  • Method and apparatus for weighing a load
    Patent number: 5789714
    Abstract: This invention provides an apparatus and a method of using the apparatus to determine the weight of a load which is supported on a frame. In a preferred use of the invention, the load is supported on a tilt frame which is itself supported on the chassis of a transport means, such as truck.The apparatus of this invention comprises a combination of a hydraulic system for lifting the load and a load sensor for sensing the weight of the load lifted, wherein the full weight of the load to be weighed is simultaneously transferred to the load sensor as the hydraulic system lifts the load, while the entire load continues to be carried by the frame.The invention still further comprises electronic means for converting the sensed weight to digital terms and means for mathematically manipulating, storing, and displaying the sensed weight for immediate and subsequent purposes.
