Abstract
An arrangement for conveying material to be conveyed along a conveying plane, in particular for freight-loading systems in freight compartments, preferably of aircraft is disclosed. The arrangement provides that driving material to be conveyed along a conveying plane, with which safe, reliable transport of the material to be conveyed is ensured with low wear of the conveying roller under widely varying operating conditions. This is achieved in that, in a drive unit, the conveying roller is connected to a first drive and an associated first activating unit for producing a requisite traction force for moving the material to be conveyed along the conveying plane. There is a second drive having an associated second activating unit for producing an adequate pressure force of the conveying roller against the material to be conveyed, and control electronics part is provided, which coordinates the two drives, which can be activated independently of one another, as a function of a motion state of the material to be conveyed. The motion state is detected at least by the internal sensor unit, is designed as a self-testing device.
