Abstract

The speed of travel of a lift cage is monitored by a shutdown device, comprising a cable-driven pulley with integrated ratchet wheel (4) and cam wheel. The cam wheel sets a rocker (5) with a rocker lug (5.21) into rocking movement. Rotatably mounted on the rocker (5) is an actuating lever (6.2) held in a rest position relative to the rocker by a restraining device (8) which may be a restoring spring, spring detent or a magnet. The upper end of the lever (6.2) is constructed as an actuating bracket (6.21) and its lower end as a tripping lug (6.22) projecting further than the rocker lug. Both lugs lie between two adjacent ratchet wheel teeth (4.1), when the roller (5.11) of the rocker stands on a cam lobe (3.1). When the roller (5.11) is between two cam lobes, the lugs are lifted out of the path of the teeth (4.1) and the teeth move past the lugs without effect. In the case of excess speed, the roller (5.11) lifts off the cam wheel (3). The tripping lug remains in the path of the ratchet wheel teeth. The next arriving tooth engages the tripping lug and deflects the lever (6.2), whereby the bracket (6.21) switches off the drive by way of a switch (9.1). On further rise in the speed, the rocker lug (5.21) enters the path of the ratchet wheel teeth (4.1) and leads to blocking of the cable pulley.
