ABSTRACT:
A weighing system for determining the weight of material deposited from a container into a collection truck for collecting refuse or recyclable material includes at least one load cell installed into a lifting fork of the truck lifting arm for producing output signals based on the load on the arm as the full container is lifted and the emptied container is lowered. An acceleration or angle sensor is also provided on the lifting arm for sensing the acceleration or angle of the arm and producing a corresponding output signal. A processing unit receives the load cell and sensor outputs during raising and lowering of the lifting arm, and calculates the dynamic weight of the refuse lifted and deposited from the container, using the sensor output to compensate for the angle or G forces on the arm.
