As an old crane operator, I couldn't help but notice that the crane on the left may have been the culprit ( or accomplice ). If you'll notice, the bridge comes down on that side but even closer inspection reveals that the crane remains stationary while the bridge collapses. Look at the swing weights on that crane and you'll also notice that they are going down as the bridge goes down. If that crane was doing it's job, it would have been pulled over or at least rocked off balance.
My opinion is that either the brake failed or the operator released the brake from the load. The only other explanation I can fathom is a fault in construction at the point of support while the crane was still hooked to the load without support. It is not common practice to be hooked to a load with the drum not in gear, too easy to hurt someone. Until free from the area operators don't use a manual free fall brake.

Come to think about it, free fall was best saved for dropping the hook into the coke barrel while the riggers were getting warm.....Bwahahahaha good times.
