Abstract: Platform weighing apparatus combines a foundation frame, a two layer platform, and interposed load cells of highly restricted vertical dimensions. The load cells are interfitted within cut-away portions of the underlayer of the platform, being removably attached to the platform, but floating with respect to the apparatus frame. Centering rings on the floating lower portions of the load cells facilitate set-up of the apparatus. The load cells lie wholly below the planar surface of the platform, facilitating attachment of hook-on ramps to the four sides of assembly to make it equally approachable from all sides. Deflectable bracing means prevent relative sideways motion of the platform and frame while permitting vertical weighing motion of the platform.
