A method and device for determining the weight of a load while the load is being lifted by a lift or fork, typically in a lift-return cycle. Loadcell sensors are located close to the lift assembly with each loadcell sensor containing strain gauges attached to weigh posts to take measurements of forces acting in a multiple number of axes. The weight of the load can be calculated using these multi-axis measurements. The ratio of the forces acting in the different axes is used to correlate the measurements taken while the load is lifted and while the load is returned. The analog signals from the strain gauges are converted to digital signals by a analog-digital converter located in the loadcell sensor and transmitted to a computer which calculates the weight of the load with the use of a calibration table.

Cette invention concerne une méthode de pesée et un dispositif intégré à un mécanisme élévateur à fourche ou autre, la pesée se faisant généralement au cours d'un cycle de levage-abaissement de la charge. Des capteurs dynamométriques sont placés à proximité du mécanisme de levage, chaque capteur comportant des jauges de contrainte fixées à des barres de pesée et servant à mesurer les forces dans plusieurs axes. Le rapport entre les forces mesurées est utilisé pour corréler les mesures prises pendant la levée de la charge et pendant son abaissement. Les signaux analogiques livrés par les jauges de contrainte sont convertis en signaux numériques par un convertisseur analogique-numérique disposé dans le capteur dynamométrique et le résultat est transmis à un ordinateur qui calcule le poids de la charge à l'aide d'une table de référence.
