Accidents

  • 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[8][9]
  • Another Sigma elevator fell down in Pattaya Center Hotel in Pattaya, Thailand on March 7, 2017, causing nine district officials injured.[10].
  • From 2015 to 2017, several new Sigma elevators in various Housing & Development Board (HDB) estates in Singapore were plagued by numerous breakdowns and problems[11]. Because of this, Sigma is currently banned by HDB from tendering new projects since late 2015.

Trivia
