It carries 400 tons at over 40mph.
Fuel capacity is 2,000 gallons on 2009 and up cat 979F.
It's a truck with a train engine.
Explain how a truck with a 2,000 gallon fuel tank and 4,000 horsepower engine doesn't really need that much power.




I have seen that. The world's biggest power shovel runs electric, but the distance it moves is measured in feet if not inches over hours.
It's almost stationery.
The rock truck is more like a taxi, for ore.
that 4,000-hp engine requires 26,666-hp worth of energy,from 'well' to wheels.With straight electric power from renewables,you skip the the 85% waste.And that's also why we don't need to build a renewable power grid with the capacity of current demand.
