Abstract
Weight sensors coupled to the bed of a conventional haulage truck measure the weight applied to each tire strut as the truck is being loaded. Based on the weight applied to each strut, the exact position of the center of gravity of the load in the truck's bed is calculated and displayed on a monitor relative to a target position deemed optimal for uniform weight distribution. Based on this information, the operator of the loading machine can complete the loading operation in such a way as to shift the center of gravity toward the chosen target position. In another embodiment of the invention, an automated algorithm calculates and displays where the next bucket load should be dropped, based on its approximate weight, in order to shift the center of gravity toward the target location.
