  • Patent number: 5642802
    Abstract: A conveyor apparatus has a plurality of pivotable load-bearing elements which are disposed one behind the other and travel along an endless track that has at least one unloading station where the load-bearing elements are unloaded by a pivoting action. Two switching elements disposed at the unloading station are switchable individually between an inactive state and an active state for pivoting the load-bearing element. One of the switching elements is divided into first and second switching parts so that a load-bearing element disposed in the region of the unloading station can be operated selectively with one or the other of the switching parts for the purpose of pivoting the load-bearing element for unloading.
