Abstract: The portable deck truck scale includes a deck structure which has a plurality of "V"-shaped support ribs extending between a bottom plate and an upper deck. The support ribs are configured to provide increased strength at the side portions of the deck structure, and the upper deck is either a metal plate or a concrete slab. If a metal plate forms the upper deck, the central portion is reinforced by spaced strips positioned over the side portions of the deck. When the deck is concrete, it has a thickness within the range of from 2 to 4 inches. This is achieved by adding silica fume and steel fibers to the concrete mix. The deck structure is supported on a load cell beam having a flat upper surface which supports the flat surface of a load button. An opposed radiused surface of the load button supports the flat end surface of a rocker pin which engages the deck structure.

Abstract: A weighing scale of the type utilizing a lever assembly to transfer a load from a weighing platform to a weight indicator by way of a suspension assembly interconnecting a platform load-transmitting beam to a lever of the lever assembly, with a suspension system having a pair of parallel rocker pins extending between the platform and a bearing member resting on a lever load pivot. The rocker pins have top ends which pivotally connect with the platform, and the pins extend downwardly to pivotally contact a pivot bearing member at their lower ends, so that the rocker pins move to accommodate any horizontal movement of the platform and isolate platform movement from the supporting bearing member. The rocker pins move, with respect to the bearing member, when the platform moves horizontally and the suspension assembly is designed so that those pins will abut the bearing member to control platform horizontal motion.
