Right now there are two seperat tests ongoing parallel (July 2019).
The firts project running was the “DUO-trailer” with contains a tractor with dubbletrailers (about 32 m). This combination is driving between Gothenburg and Malmö on the E6 and on connection to Schenkers terminals in Gothenburg and Malmö. The test has been ongoing since 2012 and the combination has traveled about 410 000 km as the Duo-trailer (July 2019). Our dubbletrailer has dubble amount of load compared to a European tractor with a singletrailer, see picture below.
The later test “DUO-CAT” contains a truck with two CATs (27,3 m). The DUO-CAT project started in March 23rd 2015. This combination drove under the first phase singletrips on the night as the DUO-CAT and distribution on the daytime (truck and one CAT).The singletrips at night gave about 52 000 km as DUO-CAT before phase two started in Septembre 2018 at Kinnarps AB.The kombination has driven about 90 000 km at the other location.
If a comparison between different combinations with the same amount of transported load is done the result shows that the fuel consumption depends on which combination is selected for the mission. Shown below is an example where different types of combinations transport 200 pallets (600 kg/pallet) from Malmoe to Gothenburg.
