This is a picture summary of the crane failure at 110 3rd Avenue which occurred at around 4 PM on Friday afternoon 30 Sept. 2006. There will perhaps be as many as 4 more posts covering this event with the last post being a detailed analysis of the event with close-up detailed pictures of the structure of the crane .

Late Friday afternoon a tower section fell from a Favelle Favco tower crane at 110 3rd Ave. , hit the street , bounced and dropped on a cab in the street crushing one side of the cab injuring 2 people . Three workers were injured at the top of the crane as a significant unexpected and seriously damaging abrupt movement and a jolting halt tossed them about the interior of the crane tower and operators cab . The abrupt halting of the movement also apparently broke loose the tower section which had just been removed from the tower assembly and was being prepared to be lowered to the street . The abrupt movement of the upper crane assembly also very nearly tossed 40000 lb.s of counterweights to the street which would possibly have resulted in the toppling of the large upper part of the crane to the street . According to a vague report from Department of Buildings engineers today , the crane suffered a hydraulic system failure .

As more information is made available and as I can piece together information recieved from individuals who were at the top of the crane and saw for themselves the damage caused to the crane by this peculiar event , I will attempt to present a more detailed analysis of the failures that caused this near disaster in a later post .
