Scary elevator drama in tallest building caused by door glitch

A faulty car door controller is blamed for Tuesday's elevator accident that terrified 20 passengers in the 101-story Shanghai World Financial Center, quality supervisors said yesterday.

Initial investigation found the glitch caused the lower car of the double-deck elevator to close its door suddenly, trapping 20 passengers inside.

Since the upper car was working normally, the elevator went up and down between the first and 52nd floor four more times before coming to a stop on the first floor, said Wang Jun of the Pudong District Quality and Technical Supervision Bureau.

No one was injured in the drama in the tallest building on the Chinese mainland, which is dubbed "Bottle Opener" because of its shape.

The Oriental Morning Post said the elevator is the fastest in Shanghai with a maximum speed of up to 10 meters per second. Its manufacturer, ThyssenKrupp, also conducted an investigation and sent six workers to check other three double-deck elevators in the building.

The newspaper said the faulty door controller had been removed and sent to ThyssenKrupp's German factory for examination.

Wang said the elevator broke down on March 30 when a power outage hit the Lujiazui area, but the error record was not cleared in time.

The bureau has ordered the Shanghai World Financial Center to stop using the elevator until all errors were fixed.

ThyssenKrupp said it will strengthen the maintenance of the four double-deck elevators.
