AAA Trailers – 45’ Flat Top Extendable in Adelaide

Overview: 45’ Flat Top Trailer (Extendable)

Moving freight that blows past standard lengths? The AAA 45' Flat Top Extendable is one of the most versatile extendable trailers for sale in Adelaide, purpose-built for operators moving everything from heavy machinery and steel beams to containers and extreme over-length loads. With a closed deck of 13.72 m that stretches out to an impressive 21.4 m, it gives you the reach to handle big gear while keeping your payload capacity on point.


With a 47-tonne ATM and around 11 tonnes tare, it’s got the grunt for serious work. The high-tensile steel chassis, forklift-rated 5 mm chequer plate deck, and 3-way container pins make it just as at home on the wharf as it is running regional freight or pushing long-haul across the Nullarbor.


On the bitumen, K-Hitch tri-axle airbag suspension, 22.5” drum brake axles, and a multi-volt EBS braking system give you solid stability, predictable tracking, and strong stopping power in all conditions.


From day one, it’s ready to earn with a dual-position kingpin, steel gates, LED lighting, a stainless water tank, and steel toolboxes. And if you’ve got a specific freight profile, optional upgrades let you set it up to fit your fleet and the work you do.
