The supporting elements are mounted pivotally about a horizontal pivot axis to the drive and structured such that a center of gravity of the supporting element with or without an empty or loaded container carrier is arranged below and vertically aligned with the pivot axis when the supporting element is in an upright position such that each supporting element is free to pivot about the associated pivot axis under the effect of gravitational forces acting on the supporting element for maintaining the supporting elements in an upright position while travelling along the path. ##
