Only five people were injured in the mishap during the morning rush hour in Ningbo, east China”s Zhejiang province.
The incident follows a number of tragic escalator deaths in China.
The latest drama unfolded when the escalator, which was going up one floor, suddenly switched direction – causing those on it to fall.
Passersby rushed to help as more people fell on top.
Ten injured passengers were taken to hospital with one woman badly injuring her knee.
The machine was turned off after the incident while an investigation is carried out.
The latest incident is one of many happening in China which does not have a good safety record.
That was the second fatal escalator tragedy in China since June – when a mum stepped through an unfastened metal panel at the top of an escalator and was “swallowed” by the mechanism inside.
