Totally agree....don’t hear of any trailer becoming uncoupled expect when in a major accident which the shackle isn’t going to help.
I was more pointing out to others that the suggested minimum doesn’t require a shackle rated to more than the van.

Isn't that why twin chains are supposed to be crossed, so they catch the drawbar if it comes off the ball?
Hi,
Yep, it also alleviates over tightening the chain if you Jack knife the trailer.
Cheers
Yes I’m theory but you might notice that the connect point of the chains on some trailers doesn’t help even when crossed as won’t catch the trailer.
At 80km/hr steel chain on steel draw bar and trailer draw bar flopping around, god chance it will slip off
I teach my worker to cross chains but also make sure they are short enough to keep the trailer off the road, but not restricting turning. Our trailer/car needs to go over weigh bridge before driving through the gate.
Searching, I found pdfs for state government requirements which relate the shackle rating to the rating of the chains. Basically, the shackle must be rated at least as highly as the chain.
Are the trailer regulations actually retrospective ?
I just checked my trailer with VicRoads portal to make sure its paid up and I see its made in 1980 , No such thing as breakaway brakes & rated chains back them.
At least my brakes are up to spec , but I just have Bunnings gal chain and unrated shackles.
Mods are coming along slowly. Im working through the lurgy .

I'll have to take a couple of spare wheels incase the front tyres on the thing Im collecting do not hold air, since I strap down the front with the binding strap around the outside of the tyre.
