AAA Trailers – Tri Axle Converter Dolly Trailer in Brisbane

Overview: Tri Axle Converter Dolly Trailer

The AAA Trailers Tri Axle Converter Dolly is purpose-built to keep heavy haulage combinations steady and balanced across long distances. Its tri axle setup enhances weight distribution and tracking, giving operators the control and reliability needed for large freight tasks and road train work.


Capable of managing an 18-tonne ATM on a durable 6.4m frame, this unit runs on K-Hitch 22.5” drum brake axles with a heavy-duty tri-axle suspension system, with an air suspension option available for added ride quality. The 50mm SAF tow eye and bolt-in turntable provide secure coupling for consistent on-road performance.


Full LED lighting improves visibility in all conditions, while optional extras such as a road train kit, spare wheel, or hub odometer allow you to match it to your operational needs. Built for the demands of Brisbane, Queensland, and haulage routes right across Australia, the AAA Tri Axle Dolly delivers the strength and stability to keep your fleet moving efficiently.
