Just to pose a question: Don't you double the pulling power by adding "arms" to your pull (I don't know the technical term; i.e. you pull your cable to a tree, use a shackle, then pull the hook back to your rig) "\ /" pretty much. If so, then would more cable be beneficial for a really stuck vehicle?

A pulley AKA snatch block will double the pulling force but half the effective line speed. It pulls half the weight but half as fast as a single pull. Tradeoff speed for force. I suppose that more cable would be better in that situation since you cut your pull length in half too by running the same amount of rope. Example: 100 ft of line, with snatch block is approximately only a 50 ft reach.

yep...each pulley doubles strength, but cuts speed in half too.

Rope is lighter,safer, but be careful, it's very easy to cut it on a rock etc...

I have about 80 ft left after a couple breaks and re-splices.

x2. you can get some cheap abrasion gaurd from any rope supplier. get the flat hollow nylon rope and slide it over the winch rope.
 
my amsteel 5/16 is not uv protected has faded and become a lot weaker than when new.
I would buy 125' put 75' on the winch and keep the rest for an extension.
I just tied a bolin for the end after the fancy spliced end broke off.

Also, they say it doesnt store energy (will not go flying if it breaks) but it will espically if you use your tree saver as most of them stretch.
 
5 - two on the front, two on the rear, and one in the winch controller/tree saver bag. Over kill, but I don't want to have to look for one when I really need one.
 
i have 125' of rope on the drum with excel hook and a backup length of the same set-up in the truck incase of failure of the main line. can also be used as an extension.

i have been buying from http://www.customsplice.com/ and prices have been fair and shipment is quick and accurate. even have gotten a few discounts thrown my way for being a repeat customer.

later.
 
i have 90' on my m15k,a couple shackels and 2 snatch blocks...and if yall think using snatch blocks doubles your pulling power youre wrong,it evenly distributes weight on two lines and reduces line load...yes it is a mechanical advantage but it does not double your pulling power
 
I've noticed on competition winches that have like 50' or so of line, I know a couple of the 100 and less are comp folk, does that have anything to do with the amount of line you carry, vs say joe schmoe out in the woods. I guess it really boils down to preference, but a lot of the people in the poll have been doin this a long time so I figure they hafta know a thing or two.

I've looked at conversions and _I_ think I'm gonna go with 100' of 3/8 and get a bubba strap, a safety thimble, a UHMW Hawse Fairlead(sky offroad 25$), and some d-rings. I dunno if anyone ever suggested. 3/4 or 7/8?

No, Sir. In fact, you are wrong. In a situation where the vehicle is moving, you are somewhat right, but when pulling on a stuck, immobile vehicle, it is 100% fact that it doubles your pulling power.(unless you're a dumbass and don't fasten the end of the cable back to your rig. then a block does 100% nothing)
 
I got bad stuck Sunday. My buddies 8k warn wouldn't budge me. We put a snatch block on my jeep and eased me out no problem.

I'm headed today to Rides to pick up my winch. After the steel cable wears I'm probably gonna go with synthetic. Definitely gonna throw in a snatch block. Worth the money in my opinion.

If you run a line out from your winch to an object, through a pulley and back to the winch, the total force between your vehicle and the object is doubled.

The same goes if you run the cable out, through a pulley, and then back toward your vehicle but to another immovable object.

This still works even if the angle of the pulley at the far object isn't 180*. If it were 90*, you'd still have the winch's rated capacity times the square root of two (~1.4).

The only time a pulley wouldn't act as a force multiplier is if you were just using it to change the direction of the line, and the object you wanted to move was still at the far end of the cable.

Sorry Shawn, but this is wrong. The only way to increase pulling power on the stuck vehicle is to run the cable through a block then BACK to the vehicle. Maybe I will get some time later on to draw a free body diagram.....
 
Free body diagrams don't lie. (Engineers, please disregard the laziness of my freebody diagrams. I should have had an opposite facing force due to stuckiness, but the drawing was cluttered enough as is :flipoff2:)

I think that is what everyone here is saying, line out, through pulley block, then back to vehicle.

But I do agree, it isn't 2x due to friction but then again I'm just being a picky little bastid :flipoff2:. But its close!

I guess everything he said is true, if you care about the force acting on the immovable object, but that makes little sense in the context of this discussion. What is pertinent is the force acting on the stuck vehicle.
 
Back on track...

Seems like most people prefer ~100ft of cable. Fortunately in this area of the US, we have plenty of large trees to winch off of. Even when using a pulley block (never for self recovery but usually to recover another vehicle and change line direction) I still haven't had any issues with line length.

Oh and synthetic is AWESOME btw. I've had mine for almost 10 years now. Still going strong. Looks like crap, but still going!

WTF are you on about?

Truck A is stuck.

Truck B is pulling him out with a winch attached to his vehicle.

Truck B runs a winch line out to A, through a pulley, and back in the opposite direction. It doesn't matter WTF the end of that winch line gets attached to so long as it gets attached to something that doesn't move much.

The force on A will be double. If the angle is less than 180*, you need to do some math to calc what the force is, but it'll still be more than 1x the capacity of the winch.
 
Oh... I see what I did there.

When I said "object"... I meant whatever thefawk it was that you wanted to pull out. You're the mostly-immovable object, pulling out your dummy friend that can't drive.

Carry on.
 
I run 125' of 1/2" synthetic line because I know it will get cuts and scrapes. After heavy use I have hopes of keeping a decent strength winch line rather than having a perfect sized rope (3/8") and with 1 or 2 cuts its nearly toast and "questionable" as to if its going to hold my buggy's heavy ass...

Ahhh yes, if you are pulling your idiot friend out, then i agree with everything you've posted. I was pulling my idiot self out, and i still agree with everything i posted too :flipoff2:
 
What a stupid argument. Everyone knows that only whack-ass people who get stuck have winches anyway. This is irrelevant information to real wheelers.

HEY! I take offense to that. In my case I was the dummy friend. LOL

what if your not stuck but flopped? Is that the same thing?

I'm waiting on some pics but the recovery was neat, a snatch block to my drivers side d-ring, (more for the angle I think) another line around the frame, and mine to a tree pulling forward. so it was forward, over and back on the wheels.
