Triple Axles. Maximum Capacity. Unmatched Versatility.
The Step Deck Tri-Axle Trailer is built for operators who need heavy-duty performance and maximum flexibility across diverse hauling applications. With its robust 90,000 lb GVWR and tri-axle configuration, this trailer tackles taller, heavier loads that standard units can’t handle. The coil bed design, spring-assisted tail, and removable neck ramps deliver the loading flexibility and weight distribution that construction, machinery, and freight haulers demand for profitable operations.
The tri-axle configuration is where this trailer really shines – enhanced weight distribution and superior stability that lets you haul heavier loads with confidence. Whether you’re moving steel coils, construction materials, or heavy machinery, those three axles spread the load efficiently while maintaining excellent road handling. The coil bed design accommodates specialized freight that other step decks struggle with.
Loading versatility sets this trailer apart from standard step decks. The spring-assisted tail reduces operator strain while speeding up loading cycles, and the removable neck ramps give you multiple loading options for different freight types. This flexibility means you can take on diverse loads and adapt to various job site conditions without needing multiple specialized trailers.
Built for operators who need one trailer that can handle multiple freight categories efficiently. The robust construction stands up to the demanding loading patterns of mixed freight operations, while the tri-axle setup provides the capacity and stability for heavy loads that would overstress lighter configurations. Every component is engineered for the versatility that keeps diverse hauling operations profitable.
For haulers who need maximum capacity combined with loading flexibility, the Step Deck Tri-Axle delivers the heavy-duty solution. When you’re competing for loads that require both height clearance and serious weight capacity, this trailer provides the strength and adaptability that separates successful operators from the competition.
