Abstract

Camion du type trolley muni d'un pantographe monté sur le dessus du camion et d'un dispositif de commande (33) destiné à commander le pantographe, et se déplaçant à l'aide d'un mode trolley pour se déplacer au moyen de l'énergie obtenue depuis une ligne aérienne, et d'un mode non-trolley pour se déplacer sans obtenir d'énergie en provenance de la ligne aérienne. Le pantographe est muni d'un sous-châssis, d'un châssis inférieur fixé coulissant au sous-châssis, d'un châssis supérieur fixé coulissant au châssis inférieur, d'un frotteur (5) supporté par le châssis supérieur, et d'un dispositif à clavette destiné à fixer le châssis supérieur au sous-châssis lorsque le pantographe est plié. Le dispositif de commande commande le pantographe de manière à l'abaisser lorsqu'une commande d'abaissement de pantographe est entrée, et commande le dispositif à clavette de sorte que le pantographe soit immobilisé après rangement de ce dernier. En conséquence, il est possible de protéger et de commander le pantographe de manière à empêcher de façon certaine le pantographe monté sur le camion d'être endommagé ou de tomber en panne en raison de la déformation du pantographe.
