Seems like bad reporting here.... “A construction crane collapsed.....” Was there a third as the pictures clearly show two intact cranes?”
no third crane evident and no crane parts in the wreckage ... almost guaranteed they were pulling forms before concrete was cured enough ... that’ll pancake things real quick ...
Agreed Cat. Looks to me like the 2 tower cranes survived, (but compromised no doubt). The grey colored box configured steel wreckage shown on the ground in one of the pix, (that looks like part of a collapsed yellow tower crane), appears to me like the building’s exterior shell, vertical steel guide/support rail system that the temporary construction ‘man lift’ elevator rides up and down on, was peeled away from the exterior shell as the floors above came down and ripped/pulled the rail system off, and then ended up on the ground. The video of this accident shows an additional angle also. Well, we will see I guess.
It was a steel framed building with metal deck. It wasn't a concrete framed building.
