Do u know what an A trailer is. It’s. 20 foot trailer , why do you think you know every thing? Them pics are 2 b trailers which = 4 A trailers…
You obviously haven’t got a clue about the difference between an A train v a B train.
An A train means two or more full sized semi trailers linked by dollies.Thereby each imposes no load on the lead trailer.Unlike a B.
Ok, so under PBS, A trains are not permitted in nsw… they run on outback I assure you a quad B is more then 130t … biggest allowed in NSW … is super B … at max weight … you need to grasp, the different legislative powers in each territories and states here in Australia …
As for not having a clue, that picture I showed you was two B trailers on a quad trailer …
Where as and A/B would of been a 20ft and a 40 ft…
Really shows you are clueless , when you confuse a road train with a B double trailers which as you can see, has 4 axles and a 5th wheel …
Must so frustrating, thinking you know it all when, in reality you are confusing A trains with normal road use trucks… road trains are not allowed on Sydney roads!!!
What has Sydney got to do with it.
A B lead trailer with 4 axles can’t possibly have the weight capacity of a triaxle lead trailer and a two, let alone 3, axle dolly.The argument isn’t about stupid local laws it’s about the fact that 3 axles + 2 = more axles than 4 and an A train obviously allows two or three full length load decks because it doesn’t need a fifth wheel and its turning clearance stuck on the back of each lead trailer and you’re going to need at least 5 axles on the lead trailer to compensate for the missing dolly and it’s axles.
Clueless indeed.

Yeah, a big heap of intelligence.
When the good Lord was handing out brains, you thought he said pains, and asked for the minimum.
A tad harsh mate, am I missing something is an A trailer longer than a B trailer and can carry more weight.
I’m sure the expert will be along later to let us know, so intelligent he thinks a dolly is a better trailer for weight bearing load than a quad axle trailer … what he doesn’t Realise is, a quad can carry more weight than a dolly.

Yes you’ve missed the fact that an A lead trailer has a full length load deck because you don’t need to drop a semi trailer onto the back of it.
You also seem to have missed the tri axle bogey of the lead trailer sitting in front of the two or even three axle dolly.My maths says that 5 or 6 axles v 4.
Good luck with trying to turn a 5 or 6 axle semi trailer.
B trains like close coupled drawbar outfits are just trying to reinvent the wheel and failing laughably.

Well, to be honest, I really can’t comment, I will await the expert to let you know… can ask me I only live and work in Australia like you … our resident expert will be along soon to let us know we are wrong.
But in reality, 7 states get together and make it up as they go along …
Did you know, the check points along the M1 , Hume highway, New England etc … are false,I mean who would make up a silly rule that all vehicles over 8t, would have to either divert or return to highway ….
Will we be shot down again?? Lol

Or for that matter the fact that two drive axles means less axle weight imposed on the road and more traction and less stress on driveline components.
Kind of irrelevant though in the UK apart from on specialist work, heavy haulage, forestry etc. A 6x4 is more expensive to buy, uses more fuel and requires more maintenance. If there was any advantage to using them on general work then everyone would be doing it.

The discussion started over the best configuration for an LHV.My case being that an NZ type 8x4 rigid pulling a 5 or even 6 axle A frame drawbar trailer provides the best return on investment without smashing the roads and eating diffs, half shafts and hubs.
Although a typical Ozzie A double or triple is the next best thing if anyone really wants to go large or go home.
For similar reasons as to why the NZ idea beats the typical dumbed down UK close coupled drawbar outfit.Train weight beats combination weight and two 7.5t drive axles is more road friendly and provides more tractive effort than one 10t + drive axle.
IE an efficient cost effective road transport industry which the rail freight interests and their government cronies would never accept here.

Again you are really showing how clueless you are…. An A trailer has a full body so does a B trailer ie super B … it has the 5th wheel so is like a second unit pulling the full loaded trailer maybe re look at the photos …
I will try to explain for last time, my brick wall has got it.
An A trailer is a triple axle, with 20 ft sliding … (if the A doesn’t slide, the trailer will never be able to be used) very similar to a retractable skel. And the B lead trailer is longer than A
A dolly is a double axle 5th wheel connected via pin …
A super B is a 4 axle exactly like an A trailer. However, longer that an A trailer … thus Carrie’s a 40ft container at full load … thus, making the A trailer 20ft shorter and less weight load bearing.
Now of course, we all know you have been driving these all here in Australia.
For the record the turn of the super B is easier than the dolly, you know why it’s a couple of metres shorter and are steering axles.
I actually don’t know whether to laugh at you or feel sorry for you with your pure arrogance of lack of knowledge at Australian vehicles.

Clueless indeed.
You have shown how clues you are a quad axle ie super B has just that, because it is 4 axles and has a 5th. Giving more reliability than a dolly just like being pulled by a truck … of course all thes big companies who earn millions and millions … will read this and say oh sugar, we won’t buy them because carry fast says er are wrong you indeed need to get a reality check with your I’ll informeed knowledge.
Carryfast, you are aware, a road train is different to an A double or B double or super B double right ?

It makes learning about new & different systems really difficult when that Igrt 4king C**t CF continuously spoils a thread with word diarrhea.
Good luck with crying foul to the mods just for suggesting that an outfit based on gross train weights beats one based on gross combination weights.
Or for that matter the fact that two drive axles means less axle weight imposed on the road and more traction and less stress on driveline components.

What do you mean by A trailer.There is no such thing as an A trailer.
An ‘A’ train is just made up of standard length trailers coupled with a dolly/ies. So an A double or triple means two or 3 standard trailers that means two or three full length 45ft ? load decks.It also means 11 or 16 axles total including the unit with tandem let alone triaxle dollies.
Remind me what is the load deck length of a B lead trailer which by definition has to include the space for the fifth wheel and turning clearance for the connected trailer.
How is the 4 axles of a B lead trailer supposedly better than the 5 or 6 axles of a tri axle and a dolly ?.Which by definition means that you’re short of at least one axle every time you connect trailers in the B configuration.
As for turning I said the EQUIVALENT 5 or 6 axle B lead,
v a triaxle trailer and a two or three axle dolly and its two points of articulation,
as opposed to just the one point of artic of the B.
Also bearing in mind that the load distribution of a trailer affects the axle weight of the lead in the B configuration.
Just like the load distribution of a close coupled drawbar trailer affects the axle weights of its prime mover.
Unlike the A frame configuration IE train weight v combination weight.
You’re avin a larf.

You are clueless, an A Double in Australia is 1 20 ft and B trailer ft stop confusing an A double with A road train … how clueless are you … a B double is longer and bigger than an A double… plus Road trains are not permitted in cities … trucks are not as big in NS as over here in Australia … so go back and google your incorrect facts yet again.

You are clueless, an A trailer is a 20ft trailer on a sliding 40ft trailer … when driving along with the A trailer it is drawn forward over drive axles to stop chassis twisting … A trailer on road trains are different… come to Australia and quote A trailer show how clueless you are.
Picture one
Is a combination of A trialer and B trailer
Picture 2 is a combination of 2 B trailers on a dolly config
Picture 3 is a super B with both trailers have a 5 th wheel enabling more weight than a dolly configuration
Picture 4 is a road train which consist of A trailer and B trains and are not approved to be used on PBS areas… ie only allowed to be used in out back or on open roads only ….
They are also starting to use super B double trailers…
I suggest you research. You think there is no such thing as an A trailer
As the Lindsay picture proves you are talking nonsense yet again
Now accept you are clueless… or are half the haulage firms in Australia lying.
However, we are now trialing B triples, consisting of two A trailers and a B trailer as below …
As you can see, they are both on triple axle fixed, reefers slide, but regardless … they are still 20ft x 2 and a 45 48ft to rear eventually, they will be 3 45 or 48 trailers on quad axles all with steering wheels ….

I don’t get your reference to A trailers.
What you’re showing is two obviously compromised B configuration trailers and a trailer dropped on the second B lead and 12 axles total.
Compare that with an A triple.
Three full sized Tri axle trailers coupled with two tandem dollies.Thats 16 axles your heap is short of load deck length on two of its three trailers and short of 4 axles.Let one if the A triple is coupled using Tri axle dollies.

Seriously, are you that thick an A trailer is just a 20ft on a sliding 40ft trailer …
They are not Dollie’s …,they are triple axle on 5th wheels
Are you seriously, that ignorant, when you are clueless, you go off on a tangen, to try and make yourself look right
You harp on about A train … no,such thing .
It’s a road train … which pulls an A trailer or B trailer via a dolly
An A triple as you call it is not what a Road train is … Dollie’s do not bare weight like a super b double …
Look at the picture, see the fifth wheel behind fixed 20ft curtain sided that is an A trailer for the double … which also bares more weight loading capacity that a dolly … hence they are now using super B trailers with 4 axles and A triple would be 3 20ft trailer not 2 20ft and a 45 ft… carryfast you look like a upper you are wrong … nothing is compromised in that photo it is 2 A trailer and. A B trail hence a triple double.
