Abstract:
An axial support of a winding drum in a hoisting apparatus comprising a frame, a grooved winding drum supported substantially perpendicular to its longitudinal axis against the frame by bearings, a hoisting rope and machinery, the winding drum comprising at least one axial support element close to the circumference of the winding drum and the frame comprising at least one axial support element close to the circumference of the winding drum, wherein at least one axial support element of the winding drum or at least one axial support element of the frame is discontinuous in the circumferential direction of the winding drum and the axial support element of the winding drum and the axial support element of the frame are arranged in respect of each other such that the movement of the winding drum in the direction of its longitudinal axis, which is caused by an axial component of the rope force of the hoisting rope, is hindered at least in one direction.
