摘要

The support means (1) for vertical or inclined lifts has a worm screw (2) mounted in a guided transporting device and winds along on rollers (4) which are mounted to correspond to the screw pitch and with higher weight forces are located in closer order. The worm screw has a drive in the self-locking region and is always in engagement with at least one or more rollers. A mechanically operated control device is installed between a positive action clutch and the support means so that in the event of an emergency such as a power failure passengers can let themselves down to a lower stopping point.
