LOAD WEIGHING SYSTEM FOR HEAVY MACHINERY

摘要

A structure which supports a device holding the material to be lifted is movable to locate the device in loaded and unloading positions. Apparatus for measuring the quantity of material delivered by the device comprises means to provide a processable position signal indicative of a determined position of the device, means to produce a processable load signal indicative of the determined load at a location within the structure, and processing means to receive the position and load signals for a plurality of interval determinations and calculate therefrom a number of weight determinations of the device and device contents, to select a sample of less than all of the weight determinations based upon the dynamic influences on the machine when the signals are processed, and to average the sample of selected weight determinations to provide a final weight determination of the device and device contents.
