The Electrical and Mechanical Services Department (EMSD) has launched an investigation after an elevator at a residential building apparently went out of control and seriously injured a couple in Tsuen Wan.
The incident took place at about 5 p.m. Sunday, when a man and his wife, both 32, entered the lift at the ground floor of the 46-storey Block 2 building of Waterside Plaza on Wing Shun Street, Apple Daily reports.
After they pressed the button to their flat on the 15th floor, the lift suddenly ascended at an abnormally high speed before it smashed the top of the lift shaft on the 46th floor.
The couple were thrown against the wall of the elevator and hit by fragments falling from the lift’s ceiling.
Responding firemen rushed the couple to Princess Margaret Hospital.
According to the CCTV footage, another passenger took the elevator with the couple but got off on a lower floor before the lift ran out of control.
The 27-year-old building has three lifts, Nos. 4, 5 and 6. The owners’ corporation of the building decided to replace the three elevators last year. Only No. 5 is currently suspended pending its replacement. The couple took the No. 6 lift.
Lo Kok-keung, a fellow of the Institution of Mechanical Engineers and a retired engineer at the Mechanical Engineering Department of the Hong Kong Polytechnic University, said the accident might have resulted from the simultaneous malfunctioning of the elevator’s brakes and motor.
Wong Kai-hon, chief instructor of Pro-Act Training and Development Centre (Electrical) at the Vocational Training Council, agreed with Lo’s conjecture.
The building management said it will fully cooperate with the investigation. It has suspended the operations of all of its elevators until the maintenance service provider has inspected the units.
Waterside Plaza, which has four residential blocks, saw a similar accident back in January 2014, when an elevator at Block 1 also ran out control while ascending and smashed the top of its shaft.
