In June 2024, Schmitz Cargobull unveiled the EcoDuo road train, designed to reduce CO2 emissions and enhance logistical efficiency. The system comprises two standard curtain-sided semi-trailers connected by a dolly and pulled by a three-axle tractor, extending to a total length of 31.5 meters. This articulated vehicle can weigh up to 76 tons with a three-axle tractor, as used in Scandinavia, or up to 70 tons with a two-axle tractor, as in Spain. This flexible concept primarily employs standard trailers, offering numerous advantages over conventional long articulated trucks.
Unlike traditional concepts that often require trailers of different lengths and are not combinable for flexible use, the EcoDuo allows for easy separation of trailers between two tractors at border crossings, distribution centers, or specific regions. This facilitates continuous and cross-border transport, overcoming the limitations imposed by different national laws. Consequently, no additional investments in trailers beyond the existing standard ones are necessary, making the concept truly modular.
The ability to couple or decouple standard semi-trailers enables the use of all infrastructure with individual trailers and loading them onto trains. Loading and unloading procedures remain unchanged. According to Schmitz Cargobull, compared to conventional combinations with a total vehicle weight of 40 tons, the EcoDuo offers several advantages: reduced fuel consumption and CO2 emissions per ton transported, decreased axle loads, increased road capacity, and reduced traffic due to fewer vehicles with higher capacity. Additionally, it would lessen the stress on roads and bridges and help address the driver shortage.
"One driver, two trailers for long-haul trips," explained Andreas Schmitz during a press conference. "Unlike previous concepts of longer vehicle combinations, existing trailer fleets can still be utilized. With two standard semi-trailers, the existing dimensions in the transport sector remain unchanged."
