This is a 28ft with a 53ft B train a lot more stable than an A frame

My 6 wheel rigid (tag axle) is plated at 18,200kg on 2 axles…

No it isn’t 
For a start, a 3 axle rigid doesn’t actually specify anywhere on the plate what the MGW is with the tag axle lifted, it only specifies the MGW with all the axles on the ground and the maximum permitted weight on each individual axle.
I assume what you mean is that the maximum weights of the two non lift axles add up to more than 18000kg, but (as I understand it) construction and use regulations forbid a 2 axle rigid being over 18000kg so if you load them both up to their maximum weight you’ll need to put your tag down to stay legal.
The reason the axle weights usually add up to more than the MGW is to allow some flexibility on where the load is positioned.
If you add up the maximum weights of all three axles I would expect it will come to a fair bit more than the MGW of the vehicle as a whole too.

It is an interesting concept, both the big yank and the Denby machine, they use similar designs except the box van has a sliding chassis to allow it to be unloaded while the Denby curtainsider appears that it can only be tipped from the sides.
Having not seen this in the flesh, only on the video, it was interesting at 27 seconds to watch the rearmost trailer to kick into the the nearside while the drivers view is obscured. Does it have a camera fitted to make sure the rear trailer isn’t going to wipe out a lampost?
Take it to Australia where it belongs, lets face it carries more so cuts rate everyone gets one so now you get same rate for fifty tonnes as you did for fourty four and dont say it has not happend before because it has.The driver will not get a fair rate thoe goovernment will want big hike in road tax the insurance will be sky high and can you imagine stuck behind one ,no thank take it to Australia our country is overcrowded and the roads are to small

Cutting the rate is what in the free market economy is called competitiveness.That yank outfit probably is’nt the answer because it’s not made to carry very heavy weights by looking at the idea of using the rear two axles of the first trailer to also carry the load of the second trailer.Whereas a decent drawbar outfit does’nt impose any loads between the trailer and the prime mover.An eight wheeler rigid and four or five axled A frame drag would allow some serious weights to be hauled but it would need long distance European work taken from the rail industry to really make it work economically.So there would’nt be any need to use them on Britain’s roads although the motorways here are’nt crowded at night.It would be up to the industry’s trade associations to put pressure on the government and insurers etc to make sure that those taxes and insurance rates would’nt stand in the way.If,that is, we truly are in a free market economy and not one which applies protectionist policies to some transport industries at the expense of others.
