Abstract

L'invention concerne une grue munie d'un limiteur de charge et de couple, en particulier une grue sur tour comportant une flèche articulée à la pointe du mât et sur laquelle peut rouler un chariot portant la charge tandis que la flèche est retenue par un câble de retenue et de dressage de flèche relié au chariot supérieur de la grue. Cette grue est remarquable en ce que le câble de dressage de flèche est relié à une poutre horizontale fixée par ses deux extrémités audit chariot supérieur et coopérant avec un interrupteur électrique de fin de course qui est actionné lorsque la poutre fléchit au delà d'une mesure prescrite de maniere à interrompre la manoeuvre de levage où l'avancement du chariot de charge.
