The USA-made Cardinal’s PRL series of heavy-duty, self-contained mechanical truck scales are designed for durability and precision, while staying totally self-contained. Tandem units are basically composed of two or more scales of the identical or different platform sizes tandem-linked for superior capacity. When we split it, each unit becomes a self-contained scale in itself and offering 3-in-1 scale flexibility. PRL self-contained scale features a rock solid steel deck plate to lift heavy loads. There is a range of many capacities and lengths available to choose from.  These PRL self-contained scales are legal for trade certified by NTEP.
