Openable structure

An Openable superstructure for substructure,

• comprising
• a collapsible top frame,
• a cover, in particular a tarpaulin, which can be connected to the top frame, and
• a drive for folding in and/or out the top frame, wherein the drive comprises a control and a drive device,
• wherein the drive device causes an endless, closed tension element which is tension-resistant to move,
• wherein the at least one tension element is coupled to at least one of two distal carriages of the top frame and moves the at least one of the two distal carriages back and/or forth as a function of an actuation direction of the drive,
• wherein the at least one tension element is wound several times around the drive device,
• wherein the control causes the drive to drive the at least one of two distal carriages with a power which is below a first threshold value for a power consumption of the drive in order to displace the at least one of two distal carriages,
• wherein the control causes the drive to drive the distal carriages for the duration of a first period with a power which is above the first threshold value for a power consumption of the drive in order to displace the carriage when a work peak is required through the pushing open of the cover,
• wherein a minimum time interval is provided between two successive first periods in which a power consumption exceeding the first threshold value is permitted, in which time interval the power consumption of the drive is limited in normal operation, and wherein the minimum time interval is at least as long as the first period.

An Openable superstructure for substructure, including a self-propelled truck, a truck, a semitrailer, a trailer, a container, a dump truck, a railway wagon, a building or the like;

• comprising
• a collapsible top frame,
• a cover, in particular a tarpaulin, which can be connected to the top frame, and
• a drive for folding in and/or out the top frame, wherein the drive comprises a control and a drive device,
• wherein the drive device causes an endless, closed tension element which is tension-resistant to move,
• wherein the at least one tension element which is tension-resistant is coupled to at least one of two distal carriages of the top frame and moves the at least one of the two distal carriages back and/or forth as a function of an actuation direction of the drive,
• wherein the at least one tension element which is tension-resistant is would several times around the drive device,
• wherein the control causes a locking pin to engage against a rotatable part of the drive when a stop position of the at least one of the two distal carriages has been reached, in order to block the distal carriages even when the drive is not driven, and
• wherein the control causes the drive to drive the distal carriages against a desired displacement direction of the distal carriages before the distal carriages are driven in the displacement direction, in order to disengage the locking pin and enable the release of the displacement of the distal carriages.
