Thread: MGB 3t trailer

This is a trailer, that has a GTM of 4989Kg (1452Kg tare weight) designed to carry 3 ton of medium girder bridge components. And as we said it is overwidth (at least for NSW) by 60mm, so nothing I have is wider than this trailer.

It is also 5690mm long.

What is the advantage in registering a trailer on Special Interest rego? Trailers cost bugger all to register anyhow and use is not restricted if on normal reg.

Is that still true on trailers over two tons GTM?

From my personal perspective, the only thing I have with air brakes that is capable of towing my trailer is my Mk3 Inter and that is on Historic Rego, so the issue is moot.

Checked with Qld. Transport Full rego $186, less $86 concession for Special Interest rego.

Historic Conditional Registration in NSW $22.

Classed as a heavy trailer because of its tare and aggregate. QT require a Safety Certificate and inspection and measurement by either by the Dept. or a Registered Heavy Vehicle Inspector. Private reg. not applicable to a heavy trailer, closest category is "not for profit".

Upon inspection, there are basically two areas where the trailer is over width:

• The clearance lamps on the end of the outriggers take the width out past 2500mm, move the clearance lamps below the outriggers and that problem is solved.
• The more difficult area is the axle, the road wheel centres and wheel nuts are the full 2560mm. The only option is to have at least 60mm taken out of the centre of the axle and move the spring mounts out 30mm on each side. This is likely possible but will move the tyre inner wall very close to the chassis and spring pack.

It is what I have to do if I ever hope to register and use the trailer.

Thinking outside the square...
Why register it?
If you could get it onto the back of the Mk3 it would be legal to carry as it's indivisable.
(It would be no wider than most curtains on chiller tautliners running the highway).
Drop it off for display days(subject to site registration rules).
Some sites have earth ramps that could be used.
