ABSTRACT:
An automatically or manually operable closure system for a closing flap on a transport container is situated on the container frame and a docking stand at an unloading station. A rotating device for moving the closing flap is provided on the docking stand and a locking device for locking the closing flap in the closed position is provided on the container frame. A flap shaft, whose other end is mounted rotatably in the container frame and is implemented as a first connection element, engages axially to the rotational axis of the closing flap. The first connection element is axially coupled using a torsion-fixed tongue-groove pair to an axially displaceable second connection element. Formfitting coupling elements are provided on the second connection element and on the driveshaft for moving the closing flap.
