Dynamic load weighing system

摘要

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.
