    PATENT CLAIMS:
1. Safety device against excessive speed of the motors electrically operated hoists, characterized by an eddy current brake (w), whose excitation circuit is closed by the centrifugal governor (c) if the speed is too high.

Claims (1)

2. Anordnung nach Anspruch 1, gekennzeichnet durch mehrere Schalter, bezw. einen Stufenschalter (z 1') im Erregerstromkreise der Wirbelstrombremse (w), bei solcher Schaltung, dass eine stufenweise Wirkung der Wirbelstrombremse eintritt. 2. Arrangement according to claim 1, characterized by several switches, respectively. a step switch (z 1 ') in the excitation circuit of the eddy current brake (w), with such a circuit that the eddy current brake takes effect in stages. 3. Ausführungsform nach Anspruch 1, gekennzeichnet durch eine derartige Verbindung von Schaltern (z, s), die nacheinander von dem Fliehkraftregler (c) betätigt werden, dass zunächst die Wirbelstrombremse (tu,), und bei etwa noch steigender Geschwindigkeit eine elektromagnetische Haltebremse (e) in Wirkung tritt. 3. Embodiment according to claim 1, characterized by such a connection of switches (z, s), which are operated one after the other by the centrifugal governor (c), that first the eddy current brake (tu,), and at approximately still increasing speed an electromagnetic holding brake ( e) comes into effect.
