Series-Connected Dual-Axis Self-Unloading Hydraulic Trailer (ATM4000)

We proudly introduce the Series-connected dual-axis self-unloading hydraulic trailer (ATM 4000kg) — a robust, heavy-duty trailer built to handle demanding hauling tasks with confidence and compliance.

Each unit is rigorously tested and fully certified, meeting Australian Design Rules (ADR) and RVSA standards to ensure your safety, reliability, and legal compliance on Australian roads.

Engineered for superior load-bearing strength, this trailer features 60mm 6-leaf rocker roller springs, a 1800mm 100×50mm RHS drawbar, and your choice of either a 50mm 2000kg over-ride coupling or a 50mm 3500kg electric coupling.
Every design detail is focused on providing smoother towing, improved stability, and easier handling even under heavy loads.

Available in a range of sizes and configurations—including 8×5, 10×5, and 10×6—our tandem box trailer series offers exceptional versatility to suit various applications, from construction and landscaping to general transport.
