Rated Shackles
Submitted by C.P on Sat, 2016-03-12 10:11
Guys, whats the deal with rated shackles?
Appearently I've been living under a rock and only recently heard this is law
Do all the attachments have to have rated shackles?
- trailer chains to the vehicle, safety chain from trailer to boat, hook from winch strap to boat
Also how does the rating relate to the weight of the boat?
Does a 400 KG boat need 400 KG shackles?

Interesting one.
Yes there is load rated shackles, but why use them when the chains on the trailer aren't load rated!!
That being said, I have seen some shackles used on trailers and anchors, that I wouldn't even put on my key ring for my car keys!

chains are supposed to be rated aswell
Try licensing a trailer with out rated chains .the ones that i laugh at are those that use stainless clips , like there really going to hold if your trailer comes loose

Maybe I'm blind, but
i have never in my life, seen load rated chains on any trailer.

Only an issue as scott said

few years ago the new trailer
few years ago the new trailer chain regulations came in stating that all new trailers have the stamped load rated chain (does not apply to previously built trailers)
check with DOT if you need the dates.
On rated D-shackles
Use then anyway....why wouldn't you. even if the chain is not rated you don't want to put any old d-shackle on and have it potentially break even before the non-rated chain.
If your trailer comes off the ball you will wish you had them on there.

As long as the chains are
As long as the chains are certified and the welds to drawbar have had an X-ray.
Does anyone know where the love of god goes, when the waves turn the minutes to hours?

Why would you Ultra sonic
Why would you Ultra sonic test a fillet weld to a draw bar? That not what that testing is for. You could get a mag particle test done and that would suffice. I agree with using rated shackles but no point welding on rated chain as it's usually hi carbon content and would more than likely snap like a carrot with any impact.

Nailed it bud
Proper load rated chains need to be high tensile 880 (hercalloy/H8) steel.
It can't be welded due to high carbon content, and if you did, the heat would alter its strength anyway. Plus, it would completely rust out in about 18 months!

If we're being pedantic about
If we're being pedantic about metallurgy, you could apply both a pre and post-weld heat treatment to mitigate any issues due to high carbon content steel. This would maintain material tensile strength, and minimise the propensity to rust abnormally fast - particularly if you painted or applied a galvanising rod after welding.

So ya got an oven or a heat blanket to do all that shite. Why would you bother.

Try claiming insurance with
Try claiming insurance with out them if your car is separated from trailer . From memory chain has to be AS4177 and ten 10 mm is rated to 2500 kg.
X- Ray of the welds mmmmm not so sure about that, visual inspection most certainly but x-ray I don't think so.
Just took my trailer over for inspection as it ws only rated at 999kg after a rebuild and upgrades to 1999 kg.
it has been know that the "Heavies" conduct random checks on boats and boat trailers. Over and the boat has stay on the side of the road, not good if you are outside the Overlander were they where conducting the weighing.

The silly thing is that if
The silly thing is that if your running a 3.5t trailer the 3.5t+ shackles do not fit through the certified chain or most vehicle shackle mounts so it works out costly as the only way around it is to use hammer locks.

You will
only need shackles that are rated for 1.75 tonne if you are using two chains, the last couple of trailers I have seen didn't weld the chains on, one had hammerlock fittings joining the chains to the trailer and the other had put a piece of flat through the end links and then welded the flat to the trailer.
After rereading the relevant document it appears that my above comment re the load rating of shackles is wrong it does appear that each chain and shackle must carry the rated load.

Thanks
Thanks for the feedback
So its just the connection of the trailer chains to the vehicle that need rated shackles - is that correct?

technically how you hold your
technically how you hold your load (boat) on a trailer is your business although open to interpretation to traffic police/ main roads if obviously not secured correctly.
Really just has to be able to withstand a certain G force in certain directions. will be able to google it im sure.
new regs came into WA about 1 year ago about load on trailers .....ropes etc not permitted. yep you are not allowed to take a load of greenwaste to the tip without approved webbing or rachit tiedowns.

Guys, my thoughts if you
Guys, my thoughts if you want to comply.
Rated lifting lugs welded to the trailer, SWL stamped, NDT as required to AS 1554. Chains connect to lugs via hammer locks and rated shackles, noting that each shackle will need to meet the full load as will the lugs.
