<p>A hydraulic lifting and weighing system particularly for refuse collection vehicles and the like and includes means for dynamically weighing garbage. The system includes a hydraulic actuator operable to move a lifting arm and takes two measurements of the pressure of the hydraulic fluid in the system as the arm raises a waste bin whose weight is to be measured. The weight of the bin is calculated by multiplying the pressure by a factor determined by calibration with known weights. Weights are calculated based on the measurements of pressure and the result averaged. The system compensates for variations in hydraulic flow characteristics. The system includes means for compensating for variations in the inclination of the vehicle.</p> |
