  • Patent number: 4981186
    Abstract: A method and apparatus for load weight determination of the truck including the steps of loading the truck, sensing the pressure of the tilting cylinders to determine the amount of load, indicating the load weight, providing feedback on the affect of variations in the center of gravity of load to correct the load weight determined and providing a corrected load weight. The apparatus includes a tilting bed truck with the bed hinged to the truck frame and tilted to its dumping position by tilting cylinders, a sensing device for sensing the pressure in the tilting cylinders when they are supporting the bed above its support pad, a data processor having data on truck loading and receiving information on the pressure sensed by the sensing device and having an output to indicating devices of the load weight.
