According to the latest safety regulations, loose material can already be transported only by trucks with tarpaulins. SIKU also brings these current regulations to life in the children’s room. A Mercedes-Benz Actros truck tractor pulls a three-axle dump trailer with a movable hopper body and an attachable flexible plastic roof tarp. The rear flap of the self-loading body is movable. It can be opened whether the roof tarp is on or not.
