Abstract

Système de levage d'une charge à deux tambours fonctionnant en parallèle, synchronisés en rotation. Le système comprend un groupe moto-réducteur à deux pignons de sortie parallèles qui entraînent chacun un dispositif de levage relié à la charge par un câble. Un tel dispositif comprend une couronne dentée engrenant avec l'un des deux pignons de sortie, la couronne dentée entraînant, par un embrayage à friction comprenant un disque intermédiaire d'embrayage, un tambour de treuil sur lequel est attaché et enroulé le câble. Le disque intermédiaire comporte des cliquets de retenue interdisant sa rotation dans le sens correspondant à la descente de la charge, le tambour étant solidaire d'un arbre central dont la rotation dans le sens correspondant à la descente de la charge assure l'accouplement de l'embrayage. L'arbre central est synchronisé en rotation avec l'arbre central de l'autre dispositif de levage au moyen d'un accouplement à plateaux et disque d'accouplement muni de tenons ou rainures orthogonales, les deux arbres centraux étant supportés par un bâti fixe.
