You could mess up a bitumen yard on a hot day with one of those things..... We don't see them in Vic.. yet. Well, I haven't, but I'm not out and about a lot atm.Quote:

That's the same configuration I was using on my last forays into Tram City.
I imagine there would be a bit of skidding on those quad bogie tyres.Quote:

Mind you, the hot bitumen was pretty easy to damage by dragging tyres sideways.
Ian can correct me, but I'm pretty sure that come of the axles steer. At least that is what I have observed following some of the JR Stephens quad trailers around Ipswich.

You're right Mick, some do but it's a balancing act minimising tyre wear.
The steerable axles need constant maintenance and alignment or they can wear tyres quicker than non-steerable. JRs do mostly, relatively short runs, so more turning.
Some are a damped castor, others linked to the turntable.
Are you suggesting that I would operate illegally? Perish the thought. :angel:Quote:
