摘要： The rope (1) is guided through the nip (24) of a pair of pulleys (6, 7) and is otherwise extended in an S-shape about the pulleys (6, 7) of this pair. Each of these pulleys (6, 7) is connected for rotation with two gear wheels (26, 27) meshing with each other in the zone of the nip (24). Thereby high static friction is ensured between the rope (1) and the pulleys (6, 7), and a slippage of the rope (1) on the pulleys (6, 7), which is life-endangering for the descending person, is reliably prevented. A speed-dependent brake (31) and a brake (33-37) stressed by the weight (G) of the downwardly roping person effect a rate of descent that is extensively independent of this weight.
