ABSTRACT:
Wheel scale assemblies and load cell structures are provided for weighing loads. The invention provides a low profile portable wheel scale assembly of a predetermined height. The scale assembly has a thin lightweight base structure and a cooperating load platform. At least one load cell structure having strain gauges is in communication with the base structure and the load platform at predetermined locations and configurations. A platform support structure is provided to distribute the platform load. A unitary shear load cell structure contacts the weighing platform and provides a structural weight bearing component. The load cell structure has a unitary symmetrical load cell body. The load cell body has a centrally spanning elongated, deflectable beam structure. Opposing lateral indented beam portions form a central stress isolation web for the structural support and weighing of the load. Strain gauges are mounted in predetermined orientations to the parallel lateral beam walls. And, predetermined load cell configurations and arrangements are provided for low profile weighing scales.
