<p>An axial support of a winding drum (4), i.e. a support in the direction of the longitudinal axis of the winding drum (4), in a hoisting apparatus (1) comprising a frame (2), a grooved (5) winding drum (4) supported substantially perpendicular to its longitudinal axis against the frame (2) by bearings (3), a hoisting rope (10) and machinery. The winding drum (4) comprises at least one axial support element and the frame (2) comprises at least another axial support element, and at least either the axial support element of the winding drum (4) or the axial support element of the frame (2) substantially extends round the circumference of the winding drum (4). The axial support element of the winding drum (4) and the axial support element of the frame (2) are arranged in respect of each other such that the movement of the winding drum (4) in the direction of its longitudinal axis, which is caused by the axial component (13) of the rope force of the hoisting rope (10), is hindered at least in one direction. <IMAGE></p> |
