Hydraulic loads cells are the most rugged and long-lasting weighing device available in the scale market. Cardinal’s extensive truck scale experience has culminated in developing The Guardian Hydraulic Truck Scale. Hydraulic Tuck Scales are ideal for the solid waste, aggregate, chemical, grain, and construction industries because they offer a high level of protection against many of the conditions that can adversely affect truck scale installations. Water, lightning, power surges, explosive areas, corrosion, welding, shock loading, extreme temperature fluctuations and even rodents can cause scale problems, all at a cost to the owner. Cardinal's Guardian Hydraulic Truck Scale provides a superior level of performance. We also offer Electronic Above Ground scales and Pit scales.
