The massively constructed, heavy steel weighbridge of Cardinal’s American-made RSCA railroad scale is stabilized laterally with checkrods and other specially designed restraints. Weighrails are sealed into the platform. Special design techniques and manufacturing procedures prevent excessive dirt, moisture and foreign material from entering the pit, providing this rugged electronic scale accuracy, dependability and exceptionally long life. The unique weighbridge design prevents lateral forces, caused from rail traffic going on and off the platform, from being transmitted to the load cells. NTEP legal-for-trade.
