Investigators were this week trying to establish what caused the failure of a cable crane that led to three steel beams plummeting 40 storeys at the World Trade Center (WTC) construction site in New York
Officials said no one was hurt when a crane cable broke at about 10am local time last Thursday sending three 30m-long beam weighing an estimated 17t crashing down onto the flatbed truck that transport them to site. No one was injured.
The accident occurred at 4WTC – a 72-storey development to the west of the main WTC building. The accident caused construction work to stop on the WTC4 site, but the main WTC building work was unaffected by the collapse.
“We are investigating the matter in full cooperation with the [New York and New Jersey] Port Authority, FDNY [Fire Department New York] and NYC [New York City] Department of Buildings,” said a spokesman for construction manager of the project Tischman Construction.
WTC was designed by consultant Maki and Associates and funded by developer Silverstein Properties.
