Abstract

La présente invention a pour objet un dispositif dynamométrique pour engin à flèche de levage Il montée rotative sur un châssis sous la commande d'un vérin 16 articulé à ladite flèche et audit châssis. Suivant l'invention, ce dispositif comporte un axe formant capteur de forces 20, qui sert de pivot entre le vérin 16 et la flèche 11, et qui porte deux jeux de jauges de contrainte propres, chacun respectivement, à la mesure de la composante de la force développée par le vérin 16 suivant deux directions orthogonales dont une fait un angle de 45 degrés avec une ligne repère choisie LR Application à la mesure du couple de renversement exercé sur la flèche d'un quelconque engin de levage par la charge appliquée à celle-ci.The present invention relates to a dynamometric device for a lifting jib machine II rotatably mounted on a frame under the control of a jack 16 articulated to said boom and to said frame. According to the invention, this device comprises an axis forming a force sensor 20, which serves as a pivot between the jack 16 and the boom 11, and which carries two sets of specific strain gauges, each respectively, to measure the component of the force developed by the jack 16 in two orthogonal directions, one of which forms an angle of 45 degrees with a chosen reference line LR Application to the measurement of the overturning torque exerted on the jib of any lifting device by the load applied to that -this.
