Efficient road transport paves the way for reduced emissions
As demand for goods increases, so do the need for transports. One energy-efficient answer to tomorrow’s goods transports is fewer trucks and heavier loads – a solution that also improves road safety.
The solution is called Duo2 which is a research collaboration between several transport industry companies and government agencies in Sweden. The purpose of the project, a joint initiative taken by Volvo AB, the Swedish Transport Administration and DB Schenker along with several other companies, is to investigate the potential for transporting mixed cargo loads on the existing road network more efficiently. This involves testing longer, and heavier vehicle combinations than the ones currently permitted in Europe. At present the limits in Sweden are 25.25 metres and 60 tonnes laden weight, while the larger part och Europe has 18,75 metres and 40 tonnes as the limits.
Longer trucks and heavier loads
The Duo2 project is putting two vehicle combinations to the test. The first, the Duo-Trailer, is a truck with two semitrailers. The two trailers are connected with a dolly with two axles, connectors and a fifth wheel. When fully assembled the vehicle measures 32 metres in length with a gross weight up to 80 tonnes with a full load. The second Duo2 vehicle, the Duo-CAT, is scheduled to be taken onto the roads during the spring of 2015. The combination consists of a truck with two centre axle trailers. This is what is known as a swap-body combination; both the truck and the trailers have removable containers with fold-up legs that can be used to stand the container on the ground.
