Most Frequently Asked Questions About Truck Scales

Posted on by

Over the past few years, we have received numerous questions and inquiries about truck scales and vehicle weighing related items. So, we thought it would make a perfect article called Most Frequently Asked Questions About Truck Scales. Below is a summary of the top questions that we have received along with some basic answers to assist you.

What is a Truck Scale and How Exactly Does a Truck Scale Work?

Truck scales are industrial scales built to weigh vehicles. The most common use of a truck scale is to determine the weight of bulk goods being bought and/or sold. You may have seen this mentioned before but in many cases, a truck scale functions figuratively like a cash register for a company. In addition to commercial use, many states use truck scales to check for a truck’s compliance with truck weight limits. The vehicle scales are very popular at feedmills, solid waste processing and metal recycling centers, etc….

As for how a truck scale works, basically you start with a foundation. This is normally a concrete foundation that the truck scale will be anchored to. The actual scale platforms are anchored onto the foundation. There are usually multiple platform modules connected to make up a 70 foot long truck scale. Inside of these modules are load cells. These are the sensors that measure the weight when you drive up on the scale. These can be analog, digital or hydraulic. The weight is then displayed on the digital weight indicator.

how do truck scales work?

How Much does a Truck Scale Cost? Should I Buy a Used Truck Scale?

This is a question that we have tackled before! This number has changed obviously over the years. At the time of this article, the typical truck scale costs are probably near $75,000 or more when you factor in all the various expenses. Remember, this estimate can fluctuate. For example, there have been multiple price increases during the past twelve months.

Regarding used truck scales…. In most cases, we are against buying used truck scales. The reason is these are weighing devices that have 80,000 lb vehicles driven over them constantly and endure all that Mother Nature can throw at them…. year after year. A lot can happen to a truck scale that’s been in use out in the elements for an entire decade.

That being said, sure there might be some good deals on a “low mileage” or “hardly used” used truck scale, but in our opinion, the best long term decision is to buy a brand new truck scale that you hopefully will get to use for two or three decades.

What is the Average Life Span of a Truck Scale?

In our opinion, most truck scales should last around 25 years. However, a lot depends on choosing a quality scale and one that is matched to the amount of truck traffic you expect. Weather elements can also factor into longevity as well. This is where consulting with your truck scale sales person can be a huge benefit when shopping for a truck scale..

All things being equal, a truck scale that weighs a couple of hundred trucks a day is going to wear out quicker than a truck that only weighs a handful of trucks a day. This is an important question and one that you need to discuss with the scale company(s) that you are working with when shopping for a truck scale.

How Accurate is a Truck Scale?

If you buy or sell goods based on the weight of the truck scale, accuracy is critical. Profit, Inventory Levels, and much more are at stake! On a typical 120,000 x 20 lb capacity truck scale, we typically tell folks the accuracy of your truck scale should be somewhere in the neighborhood of 0.1 of one percent.

How Long is an Average Truck Scale?

Most folks weigh typical trucks with trailer. The majority of the time, that means a 70 x 11 truck scale is typical. However, we have seen 80 foot long truck scales or longer utilized. You want to make sure that you choose a vehicle scale that will allow you to get all the tires on the weighing platforms. This is an important subject to consider when choosing a truck scale.

What is a Load Cell & How Many do I Need?

A load cell is the item(s) in a truck scale that measure the weight being applied. Most truck scales require ~ 8 load cells. In most scales, the load cells are wired through the scale platform & summed together in a junction box.

What is a Junction Box?

A j-box is a box with a summing card inside. Usually anywhere from (4) to (8) load cells are connected to the summing card inside the junction box. The card can then be adjusted by the scale technician when calibrating the scale. The signals of multiple load cells are adjustable and then once they are fine tuned, are capable of being wired to the digital weight indicator via the homerun cable.

Should I Purchase a Steel Deck Truck Scale or a Concrete Deck Truck Scale?

Steel deck truck scales have a quick installation time (usually one day) and they are lighter weight. This also is a benefit if you ever need to move or sell the truck scale, years later.

Concrete deck truck scales have a much longer installation time overall since the concrete must cure. The scales are also much heavier which can make moving them or selling them more difficult. On the plus side, a concrete deck typically has better traction than a steel deck.

So, ultimately either choice of industrial scale can be a good one. It depends on what your particular needs are and what your future plans might be with the scale.

I Keep Reading About Lightening. How can I protect my truck scale from lightning?

Most truck scale manufacturers offer weighing scales with grounding and industry standard protection which in most cases involves a single point grounding system with surge protector. This is an ongoing area where manufacturers are working improve their products for better protection. We’ve seen better protection being introduced for load cells and summing boards for example.

How Much Truck Scale Service Maintenance is there? How Often Should I Calibrate a Truck Scale?

With an investment like a truck scale, it makes good sense to have the scale checked & calibrated on a regular basis. Generally, we suggest that truck scale owners have their scales checked anywhere from twice a year to four times a year. Also, the scale owner can do a few things as well throughout the year like keeping the scale underside clean and debris free since buildup under a truck scale is a very common problem.

Another to consider when determining calibration frequency is how many trucks per day are weighed on the scale and the dollar value of what you’re weighing. If your 120,000 pound capacity truck scale is off just a hundred pounds, it can mean thousands of dollars of profit loss and/or a safety hazard. So basically if your truck scale weighs a lot of trucks every day, then you should consider a regular quarterly calibration program with your scale company.

We hope this article helps you to make an intelligent scale purchase. The truth is, there are numerous scale companies located throughout the United States that employee very smart and talented scale professionals who can work with you to recommend a great scale for your weighing needs. As for the scale manufacturers, there are multiple high quality scale manufacturers in the United States who build very good truck scales.



Truck Scale Purchasing Decisions Guide

Posted on by

Anytime that you need to make a large investment, it’s only natural to ask a lot of questions. That is certainly true when it comes to purchasing a truck scale. Manufacturers and dealers are sure to hear all kinds of questions like…

What kind of truck scale do I really need?

What are the local requirements and environment that must be addressed for the application?

Which scale options would be most beneficial for the application in question?

Which type of construction would be best for the environment the truck scale will be used in?

Should the truck scale be installed in a pit that is flush mount with the road or include ramps and be installed above ground?

Which technological advancements will pose the best advantage for my application?  Things like hydraulic or digital load cells for example.

All of these questions must be taken into serious consideration to get the most out of truck scale longevity, maintain truck scale functionality, decrease downtime, and maximize the return on your investment.

Cardinal Scale Pit Type Truck Scale

Below is a portion of the truck scale purchasing decision guide by Cardinal Scale Manufacturing. This document will analyze strengths and limitations of options available on the market today, and which weighing technologies are the most appropriate in a given environment.

Concrete Deck Truck Scale
A concrete deck truck scale is ideal for environments where high levels of moisture and a corrosive environment are a concern. Scrap yards, trash dumps, transfer stations, chemical distribution centers, and grain elevators are ideal environments for concrete decks due to their likelihood of causing rust. Climates where road salt is frequently used may influence the purchase of a concrete deck to combat the corrosive effects of the salt.

Concrete decks yield a more reliable surface texture when in used slippery or snowy conditions. Concrete decks also distribute weight better, which gives them an advantage in applications that are of very high traffic. On average, they will require less maintenance over the life of the truck scale, and they will last longer than a steel deck truck scale.

Not without drawbacks, concrete deck truck scales are more expensive, require an initial curing period, and require some additional finishing work that a steel deck scale would not. Their mass is usually greater than that of a steel deck, which will make relocation of the deck more arduous if performed at a later date.

Steel Deck Truck Scale
Steel deck truck scales will cost less than concrete deck truck scales, eliminating the costs of labor associated with concrete pouring. Steel decks are much easier to install and can be functional within a day, saving much-needed time when production output is of the utmost importance.

Recent improvements in steel deck design provide a more robust weighbridge and less susceptibility to corrosion caused by moisture. Steel decks that utilize close-spaced, thicker I-beams and stiffeners ameliorate deflection caused by high-stress concentrations, i.e., bowing or dimpling. Minimal spacing between I-beams allows for greater CLC (Concentrated Load Capacity), a load rating which measures maximum load capacity in a moderately small area of the scale platform. Steel decks that feature an open-bottom underside prevent moisture build-up, thus alleviating one cause of deck corrosion.

Despite these improvements, steel decks still have more issues with moisture in comparison to concrete decks. They tend to be more slippery in wet environments and are more disposed to corrosion. Because of their inclination to corrode, steel deck truck scales require more maintenance and tend to have a shorter service lifespan if not properly monitored and cared for.

Electronic Truck Scales
Electronic truck scales are the most common type of truck scale available on the market. This type of truck scale accumulates electrical signals, which are derived from analog strain gauge load cells and summed up in a junction box, combining signals from each individual load cell. These summed signals are then fed from the junction box into an indicator and converted into a digital value displayed for the customer to view. Analog load cells come in many variations, but the two most common types of load cells for truck scales are the compression load cell and shear beam load cell.

An electronic truck scale system employing analog load cells has some distinct advantages. Analog load cells are inexpensive and have been on the market for a relatively long period. There are many variations of analog cells that are available, and they have a fairly wide range of weight capacities.

Analog load cells have many drawbacks, however. Analog load cells, because of their construction and electrical characteristics, are especially sensitive to lightning damage. When a 70-foot-long piece of steel is placed in the middle of a field, like a truck scale platform used in a trash dump, it becomes a lightning rod that is very susceptible to lightning strikes. Suppression circuitry is added to the overall wiring to divert extreme lightning current from the strain gauges. However, this does not prevent load cells from being destroyed by lightning and require replacement by a trained scale service technician.

Analog load cells can be prone to moisture ingress. Internal circuitry can be compromised easily, leading to unstable readings, inoperable cells, or a completely defective system overall.

Hydraulic Truck Scales
Hydraulic truck scale systems operate on the same information transfer system, but the elicited signal is triggered by a different source, and the respective signals are combined by stacking pressure actuators or combining pressure transducers. In the transducer method, hydraulic load cells utilize hydraulic fluid to transmit force applied to the scale weighbridge to pressure transducers, converting that force into an electrical signal. This process operates solely on hydraulic pressure, meaning no electrical components are used in the scale weighbridge.

Hydraulic truck scale systems perform extremely well in moist environments, and they don’t experience many issues regarding lightning damage. Hydraulic truck scale systems do not have the onus of strain gauges or internal circuitry, allowing for superior capability in the aforementioned environment. A system based on this type of technology is more expensive than analog cells; however, this increased cost can offset the issues analog systems experience regarding lightning and water and create a lower cost of overall ownership over the lifespan of the hydraulic truck scale.

Digital Truck Scales
Digital truck scale systems produce a digital output signal, performing the analog-to-digital conversion in the load cell itself. This important distinction precludes signal degradation associated with analog cells. Digital load cell systems are much easier to manage due to the lack of a junction box and its associated wiring requirements. Digital load cells can be simply linked to one another in a daisy chain.

Digital truck scale systems, because of their simple design, are very easy to install, maintain, and repair. Since the load cells are more reliable and accurate, costs associated with diagnosis are decreased. Digital truck scale systems have the capability of detecting and diagnosing faults and failures more quickly, efficiently, and precisely.

Digital load cells also offer the highest protection against lightning strikes among electronic load cells due to the transient suppression circuitry that is located directly on each individual digital load cell.

Summing it all up, truck scale construction and technologies are a pretty broad range of choices. Often, the overall cost of ownership can be lowered by purchasing a higher quality hydraulic or digital truck scale that will offer more competitive features than a lower cost traditional analog truck scale. Taking these factors into consideration will improve your overall experience and satisfaction with your truck scale purchase.

Cardinal Pit-Mounted Truck Scales Provide Port of Miami Ability to Weigh Greater Volume of Freight

Posted on by

Two Additional Cardinal Scale Pit-Mounted EPR Truck Scales Provide Terminal the Ability to Weigh Greater Volumes of Freight. Major ocean transport company adds more Cardinal EPR truck scales and 210 indicators to expedite traffic flow for 600 truck weighments per day at busy Port of Miami.

Traffic congestion was becoming a major issue at the Port of Miami with a steady increase in export freight volumes over the last several years and the completion of a new underground truck tunnel leading into the port. A lengthy line of trucks were typically waiting to be weighed before entering the freight terminals at the port.

It became apparent that a solution was needed to be able to move this increased traffic through the port more quickly and efficiently.

 

Cardinal Scale Pit Type Truck Scale

One of the largest ocean transport companies at the Port of Miami rearranged their container yard and came to Cardinal Scale seeking a solution for its truck scale needs.

Cardinal Scale had several meetings with Port of Miami officials and the ocean transport company’s personnel during which various yard and scale layouts were considered, including above or below ground scales, steel or concrete decks, network connectivity, and weight documentation.

It was ultimately decided that there would be two new inbound steel deck truck scales installed below grade in deep pits. The deep pit request presented an important challenge: How to ensure that a 4 1/2 foot deep pit would remain dry at just above sea level on an island?

Cardinal Scale had stressed the importance of keeping the pit dry during the design process.

Therefore, the ocean transport company contracted with an engineering company that designed and built an elaborate self-contained underground pump station, which was built adjacent to both scale pits to prevent the pits from flooding.

The ocean transport company decided to purchase two new 13570-EPR truck scales from Cardinal Scale, which were slightly modified to be installed in the pits. The pit design was chosen to save yard space, as well as, producing an easier and safer method for drivers and other personnel to move in and around the trucks. A steel deck was chosen over a concrete deck to avoid delays associated with the curing time of a concrete deck.

The scales were connected to Cardinal Scale model 210 weight indicators fitted with 10/100 Ethernet cards and attached to P500 receipt printers, which were installed in two separate scale houses. The Ethernet cards allow them to communicate the weight data to their remote server and the ticket printers allow them to produce a hard copy for the truck drivers, which not only includes their truck ID, but the time and date of weighment as well.

The ocean transport company’s freight terminal at the Port of Miami operates 24/7, 365 days a year.

It can now weigh more than 600 trucks per day with the addition of the two pit-mounted Cardinal truck scales. The ocean transport company has substantially reduced the weigh-in time for each truck, which in turn allows them to load the freight containers on the cargo ships more efficiently.

The additional truck weighing scales have led to shorter lines of trucks, thus improving the overall traffic congestion at the Port of Miami as well.

What Should A Metal Recycling Company Ask When Purchasing a Truck Scale?

Posted on by

For the next few entries we are going to answer some frequently asked questions about buying a truck scale. In the first entry we answer the question below.

What exactly is the difference amongst a full-length truck scale and an axle scale? Which variety do you notice recyclers employing most frequently?

An axle scale is designed to weigh only a single individual axle of a large vehicle at one time and may possibly give an overall total gross weight at the conclusion of weighing the truck. Axle scales are frequently portable, but could also be permanent installations as well. For example, check out the video below.

On the other hand, full-length truck scales, usually 70 feet long can weigh the entire truck (all axles included) in a single weighment, so axle scales need more time to weigh up a truck than full-length weighing machines. Recyclers will normally use full-length 18 wheeler scales due to the fact axle scales will not be NTEP legal for trade, which is needed in the recycling industry.

Recycling businesses are having to pay men and women depending on the load of the timber in their particular vehicle load, so consequently it’s important for the scale to be NTEP listed for correct weighments. In brief, the process involves individuals bringing in their recycled copper, the metal recycling company compensates these individuals for it depending on the weight displayed on their truck scale, and so the recycler then usually utilizes a railcar to deliver the material to steel mills. For more information on Cardinal Truck Scales, contact authorized distributor Central Carolina Scale, located in Sanford NC.

What Type Of Scale Should A Metal Recycler Buy?

Posted on by

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.

What Is The General Guidelines For Ordering A Truck Scale?

Posted on by

This week’s question asks what sort of site preparation could be required prior to scale installment?

Site preparation will vary due to whether the set up is a new or replacement truck scale. A concrete deck truck scale will add construction time on account of pouring the concrete inside the scale deck and curing time.

For brand new installs, the common truck scale installation method is as follows. Blueprints arrive from the scale vendor. After that, scale house is built or installed on location. Next, concrete foundation and approach ramps poured by either scale service business or the consumer. And then, truck scale is delivered from the scale supplier. After that, scale service organization wires the truck scale to the scale house and links all the peripherals. At last, calibration and certification with test weights and weight cart.

Much less site prep work is needed and faster installation times can sometimes be achieved with systems like Cardinal SnapStream Wireless Truck Scales, which provide wireless radio frequency connection in between the truck scale and the weight indicator in the scale house. Moreover, all peripheral gear like remote displays, computers and printers could be attached wirelessly with SnapStream, which perhaps conserves a large number of bucks in installation costs. SnapStream is really a fully-integrated NTEP legal-for-trade wireless scale system for commercial recycling applications enabling connectivity up to 1 mile line of sight between the truck scale and scale house.

Cardinal SnapStream is a fully-integrated NTEP legal-for-trade wireless scale system for commercial applications. It’s completely proprietary to Cardinal Scale and offers a number of competitive advantages for new (or pre-existing scale installations).  SnapStream allows a scale to send weight data wirelessly to an indicator and the indicator in turn to send that data wirelessly to a host of peripheral equipment such as remote displays, printers, PCs and networks. SnapStream is a digitally-controlled weighing and diagnostic system designed utilizing 802.15.4 Zigbee protocol for reliable and accurate weight and data transmission. SnapStream may be used with Cardinal Scale 205, 210, and 225 weight indicators, where scale diagnostics can be viewed directly on the digital weight indicator.

How Often Does A Truck Scale Have To Be Calibrated?

Posted on by

Spring is a great time to perform some general maintenance on your truck scale. A popular question we hear from folks is how often does a truck scale have to be tested, adjusted, and/or calibrated? Also, what factors can influence how often scales should be calibrated?

The general consensus is normal routine scale calibration is often determined by state requirements and the scale owner’s quality assurance standards which sometimes might be something as simple as comparing truck weights with a nearby truck scale owner. Many states require the truck scale to be tested and adjusted at least once per year. Furthermore, several states call for calibration to be carried out by way of the State Weights and Measures Department or utilize certified scale service organizations to carry out routine calibration. Of course, state certified test weights are needed for appropriate calibration accuracy.

As for the question of how often do you need to calibrate your scale, it’s usually a good idea to do this at least two or three times a year. Number of truck weighments per day and also the age of the scale add to how frequently a truck scale needs to be adjusted. In most cases you should try to work with a scale company that sells and services truck scales. The company should also have a test truck with certified test weights and a portable weight cart which will allow the scale company to drive the cart around the scale and position the weights in certain places on the scale deck to find little errors that might not be found with just test weights.

Initially, service trips and calibration charges might seem expensive but in many cases the savings a company will enjoy far outweighs the service fees. If a scale is tested and is off just a couple of graduations, that could be over 40 pounds of material you’re losing for each truck that drives over the scale. That could be pretty expensive as well.

Legal for Trade Truck Scales

Posted on by

Why should you purchase a scale that is Legal-for-Trade when you don’t intend to use the weighing instrument  in a commercial weighing setting? Defining a commercial weighing application can sometimes be difficult. Scales can be moved around your facility and get utilized for things that perhaps you didn’t originally intend. Basically, an NTEP approved device is required any time money changes hands based on a scale’s reading. Freight scales, for example, must be NTEP approved. For these situations government requires that a scale must pass tests put forth by the National Type Evaluation Program (NTEP). These regulations are meant to protect the consumer. Click here to see the rest of the story.

The other legal for trade question we wanted to discuss is related to Classes. Often you will see NTEP Legal for Trade Class III. But, what exactly does Class III mean? Handbook 44, the book that spells out rules and regulations for the weighing industry, separates weighing devices into five accuracy classes. Depending on the number and value of scale divisions, equipment can be either class I, II, III, IIIL, or IIII, with Class I having the highest precision. All Legal-for-Trade scales fall under one of these five classes.

Table 7a of Handbook 44 breaks down the description of each class. Class III states: All commercial weighing not otherwise specified, grain test scales, retail precious metals and semi-precious gem weighing, animal scales, postal scales, vehicle on-board weighing systems with a capacity less than or equal to 30,000 lb, and scales used to determine laundry charges.
