I was once told by a reputable excavator that the reason there are so many 20 ton excavators is because there is a limit on the weight of a tag along trailer. Excavator model numbers are about metric tons. Put a 20 ton excavator on a three ton trailer, some of the weight is on the hitch. Somehow the math works, 20 tons on the trailer tires?

Depends on the state. Here in IL, we only get 34,000 on a set of tandems so most guys with an excavator on a tag trailer run 3 trailer axles. I don't think you could get a 20 ton machine to "bridge" on a tandem tag.
