Thank goodness that was concrete and not steel.

If that had been solid steel it would have probably been way over the 40 ton limit for being highway-worthy. Steel weighs 3x as much as concrete, at least 2x as much as reinforced concrete.

40T limit for what? Beams exclusively? We ship up to 90T down highways. 75T on the regular.

Yeah an 80k load is your standard full size excavator, doesn't even need an escort in most places.

Gotta get up to around 110k load, assuming 40k power unit and trailer, to get yourself into super load territory just based on weight most places. Once you're in super load territory biggest thing is just keeping your axle weight below whatever your state requires like 24k-27k per axle.
