A hoisting arrangement for a trolley (1) of a container crane with two motor-driven cable drums (2a, 2b), with cable rollers (4a-4d) arranged on the roller traverse (5), and with hoisting cables (3a-3d) guided between the cable fixed points (8a-8d) and the cable drums (2a, 2b). Hoisting arrangement provides cable drums (2a) and (2b) arranged, together with their drives (6a, 6b, 7a, 7b), offset in parallel by the drum diameter (12). A maximum cable distance (10) with fully wound cable drum (2a, 2b) is provided to correspond approximately to the distance (11) of the cable roller pairs (4a, 4b) and (4c, 4d) on the roller traverse (5), as well as approximately to the distance (9) of the cable fixed points (8a, 8b) and (8c, 8d) on the trolley frame (1). The cable drums (2a, 2b) are of double-thread design. During lowering, the cables (3a, 3b, 3c, 3d) run on the cable drums (2a, 2b) in the inward direction and define the cable runoff path (15).
