Title (EN) FREE FALL WINCH
(FR) TREUIL À CHUTE LIBRE
(DE) FREIFALLWINDE
Abstract:
(EN) The invention relates to a free fall winch comprising a drum, which can be rotationally driven by a winch drive, wherein a free fall brake is provided for braking the drum in free fall operation. According to the invention, a torque acting on the free fall winch, which depends on the free fall braking torque, is detected by means of a detection device, and a brake actuation force with which the free fall brake is actuated is controlled or adjusted by a control device according to the detected torque.
(FR) La présente invention concerne un treuil à chute libre comprenant un tambour, apte à être entraîné en rotation par un mécanisme d’entraînement de treuil, un frein de chute libre assurant le freinage du tambour en mode chute libre. Selon l’invention, un dispositif de détection permet de détecter un couple agissant sur le treuil à chute libre, lequel couple est fonction du couple de freinage en chute libre, et un dispositif de commande permet de commander ou d’adapter une force de réglage de freinage avec laquelle le frein de chute libre est actionné, en fonction du couple détecté.
(DE) Die vorliegende Erfindung betrifft eine Freifallwinde mit einer Trommel, die von einem Windenantrieb rotatorisch antreibbar ist, wobei eine Freifallbremse zum Abbremsen der Trommel im Freifallbetrieb vorgesehen ist. Erfindungsgemäß wird mittels einer Erfassungseinrichtung ein an der Freifallwinde wirkendes Drehmoment, das vom Freifallbremsmoment abhängt, erfasst und von einer Steuereinrichtung eine Bremsstellkraft, mit der die Freifallbremse betätigt wird, in Abhängigkeit des erfassten Drehmoments gesteuert bzw. angepasst.
