ABSTRACT:
An open-topped vehicle, such as a freight vehicle, is covered by a single-use covering which includes a cage having a standard length and adjustment elements for taking up the difference between the cage length and the length of the vehicle. The cage includes cover supporting ribs that are spaced apart from each other according to preset distances. The covering also includes a flexible cover that is shrinkable and self-weldable upon the application of heat thereto, and is attached to the vehicle by multi-ply end joints which are formed by welding a first portion of the cover to a second portion of the cover to form a hem with a line located inside the hem. The line is attached to the vehicle. Patches can also be placed in locations on the cover needing additional, multi-ply protection.
