New Precast Concrete Scale Now Available

The Cardinal Harvester series precast concrete scales offer an economical approach to truck weighing for farms. The Harvester is a fully-electronic truck scale featuring factory poured concrete decks for above-ground, low-profile weighing. Incorporating the latest in patent-pending concrete composition with high tensile strength and optimal deck weight, the Harvester is designed for farms with 3,000 acres or less. Cardinal offers single-source convenience and quality construction utilizing USA-made stainless steel model CBC compression load cells.

Designed for light-duty agricultural weighing, the NTEP certified Harvester series of vehicle scales are the farmers’ choice for all types of vehicle weighing from planting to harvest. The Harvester’s low-profile design allows direct access to all scale components for ease of service. Clearance underneath the Harvester® truck scale’s weighbridge is 7.5 inches from the top of the pier to the bottom of the deck which allows plenty of room for washouts and easy access to the load cells. Bumper bolts allow for easy maintenance of the truck scale. Lateral checking is placed in the center of the scale to reduce bumper bolt adjustments due to expansion and contraction of the weighbridge from temperature change.

Survivor OTR

Rice Lake SURVIVOR® OTR vehicle scales are heavy-duty, top access, low profile concrete or steel deck scales. These heavy-duty, top access, low profile concrete or steel deck scales have an outstanding design that incorporates the most advanced engineering and production technology to produce the highest quality vehicle weighing system in the marketplace. The Rice Lake Survivor OTR truck scales don’t sacrifice quality for price. Both the OTR concrete and steel deck models boast wide flange I-beam construction. The wide flange beam construction helps minimize span deflection and lengthens the life of your truck scale. Both the concrete and steel deck models are built to be the “Toughest Truck Scales on Earth”®

Typical Installation Time for a OTR Survivor

When scheduling and planning installation for a typical three-module, 70′ Rice Lake Survivor OTR truck scale, plan for a minimum two-hour crane rental to place the modules into position. A two-man crew, aided by a crane operator, can usually unload modules from the freight truck and place them into position in approximately 1 hour.  Mount and load cell installation will require approximately 3 – 4 hours.  Electrical wiring is run through conduit and can be done in approximately 2 – 3 hours.

What is concentrated load capacity and ntep?

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

Cardinal Truck Scale Load Cell

Cardinal Truck Scale Load CellThe 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.

Steel or Concrete Weighbridge for Truck Scales?

The structural integrity of the truck scale weighbridge is the single most important consideration in the purchase of any truck scale. A failing weighbridge results in continuous problems that can only be solved with replacement. Rice Lake Weighing Systems standard model truck scales are comprised of beams spaced no further than 12 inches from center line or 8 inches from the edge of one flange to the next. This design ensures that a truck tire is on an I-beam at all times and never between.

Concrete Deck
While a concrete deck needs approximately 21 to 28 days to cure, it offers greater resistance to rust and corrosion from road salt and generally requires less maintenance than steel decks, helping to extend the life of the scale. A concrete surface also yields better traction with rain and snow. Because of their design, concrete decks distribute the load over a wider area than steel decks.  Rice Lake SURVIVOR® Series concrete deck truck scales are poured at the job site and typically have cure strength of 4,000 PSI at 28 days. The concrete is reinforced with steel rods and a minimum of two wide-flange main beams and seven wide-flange beams below. The Rice Continue reading
