Cardinal Scale’s Guardian® Hydraulic Truck Scales

Cardinal Scale’s Guardian® truck scales with hydraulic load cells are the smart choice for demanding applications like rock quarries, mining, sand and gravel plants, fracking, and heavy construction. Damage resulting from water, lightning and voltage surges, corrosion, rodents, shock loading, and extreme climatic conditions can dramatically increase the cost of ownership for your truck scale. Guardian® hydraulic load cells are covered under a true lifetime warranty against all of these issues protecting your investment.

Cardinal Scale’s Guardian Truck Scales

Cardinal Scale manufactures their own stainless steel, IP68-rated, 75,000-lb capacity Guardian® hydraulic load cells for their truck scales. These SST75 load cells carry a true lifetime warranty when installed in a Cardinal truck scale by an authorized Cardinal Scale dealer. They offer the highest level of protection possible against many of the conditions that adversely affect truck scales. Guardian® load cells can even operate fully submerged underwater.

Guardian® steel deck weighbridges utilize a tight concentration of 7.5-inch I-beam spacing which minimizes unsupported deck plate area and ensures that truck tire contact patches are always directly supported by one I-beam. This superior structural integrity provides a high 50-ton concentrated load capacity for heavy vehicle weights. The structural steel is shot blasted to an SSPC-SP10 condition to remove rust and mill scale, then protected with a baked-on, heavy-duty polyester anticorrosion tan powder paint for the highest quality and durable finish.
