The invention relates to a power transmission and bearing arrangement for a drum, the drum (1) being provided for a rope (2) that exerts a tangential force on the circumference of the drum, and the arrangement comprising the mounting of the drum in bearings (7 to 10) to a frame structure (6) and a drive arrangement for rotating the drum, the drive arrangement comprising at least one member (3) that is in drive engagement with the drum surface. To simplify the structure and to eliminate the bending moment acting on the dru m, the drum bearing arrangement comprises means (7 to 10) that carry the drum a nd support the drum surface (1) to the frame structure (6) directly from the outer and inner surfaces (4, 5) of the drum surface, the point where the rop e is unwound from the drum being located within the bearing area when seen fro m the end of the drum.
