Otis Elevator Company is the world's largest manufacturer of vertical transportation solutions, especially elevators (which Otis invented in most recently known form) and escalators. The company was founded in 1854 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 a local factory that injured the people using it [1].

From 1976 to 2020, Otis was a subsidiary of United Technologies Corporation. It was spun off on April 3, 2020. They have an elevator test tower in Bristol, CT which is about 28 floors. They also do tours of the test tower. They primarily test free-falls on their new, and old elevators. They also have some European Otis Gen2s there.

History

1853-1899

Otis 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 1853.

Elisha G. Otis

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 (US patent: 31128A[2]).

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 and was installed in the residence of Mrs. E. I. Shepard. It was the first recorded automatic (operatorless) elevator with push buttons.

1900-1999

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 1903. The first commercial installation was at the Beaver Building in New York City, NY.

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. Also in the same year, Otis installed their first elevator in Germany.

In 1915, Otis invented the self-leveling elevator, which they called the Micro-Drive. This elevator provides accurate stops at floor landings for the comfort of passengers. It was first used for the U.S. Army Bases during wartimes.

In 1921, Otis offered their first complete elevator maintenance service to Otis elevator owners in Springfield, IL.

In 1924, Otis introduced a high speed semi-automatic elevator, called SignalControl. This elevator could make accurate automatic stops from twice the speed possible with manual operation. It was first installed in the Standard Oil Building in New York City, NY. In the same year, Otis made their first modern style automatic door.

In 1925, Otis introduced Collective Control, the first ever selective-collective elevator system with a "memory", thus eliminating the need of elevator operators. This might have been the first Otis elevator model with fully automatic doors, but it is unconfirmed if this system always used automatic doors. Otis's Collective Control elevator was first installed in St. Luke's Hospital in Chicago, IL.

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 Elevatoring. Now, elevator operators were completely obsolete, and the elevator cars are operated automatically and electronically as a coordinated group. The first installation of this elevator was completed at the Atlantic Refining Company Building in Dallas, TX in 1950.

On July 7, 1976, after a hostile take over, Otis became a wholly owned subsidiary of United Technologies Corp.

In 1979, Otis introduced the Otis Elevonic 101, a fully microprocessor based elevator system for high-rise buildings.

Otis introduced the Otis Elevonic 401 elevator in 1981 which was equipped with synthesized automated speech, information display and security features.

In 1983, Otis introduced a computerized dispatching service called OTISLINE. This service runs 24 hours a day and designed for Otis elevator mechanics. Initially, the service was only available in North America but it was later introduced in France in 1984 and China in 2000.

In 1988, Otis introduced Remote Elevator Monitoring or REM, which is a diagnostic system for checking and monitoring elevator performance from distant locations. In 1995, the system was expanded to 8 of 18 countries by introducing REM III.

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".

2000-current

In 2000, Otis introduced its machine-roomless elevator product, Gen2, which replaces conventional steel cables with flat polyurethane coated steel belts. It also features a smaller, energy-efficient gearless machine. The Gen2 elevator was introduced to the North American and Japanese market in 2003.

Otis introduced its destination dispatch system called "Compass" in 2005, which is similar to Schindler Miconic 10 elevators. In 2013, Otis introduced its new generation "CompassPlus" destination dispatch.

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.[3]

On November 26, 2018, United Technologies, the owner of Otis, announced the completion of acquisition of Rockwell Collins, additionally they announced a split-off of its non-aerospace assets[4]. One of these is a UTC's elevator and escalator business, which is actually an Otis. In June 2019, United Technologies announced the intention to merge with defense contractor Raytheon to form Raytheon Technologies Corporation. Like it was announced after the merger with Rockwell Collins, this company will not include any non-aerospace-and-defense businesses as they would be splitted off from UTC earlier. Separation of these businesses was approved by United Technologies board of directors on March 11, 2020[5]. Otis Elevator Company, along with Carrier, was successfully spun off on April 3, 2020. Quickly after, its former parent, United Technologies, completed its merger with Raytheon, becoming Raytheon Technologies Corporation.

Since Otis's spun-off from United Technologies, Otis Elevator Company is a trading company behind Otis, and publicly-traded owner is named Otis Worldwide Corporation[6]. It is traded on the New York Stock Exchange with ticker OTIS.

Accidents and incident

  • On 13 May 2003, an upward escalator at City Hall MRT station, Singapore suddenly reversed, flinging some 20 people on it backwards, including a woman who was pregnant.
  • On July 24, 2009, a group of 8 people were trapped for 8 hours in an Otis elevator in Toronto. A repair man who tried to fix the elevator fell more then 20 floors to his death.
  • On December 14, 2010, an Otis escalator installed in the International Trade station of Shenzhen Metro Line 1 retrograded without notice, causing 25 passenger injures.
  • On July 5, 2011, an Otis 513MPE escalator installed at Beijing Subway Line 4 Zoo Station escalator changed direction without notice, causing 30 people to fall. One boy was killed and 27 people injured, prompting China to halt the use of the escalator model.
  • On March 25, 2017, a long Otis escalator which ran from the 4th to 8th floor of Langham Place in Hong Kong, China, malfunctioned which caused 18 people injured. The escalator suddenly stopped, reversed and then sped up. The cause of the accident was suspected to have been caused by a faulty drive chain and the emergency brake system failed to work[17].
  • In February 2007, the European Union regulators fined Otis Elevator 225 million Euros for being part of a price-fixing cartel. Other manufacturers such as ThyssenKrupp, Schindler, Kone and Mitsubishi Elevator Europe were also fined similar amounts in the same cartel.
  • On December 19, 2015, an older Sovietic elevator modernized in 2001 by Otis MCS-300 at Ostrovityanova 49 in Moscow, Russia, young mother rolled her stroller into the elevator and the elevator suddenly broke the rope and as a result of the arrival of one floor stroller ripped and 10 month old girl died.

Trivia

  • Otis elevators in Japan which were installed prior to 2005 are branded as National OTIS. This is because Otis products in Japan had routes directly sold by the company and routes to sell via Matsushita Electric Industrial Co., Ltd. (now Panasonic). The "National OTIS" brand was abolished as a new cooperation system was established between Matsushita Electric and Otis in July 2005.
  • Otis has also dabbled in horizontal automated people-mover "shuttle" systems, such as the Otis Hovair.
  • In some parts of the Canary Islands in Spain, Otis is known as "Zardoya OTIS" (Gran Canaria, Lanzarote, and La Gomera) and "Schneider OTIS" (Tenerife).
  • Some Otis elevators in the United Kingdom has the Drucegrove Digitalker voice announcer.
