Hi,
Does anyone know what the side wind tolerance of a double deck box trailer is? 16ft tall, small wheels■■?
I’ve asked loads of people especially trainers and no one can give an answer.
There isn’t any official figures, and i hope it never happens.
If they came up with official figures drivers will just get fined for driving a vehicle in excessive wind.
Don’t know but I drove a Morrisons Decker from Wigan up to Bellshill in Scotland and back, for a few years in all weathers.
You’ll be surprised how much side wind they can take. I’ve been through Gretna an Carlisle with gusts of 70-80mph with my arse chewing the seat and gripping the wheel with white knuckles and it was ok.
You get knocked around a bit but they’re more stable than you’re brain says it should be!

Agreed. Those double and triple deck trailers have got a lot of weight to them, even empty. In strong winds I’d much rather be driving a 16’2 artic decker than, say, a 10’ tall curtain side van or 7.5 tonner.
Depends how it’s loaded.

Amen to that!
I’ve had 10 years on them and they seem more stable than you’d expect. Slow down if you don’t feel happy and use common sense. Keep the curtains fairly tight (FAIRLY!) - if too slack they act like a drum-skin and can bang you about a bit!
Try to keep the weight on the bottom deck near the step to keep the centre of gravity low - you might need to explain this concept to most forkies

Agree with that entirely. Never had a problem with them in high winds. As opposed to a Luton van over the Avonmouth bridge one time in a blow. There was one moment when I honestly thought I was going over the side.

I agree with what the other people have said, I’ve always found them to be the best trailers to be pulling in high winds.
Deckers with those little wheels on are much more stable than one the same height on big wheels, even when its not windy!
i was pullin 16"6 deckers for comet, theyre sound you will be surprised they are sturdy with them small wheels good luck with it
I always find they are sturdy, just wondered if anyone had an official wind speed figure.

As soon as Sally traffic declares it shut to high sided vehicles 
A transit van is high sided as opposed to a TVR.
It’s a question I’ve pondered about myself also.
They had some tandems on small wheels at Woolies and you only have to look at them for them to go over. Probably, mostly down to loading really though having said that were never a nice drive empty.
It’s mostly down to the load being lower than the fifth wheel though rather than the wheel size particularly, those glass trailers are very stable in the same way.
Deckers, with or without wind are dangerous if they are not loaded properly.
I once watched a trailer being loaded in drop order and most of the weight was on the top deck. When I pointed this out I was told to mind my own business and do what I was paid to do, DRIVE.
On this occasion I was not under this particular trailer,but I told the management I would not take a decker out that I had not supervised the loading of.
As it happens I was never put in that position, but what would have happened if I had have been 
In high winds with a trailer on in a lot of cases if you look through your mirrors the trailer is bolt upright and it’s the cab that’s been blown. Similar to cornering, the cab leans but the trailer is upright…This is of course assuming that you are driving at an acceptable speed for cornering.
