ABSTRACT:
The invention provides a portable wheel scale assembly which comprises a lightweight, low profile housing structure having an interiorly disposed opening with a bottom surface. The housing structure has opposing parallel bearing surfaces therein and at least one load cell assembly with strain gauges. The load cell assembly further has opposing bearings for engaging the bearing surfaces in the housing and it is constructed and arranged to directly receive a load force at a predetermined area. A load cell retaining structure having vertically movable flexible members is provided for restraining the lateral movement of the load cell within the wheel scale housing and for placing a minimum pre-load force on the load cell. The load cell retaining structure is further constructed and arranged to have opposing rigid securement members to restrain the movement of the load cell bearings on the bearing surfaces within the scale housing. The wheel platform member of the scale assembly communicates with both the load cell assembly and the vertically movable flexible members of the load cell retaining structure and it further cooperates with the load cell assembly to form a structural component of the scale assembly.
