Cardinal already had a good truck scale with the EPR. Now they’ve improved it with the new EPR Plus Truck Scale.

Engineered with state-of-the-art robotics, Cardinal’s EPR+ Plus Truck Scale represents the culmination of 60 years of scale manufacturing experience. Available in impervious hydraulic or electronic load cell types, the EPR+ Plus’ durable baked-on, anti-corrosion powder paint stands the test of time. The legal-for-trade NTEP EPR+ Plus » Continue reading

You don’t have to look at too many truck scale brochures to become thoroughly confused about what’s available and what is and isn’t important to you.
Full-length truck scales may be of either portable or permanent installation.  Portable truck scales include a lower framework that is placed on a prepared surface (either a concrete slab, wooden beams, or even dirt) and ramps are placed at either end for access. Portable scales are generally more expensive because of the lower framework but are much easier to move from site to site and are ideal for contractors or road builders. Scales that are permanently mounted may be mounted either in a pit (like the basement of a home) or of an above-ground low profile design where the scale is mounted on a concrete slab with ramps at either end. The advantages of a pit type scale » Continue reading “New Truck Scales versus Used Truck Scales”

This month we continue looking at truck scale service.  This months topic is Load Cells. From a service perspective the overall procedure is to examine load cells and the area surrounding them. The load cell area may contain dirt and debris that has built up since the scale’s last check. Load cells must have clearance to deflect through their capacity range. The same debris that can bind the scale deck can also keep the load cells and suspension components from moving freely. » Continue reading “Load Cells”

Concentrated Load Capacity, or CLC, is an industry recognized rating of a vehicle or axle load scale. The rating defines the maximum load for which the weighbridge is designed as applied by a group of two axles with a center line spaced 4 feet apart and an axle width 8 feet apart. When a CLC load is applied to the weighbridge during a National Type Evaluation Program test, the NTEP tester records the displayed weight. If the scale falls within accepted testing tolerances, the scale has that CLC weight value recorded as the CLC on the Certificate of Conformance.

The CLC rating is not a measure of weighbridge strength or rigidity, because weighbridge deflection is not measured in the NTEP test. It is irrelevant if the load weighbridge sags 1/10th of an inch, or 10 inches, as long as the scale weighs within the accepted tolerance. The scale’s CLC weight rating passes in either case. A high CLC rating could be given to an extremely flexible deck sitting on load cell mounts which are capable of accurately handling the side loading resulting from a severely sagging weighbridge.

The Rice Lake SURVIVOR® truck scale line boasts a 45 ton (90,000 pounds) CLC rating. With most legal highway weight limits being a fraction of Rice Lake’s rating, owners of a SURVIVOR scale can expect a long lifespan through » Continue reading “What is concentrated load capacity and ntep?”
