Abstract

L’invention concerne des équipements de mesure et de pesage et peut s’utiliser dans différentes industries pour peser des objets mobiles dynamiques ou statiques, notamment des wagons de chemins de fer. L’invention permet de simplifier la conception d’une balance pour peser des objets ferroviaires mobiles statiques ou dynamiques, d’assurer une structure modulaire de ladite balance, d’éliminer les pièces intermédiaires de transfert de force dans la conception de balances de pesage, de simplifier le montage et l’entretien, et d’augmenter la précision du pesage. Selon l’invention, la balance pour peser des objets ferroviaires mobiles statiques ou dynamiques comprend un contrôleur de poids, un ordinateur et au moins une semelle de rail dont chacune est montée sur une traverse ferroviaire ShS-1 ou sur des pièces intermédiaires sur un socle en béton. Elle se distingue en ce que chaque semelle de rail joue en même temps le rôle d’une fixation du rail à la traverse ou aux pièces intermédiaires et le rôle d’un capteur de mesure de poids.
