It depends on what the empty weight of your combination (tractor plus trailer) is. You're allowed a total weight of 80,000 lbs., so, you subtract the tare weight of your tractor and trailer from 80,000 lbs., and you're left with what you can haul legally.
The type of tractor trailer that can hold the heaviest loads is a Semi-Trailer truck. This is the heaviest truck that is allowed on the roads.
The "tractor" is the vehicle which actually powers the combination. A semi-trailer is any trailer in which the weight of the trailer (and the payload) is shared between the trailer's axles and the axles of either a dolly or the towing unit (in contrast, a full trailer supports all of its own weight).
