Otis Elevator Company is the world's largest manufacturer of vertical transportation system. The company was founded in Yonkers, New York, USA by Elisha Otis, who invented the safety mechanism of the elevator should the hoisting rope break. This was created due to an accident with a freight lift at an local factory that injured the people using it.
HistoryOtis was founded by Elisha Otis in New York, NY, USA, after he demonstrated the special safety elevator mechanism in the Crystal Palace Exhibition in New York City in 1854.
By the end of 1856, Otis had sold more than 40 elevators, all freight models. In 1857, the world's first passenger elevator was installed at E. V. Haughwuot & Company in New York, NY.
In 1861, Otis' elevator safety brake was patented.
After Elisha Otis died of diphtheria in 1861, the company was continued under his two sons Charles and Norton. Soon, the company was renamed to "Otis Brothers Co." with Charles as the company's president.In 1868, Otis developed a steam-powered passenger elevator and in 1870, the company introduce a water-pressured hydraulic elevator.
In 1875, Otis invented the elevator governor.
In the 1880s, Otis has established branch offices in London and Paris, and had installed elevators in the Eiffel Tower, London Underground, Glasgow Harbour Tunnel, etc.
In 1889, Otis installed the first 2 elevators of the first sucessful electric elevator model at the Demarest Building in New York, NY.
In 1892, Otis installed the first elevators with the Unit Multi-Voltage (formerly called Ward Leonard) principal, for smoother ride quality.
Otis invented the automatic elevator in 1894.
Otis developed the escalator technology in 1895 and was introduced it in the Paris Exposition in 1900, a step type escalator. After that, the same escalator was installed in a department store in Pittsburgh, PA (Possibly Kaufmann's).
In 1898, Otis greatly contributed to the high speed water hydraulic elevator.
Otis also made another type of escalator, called the cleat type escalator. This type was probably not popular, and was made for only maybe 20 years.
Otis invented the gearless traction elevator in 1902. The first commercial installation was at the Majestic Theater in Chicago, IL.
Otis invented the geared traction elevator in 1908. The cable wrapped around the motor multiple times.
Otis invented the modern style geared traction elevator in 1911. Now, the cable only goes over the motor. This technology is still used today.
In 1911, Otis installed their first elevator in Germany.
In 1915, Otis invented the self-leveling elevator, which they called the Micro-Drive.
In 1924, Otis introduced a high speed semi-automatic elevator, called Signal-Control.
Around 1924, Otis made their first modern style automatic door.
In 1925, Otis introduced Collective-Control, the first ever selective-collective elevator system. This might have been the first Otis elevator model with fully automatic doors, but it is unconfirmed if this system always used automatic doors.
In 1931, a double-deck elevator was introduced by Otis. The first one was installed in the Empire State Building in New York, NY.
Possibly in the 1930s, Otis started using steel steps for escalators.
In 1948, Otis introduced a high speed fully automatic elevator, called Autotronic. Now, elevator operators were completely obsolete.
On July 7, 1976, after a hostile take over, Otis became a wholly owned subsidiary of United Technologies Corp.
Otis purchased UK's oldest elevator company Express Lift Co. Ltd. of Northampton as well as Evans Lifts of Leichester in 1997. Later, both companies merged together to form "Express Evans".
Otis introduces it's destination dispatch system called "Otis Compass" which is similar to Schindler Miconic 10 elevators.
In 2013, Otis launched a new residential Gen2 Switch elevator that eliminates the need for three phase power, is solar-power capable, and uses battery technology to continue to run when the power goes out.
Otis has its headquarters in Farmington, Connecticut, USA and has major manufacturing facilities in America, Europe, and Asia. They have ten research centers globally, and six area headquarters located in:
- Farmington, Connecticut, USA
- Madrid, Spain
