ABSTRACT:
A low profile weighing scale for weighing and balancing aircraft and land vehicles. The electronic, strong, lightweight, economical and portable scale provides accurate and reliable results. The scale comprises: (a) a quadrilateral base having two sides and two ends, the base further having recessed load cell mounts, each load cell mount having a strain cavity disposed between two support positions, each support position having a threaded mounting screw aperture for reception of a mounting screw; (b) double ended shear beam load cells, each end of each load cell being mounted to a support position by a mounting screw; (c) a platform having a non-skid top surface for contact with a load and a bottom surface, the bottom surface having load cell recesses sized and aligned with the load cells, each load cell recess having an engagement surface; and (d) engagement members, each comprised of a load bearing, for moveably mating the platform to the load cells and effectively transferring a load force from the platform to the load cells, each load cell having a cupped surface for receiving a load bearing, load ball bearing being in simultaneous operational contact with a concave engagement surface on the platform. The design of the scale effectively and accurately distributes a load force applied to the platform through the engagement members to the load cells.
