Now that you’ve bought a truck scale, completed the foundation, have the scale installed, what’s next?  Before your truck scale can be used for obtaining weight measurements, it must first be calibrated to your digital weight indicator and approved by your state. Your local scale service company will take care of this by bringing their test truck to the scale test site. The test truck holds certified calibrated test weights that are placed on the scale platform for testing and calibration. The test » Continue reading “Calibration of a Truck Scale”

Closed-bottom weighbridge designs with both top and bottom plates, typically using lighter weight components, create cavities that tend to hold moisture causing rusting of internal components. Rice Lake’s SURVIVOR® steel deck truck scales feature an open-bottom design providing unrestricted airflow eliminating rust causing moisture buildup which accelerates rusting of internal steel and imminent scale failure.

According to Handbook 44, all approaches for any type of NTEP-certified, legal-for-trade truck scales shall be 10′ long, flat, level, the width of the scale and constructed of concrete. The ramps plus the approach must be at least half as long as the scale, but no more than 40′. » Continue reading “Ramps and Approaches”

A proper foundation is one of the most important parts of your truck scale. If the foundation is not constructed properly, built flat and level, or according to the certified foundation drawing, your truck scale foundation could shift and bring the scale out of accepted calibration tolerance. If the movement continues, your scale will become inoperable and require costly foundation repairs. Many factors must be considered in the process, such as the slope of the site and soil conditions. Below are a few other factors that must be taken into consideration. The SURVIVOR® truck scale line’s quality design and engineering is further complemented by Rice Lake’s ability to » Continue reading “The foundation for success”

It is probably a good idea to have your heavy capacity truck scales checked at least every six months at a minimum. Also, a convenient time to conduct a preventative maintenance scale inspection is during the regularly scheduled calibration check.  It’s a good idea to inspect your truck scale just prior to peak usage times, such as harvest season in agricultural operations.

Cardinal Scale’s truck scale manufacturing processes was featured in a Fall 2008 episode of cable TV’s popular program “How It’s Made” airing on the Science Channel. The segment details the production of a 70-foot-long electronic Cardinal truck scale. Beginning on a microscopic level with the creation of the strain gauges that reside in the scale’s load cells, the educational program charts the manufacturing course of a Cardinal model EPR truck scale. It proceeds to show the welding processes involved in the steel tubing and load cell stands, the powder paint process, and final assembly where the finished truck scale is shown with test weights being applied to measure its superb accuracy.

The episode first aired in November 2008 and will be translated into over 3 dozen different languages to be shown internationally. One of the reasons Cardinal was asked to participate on the show was worldwide brand name » Continue reading “Cardinal Truck Scale Manufacturing”

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?”

Cardinal’s 225 Navigator features transflective technology which allows the 225’s display to be viewed under any lighting conditions from direct sunlight to total darkness. One-inch-high (25 mm) weight characters make viewing easy. View up to 3 scales with total weight simultaneously with the optional dual scale input board; no special software is needed with Cardinal 225 Navigator digital weight indicator.

Entering, viewing, and storing truck names is easy with the 225 Navigator’s convenient Truck ID menu.  Complete alphanumeric descriptions for truck and material prompts make storing and recalling tare weight values quick and simple.

The heavy capacity series of compression load cells are ideal for multiple load cell compression applications such as motor truck scales, railroad track scales and heavy duty tank weighing systems. These compression load cells are available in 50K-SCA 22680kg, 100K-SCA 45360 kg and 120K-SCA 54430 kg.

Cardinal SCA Truck Scale Load cells are fabricated from stainless steel to provide the ultimate in protection when caustic, corrosive or wet environments are encountered. Load cells are hermetically sealed for absolute water protection (IP68). Each load cell is furnished with stainless steel load buttons on each end, and a 9m integral multiconductor cable secured by a strain relief seal.
