AAA Trailers – Tri Axle Converter Dolly Trailer in Adelaide

Overview: Tri Axle Converter Dolly Trailer

Hauling heavy through Adelaide’s freight corridors demands a dolly that tracks straight, pulls smooth, and takes on the toughest jobs without flinching. The AAA Trailers Tri Axle Converter Dolly delivers rock-solid stability, balanced weight distribution, and reliable control for heavy haulage and long-distance linehaul. Its tri-axle configuration spreads the load evenly, cutting wear on your prime mover and trailers while keeping your combination steady at speed.


The heavy-duty 6.4-metre chassis carries an 18-tonne ATM and comes equipped with K-Hitch 22.5” drum brake axles and a tough tri-axle suspension system, with an optional air suspension upgrade for operators chasing extra ride comfort. A 50mm SAF tow eye and bolt-in turntable provide a secure, no-compromise connection you can trust from Adelaide metro runs to interstate hauls.


Standard features include full LED lighting for visibility in all conditions, with optional add-ons such as a road train kit, spare wheel, and hub odometer to suit your operation. Built for serious freight work, this dolly keeps your loads stable, your coupling secure, and your schedule tight.

Frequently Asked Questions

  • Are the tri axle converter dolly trailers new or used?

    Each Tri Axle Converter Dolly we deliver in Adelaide is a completely new unit, leaving our facility with no prior operational history. Skilled technicians manage every stage, from fabrication to the final quality check, so by the time it reaches your yard, it’s already proven fit for the road. You’re getting equipment ready to start earning from the very first trip, whether linking trailers for interstate linehaul, regional transport, or heavy freight tasks.

  • Do you offer financing options for your tri axle converter dolly trailers?

    Yes. We provide a range of flexible finance packages to help you put your dolly to work without putting unnecessary strain on your cashflow. If you choose to go through your own broker, they can arrange a pre-purchase inspection, giving you added peace of mind before committing. We aim to keep the process straightforward, quick, and free from avoidable delays so you can concentrate on keeping loads moving.

  • Can I customise the specifications of the tri axle converter dolly trailers I order?

    Yes. From complimentary paint finishes to a variety of optional extras that suit your freight needs, we can build a dolly to your specifications. As each one is manufactured from the chassis up, the build time will be longer than stock models, but the end result is equipment made specifically for your work and operating environment.

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

    Yes. Every Tri Axle Converter Dolly comes with a 12-month warranty that covers defects in materials and workmanship under normal operating conditions. If any fault arises during that period, we will arrange repairs or a replacement without delay. For us, the warranty is more than a formality as it’s our promise to stand behind everything we produce.

  • What are the delivery times for ordered tri axle converter dolly trailers?

    We frequently have units in Adelaide ready for prompt delivery. For fresh builds, the typical lead time is up to three months from deposit. This timeframe allows us to uphold our strict quality standards so you receive a dolly built for years of reliable service.

  • Do you provide after-sales service and support?

    Yes. Our commitment continues well beyond delivery. We can offer operational guidance, arrange scheduled servicing, and answer any technical questions. The objective is to keep your equipment performing at its best so your freight stays on schedule without downtime.
