A heavy-duty vehicle configuration featuring two rear axles is commonly employed for hauling substantial loads. This arrangement effectively distributes weight, enhancing stability and increasing the overall carrying capacity compared to single-axle trucks. An example includes a dump truck used in construction, typically equipped with this dual-axle system to transport gravel, sand, or asphalt.
The utilization of such a configuration provides several advantages. It allows for heavier payloads, improving efficiency by reducing the number of trips required for a given task. Furthermore, the enhanced weight distribution minimizes stress on road surfaces, contributing to infrastructure longevity. Historically, the adoption of this design represented a significant advancement in trucking, enabling the transport of larger quantities of goods and materials essential for industrial growth.
