There is around 25 of them going out of Bris between Easter and Xmas.
I used to escort them out of Bris for Main Roads but got sick of the night work.
Will try to find a photo of a 600t one we took out a few years back.

Was that the one that went up the Toowoomba Range with about 12 prime movers.Now that was a big mother.

Ok, after a very long 4 hours in the freezing cold, I managed to get some more pics of it on the move. The quality isn't brilliant, but with no flash, and frozen hands, it was the best I could do.

The things I do for you people.........

Are you hooking on in the last photo on the first page?

Yea, thought I might give it a go.

Might need to drop it into low range to get some traction thou...

so, how do they maintain 50?
do the trucks just pick a gear and set the cruise control?
do they have to synch gear changes?

From what I understand, the lead truck calls the shots. Gear changes, braking etc.

Mind you, last night, they were stopped for a bit, and when they started off again, the last 2 trucks were out of sync with their changes. So, I guess that they know their trucks, and the output.

The other thing that was that as they moved off, the last 2 were pulled off the line by the ones in front before they brought the revs up. Makes me wonder what kind of power the front trucks had...

So what your telling us not only did the Mack at the front have to push the Volvo at the front, it had to pull the other two as well???

The Mack and the KW probably have an 18 speed main gearbox and a 4 speed joey box. I'm sure someone on here will know more.

Its not impossible that all four trucks have the same engines trannys and diffs,, (though not probable)

I would think the first two would do all the work,
the rears only needed on hills and for emergencies????
