Just curious to see if any of you have any data on how many pounds your truck can pull. The pounds would be measured at the ropes point of attachment at the truck. I have broken ropes before, I knew their rating but they were old ropes with some oil stains and minor damage.

I know their are to many variables here but lets just say:

1- Dry level pavement
2- 4 weal drive engaged
3- Empty

Lots of different vehicles

Spinning tires or rope snap is the limit.
 
more than any car:hmm3grin2orange: :chainsawguy:
 
I don't know about an exact figure, but i've broken tow-straps rated at 18,000lbs. before, and that was a steady pull not getting a run for it and see what happens. But i was on dry pavement in 4-low,empty, with posi-trac. If you have the traction and the power, obiously you have about 18,000lbs. of pulling power. But i could be way off too.
 
Wait a minute..

I have a special bull rope 5/8''...200 ft...that i keep special for pulling trees over and stuff of this nature.

Something that i think needs to be asked.

Is after putting a pull on a few trees...what is the true rating of your rope at that point???
 
This thread is going to get out of control real fast!! MY TRUCK CAN PULL MORE THEN YOURS and let the BS start...

I have a 2006 Dodge Ram 3500 Dually with a cummins diesel turned up. I know if I can hook to it I will move it!

And as for this take your dodge and find a good 4 or 5" tree and a chain you pull it out (even jerk it) or move it and i'll say sorry.

post before & after pic...
Ill be waiting
 
how much wood could a woodchuck chuck? give me a break!!! you might be a hack if you do stump removals with your pickemup truck. LOL:deadhorse: :sucks:

Rope is rated at a breaking strength, but the cycles to failure is what keeps a rope around longer. It is recomended to only use a rope at 10% its breaking strength each use and it will last a while. If a rope is rated at 10k lbs and used to lower 100 lb logs it will last a long time. The same rope used to lower 5k lb logs will not be around very long. Of course drop distance and other factors change the equation so that is why we have the 10% guideline. If it is used at its max every time it will lose its stretch and break sooner. Once a rope loses its stretch it has no choice but to fail. Unfortunatly it usually fails at the worst possible time.
Back on topic, a truck will pull a whole lot, usually more that the rope or tree can handle. An overeager driver can snap a rope quick when pulling a tree with a truck, I prefer using the truck as an anchor and setting up some pullies to get a steady pull. But if you do use a truck to pull eye contact and communication is a must.
 
Friction has the answer

You can usually only pull up to the weight of your truck with a static pull. If you get a running start, the pull is higher, but only for a moment. It's just like when you lower big chunks, the greatest force on the rope is when the weight catches.

Friction is dependent on the tire surface interface and what kind of weight you have mashing the tire down into that surface. The expression used for friction is a constant times normal force (weight on a level surface). The values of this constant depend on whether you are on asphalt, concrete, gravel, etc. and what grade of tire you have. Some coefficients for various materials can be found here:

Sorry to disappoint so many, but that's the way it is. If you want to pull a lot, you have to weigh a lot.

TT - One thing you left out of the equation is the effect of the rope angle on pull capacity. Simplifying the engineering model for this variable, a rope pulling at a 45 degree angle is un-weighting the truck in the vertical axis by an amount equal to the pull on the horizontal. This is why we sometimes don't place our rope as high in the tree. Many times, more horizontal pull at a lower angle does more good than the lever effect of having the rope higher in the tree. You can see this when you hitch up to the tree, throw it into 4-Low and start tugging... when your rear tires slip, guess what... you just saw the un-weighting effect.
