Abstract

L'invention a pour objet un système de commande (10) destiné à un appareil de levage de charges d'un véhicule, ledit système commandant le fonctionnement d'un dispositif d'entraînement de l'élévateur, et ce en réponse aux commandes de l'opérateur et après interrogation d'un certain nombre d'états du véhicule. Parmi ces derniers figurent la position de l'appareil de levage de charges telle que déterminée par des détecteurs de limite, l'un inférieur (21) et l'autre supérieur (22), et l'état des actionneurs pouvant être manipulés par l'opérateur. En cas de dysfonctionnement ou d'un état inapproprié du véhicule, le fonctionnement du dispositif d'entraînement de l'élévateur est bloqué. Suite à un dysfonctionnement, un signal de désactivation peut être émis pour arrêter le moteur. Les autres états surveillés par le système comprennent la position (27) du frein à main, la transmission au point mort (26), le mouvement du véhicule (25) et la disponibilité d'une puissance supplémentaire (23). On a conçu des sorties (73, 74, 75) sous la forme d'alertes audibles et/ou visuelles. Le système logique se présente comme des circuits intégrés (40).
