Oversize load transport in Melbourne

Permitted OSOM movements with pilots, planned routes and paperwork done.

When the load won't fit the rules

Oversize and overmass — OSOM — is freight that exceeds the standard dimension or mass limits and therefore can't simply be loaded and driven. Long structural steel, wide fabricated assemblies, plant and machinery, formwork and falsework components that are perfectly ordinary except that they're bigger than a truck is normally allowed to carry.

That turns a delivery into a planned movement. The route has to suit the load rather than the other way round: clearances, turns, bridges, and where pilots are required. Permits have to be in place before the wheels turn. None of that is difficult, but all of it has to be done properly, and it takes time that's worth building into your program.

Permits, routes and pilots

We handle the permitted movement end to end — the paperwork, the planned route, and pilots where the load calls for them. What we need from you is the real dimensions and mass, where it's collecting from, and where it has to be placed. Approximate figures are where OSOM jobs go wrong, so measured numbers are worth the effort up front.

Lead time depends on the permits the particular movement needs, so the earlier you tell us, the more options there are. If your load turns out to be within limits after all, we'll tell you that too and move it as normal freight.

Melbourne first, Sydney when it's needed

Most of our oversize work is in and around Melbourne, from our Braeside depot. Oversize and permit loads can run in Sydney and between Melbourne and Sydney too, so ask before you plan around one. The fleet is fully maintained with scheduled servicing and inspections, and every truck carries live GPS, so a permitted movement can be followed in real time. We've run construction freight and nothing else since 2021, including work on North East Link and the West Gate Tunnel.

Fleet & capacity

OSOM loads run on drop decks and flat tops, with the marking and communication gear a permitted movement calls for. These are typical fleet capabilities — an oversize load is planned and priced on its measured dimensions and mass, never from a table.

Drop deck trailersFor plant and loads where deck height decides the permit.
Flat top semis12.5 m or 13.7 m trailers depending on configuration.
PayloadApprox 20–24 tonnes.
Extendable trailersFor long loads that exceed a standard flat top.
Site equipmentHandrails, flashing lights, oversize equipment and UHF radios.

Common questions

Does my load need a permit?

It depends on its measured dimensions and mass, and the vehicle it goes on. Permits are checked per load. Send the real measurements, not estimates, and we'll tell you.

How much notice do you need for an oversize load?

Lead time depends on the permits the movement needs, so the earlier you tell us, the more options there are.

Do you run oversize loads in Sydney?

Yes, they can run in Sydney too, though most of our oversize work starts in Melbourne. Ask before you plan around one.

How much does oversize transport cost?

Every job is quoted on the load, distance and time on site. Send the details and we'll come back with a price.
