<p>A b s t r a c t : Rope hoist apparatus comprising a single drivendrive pulley (15) in which the rope (11) is pressed by a spring-loaded lever (32) by two pressure rollers (29 and 30) into the rope groove (19). The pressure rollers (29 and 30) are so arranged that the rope tip (41) of the rope (11) can easily be pushed beneath the pressure rollers (29 and 30), The rope (11) is conducted after being lifted out of the rope groove (19) via a lateral ramp (60) onto a running face (21) of the drive pulley (15) which is disposed adjacent the rope groove (19) and over which the slack run (13) is conducted in a manner preventing damage parallel to the load run (12). See Fig. 1.</p> |
