The most serious injury was a broken leg sustained by a worker. All the injuries were confined to the construction site, which is behind the iconic Pepsi-Cola sign on the East River. Two of the injured workers were taken to Elmhurst Hospital Center, two to Weill Cornell Medical Center and the rest to other local hospitals.
The cause of the accident remains unclear.
The incident happened at 47-27 Center Boulevard, near 47th Avenue in an area that has seen a burst of residential construction in recent years, mostly tall glass towers.
The crane collapse is the second prominent failure at a construction site in recent months.
A crane famously dangled from the top of a midtown tower under construction that was loosened during Hurricane Sandy.
