If a rock truck "doesn't need that much power" then please explain the latest version cat 979 haul truck. It's engine is a 20 cylinder, 4 turbocharger monster that makes 4,000 horsepower.
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.

Roughly 528 ft. per. day in a deep cut and twice that in a shallow cut.

As an operator, Miller praised the 6360 Captain shovel. “She was a wonderful machine; nothing could touch her when it came to production. When I was on her, we regularly dug a complete pit one mile long from end to end in only 10 days. We regularly turned in production numbers showing more than 7,000 cubic yards per hour,” Miller boasted proudly. “The east half of the pit, where the overburden reached 100 ft high, the Captain dug this in only five days. When we took over with the 5900 shovel, this same section took 11 days.” Production numbers obtained from Arch Mineral confirmed Miller’s experience. During her active life, the Captain shovel moved 809,300,000 cubic yards of overburden, a number far greater than any other single shovel or dragline.

Side note.

Electrical equipment on board included eight hoist motors rated at 16,000 hp, eight swing motors provided 10,000 hp, and four crowd motors added another 4,000 hp. A total of 16 propel motors, one at each end of each crawler unit were rated at a total of 3,200 hp. Of course, not all these motors ran with maximum power at the same time, but the machine consumed enough electricity to serve a town of 30,000 people.
