Abstract

L'invention a pour but de réaliser une grue pour conteneurs d'un poids léger, tout en réduisant la durée de manipulation de la charge. Un chariot formant un relais central (60), faisant partie des trois chariots circulant sur des flèches (31, 32), comporte un berceau (61) sur lequel sont placés des conteneurs, par l'intermédiaire de leurs appareils de levage respectifs (42, 46), sur des chariots (41, 45) prévus des deux côtés. Le berceau (61) est maintenu en suspension à partir du chariot (60), avec une longueur de câble (62). La dépose au sol s'effectue en suspendant un conteneur au moyen du chariot (45) et en plaçant celui-ci sur le berceau (61). Le conteneur sur le chariot (61) est soulevé par le chariot (41) et abaissé côté sol. La hauteur du berceau (61) est basée sur le niveau minimum où le chariot (45) peut se déplacer avec le conteneur suspendu. Au fur et à mesure que les charges sont déchargées, le niveau du berceau (61) s'abaisse progressivement. Lorsque le chargement s'effectue, le niveau du berceau (61) s'élève progressivement. Une poutre auxiliaire (37) sur laquelle se déplace le chariot (60), est disposée côté sol d'une jonction d'une barre de traction (28) et de la poutre (32).
