Abstract

Abstract Translated from French Dispositif de contrôle automatique de la position et des oscillations d'une charge suspendue durant son transfert par un appareil de levage comprenant : - au moins un moyen de guidage sur lequel se dépla­ce un chariot mobile en translation actionné par un moteur, auquel est accroché un câble (ou une tige) à l'autre extrémité duquel (de laquelle) est suspendue la charge à transférer ; - au moins un capteur de position, - un capteur angulaire, disposé sur le chariot, caractérisé en ce qu'il comprend : - une première boucle d'asservissement comprenant : . un premier comparateur (22) . un correcteur proportionnel (23) - une seconde boucle d'asservissement dite de posi­tion, comprenant : . un second comparateur (20) . un correcteur proportionnel et intégral (21) - un sommateur (24). Device for automatic control of the position and oscillations of a suspended load during its transfer by a lifting device comprising: - At least one guide means on which moves a mobile carriage in translation actuated by a motor, to which is hung a cable (or a rod) at the other end of which (from which) the load to be transferred is suspended; - at least one position sensor, - an angular sensor, placed on the carriage, characterized in that it comprises: - a first control loop comprising: . a first comparator (22) . a proportional corrector (23) - a second so-called position control loop, comprising: . a second comparator (20) . a proportional and integral corrector (21) - a summator (24). Application : tout transfert de charge suspendue requé­rant des conditions particulières. Application: any transfer of suspended load requiring special conditions.
