Ok recently there was some test done on a winch. Seems Mile Marker Contracted a Company in Atlanta to test the Warn 9000 and some testing of the 9500.
While I think the way they tested the winch does not reflect how we use it there was a VERY interesting point that was brought up. Seems that MANY of the winches we use are rated more than the cable that is supllied with them can handle. This means the cable on the first wrap of the drum will break before the winch stalls and poses a safety hazard that you need to be aware of. If your REAL stuck you need to strongly concider double lining to lessen the risk of the cable failing and possibly injuring somebody. Most of the winch that are rated 9k and above are effected regardless of the manufacture.
Here is some E-Mails that were exchanged among the club I'm a member of, The Gerogia Bounty Runners.

Hi Ralph,
We ourselves have recently become aware of this report. We have
given it to our engineering dept. for review. We also have concerns and
questions about these Milemarker sponsored test results. We believe
these
were "dead head tests", where the tests and the results are not an
indicator
of real world results. We have made quality winches for 40 years. We use
the
best wire rope, and they do meet the requirements and specifications
for
these winches at the rated loads. I have included your Email address on
the
list of folks we will be providing information to on this subject, once
our
engineers have completed their review. We will be back to you with
further
information in the future.

regards,

Mike Wilson

when i am pulling myself out i am in the cab. everytime i have broken a cable it has gone way over the roof of the truck. i have good footage of an Aussie getting a cable accross the bridge of his nose. he was lucky as a few other people were hit in the arms and legs so they somewhat diminished the force his face took. it is on the TransPen '94 or '95 video i recorded off of speedvision.
 
Grim thank you for the time in looking all this up for us it's people like you that make this site what it is thanx man real GOOD info.

Thanks for the safety reminder when using winches. I have seen a steel cable snap before, and the speed and force that results is truly something to respect. If someone were standing in the wrong place, a direct hit from the snap back could easily cause death or dismemberment.

Have you seen the new winch lines offered by Master-Pull? I think they offer a much saver solution. This line, known as plasma rope, is made of Ultra High-Moleculear-Weight Polyethylene (UHMW-PE). It is stronger than steel cable and has very little stretch. When it breaks, it tends to drop to the ground, unlike the whip back from a steel cable.

There's a write-up on the Master-Pull Winch Lines in the September issue of Four Wheeler on page 132.

Yeah I recently got to look at some. Freaky stuff! Soft as can be, flops around like clothes line. Weirds people out when they see it get used but the guy loves it. Never gets bird nested and never gets splinters. BUT PRICY!

It's not my damn planet monkey boy!

Saw some on an old Land Rover this summer, man it looked weird. But, if it does all Master Pull says it does I think it's a great option.

Is there a website or somewhere to get a look at this line? Sounds pretty cool.

Yep, broken steel cable under tension will f**k your day up. I know a guy who witnessed a cargo winch cable break while pulling a helicopter into a C-5 cargo plane. The helicopter was being pulled up the nose ramp, and the winch is located in the floor of the rear ramp. The cable broke right at the end fitting, went the whole length of the cargo bay (over 100ft), and hit the rear ramp doors hard enough to break the aircraft's skin and a reinforcing rib. He said it sounded like a rifle shot, even over the noise of the APU's. It's now against Air Force regulations for personnel to be in front of the cargo being winched into a C-5.

I was wondering about the heat problem my winch is mounted between the frame rails almost right under the frame rails! The max heat this line likes is 275 or so. Also how does it hold up to rocks and such. Almost ever time I use a winch the line is in to the rock at some point during the pull or a tree or something. As for the cost new cabel is about 1/2 but 5/16 cabel has a low break point. SO should it be compaired to 3/8th for the 5/16 line? Lastly maby we could get Steve to set up something though the membership.

They are much less abrasion resistant than steel, it is important to put a floor mat, etc, against any rocks that it is sliding on. As for trees, you shouldn't be doing that in the first place.

You could put a piece of sheetmetal above the winch drum to act as a heat shield of sorts.
Or you could put the sheetmetal under the radiator (assuming that's the heat source you're talking about), above the winch.

Motor, radiator all of that is close by and can be above 200 deg. Just think would it live on my winch or not
