Abstract

Un VGA de manutention de palette pouvant être utilisé pour récupérer et placer une palette à quadrants, comprenant une carrosserie de véhicule (1) et un châssis de lève-palette (2). Une roue motrice (3) est disposée sur l'extrémité inférieure de la carrosserie de véhicule (1). Un appareil d'entraînement entraînant la course et la direction de la roue motrice (3) est disposé dans la carrosserie de véhicule (1). Des roues porteuses (4) sont disposées sur l'extrémité arrière du châssis de lève-palette (2). Des roues de support centrales (6) sont disposées sur l'extrémité avant du châssis de lève-palette (2). Un portique intérieur (5) est disposé entre la carrosserie de véhicule (1) et le châssis de lève-palette (2). Le châssis de lève-palette (2) est relié mobile au portique intérieur (5). Un appareil de levage/abaissement entraînant le levage/l'abaissement du portique intérieur (5) est disposé dans le portique intérieur (5). Un mécanisme de liaison est disposé entre la carrosserie de véhicule (1) et le portique intérieur (5). Un mécanisme de liaison permettant au levage/abaissement du portique intérieur (5) d'être actionné simultanément à l'oscillation des roues porteuses (4) est disposé sur une extrémité sortie du mécanisme de liaison. Lorsque l'appareil de levage/abaissement amène le portique intérieur à être abaissé jusqu'à la position la plus basse, le châssis de lève-palette est abaissé jusqu'à la position la plus basse, les roues de support centrales sont supportées sur le sol, à ce moment l'état rencontré est un état sans charge et en attente de ramassage de marchandise ; dans cet état, le mécanisme de liaison amène l'ensemble roues porteuses à être complètement soulevé du sol d'une certaine hauteur ; par conséquent, lors de la récupération d'une palette à quadrants, les roues porteuses ne peuvent pas venir en butée transversale contre la partie inférieure de la palette, ni la gêner, ni se heurter à cette dernière.
