If I attach my 2 Number 5 trailer chains to my Perentie, are the 2 pins used on the vehicle rated?
How can you tell a rated pin, if it's not powder coated yellow?
Should we pint our chain pins to make them "look" rated?????

Yet another facebook claim. Show me the appropriate legislation or rule.
The rule does not exist. There are various advisory documents around suggesting rated shackles should be used. These documents advise people of the availability. Realy when the appropriate legislation does come in, it will state a date or description of what vehicles these rules are applied to. It will also state the minimum rating for the application. It's no use using a .5t shackle on a 3t caravan.
Should I paint my pigtails yellow to signify they are rated?

You'll probably find the Perentie ones are rated.

Yep, I've never found or been shown legislation that requires rated shackles to be used. At work, we do use rated shackles on all trailers, but our policy states this is for 'best practice' and not a legal requirement.

This is as much as VicRoads has on the subject - there is no mention of what style of shackle is to be used to couple the trailer to the towbar, just some stuff about the safety chains - also worth noting is that the chains are not required to be rated, just capable of withstanding certain loadings which you can find for most chain - even non rated stuff. - https://www.vicroads.vic.gov.au/~/me...i24.ashx?la=en

All,this stuff about rated chains, shackles and vans being weighed all seems to be 'a friend of mine got his van weighed today' or 'a friend of mine got busted for not having rated shackles'. I've never actually heard from someone who have themselves been done for these things. A bit of an urban myth IMO.

I think you should go read VSB1 it says differently.

Happy for you to post a link - looks like VicRoads need to read it too.
