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. A rock-solid, checkered steel deck plate is standard and available with several options for lengths and capacities. NTEP legal-for-trade certified.
