AAA Trailers – Tri Axle Converter Dolly Trailer in Melbourne

Overview: Tri Axle Converter Dolly Trailer

The AAA Trailers Tri Axle Converter Dolly provides reliable stability, balanced load distribution, and consistent performance for demanding haulage operations. With its tri axle configuration, it spreads the weight evenly, improving handling and reducing stress on the rest of the rig, which makes it ideal for road train operations and big freight assignments.


Engineered on a robust 6.4m frame, it’s rated for an 18-tonne ATM and runs on K-Hitch 22.5” drum brake axles with a heavy-duty tri-axle suspension system, with an air suspension upgrade available for improved ride comfort. A 50mm SAF tow eye and bolt-in turntable ensure strong, secure coupling for consistent performance across busy freight routes in and out of Melbourne, through Victoria, and across Australia.


Standard features include full LED lighting for clear visibility in all conditions, while options such as a road train kit, spare wheel, and hub odometer let you fine-tune the setup to your operational needs. Built to handle demanding linehaul work, this dolly keeps your loads steady, your connections secure, and your schedules on track.

Frequently Asked Questions

  • Are the dolly trailers new or used?

    All Tri Axle Converter Dolly units we supply are factory-fresh builds, never second-hand or reconditioned. Each dolly is manufactured to strict standards, tested under load conditions, and given a complete inspection so it’s ready to go straight to work the moment it joins your fleet.

  • Do you offer financing options for the dolly trailers?

    Yes. We provide competitive finance options for the Tri Axle Converter Dolly, helping you add capacity to your fleet without disrupting your cash flow. If you prefer, you can involve your own broker to inspect and review the unit before purchase, giving you added peace of mind.

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

    Yes, you can. From a no-cost custom paint colour to optional extras suited to your linehaul or road train work, we can configure your dolly to meet your operational needs. Just keep in mind that a made-to-order unit will require more build time than stock models ready for immediate dispatch.

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

    Every Tri Axle Converter Dolly is covered by a 12-month warranty against defects in materials and workmanship under normal operating use. If an issue arises, we’ll arrange prompt repairs or replacements to keep you on schedule.

  • What are the delivery times for ordered dolly trailers?

    We often have Tri Axle Converter Dolly units available for fast delivery across Melbourne, throughout Victoria, and Australia-wide. For new builds, production and delivery usually take up to three months from the time your deposit is received.

  • Do you provide after-sales service and support?

    Yes. We continue to support you long after delivery. We can provide operational guidance, technical assistance, and help with organising servicing so your Tri Axle Converter Dolly performs reliably on freight corridors in Victoria and across the country.
