摘要： The proposed winch (8) has a drive roller (11) and a guide roller (10) and a second guide element, preferably a second roller (12). A rope which is led between the guide rollers (10, 12) forms a loop (25) around the drive roller (11). The drive roller (11) can slide towards the guide roller (10). When a rope end (2, 13) is pulled, the rope is forced by the first guide roller (12) against the drive roller (11) to produce a strong working connection by friction which is preferably further enhanced by a peripheral V-shaped groove (22). The flanks of the groove (22) will advantageously have in addition an uneven surface, further improving the coupling between the drive roller (11) and rope (25). An appropriate arrangement of the guide rollers (10, 12) can ensure optimal wrap around the drive roller (11). A preferred use of the winch (8) is with rope hoisting and lowering devices, in particular when lifting heavy loads or persons.

摘要： To improve operating reliability and reduce rope wear, rope hoisting and lowering devices are provided with one or more novel features. One feature is the provision of an adapter (3) to which accessories (50) can be attached and preferably clipped. Possible accessories are retainers with eyes for attaching hooks and single- or multiple rollers for forming pulley blocks. The adapter in essence comprises a number of slit-like recesses in which are transversely interspersed rod-shaped retaining elements (11, 9). One of these retaining elements (9) can move to allow an accessory (50) to be attached or released. Another feature is the provision on the draw side of a rope stop (102). The rope (103) passes through the rope stop (102) and drives a knurled roller (110). The latter, when the rope reaches a certain speed in the descent direction, couples with a pivoting brake extension (118) via a centrifugal clutch. The rope (103) is then pinched and blocked between the extension (118) and a counterpart (108). A third feature is the provision of guide rollers (36, 37) to ensure that the rope follows a crosssover-free helical path.
