2 New heavyweights for the international transport of construction materials. Recently, two new Volvo tractor units were delivered… to H.M.Verploegen. Both tractor units will be used in the distribution of building materials throughout the Benelux, Germany, and France. These tractor units are equipped with an engine that meets the environmental standard Euro 6, and they come with I-See. This unique feature registers the topography of the road and stores it in a central database. While driving, this knowledge is then used to save up to 5% of fuel.
