Cardinal's PRL Series heavy duty, self-contained mechanical truck scales are made for endurance and accuracy, while remaining completely self-contained. Tandem units are simply composed of two or more scales of the same or different platform lengths tandem-connected for greater capacity. When split, each unit is a self-contained scale in itself, offering 3-in-1 scale flexibility. The tandem connecting system is simple and patented. Scale sections bolt together quickly for installation or later lengthening of the scale.

The 5/16" full checkered steel deck plate is standard and keeps debris from falling into the scale mechanism. An optional wood deck is also available (see PSRL models below).
