ABSTRACT:
A pallet truck has a rigid frame mounting a plurality of load cells. Ball and socket coupling devices are connected to the load cells and support a platform assembly. The frame and platform assembly are able to be elevated to lift and support an object to be weighed on the platform assembly. The ball and socket coupling devices enable the platform assembly to shift laterally to dissipate lateral forces and then restore the platform assembly to a position wherein the weight of the object is transmitted along associated load axes of the load cells for accurately measuring the weight of the object.
