Thread: A question for truckies

Hi Ron,
I have been noticing a few semis and B doubles with 4 axe trailers on the Hume recently.
I don't know why, I'm sure V8Ian, D2Dave or Tins will be along shortly to enlighten us.

They're becoming more popular, but only an advantage if the trailer is operating on approved routes.
On non-approved roads the extra tare weight becomes a disadvantage.

This might help, Ron.

See a few driving up & down the hume.

Seem to be mainly reefer vans that are also longer than 40 ft.

I'm fairly sure I saw one recently on Great Northern Hwy. The forward most axle was lifted, so 3 on the ground and the 4th tied up so the wheels were in the air. It didn't have a lot on it at the time.

Most of the trailers I see in Oz have 3 axles on the trailer, i.e., 4+4+4 making the semi a 22-wheeler.

However, I’m in NZ at the moment and I’m seeing a lot of trailers with 4 axles (I’m not referring to dog trailers), making the combination a 26-wheeler.

My question is: Are 4-axle trailers used in Australia? I don’t recall ever seeing one. I’m not referring to low loaders, just conventional trailers.

As noted by others yes they are becoming more common.

Also see a few 3 rear (drive) axle trucks around now.

Usually two drive and one lazy axle, commonly but inaccurately referred to as tri-drive. Tri-drive is more a WA thing, except on body trucks referred to as ten wheelers.

We have trucks with 4 axles on the trailer around Orange. ANL use them to transport product.

You will love this truck I snapped a picture of while in Jordan.
