   PATENT-ANSPRÜCHE :
1. Zwangläufig gesteuertes Gesperre für Hemmvorrichtungen an Hebezeugen, bei denen ein Sperrad   während   des Hebens der Last mit der Antriebsachse durch Reibung gekuppelt und daher gedreht wird, wogegen es beim Rückdrehen der Antriebsachse zuverlässig festgehalten und ein Senken der Last nur durch Lockern der Reibungskupplung ermöglicht werden soll, dadurch gekennzeichnet, dass mit dem Sperrade zwei Sperrklinkenarme zusammenarbeiten, die sich gegenseitig so steuern, dass immer mindestens einer der beiden Sperrklinkenarme mit dem Sperrade zuverlässig in Eingriff steht bzw. dass beim Ausrücken des einen Armes durch einen Zahn des Sperrades der andere Sperrklinkenarm in eine   Zahnlücke   des Sperrades eingerückt werden muss und umgekehrt, wobei die Zähne des Sperrades bzw.

   seine Zahnlücken so geformt und ausgeteilt sind, dass jeder Sperrzahn des Sperrades unter dem Sperrklinkenarm, den er jeweilig ausrückt, knapp durchleiten kann, ehe das Ausrücken des zweiten, eben eingerückten Sperrklinkenarmes beginnt.

   PATENT CLAIMS:
1. Compulsorily controlled locking mechanism for locking devices on hoists, in which a ratchet wheel is friction-coupled with the drive axle while the load is being lifted and is therefore rotated, whereas it is reliably held when the drive axle is turned back and the load can only be lowered by loosening the friction clutch should, characterized in that two ratchet arms cooperate with the ratchet, which control each other so that at least one of the two ratchet arms is always reliably in engagement with the ratchet or that when one arm is disengaged by a tooth of the ratchet arm in a tooth gap of the ratchet wheel has to be engaged and vice versa, whereby the teeth of the ratchet wheel resp.

   its tooth gaps are shaped and distributed in such a way that each ratchet tooth of the ratchet wheel can just pass through under the ratchet arm, which it disengages, before the disengagement of the second, just engaged ratchet arm begins.

2. Gesperre nach Anspruch 1, dadurch gekennzeichnet, dass jeder Sperrklinkcnami für sich gelagert ist und die gegenseitige Steuerung durch entsprechende Übertragungselemente vermittelt wird. 2. locking mechanism according to claim 1, characterized in that each Sperrklinkcnami is stored for itself and the mutual control is conveyed by corresponding transmission elements. 3. Gesperre nach Anspruch 1, dadurch gekennzeichnet, dass die beiden Sperrklinkenarn1t' miteinander starr verbunden und gemeinsam auf einer Achse gelagert sind. 3. locking mechanism according to claim 1, characterized in that the two locking latches' are rigidly connected to one another and are jointly mounted on an axle.
