Not sure the type approval stuff says "chain". Basically over 750 you need a breakaway cable that when the hitch fails the handbrake applies then snaps and leave the trailer stationary on the motorway without showing brake lights for the car following to close to plough into.

For under 750 as you have no brakes it might roll back down a hill on the motorway which is REALLY bad so you have to attach your trailer with a secondary coupling device. So when the axle fails you drag it behind you digging a rut into the carriageway ;-)

I'm under the impression everything is supposed to be type approved. But I struggle to find chains with E mark. None of the unbraked I've ever bought has had a chain. One had a 3mm wire loop

So at 60mph ... On The motorway up hill ... Your 750kg trailer disconnects .. What force does the chain need to take?

How do I know the 3mm wire is strong enough?

I bought an ex demo SBS trailer last year as it has brakes and is a nice piece of kit but pricey compared to my old tub. On the downside it has sealed for life () bearings and relatively inaccessible brakes which I regard as a backward step for home maintenance when I just had to grease or easily replace the old style roller bearings on my previous trailer. I now need a large socket, length of scaffold pipe just to get the nut off to look at the brakes plus access to a press to replace the bearings !!

There's no wonder they get neglected.

But is a secondary coupling mandatory.
I didn't think it was & a 3 mm wire is surely just a breakaway?

Again yes it is.

I bought a second hand 1300kg gross weight braked trailer early this year with disconnected shot brakes.


Made sure the necessary was spent to overhaul the trailer to make road legal. Money well spent as VOSA are keen in my neck of the woods and will hand out a hefty fine without a second thought.


Better safe than sorry

Just been to check the type approval rules. Not sure the secondary coupling needs an E mark. The coupling does and secondary coupling is in the text before it so not 110% sure its not inferred to need an E.

However with regard to need... A secondary coupling is mandated on all unbraked trailers. This is a retrospective mandate so applies to all trailers.

The rule is it needs to be 'sturdy' and it needs to stop the hitch touching the ground.

The 3mm cable trailer was only rated to 350kg. it wasn't a breakaway as there were no brakes to apply.

Also discovered that braked up to 1500kg has choice of breakaway or secondary. Above 1500kg must be breakaway...

So I'd assume a secondary coupling should be able to take a load of 1500kg --> plus 60mph driving and a hill suddenly applied without breaking.

I think that might be the point ShinyShoe is making (badly!) - secondary couplings are more often than not unrated and it requires the driver to be intelligent enough to specify a suitable system.

Does the secondary rule apply to old trailers then ie do you need to retro fit to an old trailer my rib is on a very old trailer made when they didn't need I'd plates & such like
I've got a couple of big braked trailers & I'd kinda forgoten about the little rib trailer I guess a short chain on a carribeiner will do if you do need to retrofit secondary couplings?
