Sigma Elevator Company is a South Korean elevator company. A subsidiary of Otis Elevator Korea (OEK) in South Korea, it serves as a brand of Otis Elevator Korea for overseas/export markets and was established in 2000 to replace the LG-OTIS brand overseas.
History[]
Sigma was established in 2000, a year after Otis merged with LG Industrial Systems's elevator division and became LG-OTIS. It was established as a brand of Otis Korea for overseas markets.
In 2014, Sigma had a partnership with Express Elevator Co., Ltd., an elevator company based in Suzhou, China as well as a subsidiary of Otis[1]. In 2016, Express/Sigma opened their headquarters in Suzhou, China[2].
In 2016, the Sigma factory in Dalian was closed. In October 31, 2017, Express/Sigma consolidated with Otis Electric. Express Elevator Co., Ltd. became defunct in China, while Sigma continues to serve markets outside China Mainland. Maintenance work of the two companies in China was taken over by Otis.[3]
Locations[]
As of now, Sigma has operations in over 60 countries which are all represented by local distributors and sole agents. It also has subsidiaries located in Singapore (currently subsidiary of Otis Singapore Co (S) Pte Ltd.[4]), Malaysia, Thailand and Hong Kong (China, currently subsidiary of Otis Elevator Company (HK) Ltd.). Nowadays, all of the subsidiaries were transferred to corresponding Otis subsidiaries respectively in 2015.
The headquarters is located on the eight floor of Two IFC in Seoul, South Korea. Its factories are in China, one located in Hangzhou (Otis Electric) and another one located in the Tianjin Economic-Technological Development Area (TEDA) in Tianjin (Otis Tianjin factory). It also has another factory in Dalian (operated by Dalian Sigma Elevator Company) which was opened in 1997 to meet the demands on the Chinese elevator market. It was closed in 2016.
Until 2013, production was mainly done in their Changwon factory in South Korea, which had been operating when GoldStar was still in business. In 2013, the factory was closed after it was sold to LG Electronics, and production was moved to China. This was also the same case for Otis Elevator Korea, where elevators installed in South Korea were manufactured in China. In 2017, Otis Korea announced that it would build a new research & development center and a manufacturing facility in Songdo International City in Incheon, South Korea, which construction started in 2018 and was completed in 2019[5][6][7][8]. With local production for Otis Korea has resumed in this new facility, it is likely that Sigma would resume its local production there.
In the United States, Sigma elevators were distributed by CemcoLift, an elevator company based in Hatfield, PA that was part of Otis. However, CemcoLift shuts down in 2012[9] and distribution of Sigma elevators has since been discontinued. CemcoLift had only installed very few Sigma elevators in the U.S.

Incidents[]
- A Sigma elevator (Lift 5) in Blok M Square, Jakarta, Indonesia fell down from the 7th floor in the afternoon of March 17, 2017. The accident was caused by overloading; the elevator, which has a capacity of 24 persons or 1600 kilograms, was filled with 25 people (although some sources said that 35 people were entering the elevator). Witnesses said the elevator stopped on the 3rd and the 1st floor (because of safety brake got triggered) during freefall before hitting the bottom floor, injuring 25 people inside[14][15]
- Another Sigma elevator fell down in Pattaya Center Hotel in Pattaya, Thailand on March 7, 2017, causing nine district officials injured.[16].
- Between 2015 and 2017, several new Sigma elevators in various Housing & Development Board (HDB) estates in Singapore were plagued by numerous breakdowns and problems[17]. This resulted the company being banned by HDB from tendering new projects since late 2015.
Trivia[]
- In Taiwan, Sigma elevators are installed by Tatung Otis Elevator, and elevators in there are often branded as Tatung Otis.
- Since Sigma is a subsidiary of Otis Korea, the name "Otis Elevator Korea" (or OEK) is often found in certain parts or components that are usually not visible to the public. The name is also printed in the elevator protective covering sheets, which are usually found in brand new elevators that have just been installed.
- A few China made Sigma models, such as the Iris NV and Solon NV, were also sold in South Korea but they were branded as Otis. This is because Otis Korea had closed its local factory and moved its production to China, so most of the elevators installed before 2019 came from China.
