looks like the spider on the flat top is a normal spider with a spacer on the outside ?

My Memories of those single tyre Silly wheel pusher Axles, Is..
In the early 70's when Triaxle trailers were allowed People started fitting them to existing Trailers to get the Extra Weight. .By the Late 70's The Govt mandated they had use Load sharing Suspension(As well as Brakes), Because as Xspannerman said a lot of them had Airbags & blokes could Manipulate the old split weigh Weighbridges with them..

But Don't mind being Corrected..

Hard to imagine now Paul, but in the 60's and early 70's the dolly steer axle wasn't permitted brakes.
Not sure if that applied to tandem dollies but was certainly the case with single axle jobs which were pretty common back then.
I'm still amazed when thinking back to the petrol KL Bedfords of Luya Julius with 1-sugar bin on the truck and towing a short dog with 2-sugar bins. Only brakes on the whole show were the pathetic vacuum/hydraulics on the 7t Bedford and 7" vacuum mechanical on the rear axle of the dog.
28 ton gross too.

Thanks XSPANRMAN, that's the one I saw on FB, fitted to a flat top trailer.
Think it was an ongoing push to get more payload within the regulations of the
day, at minimum cost. Tried on prime movers and trailers in differing ways.
Quite a number of bogie trailers extended and converted to tri-axles late 1970's.
Better set up, as load share suspension and brakes. Just from memory, Paul.

Seed I dont think the tippers shown were ever bogies as the mud guard is full length and it looks to me like these were built this way

Either way it is all very interesting to me and amazing how much of this stuff we have forgotten already

Jeffo, I cn honestly say I have never seen a single axle dolly with out brakes, mind you I wouldn't of worried about looking unless I had a reason to

Hi,

is this another one?

It was posted up in Overlanders Old Photos a day or so after the picture that started this thread, www.hcvc.com.au/forum/OldTruck/16820-ove...tos?start=870#226433

Jeffo, Dad had a Similar Setup.
Only His was an Inter AB160 tipper towing a 16foot Dog Trailer Carting Grain. Trailer had Vacuum over Hydraulic Brakes on the back axle only. No Brakes on the Dolly, From memory the axle in the Dolly was the back axle out of an Old Blitz with axles & centre removed. we were still using it up until the mid 80's..
