Abstract

Il comprend une roue libre à sens d'entraînement unidirectionnel intercalée entre l'arbre primaire et la roue de commande de la descente de la charge montée sur ledit arbre de manière à assurer l'accouplement automatique en cas de chute libre de la charge due à la position intermédiaire non embrayée du coulisseau d embrayage, le moteur d'entraînement de l'arbre primaire formant alors de par son régime ralentisseur de la chute. L'invention peut être utilisée pour tout type de treuil à commande par moteur.
