Magazine snatch strap test - ARB letter

[ToNkA]

That is a load of crap Grimbo - As someone who does research/testing for a living you need to work on averages - so multiple samples would have been much better (at least 3 of each strap). Not only will testing multiple samples give you an overall average of when the strap will break, the range between the samples will give you an idea of the quality control/uniformity in the manufacturing process - which is what you are talking about.

I would much rather buy a strap that will fail at over the rated break load in 85% of samples that one which will break under all the time.

Studying statistics and experimental design for 5 years, you are spot on. The test was horribly flawed and the results are not true representations of the straps. Was a good idea just not executed very well.

[CRUSHU]

sorry tonka, but i disagree, it may not be an accurate test of the average strength of the straps, but that is an accurate test of the strap that they bought. the same strap any one here could have bought. they specifically did not buy them direct from the manufacurer, so they wouldnt get "special" straps.

I'd like to know where they got this info from.

Throughout the whole 6 days of competition l only saw 1 snatch strap used and this was to tow us when we ran out of fuel 2km's out of packsadle.

I suppose you also saw all the other cometitiors on all the other stages at the same time too?

The OBC is a competition, and the aim of a competition is to beat the other competitors in time, personaly speaking, we passed plenty of people and plenty of people passed us during the stages, not one person in our group of 12 asked "could you give me a snatch mate" during the stage.

Everyone out there knew you have to be self sufficient, and when your on your own hooking up your snatch strap to a tree just aint gona get you out of the sh!t. When you got stuck, you winched, simple as that.

Perhaps we didnt get the survey sheet which asked about our equipment and recovery gear.

Guys for the two years we have been selling ARB snatch straps we have only ever had 1 returned for warranty and that was due to owner abuse not a fault of the strap and we usually sell on average 10 a month

[mud4b]

two years?

[Fathillbilly]

iI know for a fact that ARB was told about this problem (the stitching) over a year ago.

i was involved with the development of the "black snake snatch'em" and like any good venture you do some research, so the market leader was tested, and it failed!!!

it was also apply to a cyclic load test, which is a series of loads applied to the strap to see how it behaves after a certain number of "pulls", whether it retains it's elasticity, original dimensions, and strength.

it was found that the majority of straps are stuffed after 10 pulls, let a lone the 120 pulls (3 cycles of 40 pulls varying from 500lbs to the full 8000lbs) the a black snake can handle, and still retain it's genuine 20% stretch and 8000lbs SWL

[MUSS]

HEY FATHILLBILLY....where can i get me a black snake snatchem? i heard about em havent seen one yet?

[zookjedi]

faithability i believe you mean 8000kg not 8000lb else thats only good for zooks, if that

[Beastmavster]

so what do we do if we own one of these snatchems????? im almost scared to usem lmao

With the breaking strain still something like 3 times the weight of your 4by you're suffering from media-beat-up-itis.

The ARB product fialed because it did not meet it's claimed weights. That doesnt mean it's unsafe - they still rated soemthing like 8.5 Tons load and 9.5 Tons load from memory.....

used my ARB strap this weekend 2 times, didnt fail once, its old now, probably could do with replacing...

Black Snake sounds good, Stuey, wheres the goods????

We used one on a club trip last year it was a trial one, The only critisism of it was its length 6m I think from memory but seeing though it was a proto production ones would be longer.

Performed as you would expect what I liked about it is the Snake strap looks like it would handle being dunked a lot better due to being kinda sheathed in construction hard for mud to work into the fibres.

They are ( or were ) more expensive.

This Snake strap doesnt look more like a rope does it?
Like a bungy cord?

Yep that is the one, the production ones are 10 metres from memory.

Bruce, I know Cheezy has them, dunno who else though.

[RUFF]

Yeah ok a mate of mine won one of these last year at a short coarse event but im not sure if he has used it yet.

sorry tonka, but i disagree, it may not be an accurate test of the average strength of the straps, but that is an accurate test of the strap that they bought. the same strap any one here could have bought. they specifically did not buy them direct from the manufacurer, so they wouldnt get "special" straps.

Then what is to say that the one Strap they used in the test happened to be faulty/lower quality and therefore you believe all of them to be faulty.

Yes they used one off the shelve that anyone can buy, which they should; but replication and large sample sizes are the two key elements to a less flawed experiment. It would be worthwhile to see the variation within one brand of strap and the comparison of straps from each company.

If 5 or even 10 straps were tested from each company you would be able to see the trend of whether each company was producing straps that were similar in performance (this would give an idea of the construction process. If one brand of strap differed dramatically within the 10 cases (lets say a range from 65% to 100% in performance) and another brand of strap performed close to 85% in all 10 cases. You would favour the 85% strap as you can be certain that any strap from that company you take off the shelve will work to 85%.

The way they performed the test would not take into account the variance in one particular strap and strap 1 in the example above may test at 100% and be rated higer than strap 2. When infact if you went to buy strap 1 off the shelf you may be getting a strap with anything from 65% to 100% in performance.

yep that would be it, to tired and hung over but i think faithability is way beyond me

some ARB out lets do carry them but you pretty much have to ask for them as they are not pushing the sales of them over there own product

other wise call Jason direct on 0413023582

the black snake looks like a rubber coated rope.

it is made by running 1 continuous thread around and around 2 pins then it is rapped in abrasive resistant rubber, and cooked.

when it breaks it fluffs up like plasma rope with almost 0 recoil, as the rubber acts like a dampener

they are more expensive but you get what you pay for, and then some.

the only real down side is they are pretty stiff to start with and a little heavier (3kg over a strap type if i remember right) but after a few uses they do soften up.

i got the first one ever made to test, basically to try and ruin it.

so what do you do? you find a big tree that has fallen over loop the strap around it and drag it around all weekend, it would get stuck across the track every now and then and so you would try and snatch it out of the jam sometimes with no luck, then over rocks, through rivers, drive over it, turn a front wheel back and forward on it while on sharp shale (not good for tyres!!!!! ) i only used it once to get someone out, any so i gave it back and it was tested to see if it was weaker or what ever, and it ended up breaking at 16000Kg, they couldn't believe it, neither could i,
but hay that was the first black snake

the only damage i did to the strap was pull some of the rubber away from around the eye from tying it around the tree, but that was resolved in the second prototype

Ive got a Black Snake 8 tonne strap and its ten metres long,

awesome strap, made in aus, cost about $100 (i think)

[spazbot]

why didnt you boys test it for the mag aswell planb ?

I've got agree with CRUSHU on this one - the test they preformed to see how a strap that anyone one of us could go and buy performed.

The ARB they picked off the shelf didn't perform as advertised.

Now had the test been designed to check the quality control of the products, then by all means take a batch of 100 of each and test them all - but that wasn't the test - they weren't testing averages - I'm not going to buy 100 straps and test them all and then pick the best of the bunch....I'm going to walk into ARB as a trusted supplier, pick one off the shelf and use it.

For what its worht, in reality I've got the Bushranger strap that was a gift when I first for the Jeep - its performed perfectly everytime, and I was glad to see it up there in the testing. I've also got an ARB strap that I carry as a spare.

[RoldIT]

Agreed ...

[planb]

why didnt you boys test it for the mag aswell planb ?

i recieved it after the test was done.

we're testing it in the field soon
