ABSTRACT:
Accurately measuring the payload weight of dump trucks, especially off highway trucks, is important to efficient operation of most applications, such as in the mining industry. An under-loaded truck decreases efficiency in a known manner. In addition, over-loading a truck can decrease efficiency in the long run by such things as shortening truck component life due to excessive wear, such as on the drive train. The present invention seeks a more accurate payload measurement by positioning the dump body between its travel position and its dumping position. In the payload measuring position, the dump body is supported at four points, which are preferably pins equipped with shear strain gauges. After measuring the payload weight, the dump body is returned to its travel position for transport.
