Nasty way to set precast.
I could have probably avoided the whole thing. The contractor had bare rented the broderson. Called me to just unload the trucks.
He was going to use one of his guys, who has never run a crane, and try to set all the precast with just the broderson, they were 14,500lb pieces. The broderson got delivered with just ball in it, and they were primed to unload like that. I installed block in it for them, and told them I could probably get the panel unloaded, but there's no way to set them with just it, no head height for rigging and its not enough crane to spin them. But they could do what they want.
At that point, I could have just walked away- its really not my deal. But I could see a disaster coming, and did my best to explain how its really not enough machine to do what they wanted to do, even though the rental salesman told them it was- its a 18 ton machine, why couldn't it set 14,000lbs? "Well maybe we can have you come set them". I'm always glad to have work.
I told them I would tandem pick them with my galion and the broderson, and was only going to do it with my operators. No way was I trying to set them up under that roof with a new guy. My operator is a really good hand, so we could just carry them in, and set them. No training required.
Job went really well, considering the room constraints we had.
