I was down at our wire rope guy's place the other day talking with him. 2.50can$/foot. Dont remember the brand, but he supplies it to the S&R, the helicopter guys etc.
Pretty impressed. I'm sure 100' of that stuff weighed the same as a quart of oil! At that weight, it be good to have another 100' to throw in the back for extra distance etc.
And talking about it breaking, he showed how easy it was to just splice it and your good to go.
Now for some money...

|obidya||are there any special precautions you should take in caring for your synthetic rope?|

It was just one of those weekends, particularly Saturday. If something could have gone wrong that day, it did.

I'm betting those broken synthetic ropes were 5/16". So one thing about switching to synthetic ropes... you may be replacing a 5/16" wire rope but even though a 5/16" synthetic rope is technically stronger, you really still need to go to a 3/8" synthetic. The simple answer why is synthetic rope is simplier easier to abrade on sharp rocks etc. than a wire rope is so you need a bigger safety margin with it... 3/8" synthetics typically have at least an 18k lb. breaking strength which even when slightly abraded, means it will usually still hold & be safe.
So when going with a new synthetic, I personally believe you need to go with a 3/8". Having 3/8" synthetic ropes on both of my TJs for about ten years now, never a problem or broken rope.

Feel free to cheap out on whatever you want; in this day and age you can find cheap versions of just about anything. Personally, I see recovery equipment as one of the last places to cheap out on. When it comes to safety, particularly the safety of those around me (like my wife who is typically with me), I have a hard time using sub-par equipment.
Viking sells high quality stuff and stands behind their products. Not to mention their support is hard to beat.
Just make sure you're getting rope made with Dyneema SK-75 fibre. At least I would.

|geiman||I run rollers with my synthetic line without issues as well. That being said, when I get the chance to pick up a hawse fairlead with a nice large radius I will definitely do so. The roller fairleads are pretty darn heavy.|

|1jeeplvr||Prob a dumb question but why get a synth rope that is rated for 19k lbs when the winch is rated for say 8000 or 10000 lbs? If the winch can only pull that amount why go higher than the winches capacity.Just askin.|
|06-06-2013 12:34 AM|
There is nothing you need to do to your drum to convert from wire to synthetic rope. If you have a roller fairlead with rollers that are nicked/damage from wire rope use, just use a file or grinder to smooth it.
When comparing wire to synthetic rope, synthetic truly is stronger by breaking strength. 5/16" wire rope actually has a breaking strength very close to the winching capacity of many of our winches, close to 9500 lbs. 5/16" synthetic is closer to 12,000 lbs for most brands. I use 3/8" with over a 19,000 lb. breaking strength simply for its added safety margin since synthetic is definitely more susceptible to damage from abrasion. I won't recommend 5/16" synthetic rope since while it is stronger than wire rope, it can be damaged more easily if it had to be dragged over a sharp edge/rock while in use. In 10-12 years of using a synthetic rope on rock crawling trails however, I've never encountered a situation where that happened. Possible, but not all that likely.
Hope that help.

|1jeeplvr||Thanks for the info.I think Ill need to replace my cable as someone ran it over on me!!!! Anyhow,is there something I need to do to my drum to accept a synth cable? Also,in my mind I cant understand how a rope can be as strong as a steel cable.It makes me a bit hesitant to replace my steel with synth.|
|05-23-2013 08:22 AM|
Like geiman said, I wouldn't run a line without one. I'd go further and say I'd be suspect of a company not equipping their winch line with one.

One of the most basic and easy to follow rules of rigging is to make the least number of connections necessary. The Safety Thimble follows that rule better than pretty much any other hook or thimble you can buy. Look at the end of a typical synthetic line:
The first is typically called a tube thimble, and I believe the second is simply referred to as a thimble and is typically the style seen on steel cables. Both of which protects the line and helps it to conform to the minimum bend radius. You then typically connect a hook to the thimble:
While there isn't technically anything wrong with this setup, you're adding an additional connection that can be avoided with the Safety Thimble. If you look at the Safety Thimble, you'll see it's actually taking the place of the traditional tube thimble, and avoiding the need for the additional connection which better adheres to the "least number of connections" rule.
Also, the shape of the Safey Thimble allows either end of a typical shackle to fit through (I want to say 3/4" shackle, but don't quote me on that), which allows you to use one shackle to connect directly to the bumper of another vehicle. The next size up shackle (5/8" if I'm thinking correctly) will let the pin through, but not the body.
Finally, the Safety Thimble gets it's name from the fact that it's safer than a traditional hook. With a hook, there is the chance of getting a gloved hand caught on it and possibly sucking your hand into the winch. The Safety Thimble won't allow this, and cannot be sucked into the fairlead.
I'm not sure if the Safety Thimble is used much with steel cable, although I do know that Tough Stuff Products has instructions for installing on a steel cable on their site:
Winch Safety Thimble
Blaine (Black Magic Brakes on here), is the creator of the Safety Thimble and would be the one to ask about that.
There are other products out there, and one "thimble" in particular to watch out for is the one Factor 55 produces. I wouldn't recommend it, and go further to say it isn't truly a thimble and more so just a fancy, expensive piece no more useful than a hook. You can read here for more info if you're interested:
Factor 55 shackle mount - JeepForum.com
With all of that being said, a thimble of some sort is very important on any winchline, and I would never run a line without one.
I am by no means an expert, merely an enthusiast, so take this all for what you will. I also highly recommend anyone getting into rigging to read as much as possible on the subject. This is a good start:

I said it before & I'll say it again... conventional synthetic rope is fine for our winches when used in the forward 'In' winching direction. No heat is generated from the brake in that direction. In 15 years of winching, I've yet to lower a vehicle down backwards in the Reverse 'Out' direction where brake heat could create a problem for a synthetic rope. Not to mention Warn's heat resistant synthetic rope was selling for $800 the last time I checked. It's all about their lawyers doing a CYA.
|05-21-2013 05:17 PM|
|1jeeplvr||Why is the thimble so important on a synthetic rope? Is it equally important on a steel cable?|
|05-21-2013 11:35 AM|
At the end of the day, if the heat issue was as big of a problem as you're making it out to be we'd be seeing it all the time across the various boards where this stuff is being used. You can see how people love to get online and complain as soon as something they buy goes bad, so I can only imagine the backlash if this problem was more apparent.
Like Jerry said, I just don't think it's a big problem for the typical use most are seeing.
That being said I do think it's something every owner of synthetic line should be aware of just in case they find themselves in that particular situation, but I really don't think it's enough of an issue to push your favorite winch brand over.
|05-21-2013 11:25 AM|
Jerry, if it were a non issue, why would WARN put a weaker and heavier rope on their synthetic-equipped winches? To handle the heat, a lesser rope than Dyneema SK-75 amsteel blue is used.
I think these guys (Warn and Superwinch), two of the last to build winches in the USA, are probably on to something.
Add the Superwinch Talon to the list of winches that don't add heat when powering out - it's brake is outside the drum.
Also from Superwinch's website, "Warning: Synthetic rope cannot be used on this off-road winch. Synthetic rope can only be used on winches with steel drums designed specifically to withstand the rigorous forces created-by synthetic rope; for example the Superwinch Terra Series, the Danny O'Day S4000, the S4000SR or the Talon Series. In addtion, the heat generated by the brake which is located inside the Tiger Shark drum exceeds the heat limitations of Dyneema synthetic rope. Many of our competitors will sell you a winch with a similar brake in drum setup with aftermarket synthetic rope and will not warn you of the damage which may occur to the winch, rope, vehicle or injury to the winch operator."

|Barmanvarn||Subscribed. How much cost would I be looking at to go to a synthetic?|
|05-16-2013 09:29 AM|
The heat problem you are describing has nothing to do with normal 'in' winching, that particular problem only occurs when you are using the winch in its Reverse direction, like if you were using a winch to lower a vehicle backwards down a hill which places its brake into operation. It is the brake that generates the heat which only becomes a problem when using the winch in its Reverse 'Out' direction.
In the usual 'In' direction, drum heat from the winch brake is not an issue. Many people worry about that heat when they get a synthetic winch rope but for 99.9% of winching operations, it is a complete non-issue. The only winch commonly used on our Jeeps I am aware of that doesn't generate that heat in the reverse direction is Warn's 8274.
|05-16-2013 07:42 AM|
It has nothing to do with Superwinch, but with where the brake is. In most winches, the brake is in the drum. Dyneema synthetic rope (the good stuff Viking sells) begins to distort at just 150 degrees. Powering your line out heats your drum and thus the rope.
We put a heat gun on a Smitty and after powering out it's rope the temp was over 220.
The other problem that was mentioned is how much this rope wants to dive down between layers. In loose layers, that makes unspooling it tough. In pulls, it can put so much load on the drum as to push the flanges apart. This will either bend the flange (winch stops) or split the drum tube like taffy (drum flys out of winch). This happened to Overland Journal when they put synthetic on a Warn.
Can you keep your winch cool? Sure. Can you take extra care in dressing your rope and not side-pulling? Sometimes.
It's all risks and rewards. Me? I'd rather have a winch that was built with synthetic from the get go, with a brake outside the drum and beefed up drums.
But I am biased.
|05-16-2013 07:27 AM|
You need to hook your line up to something and pull your Jeep while the brakes are lightly applied to properly tension the line on the drum. If you don't preload the line properly, it will suck down into line on the drum like you've experienced.
|05-15-2013 11:36 PM|
|Klep||I lost 3/4" up front adding my bumper and winch which came with steel cable then switched and probably shed 12-15lbs by losing the heavy cable and roller fairlead. One thing I have noticed and maybe I'm not properly re-spooling the line after using but my line that's being winched back in around the drum will imbed between the wrapped line under heavy load and it can be difficult to pull out by hand when you go to spool the line up evenly after a pull. I never used my steel cable so I don't have the comparison but I doubt the steel would mend under heavy load. Go synthetic though, it's durable, light weight and it looks good too!|
