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