Abstract: The invention relates to an openable structure for a substrate, such as a lorry, trailer, semitrailer, railway wagon, dumper truck or container, comprising a tarpaulin framework to which, for example, a tarpaulin made of weather-resistant material or a plurality of hingedly couplable wall elements can be connected, wherein the tarpaulin framework has a plurality of slides which are shiftable along at least one guide, wherein the guide comprises a longitudinal member element along which the slides are shiftable. An openable structure permitting smooth opening and closing of the structure is provided according to the invention in that the longitudinal member element is arranged adjustably at least in sections in a direction transversely with respect to the shifting direction of the slides.

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).
