Not sure Patrick, I’ll drop him a line and ask.

Who said that Buzzer? Far as I’m concerned, keep on going!
The FTF didn’t left the works as a 8x4, it was modified by it’s current owner, looks the part though.
That one has been brought back to the UK recently Oily, the plan is to restore it to it’s former glory.

So…there are two pivot points ?
The unit has a semi trailer.
The scraper has a pivot point? The hydraulics have not been blocked to hold the pivot rigid it appears.
The rear dolly has no pivot? It is attached rigidly to the chassis of the scraper.
I would guess that would follow quite well but be a cow to reverse. Not that it would need to get on a bay at an RDC of course!
I’m not sure, but is there perhaps a pivot point on the rear dolly? There looks like a piston in front of the first wheel of the dolly too, the combination might allow it to become a rear steer.
As to reversing, your ‘cow’ comment is apt, you need a road train driver for that. 
The bloke who put it up, on an American site, answered a question about cornering by saying it followed very well.
Yes, I can see some sort of ram or tube from the front of the dolly, that is what you mean? It looks to me like the rear dolly is actually touching the scraper? That wouldn`t prevent it having some sort of steering ability though.
The weight is carried through the pivot just foreward of the first wheel on the dolly, there appears to be a connection to a towing eye under the axle of the scraper and, if there were 2 pistons pushing one side or the other around the pivot, that would work wouldn’t it?
I’ll try and track down the thread again and ask, but that site is not easy to navigate for a newbie. 
Hhmmm… 
If all the weight is in front of the rear bogie wheels, and there is a pivot point there? That seems very suspect to me.
I would have thought that the load would need to be very firmly attached to the rear bogie/dolly to stop it being levered up?
I am not stating this as facts, of course, just musing. If you can find out definitively that would be interesting.
Haven’t tracked it down yet but the weight is slightly aft of the 1st bogie wheel, not completely on it, but I admit I would prefer it to be nearer the middle, it is possible to see the slight depresion of that front axle.
Edit: Found it, for what it’s worth.
In answer to the question about cornering this was the first reply:
Yes it does. A scraper on a dolly is one of the easiest things to bring around a corner. They are a pain in the ### to dolly up tho lots and lots of work involved in that setup. We used to have a massive set of ramps that we would set down behind the lead in order to load after dollying. It also took some fairly large chains to chain the can up, if you didn’t the hydraulics would bleed off during transit and could cause a wreck.
2nd reply, from the OP:
Yes. Handles like a dream. I really enjoyed hauling them like this rather than on the CA 9 axle.
3rd reply:
I have a couple old scraper dollies in my yard, the hands asked what they where and if we could go back to hauling scrapers. The answer from my dad and I was a resounding hell no unless there was nothing else to haul. At one point we had a sixteen wheel basket which wasn’t near as much work but it didn’t pull as good.
If you can unravel all that, good luck. The picture was taken in 1988. The post from 2015 at the start of a long thread, so may not be easy to get any more info.

If you are wondering how difficult it was to get back to that picture,
it was in the Big Load thread,
in the Heavy Haul Trucking Forum, which was within
The Flatbed Trucking Forum, which was within
The Tricks of the Trade - Occupation Specific Discussion section of
The Forum Section.
FFS, and we thought this place was difficult. 
Oh, and it is in fact an American Forum, not as I thought a Canadian one, but,
It has a Canadian Section (in which I first arrived) within an international section.

I`ve given you a “thumbs up”, but maybe a medal is more deserved.
Thanks for the effort. 
It is true I am exhausted, I feel as if I pulled the bloody thing myself. As if that wasn’t enough I have just finished a search for the details and a picture of a fomer PM of the Netherlands who has just committed suicide with his wife, both holding hands and both 93 years old.
I expressed support because some extreme Christians expressed disapproval and it didn’t help that the photo purporting to be the man was in fact the current PM, Mark Rutte who is obviously much younger.
I managed to correct the situation by finding a picture of Rutte with Agts taken in 2011 to set the record straight.
I hope any posts did not contain a spelling error? If so a wholly logically correct, and well sourced argument will be slagged off in an instant!
Yes, they really do things differently over there mate. Interesting pic though, cheers for posting.
Here’s some more from my trip to the US, spotted these two on the main road just outside the Flying J truckstop in Carlisle, PA.
There appears to be a pronounced “positive” bend on the 2nd trailer pictured. designed so it straightens out when loaded rather than sag down. I can see the thinking behind that but In can`t say I have noticed it on UK or Euro trailers. Do we do that?
Great to see you have made it, Spardo. Your input is valued and enlightening.
Re the scraper, it appears to me to be solidly secured to the dolly. A 6370 is only about 50’ long, so no real need for a steerable dolly. At approximately 50 tonne, it’s not a particularly big move, considered in the context of USA or Australian movements. Its not likely to be crossing the Brooklyn or Habour bridges.
The Yanks fully embrace the KISS principle, so unlikely to be considering steerable jinkers, when not absolutely necessary.

So do you think that the steering rams of the scraper have been locked, or, as Franglais suggests, 2 pivot points?
If the dolly is secured rigidly to the scraper that puts a hellova lot of weight on it and I would have thought the point of contact would have been smack in the middle of the 2 axles. You can see how it is slightly depressed at the front.
Incidentally, back in 1960 ish before I had a driving licence, I worked as a chainman (surveyers’ assistant) on the building of the Stapleford and Sandiacre by-pass on the A 52 between Nottingham and Derby.
There were several scrapers used, single engined Cats and double engined Euclids, similar to the Cat in the photo. One of the Euclids was parked at the bottom of the bank they were landscaping with the front turned towards the bank ready to re-start after a break at the tea wagon. When the driver re-started the engine, he slammed it into gear and, as the 2 front wheels tried to climb the bank the whole thing flipped completely upside down in an instant. The driver in his steel cab was ok, but I spilt my tea getting out of the way.
