Abstract

La présente invention concerne un chargeur à grue permettant de traiter une grande quantité de charge sans accroître le coût de base. Une trémie (53) d'un chariot trémie (40) est placée en dessous d'un godet (30) d'une grue (10) polyvalente en forme de portique. Une des extrémités du chariot trémie (40) est suspendue à une poutre transversale au niveau de l'une des extrémités de la grue (10). L'autre extrémité du chariot trémie (40) est placée sur le rail de la grue (10) au moyen de roues extérieures à la grue (10). Des véhicules passent en dessous du chariot trémie (40). Le chariot trémie (40) se déplace avec la grue (10). Dans le cas où des conteneurs sont chargés sur un camion, chaque conteneur est installé à l'aide d'un cric faisant partie d'un des montants (41) de la grue; à cet effet, une connexion d'un dispositif de connexion est libérée. On charge des conteneurs dans un endroit où le chariot trémie (40) ne se trouve pas.
