I Australia we do things a little different to you guys in the States, especially when it comes to heavy haulage, this is a trailer that I am in the process of building,

It is what we call a swing wing extendable, 5 rows of 8, (5 Axles with 8 wheels per axle set) with a 2 rows of 8 dolly 48 wheels and tyres in total plus spares
so far the drawings are close to being finished ready to be CNC cut, so while waiting for things to happen, I was thinking of a load for it, and what better than a
big lump of iron for the back, and having a interest in all things big, I decided to scratch build a cat 657 twin engine scraper, of course it is the biggest they make
Problem there is only 6 in Australia according to Cat here, all in mine jobs, so what to do, ......... how about up scale from a die cast
I started with the front tractor and this is where I am after 2 days roughin it in to get the shapes right, still a long long way to go
here are some pics
Part I have started with

Total length when finished will be almost 1100mm (43inches) of just the machine, with 2 full sheets of plastic to chop up

Little more work done, started on the cab, will be happy when this is done, then I can start on the scraper connection, so as it sits, most has been roughed in, ready for finishing when all the major components are finished

Thanks Ben as for engines .... No would have to scratch a C18 and a C15
The machine does have engine covers so I do think I will be necessary because of the size I really want to keep the weight down with that in mind the weight will be in the rims and tyres as these measure 160mmx62mm (61/2 x 21/2") and being resin..... Then add 2 resin engines on top of that
The fulcrum point of the trailer may struggle with it when the scraper is loaded on this trailer in scale it will have less than 1/4" spare

Impressive is a small word!! . The amount of detail you could build into a model this size is mind boggling.

Respect . Dave.

This is a very interesting project and such a large scale to.  It certainly will be quite a weight when its finished.  Maybe think about making the fulcrum pivot point out of metal?  Just a thought.  Good luck with the rest of the project and keep us posted on progress.
