The invention discloses a fan-shaped magnet yoke permanent magnetic crane which belongs to the technical field of permanent magnet lifting equipment. The fan-shaped magnet yoke permanent magnetic crane structure comprises an upper magnetic yoke disk and a lower magnetic yoke disk which are installed on a central shaft (1) and can relatively rotate, the magnetic yoke disk comprises fan-shaped magnet yoke irons (16, 16a) and rare earth permanent magnetic bars (9, 9a), the center of the upper magnetic yoke disk and the lower magnetic yoke disk are respectively provided with coaxial magnetic yoke disk center small round cakes (3, 15) made of a non ferromagnetic material, a thrust bearing(4) is installed between the magnetic yoke disk center small round cakes (3, 15) of the upper magnetic yoke disk and the lower magnetic yoke disk, and the height of the lower rare earth permanent magnetic bar(9a) is less than the height of the upper rare earth permanent magnetic bar (9). The independent fan-shaped magnet yoke irons (16, 16a) are respectively in solid connection with the center small round cakes (3, 15) by circular press plates (31, 32, 33, 34) and a flat head bolt (30). The fan-shaped magnet yoke permanent magnetic crane eliminates the magnetic line short circuit, improves the permanent magnetic crane lifting ratio; and due to no residual magnetism after unloading, a very small iron magnetic material may not retained.
