ABSTRACT:
A system and method is described for transporting articles, in particular for transporting container holding baggage pieces. At least two endless conveyor belts are sequentially arranged to define an upstream conveyor belt and a downstream conveyor belt for transport of articles in a transport direction from the upstream conveyor belt to the downstream conveyor belt. The conveyor belts are driven by drive-motors, in particular asynchronous motors, with the rotation speed of each drive motor being regulated depending on the weight of the articles located on the conveyor belt associated with the particular drive motor. The drive motors can be controlled by adjusting the frequency and/or voltage of the supplied electric power.
