What Type Of Scale Should A Metal Recycler Buy?

Another popular question we are asked is: How many types of 70 foot truck scales exist (low-profile, pit style, full electronic, concrete deck, steel deck)? Is there one particular type you would recommend over another for use within the recycling business? What benefit does it present to pick one over the other?

Truck scales come in numerous sizes and types. Truck scales could be portable axle, weigh-in-motion, self-contained transportable, electro-mechanical, electronic, and hydraulic versions. In a traditional truck scale you would need to choose either an above ground or pit style scale. Then, a painted steel deck or concrete deck that you would pour on location.

For the recycling business, generally the most effective choice will be the steel deck electronic truck scale because it provides the fastest setting up time and if you’re replacing an existing scale, the lowest down-time in swapping out a pre-existing truck scale. If the metal recycling company is replacing an older truck scale installed inside a pit that is experiencing water damage concerns, a hydraulic truck scale could be a good decision to think about for an advancement. The load cells within a hydraulic truck scale have excellent defense to water and lightning issues.

As with any big decision like this, we recommend that you contact your local scale company to provide you with a recommendation and truck scale price quote. It could be that your best choice might be a pit style scale. Or maybe a hydraulic scale would work best for you.  A local scale dealer should be able to provide that recommendation to you and present you with several buying options to consider.

It’s What’s Inside That Counts

Cardinal EPR What are some other features metal recyclers need to look for inside a truck scale?

There are several attributes recyclers ought to take into account when making the decision to purchase a 70 foot long truck scale, which includes deck plate thickness. Recyclers are normally handling a high traffic frequency daily on their truck scales, so weighing machine strength becomes a important aspect. For instance, Cardinal Scale produces truck scales with 3/8″ thick steel decks for maximum strength and resiliency to handle hefty loads over the long haul for exceptional overall performance. An additional quality element to look for is factory-assembled load cells secured in the truck scale. Every Cardinal truck scale is 100 percent factory assembled and examined prior to shipping to a job location. This requires calibrating the whole 60 foot long truck scale to make sure appropriate set-up before shipping for exceptional accuracy. Usually, a 70-foot-long truck scale dimensions are sought after in the recycling business to be in a position to allow for weighing semi-tractor trailers. Stainless steel, USA-made load cells and a NEMA 4X stainless steel junction box for load cell wiring can also be important to check for when making the decision to buy a vehicle scale.

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”®

It is Important To Learn As Much As You Can During The Initial Buying Stage

Built to Withstand Extreme Use
Weighbridge design and the overall weight of structural steel used directly affect the performance life of a truck scale. Many “economical” truck scale designs incorporate low grade, non-certified steel and an inferior design to reduce the cost and decrease production time. These reductions also reduce the life of the scale. Rice Lake SURVIVOR® OTR truck scales utilize up to 30% more steel than most competitive models and incorporate a longitudinal highway bridge design. More I-beams are strategically placed longitudinally with the traffic flow to ensure tire support regardless of truck position. Continue reading

Summer is almost here, Truck Scale Maintenance Ideas

We’re just about ready to head into the busy summer months. In a lot of cases, it is also a busy time for your truck scales. Spring is the best time to get the following maintenace done, because all the melting snow (in some areas) creating running water, mud and muck can wreak havoc on your truck scale operations; washing debris into pits and foundations, and damaging equipment. Not to mention the critters who have taken up residence over the long winter. We recommend completing the following steps in late spring to ensure you are up and running in time for the busy summer season. Continue reading

New Truck Scales versus Used Truck Scales

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

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. Continue reading

Checking Devices

As we continue to look at service of truck scales, this month we look at checking devices.  Some vehicle scales utilize suspension systems that don’t require checking devices, eliminating a time-consuming step in your service protocol.  If your scale has checking devices, make sure they are working properly.  Inspect check rods to make sure the attachment points are solid.  Check for binding.  If there is a problem, weight readings will be inconsistent from section to section.  Inspect hardware to ensure jam nuts are tight, rods are level and free of foreign material, and washers are not rusted or distorted.  Even if they are working properly, replace corroded hardware components so they don’t fail in the future when you least expect. Continue reading

Weighbridge for Truck Scales

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.

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
