Frequently Asked Questions

  • Are the dolly trailers new or used?

    All Tri Axle Converter Dollies we provide in Perth and throughout Australia are brand-new units, fresh from manufacturing with no previous use. Each dolly is built by experienced tradespeople, then undergoes detailed checks and performance testing to confirm it’s ready for work from day one. You’re not just purchasing a dolly trailer; you’re investing in equipment built to start performing from the first run.

  • Do you offer financing options for your dolly trailers?

    Yes. We offer competitive finance packages to help you get your Tri Axle Converter Dolly into service without delays. If you prefer, your own broker can conduct an independent inspection before finalising the purchase for extra peace of mind. Our aim is to keep the process clear and efficient, so you spend less time on paperwork and more time getting freight on the move.

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

    Definitely. You can select a custom paint finish at no added cost and choose from a variety of optional features to suit your freight type and working conditions. Custom-built dollies take longer to deliver than off-the-shelf stock, as each is produced from the ground up to your specifications. The result is a dolly trailer that fits your operation and your loads perfectly.

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

    Yes. Every Tri Axle Converter Dolly comes with a 12-month warranty covering defects in materials and workmanship under normal operating conditions. If any fault occurs during that time, we’ll arrange prompt repairs or a replacement to keep you on schedule. Our warranty is our assurance that we stand behind the quality and durability of every build.

  • What are the delivery times for ordered dollies?

    We regularly have stock available for immediate pickup in Perth or quick delivery across Australia. For builds made to order, the standard timeframe from deposit to delivery is up to three months. We believe the wait is worth it for a dolly trailer constructed for years of reliable service.

  • Do you provide after-sales service and support?

    Yes. Our commitment continues beyond delivery. We can assist with operational advice, arrange servicing, and respond to technical queries whenever needed. It’s all about keeping your Tri Axle Converter Dolly running smoothly and ready for the long haul.
