Dolly & Road Train Repair in Darwin

Dolly and road train components experience significant stress across long-distance operations, making precise repairs essential to safety and fleet longevity. At Cadillac Transport Repairs, we specialise in mechanical repairs for dollies and road trains, using industry-compliant methods and heavy-duty parts. From worn drawbars and fifth-wheel hitches to braking systems and suspension setups, our repairs are engineered for durability under constant load.

Our team understands the technical standards required for multi-trailer combinations in the Northern Territory. All work is carried out in our fully equipped Winnellie workshop using equipment calibrated for heavy transport. Whether you're managing a fleet or a single long-haul setup, we deliver efficient turnaround times and fully documented repair work.

We assess each road train or dolly on a component-by-component basis, starting with drawbar integrity and coupling alignment. Cracking, fatigue, and distortion are identified early to prevent structural failure. We also check pivot points, axle alignment, and mechanical linkages to ensure the entire towing system is operating under correct tension and movement range.



Brake systems are tested against compliance thresholds, with service brake function, air pressure delivery, and emergency response components thoroughly reviewed. Where required, replacement of valves, brake chambers, and slack adjusters is carried out using high-quality parts to meet heavy vehicle regulations. Our workshop is configured to handle oversized trailers and dollies, reducing wait times and allowing for accurate testing under loaded conditions.
