Abstract

a. Dispositif pour mesurer la charge d'appareils de levage; b. Dispositif de mesure de charge avec lequel la valeur mesurée influence un agencement de circuit électrique, caractérisé en ce qu'une jauge (au moins) de mesure d'allongement est fixée directement sur un dispositif de mesure qui est monté entre l'extrémité de l'organe de levage et un point fixe de l'appareil de levage, et est sollicité en allongement sous l'action de la charge; c. L'invention s'applique principalement aux mesures de charge pour des appareils de levage.
