Check the park brakes have been applied, also question if these are runners or are they non runners going for repair or scrap…if non runners its possible (even if the height of stupidity, and yes this was suggested recently by someone 
) that the brakes have been wound off to allow the units to be winched or pushed up onto the bed.
Hopefully its a proper truck or plant transporter with high load capacity anchorage points in the deck itself.
Obviously the most forces will be exerted under any hard braking you might encounter, but make sure there’s adequate restraints pulling forwards too…common sense applies here, yes i’ve seen 4 x ratchet straps applied all pulling a car the same (wrong) way before 
and this from a bloke without a minute to live who’d been doing the job (badly) for 20 years plus, and yes that resulted in lots of damage once he got moving when the car in question jammed up between the prime mover and cars on the trailer on a turn.
Thanks for all the info and advice.
When i got to the job the “ordinary” flat bed that was described to me as exactly like a box trailor but with out the box and morphed into a 18.5m extendable swan necked trailor (sorry not sure of the correct term) and the 2 units had chaned into a single decker bus.
I wont bore everyone with the tale of woe that ensued ill only say that someone came up to take over at the delivery point to bring the 2 units back.
Hence arises the question,
The guy that cane up to take over said that the chains should be hooked into the wheel hubs at either 3 or 9 oclock. His reasoning was that if the vehicle moved and the chains were at 12 or 6 oclock the chain could go slack. The guy at the destination said no it should be 12 or 6 and the vehicle couldnt move because it was being held by its oppersit number pulling the other way. who was right and why.
I admire your…
Determination and willingness to give it a shot.
From the technical points you’ve raised, everyone will tell you different. Over time, your own experiences will give you confidence.

Just to be clear:
You had a low-loader trailer, extended out to 18.5m, with a single bus in the well of the trailer?
The bus wheels were chained to the trailer?

Yes but the question arose at the other end when they put two units on the trailor and were chaining them down
From a physics point of view he’s right, if the chains pulling it back let go it doesn’t matter where the front chains are attached. Is there really a chance of the wheel slipping without the loaded vehicle moving? That’s when the 3 and 9 (or more specifically half past 4 and half past 7) would be beneficial.
I’ve no idea if attaching to the wheels at all is correct.

So, now there is a trailer, extended to 18.5m, with two units loaded in the well?
(You can see why I am asking, I guess…)
But you are concerned about where to place chains on unit wheels?
You are saying there is one chain hooked into each of the wheels of the unit?
Steel wheels, with vent holes in them?
The chains on each wheel pull opposite directions?
And you want to know which is the best hole to choose? (Oh my! 
)
I have never read so much in one post me thinks is it a wind up ,its got to be to see who comes up with the most nontechnical. Tractors were only ever roped large and small on 40 foot single axel trailers, no head board ,before straps every come in never ever heard of anyone losing any.in the 1970/80,s so nothing new in transporting tractors.
YES i know it was years ago ,and standards have changed for the better ,but “what holes to put the chains through”■■? and its called PROFFESSIONAL DRIVERS. perhaps i should not read theses posts as retired

i have never done it or been shown
one experienced driver says 3 or 9 oclock
another experienced driver says 12 or 6 oclock
come to a forum to find out the correct way and get accused of winding everyone up real helpfull. I guess it doesnt matter as i wont be doing that job again.

The photo on the DVSA site shows a truck being “piggy-backed”.

The straps on the wheels seem to be at rather random positions.
So long as the wheels don`t rotate*, I doubt it matters in the real world.
Personally I would like to see each wheel strapped and the chassis chained.
Overkill? Only takes a wee bit longer
*Why/how would wheels rotate unless the unit is actually moving tonfro?
If the tyres were deflated and no weight was holding them firmly onto the bed?? Maybe, but doubtful IMHO.
And I still want to ask whether two units were being carried on an extended out trailer?
Low-loader or Step-frame?

the trailer was only extended on the way up with the bus. They closed it up before they put the two units on for the return journey,
trailor was like this but obviously not a model. jacksonsmodels.co.uk/wsi-tr … gJI8_D_BwE
the units were loaded so the rear wheels were on the front slope and the front axel of the second one was on the beaver tail ie after the trailor wheels

This incorrectly captioned picture is one of a series. In that series it is clear that this vehicle was piggybacking another of the company’s lorries and that a lot of this damage was caused when it broke free.

Sorry wrong picture, this below shows the one on top, the other picture is of another vehicle involved in the same incident.

In a word no they wont be
basicaly me beung an incompetent fool trying to take a trailor that was 1/3 longer than a standered length so the wheels were that much further back and expecting it to follow me around like a normal one.

De Rooy are a rather special case.
Some truly cleverly engineered specialist vehicles, very imaginatively designed for a purpose.
I don`t know about to-day, but the imagination was also present in…umm…other aspects… of their truck operations too.
All part of the same family involved in various motorsports notably the Dakar rally.
