Thread: plasma on PTO winch?

I'd check with Thomas. I know some Warns bend drums with plasma.

the drum seems heavy duty but in saying that i have not compared with a warn drum

i assumed it was a straight forward yes but didn't think about the drum

i know i dont have to worry about heat build up

i cannot find a hawse fairlead wide enough for the PTO....no differant to that problem i currently have with the wire rope

i considered making a custom roller assembly........but never got there

Elaborate please....

I'd like to know more about that!
The only way I could see it happening is by larger rope being fitted and nuff nuff operators assuming that greater rope strength will give them greater pulling power and overloading the winch.

On the plus side for Plasma on a PTO winch, at least heat buildup would not be as much of a concern.

Here is where I read it. This was done in 2009. Tug of War: The Ultimate 12v Winch Test

"The load rating verification test was the one that presented a problem. Initially, we mounted the winch to the Ramsey winch plate, which we had already tested to over 12,000 pounds when we tried to stall the 9500 UT. Unfortunately, when the Endurance reached a pulling force of 11,560 pounds, the case casting on the gear side of the winch abruptly fractured and the winch simply came apart. The drum began to separate and twist, fracturing the motor-side casting, allowing the line to pull the winch (no longer attached to some of the feet) into the front of the plate and the fairlead, bending both of them. We had to cut the anchor strap anchoring the back of the Jeep to remove the load from the line.

We contacted Warn about the situation. They were extremely responsive, and overnighted another winch to us, along with one of their own production winch plates for the JK. They postulated that some sort of deflection in the Ramsey mount—designed, after all, for a 9,500-pound winch—might have caused the failure. We were receptive to that possibility and happy to give it another go with the Warn plate. We removed the Ramsey plate and installed the Warn unit, noting that there were significantly more brackets, braces, nuts, and bolts than provided with the Ramsey plate. The installation took a bit longer, but was fairly easy.

With the new winch mounted to the new plate, we repeated the load rating test, and this time the winch successfully pulled to its full 12,000-pound capacity. After the test, we unspooled the rope and discovered a dent in the drum near the gear side. Once again, we contacted Warn. They informed us that their winch drums are not intended to be used with synthetic rope when the load is in excess of 9,500 pounds. A quick perusal of the synthetic rope product page on Warn’s website indicates that only their own rope is approved for use with their winches. It has a high-temperature urethane coating and a Nomex sheath along the length of the first drum wrap to provide additional protection from drum brake heat. Additionally, the page states that the rope is for winches with a 9,500 pound pull rating or less. We have been aware of a phenomenon with synthetic rope that creates a constrictive effect under extreme tension, which can damage winch drums. The surface properties of the rope (very slick) act differently on the drum surface than a steel rope which has some degree of friction and a less pliable cross-section. Apparently, this is one of those cases."

I am no expert this is just what this article wrote.

I'd hazard a guess to say that the Dyneema rope constricts to a smaller diameter under load......

APE (previously Thomas) make one. Do you have the 214mm drum? If so I'd be chasing down a Perentie bar and fairlead. There's an auction coming up I read here somewhere down at Bandiana. You may pick one up cheap. I got a Perentie bar and fairlead for less than $500, just took some searching. You'd have to modify your dumb irons though.

Just some ideas, don't you love Defenders, a 100 ways to skin a cat.
