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.
