Based in Farmington, Connecticut, 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.
In 1852 Elisha Otis invented the safety elevator, which automatically comes to a halt if the hoisting rope breaks. After a demonstration at the 1854 New York World's Fair the elevator industry established credibility.
In 1925, the world's first fully automatic elevator, Collective Control, was introduced. Otis elevator installation at Winchester Mystery House. Otis was founded in Yonkers, New York in 1853 by Elisha Otis. It was acquired by United Technologies in 1976 and is a wholly owned subsidiary. Otis has more than 64,000 employees, with 2014 revenue of US$13.0 billion. The company headquarters are located in Farmington, Connecticut.
Otis has also dabbled in horizontal automated people-mover "shuttle" systems, such as the Otis Hovair. In 1996, Otis formed a joint venture called "Poma-Otis Transportation Systems" with the French company Pomagalski to promote these products. That partnership has since ended.
Otis Elevator Company purchased Evans Lifts in the UK when Evans Lifts Ltd went bankrupt in 1997 during its merge with Express Lift Company with the name ExpressEvans. It was the oldest and largest manufacturer of lift equipment in the UK, and was based in Leicester, England. Otis' Customer Care Centre is still based in the old Evans Lifts building in Leicester. The building has since been extended by Otis.
There are some installations of Evans Lifts in use today. Few lifts made by Otis are branded as Evans. Notably, an original Evans Lift is still in the Silver Arcade in Leicester. It formerly transported people to the upper floors. The upper floors are no longer occupied: the lift is no longer used.
