Soft Shackles Group buy. Expressions of interest

This is the vid I mentioned earlier in the thread

I wonder if they have a SWL
If it does't have that then you may be held accountable when the come off and someone gets hurt

Not all that much gear in a recovery has an SWL, most of the gear will have a B.S. and some will have nothing as there are no Aust Standards to rate against.
The SWL of a shackle is not rated for the purpose it is being used IE we are using a device designed and rated for a totally different application that will do the job we want.
99% of users won't know how to care for the gear or derate the shackle SWL depending on Sling Load Angles etc anyway...

These loop systems have been used in a D-LOOP on compound bows for years on a smaller scale and are bullet proof. On a larger scale of 10 or 12mm they will hold up to the pulling forces I would expect but not sure in a recovery snatch situation.

They have their place in the market place for sure

The 'name' brand soft shackles usually have a rating some as SWL but most as BS.
As a guide the expected rating is the rope rating times 4 (the shackle is doubled over twice IE 4 strands) divided by the knot strength divided by the safety factor
12mm Dyneema will be 13 tons X 4 equals 50 tons (close enough)
50 tons with a button knot will be about 70% so 35 tons
35 tons with a safety factor of 3 means around 12 tons, 28,000 lbs or 12,000 Kg.

Rough rule of thumb is just treat the Soft Shackle BS as the same as the equivalent Dyneema/Spectra/Amsteel rope BS and you will have heaps of safety factor

Sorry for the hijack, Kallen.
In the vid they were using the soft
shackles on the steel shackle
so were creating another
point of failure. Yes, they are
simple to use but I can't see
the advantage as I use a rolled
up magazine to stop any straps
locking into each other when joined.
Rounding out any recovery
points to accommodate the
soft shackle reduces their
rating and also the amount
of metal to metal contact
if you have to use a steel shackle.

i daunt think you should under ester mate them they are made from Ultra-high-molecular-weight polyethylene (in block form it is 15 times more resistant to abrasion than carbon steel)

It has joust gotten cheap enough for the Joe public.

They are used by ships to moor, when moored the rope gets massif shocks, from the ship bouncing of the side of the dock and then shocking the rope.

It is also used by climbers on there nocks witch get wedged in cracks of rooks for the safety line, when they fall all the shock hits the (Ultra-high-molecular-weight polyethylene)

I hope they have a place in 4x4 recovery , it'll stop stupid accidents like the 17yr old kid in NSW from happening,
has anyone heard how he is going??

[Chubba]

Any word on the numbers Kallen?
Is the group buy on mate?

[threedogs]

and put my findings here

[Patrol-Guy]

Keen as. If you have never tried to cut 10mm dyneema then I can tell you it's bloody hard work! Not like cutting rope. Hard work.
