Abstract

An openable superstructure for a substructure (14), i.e., a self-propelled truck, a truck, a semi-trailer, a trailer, a container, a dump truck, a railway wagon, a building or the like, comprising a foldable top frame (16), a cover (12) for connection to the top frame (16), in particular a tarpaulin, and a drive (70) for folding in and/or out the top frame (16). The drive (70) causes at least one at least tension-resistant tension element (71) to perform a movement and which can be coupled to a distal carriage (32′) of the top frame (16), moving the distal carriage (32′) back and/or forth based on the drive's actuation direction. The drive (70) comprises a driven first rotating body (73) and a second rotating body (74), arranged adjacent to one another, forming a drive device (75) The tension-resistant tension element (71) is wound several times around the drive device (75).
