| (54) | Equipment for preventing formation of a slack rope on a rope drum |
| (57) The invention concerns equipment for preventing formation of a slack rope on a rope
drum (1). On its outer periphery the rope drum (1) has one or more spiral rope grooves
(2), which extend around the rope drum (1) and which extends/extend mainly over the
entire axial length of the rope drum (1). In connection with the rope drum (1) is
arranged a pressing roller (4), which is loaded flexibly against the rope drum (1)
and which has an axis of rotation essentially in parallel with the rope drum's (1)
axis of rotation and which presses the rope (3) to be rolled against the rope drum
(1) to keep the rope (3) in the rope groove (2). According to the invention, a guide
ring (6) or other such device is placed in a rope groove (2) next to the rope (3)
rolling up on the rope drum (1) to roll against the rope drum (1), so that the rolling
point of said guide ring (6) or other such device on the rope drum (1) is in a groove
next to the rope (3) rolling up on the rope drum (1) essentially in a plane extending
through the axes of rotation of the pressing roller (4) and the rope drum (1). The
rope (3) rolling up on the rope drum (1) is hereby guided and supported on one side
by the rope layer already rolled up on the rope drum (1) and on the opposite side
by said guide ring (6) or other such device.
