ABSTRACT:
A portable platform-scale weighing system comprises a floor dolly and lift mechanism that allow a heavy low-profile platform scale to be used practically anywhere truck cargoes need to be weighed. The low-profile platform scale includes a shear-beam load cell on each of four corners that are lifted off the ground by the lift mechanism whenever the dolly is being rolled to a new job. The weighing system puts weight on each of the shear-beam load cells only when the lift system has lowered the low-profile platform scale onto a protective outrigger runner on each side and such runners are resting on the ground. Such runners have turned up steel wings that prevent side impacts to the shear-beam load cells. Various guides and pins keep the low-profile platform scale centered over the floor dolly and lift mechanism so that when it is lowered it will drop properly on the two outrigger runners and minimize contact between the lift mechanism and dolly during the weight mode.
