First, I suggest heating each nut from the bottom and then let them all cool. If you don't have an gas welder setup, a propane torch will do. This will help loosen the bond between the nut and the bolt.

Then, take a 4" angle grinder with a thin cutoff wheel and slice a slot into the top of each carriage bolt. Then you can prevent the bolt from rotating with a BIG screwdriver and have someone underneath wrench the nuts off.

Cheers, Dean
