A motion control system for hydraulically operated lifting devices. The system provides for the dynamic weighing of a loaded container by controllably directing hydraulic flow through a bypass chamber (51) of a two-way valve (42). An analog output signal is generated by a hydraulic pressure transducer (53) fluidly communicating with the two-way valve or by a tensiometer (24) mounted on the arms of the lifting device (14). The two-way valve (42) further provides a second bypass chamber (54) which receives fluid under gravity from the lift circuit line (40) of the hydraulic cylinder (18) for controllably lowering the lifting device (14). The pressure transducer (53) or tensiometer (24) generate an analog signal proportionate to the weight being lowered and whereby the hydraulic fluid is returned to the reservoir of the hydraulic system independently and downstream of the main operating valve (33).
Système de commande de mouvement pour dispositifs de levage à fonctionnement hydraulique. Ledit système permet la pesée dynamique d'un conteneur chargé en dirigeant par commande le flux hydraulique à travers une chambre de dérivation (51) d'une soupape ordinaire (42). Un signal de sortie analogique est généré par un transducteur de pression hydraulique (53) communiquant par l'intermédiaire du liquide avec la soupape ordinaire ou par un dynamomètre de traction (24) monté sur les bras du dispositif de levage (14). Ladite soupape ordinaire (42) comporte en outre une seconde chambre de dérivation (54) qui reçoit du liquide sous gravité provenant de la ligne du circuit de levage (40) du cylindre hydraulique (18) afin de faire baisser par commande le dispositif de levage (14). Le transducteur de pression (53) ou dynamomètre de traction (24) génère un signal analogique proportionnel au poids baissé, le liquide hydraulique étant renvoyé dans le réservoir du système hydraulique indépendamment et en aval de la soupape principale de fonctionnement (33).
