AAA Trailers – 45’ Flat Top Extendable in Melbourne

Overview: 45’ Flat Top Trailer (Extendable)

Need a trailer that can handle everything from standard freight to extreme over-length cargo? The 45’ Flat Top Extendable gives you the range and strength to move it all.


With a closed length of 13.72m that stretches out to 21.4m, it gives operators the deck space they need for machinery, beams, containers, and long structural freight without compromising payload.


Its 47-tonne ATM and approximately 11-tonne tare deliver serious capacity, while the high-tensile steel mainframe, forklift-rated 5mm steel chequer plate floor, and 3-way container pins keep it ready for anything from local runs in Melbourne or across Victoria to cross-country linehaul work.


Rolling on K-Hitch tri-axle airbag suspension with 22.5” drum brake axles, and backed by a multi-volt EBS braking system, it offers stability, control, and dependable stopping power across varied road and load conditions.


Standard fit-out includes a dual-position kingpin, steel gates, LED lighting, a stainless steel water tank, and steel toolboxes. Operators can also spec it further with optional upgrades to match their freight profile and fleet requirements.

Frequently Asked Questions

  • Are the trailers new or used?

    Every 45’ Flat Top Extendable we supply is a brand-new build, never refurbished or second-hand. Each unit is carefully assembled, undergoes a full quality inspection, and is road-tested to confirm it’s ready for immediate fleet use.

  • Do you offer financing options for truck trailers?

    Yes. We have competitive finance options available for the 45’ Flat Top Extendable, giving operators the flexibility to expand their fleet without putting strain on cash flow. You’re also welcome to have your preferred finance broker review the trailer before finalising your order.

  • Can I customise the specifications of the trailers I order?

    Absolutely. You can select a custom paint finish at no additional cost and add from a range of optional features to suit your transport requirements. Just keep in mind that custom builds generally require longer lead times than stock units already ready for dispatch.

  • Do you have a warranty policy for your truck trailers?

    Yes. Each 45’ Flat Top Extendable is backed by a 12-month warranty covering defects in materials or workmanship under normal operating conditions. If an issue arises during this period, we will arrange prompt repairs or replacements to keep you on the road.

    We occasionally have 45’ Flat Top Extendable units in stock for faster delivery across Victoria and Australia-wide. If a new build is required, the typical turnaround is up to three months from the date your deposit is received.
