Abstract: A cover for a load-carrying space comprising a tarpaulin, which mechanically can be drawn across the upwardly open load-carrying space and cover, and which can be removed in order that the load-carrying space is open at the top, the cover comprising supporting strips at intervals being secured to the cover material, which supporting strips reach across the load-carrying space. The supporting strips may, driven by a motor via an endless chain, slide at right angles to their longitudinal direction, controlled in a guide rail at each end of the load-carrying space. A hinge is located in the middle of the guide rails in order that half of the guide rails can be raised by a bellow cylinder, when the cover is to be drawn completely aside. Hereby, a cover of a very simple mechanical construction is obtained, totally insensitive to dirt of any kind. The cover may be operated from the cab of the lorry.
