Evening all

One for the winch experts out there.

SS v Galv .. ?

7x19 SS .. 5106 kg Breaking Strain
7x19 Galv .. 6190 kg Breaking Strain

Both far exceed the average winch capacity. So for the pundits ... is there any reason, cost aside, that we shouldn't go for the SS.

It's more flexible and far longer lasting. Or am I missing something??

Over to you

Cheers

Hi Rosco,

Check out the synthetic winch ropes, 4B Equipment (one of the forum sponsors) has a B-Line 9.5mm 8,000 kg Breaking Strain one - just click on his ad to check his web site.
Might give you another option.

Kerry

All very well and good. Fine for competition, but it's my understanding they are very prone to abrasion.

I may well stand corrected.

Cheers

Rosco -

Must admit I dont know a lot about the synthetics maybe somebody will be able to give a comparison.

cheers

And apparently on mid mount winches should you have to winch yourself back down a hill the heat from the drum brake in the centre of the drum affects the rope reducing its strength. I suppose ultimately you end up at the bottom of the hill but faster than expected :o(

I'd love to replace mine but everyone I spoke to at the last 4wd show in Melb said XD9000 - uh uh.

Oh well $400 to spend on something else I guess. Every cloud has a silver lining.

Don't worry about stuffing the synthetic rope. If you are winching downhill with a planetary gear winch (brake in drum) then you should be worried about stuffing the actual winch!

It amazes me that people think winching downhill is a problem for the rope. These winches should only be powered out to release tension on the line and then free-spooled the rest of the way. They are not hoists. Any winch manual will tell you this. It is the equivalent of driving with the handbrake on.

Anyway, each to their own. If you are going to abuse your winch by extensive powering out then don't buy plasma / synthetic cause your winch will be stuffed before you get good use out of it.

Just on abrasion resistance of Amsteel Blue - it is excellent. It also comes with a 10 ft abrasion sleeve that slides up and down the rope so it can be positioned where needed. The rope is a lot tougher than people give it credit for.

Hello Rosco

Wear on a steel rope occurs under load while bending around pulleys and drums . The tighter the corners the greater the wear , and the wear is from the inside out . Trying to inspect for significant wear by looking for broken strands on the outside is futile because strength is already greatly decreased before the first outer strand breaks . Go for the stainless rope because it will last longer . Count winch cycles . Because you have a good reserve of strength in your cable you should be able to use it until you see the first signs of deterioration [ flattening of the cable or broken strands ] . Discard the cable and life your next cable at half the cycles . Although this procedure will increase your safety levels the normal drills providing for a sudden failure must still apply .

Hi Rosco
The choice you make will depend on a number of factors.
Some infor for you to help in your choice.
SS this wire will not corrode but work hardens and breaks
Galv wire will last a long time and will not create problems for you under normal use. 8.3 mm for 9000lb winch 10mm for 10000 lb and up
Both wires need to be layed up on the drum even and tight, the main damage done to wire is when they cross over under load and crush, this will not break the wire if the wire is rewound after each use.
Synthetic rope either 8 or 10 mm either will be stronger than wire the choice is what length of rope you would like on the winch.
Benifits are much lighter and easier to handle a little safer as there is no recoil from the rope,
Against; It needs to be kept really tightly spooled up or you can get coil binding
aand it needs to be kept clean as grip in the braids tend to chafe the fibres.
I have used both in competition without prolems. It is now compolsory to use rope in comps.
My recomendation is for normal use use wire as you will be able to buy 3 wires for the cost of the rope. Buy your wire from a wire rope merchant it is cheaper.
Always use a winch blanket with wire.
If you choose to go the sythetic way it is a good choice, a little safer needs more care but lighter and far more expensive.
The life of either depends on the care you give them
Hope this helps you
Ray

Rubbish synthetic is more expensive!. You can get 40 meters of Amsteel Blue delivered from the USA for under $200. That is less than you pay for gal wire here. I bought mine from www.okoffroad.com and sold my gal wire (was new) for more than I paid for the synthetic rope.

Hi Rosco
Sorry I missed this bit
Synthetic ropes do not like heat so it is not recommended that it be used on winches with internal brakes

That is only a problem if you are powering out for extended periods - which is not the way brake in drum winches are intended to be used. The brake is there to hold the vehicle. The power out function is just there to release tension prior to free-spooling.

Ok,
So I am giving info based on my experience and not knowing the intended use that Rosco will put his truck to.
There are a number of cheaper synthetic ropes on the market and I have used some and they do not stand up to severe use.
Wire ropes in NZ are about $ 130 for 45 metres
Synthetic between $400 - $600

I apologise Ray if you took offence to my post – wasn’t meant as a criticism.

I agree that synthetic rope over here is priced anywhere from $400 to $600. My point was that you can buy the same stuff from the USA for much less. We get severly ripped off here because it is ‘synthetic rope’

As for cheaper rope being inferior – don’t know about that. However, if you were referring to Amsteel Blue as an inferior rope then you are mistaken. It is widely used in the USA. It was developed by Samson Rope Technologies for offshore rigging applications and is UV safe and abrasion resistant. There are heaps of reviews and user testimonials on the net – which can be taken however which way you want. I am satisfied that Amsteel Blue is up to the job, not only from my research into it but from the use I have given it.

When it comes to synthetics, I don’t see much difference between the majors ie. Dynamica, Amsteel, Bronze, Plasma etc. This is what I have gleened from the research I did before I purchased mine.

As for the price of gal cable. ARB will charge you about $300 - $350 for a replacement cable – this is what I was referring to in saying you can replace a new wire cable with Amsteel and come out in front in $$ terms.

Anyway, don’t want to start an argument and apologise if I sounded abrupt in my initial follow up – wasn’t meant that way.

All that really matters is that each is happy with their choices – and satisfied they didn’t pay too much for what they get. Gotta love the net for getting good prices on 4wd accessories offshore. It’s a shame that we can’t get decent competition here to get prices down.

I am actually speaking with Samson Rope Technologies to explore the potential of importing Amsteel Blue and distributing it to the 4wd sector. We can pay retail from the USA (which we wouldn’t do obviously) and still undercut the current ‘synthetic rope’ market here by at least $150, inclusive of import and shipping costs. Accessories for the rope like aluminium hawses etc can be sourced and sold at a profit for about 50% of the current prices here. There is actually a guy on eBay who sells small quantities of Amsteel Blue for around the $500 mark – he is making a tidy profit from his direct purchases from the likes of okoffroad.com.

Hi Moggs.
No Offence taken. Thanks for your reply.
ARB here also think their wire is gold plated.
That is why I purchase from wire rope suppliers.
I have not tried the rope you are reffering to so I can not comment, ( but would be interested to see some info on it ) we have the other brands you mention plus a few more, and some of them do not measure up.
The original synthetic rope was made in Norway for the north sea trawlers I believe, and as you say some of the American rigging companies are also manufacturing similar products.
One of the competition trucks has just got on to some racing yacht braided rope and is trying that, it is only 8 mm but 12000 kg BS and has a hard outter layer but is not easy to splice, The others and wire are easy to splice and or repair.
Our biggest problem here is pumice grit getting in to the core and speaking to some of the Outback Challenge chaps the sand arround Brokenhill also creates a wear problem.
With all this imput we should all end up with superior products.
In NZ if you do not want to pay silly prices we try and buy from the master distributors or from parrallel importers, but I appreciate that may be easier in a smaller ( geographicaly speaking ) country as we do not have such high frieght costs due to the greater distances involve
I will be over there for the OC in 2006
See You there
Ray.
