Abstract

L'invention concerne un système de transport pour le transport de conteneurs (2) comportant au moins deux robots de transport (1, 1a) qui sont conçus pour soulever et transporter ensemble un conteneur (2), les robots de transport (1, 1a) présentant au moins une unité de communication leur permettant de communiquer l'un avec l'autre, au moins un verrouillage (5, 5a) de coins des conteneurs, au moins une assistance (4, 4a) au couple de levage, et au moins deux châssis (8, 8a, 8b) munis d'un entraînement de roues (12). L'invention vise à proposer un système de transport et un procédé qui permettent un transport de conteneurs le plus rapide et le plus efficace possible. Cet objectif est atteint en ce que les deux ou plus de deux châssis (8, 8a, 8b) présentent chacun au moins une roue motrice (11, 11a) reliée à l'entraînement de roues (12), dont l'essieu peut pivoter autour d'un axe de rotation principal (17a) sensiblement vertical aussi bien dans un état non accouplé que dans un état accouplé au conteneur (2).
