I am confused. Is your point about range or power? There are already electric heavy construction vehicles (cranes, ore haulers, etc) but looks like most are hybrids for power generation or use heavy cables. So the electric motors are capable of the work, we just need to get better at batteries for an all electric mobile solution.
You are getting the idea.
Under current technology, BPVs (Battery Powered Vehicles) are limited.
Diesel Electric units like locomotives are definitely practical
Pure electric trains are limited to where the wires are but not as bad as BPVs..
