Abstract

Un monte-charge comporte un dispositif d’entraînement disposé dans l’arbre du monte-charge. Le dispositif d’entraînement est doté d’une poulie d’entraînement rotative. Dans l’arbre du monte-charge, une roue de déviation est également disposée espacée de la poulie d’entraînement. Une corde principale sur laquelle sont suspendus une cage et un contrepoids passe par la poulie d’entraînement et la roue de déviation. Le dispositif d’entraînement et la roue de déviation sont agencés à l’extérieur de la région de la cage dans le plan de projection vertical de l’arbre du monte-charge. La superficie de la section horizontale de l’arbre du monte-charge peut être réduite en réglant les positions du dispositif d’entraînement et de la roue de déviation.
