focusing on elevators, moving walkways and escalators. The company pioneered the development of the "safety elevator", invented by Otis in 1852, which used a special mechanism to lock the elevator car in place should the hoisting ropes fail.
Otis has installed elevators in some of the world's most famous structures, including the Eiffel Tower, Empire State Building, the original World Trade Center, The Twilight Zone Tower of Terror, Petronas Twin Towers, Burj Khalifa, CN Tower, the Winchester Mystery House, the Hotel del Coronado, the Demarest Building (first electric elevator), the Singing Tower at Bok Tower Gardens and the Skylon Tower.
