The cover assembly has an arched shape lid within which are located tilted piston devices for pivoting the cover assembly over the box body. The piston devices extend between the top edges of the front and the rear wall of the box body up to locations inside the lid adjacent the respective front and rear walls. The lid is provided with openings for loading the box body with loose goods.
