A 330DL Cat with a breaker would be out of there in an hour, loading trucks included.
If that is granite (prolly) it would make more sense to rock drill those slabs for lifting eyes, pick them off whole onto some lowboys and sell the material. Would not be as fast as you would epoxy the eyes but it would make money. Shit, those could make some big countertops :)
Known by a few names - hydraulic breaker, ho ram, yes, and as you say, hammer. Very useful attachment.
