Wow thats one huge truck. I think I've seen this featured on Discovery Channel or Travel Channel. They mentioned there are only a handful of these in the world. Wonder what kind of fuel economy it gets. It would be fun to do an oil change on one of these trucks. I imagine the oil filter would be huge as well.
Interesting. My dad worked at Cordero Mine in Gillette, WY and back in the day, trucks this size were diesel-electric hybrids. A 'normal' sized diesel engine providing electrical power to the electric wheel hubs, which actually drove the truck. Braking was provided by a 'retarder', basically reversing the wheel motors to provide braking. Traditional brakes also existed, but for very limited use.
Strange that they've gone with diesel-only drivetrains in these monsters now.

i use to run a cat 769 and a 773. during the rainy days i would disengage the front brakes (you has a flip switch to do this) and take a corner a bit too fast while holding it at full throttle, tap the brakes which would bring the rear end out and power slide the thing around corners.
a buddy of mine was good at wheeling them. when they are loaded up 66% of the weight is on the rear end, which makes the front end very light. if you were in a low gear and ran over a large bump you could being the front end about 4 feet off the ground and then it would touch back down slowly.

I love giant trucks!! I don't know if 3400 hp out of 7150 ci is enough for me though
I saw that episode/special also.
True, very true.
How about ~10,000 ft-lbs of torque?

If you were wondering how they got the 797B to the work site...
Why not just drive it? If anything, the two trucks are a little wider than the big truck. The added length doesn't help either.
