Abstract

L'invention concerne une grue qui permet à un opérateur de sélectionner un trajet de transport approprié correspondant à une condition de fonctionnement. La plage de fonctionnement R d'une grue (1), qui est déterminée à partir du poids d'un colis W, est calculée. En tenant compte de la grue (1) disposée en une position représentée par des informations de position, il est déterminé si oui ou non la position de pointe d'une flèche télescopique (8) destinée à lever le colis W situé en une position de début de transport Pa et si la position de pointe de la flèche télescopique (8) destinée à abaisser le colis W situé en une position cible Pb sont comprises dans la plage de fonctionnement R. Une plage de transport possible Ra où un contact du colis W et de la flèche télescopique (8) avec une structure basée au sol S peut être évité est calculée à l'aide d'informations concernant la plage de fonctionnement R, d'informations concernant la forme du colis W, et des informations tridimensionnelles et des données 3D de la grue (1). En outre, un trajet de transport Rt qui satisfait aux conditions pour optimiser des paramètres facultatifs parmi les paramètres concernant le trajet de transport de l'emballage W de la position de début de transport Pa à la position cible Pb et les paramètres de la grue (1) concernant les opérations de transport sont calculés au sein de la plage de transport possible Ra.
