Hi, I am looking for info on winches... size - 8000 or 10000 lbs, type - smyty or warn, wire rope vs synthetic rope
-
What sort of info are you looking for? There's a lot to cover. I toss out some info....I didn't come up with it, but I think it's pretty accurate.
First, this is probably worth reading:
http://archive.org/details/Fm20-22VehicleRecoveryOperations (http://archive.org/details/Fm20-22VehicleRecoveryOperations)
Then, when you're buying a winch, here are some thoughts:
If a vehicle is mired to the where the tires and the wheels meet, you will need a pull equal to it's weight to get it out.
If a vehicle is mired to the hubs, you will need a pull equal to twice it's weight to get it out.
If a vehicle is mired to it's body, you will need a pull equal to three times it's weight to get it out.
Also understand that most winches will only pull their "rated" amount when on the last or second-last wrap (closest to the drum). As you move outward, you may find that the effective amount of pull delivered is cut down to about 70% of the "rated" pull. If you're really curious, look at the line-pull rating charts on the winch manufacturer's websites. I know that Warn lists the line pull for each layer of wraps on their winches.
So: 8000 pound rating X 70% = 5600 pounds single-line pull or 11,200 pounds double-line.
4500 pound Jeep X 3 if it's really mired = 13,500 pound pull needed.
What does all of that mean? You may be all right with an 8000 pound winch...but you may not. I personally spent a few more dollars for a 9500 pound winch.
9500 pound rating X 70% = 6650 pounds single-line or 13,300 double-line.
Some folks like Warn. Lots of folks that the KingOne winches that Lemon-Aid Jay is selling are a great buy. I'd have no issues running either one.
Wire rope versus synthetic? I've run both....and after switching to synthetic, I'm never going back to steel cable. Others will argue the point.

If you decide before monday, talk to Jay at Chanda... hes running a 20 percent sale on the king ones. A 9500lb wih steel line will be little then 600.

Completely agree. That's why they look so good on YJ's. Zing.

Thanks Guys..... :)

550 for an 8274 in good working order is a great deal. That winch will probably outlive your Jeep. And my Jeep. But not Trevor's XJ. He'll keep that thing in a state of suspended animation just to spite me. :o
