Thirteen people were injured yesterday when an upward-moving escalator at the Jing’an Temple Metro Station suddenly changed directions due to a malfunction.
According to microblog posts by the Shanghai Shentong Metro Group, the ascending escalator’s chain snapped around 8:20 a.m., causing it to suddenly descend. Several passengers fell and attempted to climb up the escalator, hurting themselves in the process, according to the Global Times.
Commuters on the escalator were taken to the hospital, and only one suffered serious injuries. Five of the injured had left the hospital by Wednesday afternoon.
The escalator was manufactured by Otis Elevator Co Ltd in Guangdong province, and the company had reportedly inspected this particular escalator for maintenance on July 26.
Otis, founded in New York in the United States, is the world’s largest manufacturer of elevators and statistically is the world’s most popular transportation company.
Otis escalators have had a number of similar malfunctions in the past. In December 2007, an Otis escalator suddenly changed directions at Century Avenue Station on Line 4, and in July of 2011, one escalator of the same manufacturer abruptly stopped at the Caoyang Road Station on Line 3.
On July 5, 2011 in Beijing, a 13-year-old boy was killed and 30 more injured when a crowded upward-moving escalator suddenly reversed directions at the Beijing Zoo Station on Line 4, according to China Daily.
