ABSTRACT:
A transportation system for a transportation device has a transportation chain having a plurality of chain links joined to form an articulated endless chain and with a sprocket to reverse the chain. The transportation chain has several equally-spaced guide elements which, in a transportation area of the transportation device are guided along a guide rail. The guide elements are formed of sliding elements that are mechanically linked to the transportation chain and slide along the guide rail when the transportation system is in motion. An outer circumference of the sprocket has recesses which at least partly accommodate the sliding elements.
