A Rough Terrain crane overturned sideways onto a five storey development in Winchester, Massachusetts - on the north side of greater Boston - on Tuesday, slicing though the building.
Thankfully no one was injured in the incident.
The cause is clear, the operator had installed and offset the swingaway extension and then telescoped the crane’s five section boom to almost full extension amazingly with the crane still free on wheels, having made no attempt to set the outriggers.

Not surprisingly the crane, on of the larger Grove RTs, went over, with the boom landing on the building and the dynamic effect of the collision buckling the upper sections of the boom.
OSHA - the Occupational Safety and Health Administration - is investigating however it ought to be a relatively quick one. The video below was filmed shortly after the incident occurred. The developer of what will be a 96 unit apartment complex is Strategic Land Ventures.
