• and wherein the discharge device includes a pivot or lifting element that mechanically couples and engageably operates between the transport unit and the transport container to lift and displace at least one side of the transport container from the transport unit without entirely detaching from the transport unit during a tipping operation for unloading a goods item on the transport container;
• loading of the transport container with a goods item;
• picking up of the loaded transport container by a transport unit and connection of the transport unit to the transport container by means of the retaining mechanism;
• conveying of the loaded transport container by the transport unit;
• and
• unloading of the goods item by means of the discharge device or by detachment of the connection between the transport container and the transport unit by means of the retaining mechanism and discharge of the transport container loaded with the goods item.
