Abstract: The present invention shows a transport system for the transport of bulk goods, in particular of concrete, comprising a transport belt for the conveying of the bulk goods to an unloading point, wherein a rotary arm is provided which is rotatable about a vertical axis of rotation and which transports bulk goods to its free end and unloads them there. In this respect, the rotary arm is supported at a holder which is or can be arranged at a stationary support column such that the axis of rotation of the rotary arm extends eccentrically to the support column, with the rotary arm advantageously being arranged next to the support column, viewed from above, in at least one rotational position. The invention furthermore shows a corresponding support column as well as a method for the rebuilding of the transport system.
