ABSTRACT:
A securing system is provided for securing a central, load-supporting, movable platform to a fixed peripheral framework base of a weigh scale, in a torque arm mounting for weigh scales. The securing system includes at least one securing element disposed between the central inner movable load-supporting platform constituted by inner upper and inner lower platforms, between the outer lower frame member and the fixed peripheral mounting frame. Aligned-through holes pass through the central inner lower platform and the outer lower frame member. A dead-end cylindrical bore extends from the upper face of the inner upper platform. A compression spring is seated within such dead-end cylindrical bore. A hole pierces the bottom of the dead-end cylindrical bore. A third aligned through-hole passes through the compression spring. A securing bolt extends concentrically through the three aligned through-holes, and the compression spring and is threadably secured to the mounting frame.
