Full-size, pit-type scales designed for weighing the heaviest of loads. The A.A.R.'s reinforced, live, concrete deck with recessed rails allows railcars and trucks to be weighed on the same scale. These scales meet or exceed all structural, sectional and accuracy requirements of the Association of American Railroads and Cooper E80, so extra-heavy railcars and locomotives can pass directly over the scale with complete safety.
