Abstract:
A lifting apparatus (1), configured to lift poultry legs (9) conveyed suspended in a row, comprises a conveying device (11) and a poultry leg lifting device (12). The poultry legs (9) can be suspended by their ankle joint balls (911) in poultry carriers (131) of the conveying device (11). The poultry leg lifting device (12) has a poultry leg positioning device (70) having at least one positioning element (71-78, 141) which, with weight unloading of the poultry carrier (131), lifts the conveyed poultry legs (9) with the ankle joint balls (911) in a poultry leg lifting way (h) into lifted ankle joint ball positions. A carrier lifting device (13) is configured to lift each foot hook-in device (31) to suspension heights which correspond with the ankle joint ball positions lifted in the poultry leg lifting device (12). For this purpose, the carrier guiding device (132) has a dynamically movable lifting guiding member (4) and a guiding bearing device (42) which carries the lifting guiding member (4), in conjunction with a weight unloading of the poultry carriers (131) effected by the lifting of the poultry legs (9), in a vertically movable manner. The foot hook-in device (31) is mounted on the poultry carrier (131) in such a manner that it is freely vertically movable.
