The woman — identified in media reports as 30-year-old Xiang Liujuan — is shown reaching the top of the escalator when the section of landing platform she had stepped onto suddenly collapses, trapping her inside the still-moving machinery.
The footage shows that Xiang managed to push her son into the arms of shop attendants near the top of the escalator. The attendants tried to pull her to safety, but Xiang fell into the mechanism and was killed.
The state-run People’s Daily’s online edition and other media outlets said her body was recovered four hours later, after crews disassembled the escalator.
Although escalator deaths are extremely rare, China’s breakneck economic development and sometimes cavalier attitude toward safety, quality control and maintenance have led to frequent industrial accidents such as fires, building and bridge collapses, and ship sinkings or collisions.
