- The roads in that area are no joke and I think it takes more crazy than courage to do this... with any brand of light duty truck. I'm sure DOT or local police would have shut down that show if they saw it.
- I would hate to be the one who is the next owner of that pickup.
- Seems to me that you don't need a lot of power to do that. Has the weight for enough traction, and the torque from being in 4Lo. If he would've done it in 4HI, then I'd really be impressed.

Actually about 5935 lbs.:)mkirsch wrote:

Rolling resistance of hard tires on a hard surface is very low. He wasn't exerting more than 2-3 tons of force on that chain.
Entirely possible, even with a normal truck, and not at all worthy of any specific bragging rights.
You are correct on there not being a huge amount of force on the chain. 140K on a 6% grade I'd WAG that at about 8000 pounds of tractive force required to move the load, plus rolling and mechanical resistance. That may not sound like much, but it's like driving your truck up a vertical wall. The really hard part was getting it rolling, which I guess would have taken about 11,000 ft./lbs. of rear wheel torque to make the tires move, based on 140K of weight, 6% grade and 32" tall tires. To figure out if your or my truck could do it, just multiply torque x your low transmission gear x low range xfer case ratio x rear axle ratio and see how the math works. If someone is an engineer with a propeller on their head feel free to correct me if I'm in error. Or you could just hook her up and see what happens.mowin wrote:

Eh, not impressed, come back to me when a truck can pull the space shuttle.
A yugo could have pulled the space shuttle.
Men have pulled Boeing 737s with their teeth and beards. I doubt the space shuttle (without boosters and main tank) weighs more than a 737.mowin wrote:

not sure what all the comments about the brakes are about, as long as the air tanks are full, the brakes will release, he will run out of air after a couple brakes and then the brakes will lock till he gets more air, or manually over ridden, but you most certainly do not need the truck running
If he had a tank of air, than yes the brakes would release. Wouldn't take to many taps on the brakes to deplete the air, so you would need the truck running to keep the air pressure up. That and most trucks I had the pleasure of driving, lost air pressure at a steady rate when not running.
Same experience with me. You can not count on the air staying in the tanks very long.

I wouldn't abuse my vehicle like that.
Q1. If the logging truck was broke down and not running how did they get the air brakes on the trailer to unlock?
Q2. Was the space shuttle not available?
As long as the air system does not have any leaks and was up to pressure it will have several stops before the brakes lock up. That happens between 20/30 PSI with an alarm @ 60 PSI. So if he started with 120 PSI and a tight system he will be fine.
I do agree with your comment about abusing my truck, not a snow balls chance in hell.

Winner! Winner! Chicken Dinner... If the Power Wagon could maintain traction it needed no where near the engine power it has to pull the log truck...
