摘要

A round supporting body (9) is arranged in arms (8) spread in a V-shape of a supporting bearing (7) of a boom. Back gears (24) which can be driven by hydraulic motors (26) are arranged in recesses (23) of the supporting body (9). The back gears (24) mesh with a central spur gear (27). A flanged shaft is guided inside the sleeve in such a way as to be locked against rotation. A bucket-wheel body (30) is flange-mounted on the flanged shaft. The operating elements of this bucket wheel are protected from increased wear as a result of contamination by bulk material. Furthermore, swivelling about the essentially vertical axis of the universal joint is possible without hindrance by the supporting boom. <IMAGE>
