Abstract

L'invention concerne un contrôleur d'état de charge notamment pour engin de levage. Ce contrôleur d'état de charge comprend un organe de calcul permettant de déterminer le poids de la charge suspendue au crochet de l'engin, un organe de mémoire dans lequel sont directement mises en mémoire les informations établies par le constructeur, ces abaques fournissant les valeurs de la charge maximale admissible, en fonction des valeurs d'au moins un paramètre définissant l'état de l'engin de levage, une unité centrale qui reçoit des informations des paramètres de la grue et qui determine la charge maximum admissible pour chacune desdites valeurs, cette unité centrale comparant ensuite la valeur de cette charge maximum admissible avec la valeur de la charge réelle de l'engin de levage. L'invention s'applique aux engins de levage.
