Un camion-benne comprend : une plate-forme de transport (3) destinée à transporter un objet de transport; une carrosserie de véhicule (1) qui supporte la plate-forme de transport de manière inclinable; un dispositif de détection du poids (10) qui détecte le poids transporté de la plate-forme de transport; une unité de traitement de commande (11) qui effectue un processus se rapportant au poids transporté de la plate-forme de transport à l'aide d'un signal de détection provenant du dispositif de détection du poids en tant qu'entrée; et un moniteur (19) qui affiche le poids transporté de la plate-forme de transport. L'unité de traitement de commande affiche le poids transporté de la plate-forme de transport sur le moniteur sur la base du signal de détection provenant du dispositif de détection du poids pendant une opération de chargement du camion-benne et, lorsqu'il est déterminé que l'opération de chargement du camion-benne est terminée, finalise la valeur du poids transporté qui est affichée sur le moniteur et met en œuvre une commande pour arrêter une mise à jour ultérieure de l'affichage du poids transporté.
