Answering Your Questions About Truck Scale Load Cells & Mounting Systems

Posted on by

The majority of this article is provided by Rice Lake Weighing Systems. We have also added a few insights and thoughts of our own as well.

What is a Load Cell?

A load cell, also commonly referred to as a transducer, converts a mechanical force into an electrical signal. Basically, the load cell bends slightly when weight is applied.

In a compression mounted load cell where the load cell is beneath the weighing vessel, like a truck scale, the load cell compresses when a load is applied. This would apply to scales like the Cardinal PRC which has the SCA load cells.

The load cell produces an analog output signal that is proportional to the applied weight or force. The load cell transmits this signal to a digital weight indicator that converts the signal into a digital weight measurement.

When an application requires multiple load cells, each load cell should measure the same proportion of the total load. So in a four load cell system, each load cell should measure exactly one quarter of the load.

Many load cells are proprietary to a specific manufacturer, and may require additional maintenance and costs of ownership. Carefully discuss with your scale supplier all options for load cell systems.

Analog Load Cells
The most common load cells on the market work on the strain gauge principle. All load cells need to convert their analog values to digital before the load’s weight reading can be displayed on an indicator.

Some load cells are directly cabled to the digital weight indicator where the translation occurs. Other cells are connected to summing junction boxes on the scale where the box sums analog readings from multiple load cells, converts it to a digital signal and sends that signal to the digital weight indicator.

Hydraulic Load Cells (pressure transmitters)
Unlike most other load cells, hydraulic load cells do not use strain gauges or internal circuitry. Instead, hydraulic load cells contain hydraulic fluid, and during compression, a change in pressure is created and transmitted via tubing to a summing system where the pressure is applied to an analog load cell to determine weight.

The advantages of the hydraulic load cell typically relate to being resistant to lightning damage. The disadvantage of this type of scale and replacement load cell is the cost.

Analog-to-Digital Load Cells
Some analog load cells perform the analog-to-digital signal conversion within the load cell housing. Although sometimes referred to as digital load cells, the cell still measures in analog. Making the conversion from an analog signal to a digital signal in the load cell allows the system to compare the output of individual load cells and perform a diagnostic analysis based on that information.

Some would say that because the conversion happens in the load cell, sensitive electronic components are increased throughout the scale system, making them susceptible to damage from vibration, moisture and increased solder joints.

Types of Load Cells Found in Truck Scales

Double Ended Shear Beam
This is the most widely used vehicle scale load cell configuration in North America. A double-ended shear beam load cell is a compression load cell that offers a large capacity range from 1,000 to 200,000 pounds.

The double-ended shear beam is secured at both ends with the load applied to the center of the load cell. As in all shear beam designs, the strain gauges are mounted on a thin web in the center of the cell’s machined cavity.

The load cell also has the advantages of being less expensive in high capacity applications than the canister load cell because it does not require checking, making it virtually a maintenance free solution.

Canister
A canister load cell is the oldest load cell type. Also a compression device, it is shaped like a vertical canister and can handle loads from 100 to 1,000,000 pounds.

It is either hermetically sealed or welded to protect the gauges. This load cell’s drawbacks include the fact that it requires checking — installing check or stay rods to hold the weighing vessel in place on the load cell’s top plate during weighing.

For these reasons, many canister load cells on the market today are used to replace older canister load cells on existing weighing systems.

Rocker Column
Some manufacturers prefer rocker column load cells because they are inexpensive. However, they require check rods and bumper bolts that require maintenance, increasing your cost of ownership. The cost saved by the manufacturer on the raw material is passed down the line to the end user in the form of additional maintenance.

Load Cells Are Usually Manufactured as either Alloy Steel or Stainless Steel 

Truck scale load cells are generally made of stainless steel or alloy steel, but most manufacturers offer a variety of load cell solutions that best fit your application needs.

Alloy Steel Load Cells
Load cells manufactured from tool alloy steel elements are by far the most popular cells in use today. The cost to performance ratio is better compared to either aluminum or stainless steel designs. The most popular alloys are 4330 and 4340 because they have low creep (the change in load cell output over time while under load) and low hysteresis (the difference between load cell output readings for the same applied load).

Stainless Steel Load Cells
Stainless steel cells are more expensive than tool alloy steel load cells. They are sometimes fitted with hermetically sealed web cavities, which make them an ideal choice for corrosive, high-moisture applications. Stainless steel load cells that are not hermetically sealed have little advantage over comparable cells constructed of tool alloy steel, other than a higher resistance to corrosion.

We hope you enjoyed learning more about the different load cells found in the average truck scale.

Maintenance and Cleaning Requirements for a Truck Scale Weighbridge

Posted on by

Keeping your Truck Scale well maintained and clean is an important part of truck scale ownership. Not only is it good practice to keep your weighbridge clean, it also contributes to a pro active scale maintenance plan and can significantly reduce the risk of equipment downtime and inaccurate weighing.

Before we get very far with this entry, lets clarify one thing… When we say to clean your truck scale, we are typically referring to the areas where mud and dirt can build up and cause weighing errors. Having a pristine scale diamond tread platform is great but that is not what we are referring to when we ask, is your scale clean?

You can see in the picture below an example. The photo on the left shows the scale before cleaning. Notice all the dirt on top of the concrete, especially between the approach ramp and the scale? Now look at the photo on the right after cleaning. You can see the concrete and very little dirt is left at all.

truck scale dirt buildup causing errors

Over time, the build-up of mud and debris can have a negative impact on a weighbridge performance. Compacted mud can set hard and reduce the movement of the weighbridge. This in turn causes reduced accuracy in weighing. Certain types of site environment will suffer more with mud and related issues and weather conditions can also play a part.

Keep in mind, weighbridge cleaning can be a balancing act. You need to remove the mud and buildup so the scale platform can perform correctly. However, the water jet force required to remove dirt and debris from around a weighbridge’s critical weighing points can, if not performed correctly, damage load cells, cables, junction boxes, and summing boards.

When cleaning the scale, the lightest amount of water pressure you can use and still get adequate cleaning, the better.

Weighbridge maintenance should take place as part of a daily or weekly routine depending on the type of site. The build-up of debris and water should be monitored and obstructions should be removed from beneath the scale to provide clearance between the weighbridge and the ground. Otherwise, your scale accuracy will suffer.

Pit weighbridges should be checked to make sure clearances are clean and the correct gap between the deck and pit wall are in place. ‘T’ section rubber can be used to help maintain gaps and should be replaced if worn or damaged. Regular end-middle-end tests with a loaded truck should be carried out to review the accuracy of the scale to see if there are any buildup issues. This basic cleaning and maintenance can be carried out by a site foreman or truck scale weighbridge operator.

If you are a current customer and you are curious about cleaning your truck scale, contact us and we can discuss this further or we can show you the key areas during our next scheduled maintenance visit. If you’re interested in our services, please contact us at (919) 776-7737.

Benefits of Cardinal Digital Truck Scales

Posted on by

Cardinal Armor series Smartcell digital truck scales have several distinct benefits to you, the customer. First there is the heavy duty weighbridge design the Cardinal Armor digital truck scale uses. For example, the steel deck has (12) 12 inch eye beams across the scale but most important is there’s no moving parts under the scale.

ADVANTAGES OF A DIGITAL TRUCK SCALE

With a traditional truck scale, when it comes to debris build-up under the scale, that you typically see in landfills, quarries, sand and gravel businesses; all of that debris can cause problems under the scale and cause binding. Then you will be forced to have folks out there power washing the truck scale, trying to get the scale to work properly because safe linkage systems or load cells that are mounted to piers; the debris impedes on that critical weighing process.

This can often lead to down time for cleaning and can also lead to your scale being rejected when being tested by the State weights and measures inspector.

Another key element of the Cardinal Armor digital truck scale is simple connections which can also lead to limited downtime. Most important there is no power running to the scale other than the home run cable, that’s very important. Do you know what lightning, rain, and snow can do over time to the junction boxes of a traditional truck scale? There’s over a hundred and eight connection points in many standard analog truck scales.

digital truck scales

But, with the armor digital system, there’s ten. There’s five wires that plug into the terminal connector to go to the first load cell and there’s five that you simply wire into the weight indicator in fact Cardinal chooses 225 and the 825 as indicators of choice but most important for you; you want limited downtime for the life of the truck scale.

How Can I Send Weight Data From My Scale To My Computer?

Posted on by

At Central Carolina Scale we focus on scales and weighing equipment, first and foremost. That’s what we’ve always done. We are constantly working and training to be the best and most knowledgeable scale company that we can be. Now most of that training and on the job training focuses on digital weighing indicators, load cells, scales,  etc… We send scale weight information to various devices such as remote displays.

Customers have always been curious on how to send weight data from the scale to the computer since personal computers and laptops became prevalent.

send scale weight to computer

When it comes to sending your scale weight data from the actual digital weighing scale to the computer, how do you accomplish this task?

It actually might be easier than you might think and something that you can accomplish on your own using our scale equipment and a readily available accessory.

Please note, if you are operating a legal for trade weighing scenario, then you will need to make sure that any software or method that you utilize is legal to use. For example, if you are operating a truck scale and you are looking to send truck weights to your computer, then you will most likely need to utilize a software like Cardinal WinVRS or Rice Lake onTrak. If you are using a Doran Scales indicator, you would be interested to know they have made great software available for their products. The Doran Excelerator is likely the most basic software that is offered by Doran; it allows weight data to be taken from the scale readout and placed into Microsoft Excel. Doran also has more advanced software packages available.

USB Scale

Cardinal Scale Manufacturing also offers a USB option for many of their weight indicators, which makes sending weight data from the scale controller to a USB thumb drive very simple. You can just take the USB stick out of the indicator, load it into your PC and see the weight data on your computer screen.

If you’re using a digital counting scale like the Counterpart, Rice Lake has the WeighVault computer software, which is a comprehensive software package that stores and manages data on your PC. With Counterpart, you can create custom reports for inventory, threshold, location and more. It is designed for operators with minimal computer experience and managers who require quick and accurate information. Scales can be added or moved on-the-fly without interrupting other scales operating on the network.

Likewise, the WeighVault is also available for the CW90 checkweigher. In this case, WeighVault allows CW-90/90X users to add, edit, and access IDs over a network connection. WeighVault surpasses the CW-90/90X’s 50 ID limitation and eliminates front-panel entry of ID parameters. It also collects data as transactions occur, and provides detailed transaction and productivity reports which can be exported to Excel, Word, or as a PDF.

In addition to scales with a digital USB output, there are also a few other choices available for end users to consider. 

TalTech WinWedge

TalTech WinWedge Serial Device Data Collection for serial devices, including meters, balances, scales or any RS232 instrument. WinWedge captures data directly to Excel, Access or any Windows application or web page. It can even send commands out a COM port so you can control your device through hotkeys, buttons, or DDE.

MicroRidge designs and manufactures a broad range of wired and wireless measurement collection solutions, including WedgeLink hardware and software keyboard wedges. Measurement collection is what they specialize in. They don’t manufacture gauges, but they support gauges from a wide variety of manufacturers. The products are made in the USA and support the broadest range of digital and RS-232 gauges, digital indicators, scales, and more. They also provide free unlimited and knowledgeable technical support on all of the products that they manufacture, particularly the keyboard wedge and software keyboard wedge.

Keyboard Wedge vs Hardware Wedge

A hardware wedge reads data from digital gauges or RS-232 devices and sends the data to the PC via a keyboard or USB port. The data sent by the hardware wedge looks like keyboard data to the current application. The more common applications that are used with keyboard wedges include Microsoft Excel, Microsoft Access, and other database types of applications.

A keyboard wedge is used when you are trying to get data from some type of measuring device into applications that cannot accept data from a serial port. A software keyboard wedge reads data from a serial port and passes this data to a PC application in such a manner that the application thinks the data is entered via the keyboard. 

Software and hardware keyboard wedges are used extensively in data acquisition applications that include statistical programs, spreadsheets, barcode, LIMS, etc. MicroRidge keyboard wedges can accept input data from any RS-232 serial device. The data is then passed to a Windows application in such a manner that the application thinks the data is actually coming from the keyboard.

Popular Question: How does the digital weight indicator prevent input of fluctuating weights?

The digital weight indicator can usually have a built-in solution to prevent the input of fluctuating weights. One of the key features is the Print-at-Stability function. This function ensures that the software only records weight readings when the object being weighed reaches a stable weight.

Popular Question: Can the digital weight indicator record weights automatically or manually?

The digital weight indicator or shipping scale provides users with the flexibility to choose how they want their data to be received. You could have your scale continuously sending weight data automatically or manually by pressing a button such as the Print key.

Does a scale with digital output mean the same thing as sending weight data to a computer?

Some scale users search for the term scale with digital output when they are searching for a scale that sends weight data to their computer although it is technically not quite the right terminology if you are looking to connect a scale to a computer.

Do you offer usb scale software  or rs232 weight scale software?

As mentioned in this entry, Winwedge is a good choice for many of you. Also Cardinal offers the PC Companion software which works with some of the Cardinal weight indicators. Doran offers Excelerator for weight data capture. AdamDu is also available for the data stream coming from an Adam scale indicator or weighing scales.

Inspecting and Testing Heavy Duty Truck Scales

Posted on by

At Central Carolina Scale in addition to selling and installing truck scales; we also check, test, adjust, and calibrate truck scales just about every working day of the year. We have factory trained technicians who can troubleshoot even the smallest problem areas like a load cell that might be creeping. We also have certified test weights and a weight cart which allows us to provide the highest level of truck scale service available in North Carolina. When we’re finished doing our scale check, we supply the customer with documentation that shows before and after readings and how much weight we tested the scale with, etc…

However, in quite a few cases, where money changes hands based on scale weight, the state of North Carolina will also check the customer’s truck scale to make sure it is weighing correctly and performing within legal for trade tolerances. The blog post linked below is a field trip that describes a state test in more detail.

The Standards Division checks any scales where “money changes hands.” This would include scales at grocery stores, livestock scales, buffets, agricultural-supply centers, highway patrol weigh stations and scrap metal facilities. Scales are checked on an annual basis or by complaint. The only exception is stockyards, which are checked twice a year.

When consumers bring unwanted appliances, metal debris or even old vehicles to a scrap metal facility the items are generally weighed on a truck scale. At some facilities, this scale can record up to 100,000 pounds of weight. The entire weight of the vehicle, trailer and scrap metal is recorded on the scale. After unloading inside the facility, the consumer then drives the emptied vehicle and trailer back over a scale at the exit and this weight is recorded. The consumer is paid for the difference of the two weights. Depending on the amount of scrap brought in, the amount could be a couple of hundred dollars.
weight cart testing scales

To check a heavy truck scale, Inspector Glenn Farmer uses a six-wheeled, gas-powered, steel test cart. A hydraulic arm is used to fill the cart with certified 1,000-pound and 500-pound weights. For the test, he uses a known weight (the cart plus added weight) and test different quadrants of the scale. A five-section scale would have 18 different test points. There are two different types of truck scales, mechanical and load. To test a mechanical scale, Farmer must move his cart side to side to record weight. To check the accuracy of a load scale, he moves the cart down the center of the scale.

The Standards Division uses National Institute of Standards and Technology guidelines to determine tolerance levels on the scales. A tolerance level is the amount of weight a scale is allowed to vary. For a scale that can measure more than 25,000 pounds of weight, the tolerance level would be 60 pounds. A scale that does not pass inspection must be pulled out of service until the facility fixes the problem. “Many times the issue is debris buildup in the crevices of the scale,” Farmer said. “Pine straw, cans and other debris can cause the scale not to weigh correctly.

Our advice to the company is to power wash or use an air hose to clean the area around the scale.” If the scale is still recording incorrect weights after cleaning, the facility may call a scale calibration company to fix the problem. Some facilities will have a representative from their scale company go along with the standards inspector on the day of their inspection. This means that most problems can be fixed immediately, and the facility doesn’t have to endure a prolonged shutdown of a scale if problems are found.

This was a nice write up about testing scales and how important it is to keep your scales weighing accurately. It’s always a good idea to keep your scales clean and weighing as accurate as possible, year round. One easy way to do that is to contact us at (919) 776-7737 and set up a maintenance schedule for your scales. You’ll save money and you will have accurate scales with the regular scale checks.

I Need Truck Scale Prices & How Much Does a Truck Scale Cost?

Posted on by

“I need a price on a truck scale”

or

“How much does a 70′ x 11′ foot truck scale cost?”

We typically get some version of these statements or questions just about every day.

A rough estimate, on average, would be $65K-$85K for a 70×11 truck scale. It could be a little less money and it certainly could be more money, depending on what you are looking to do. We’ve modified this number to try and account for the 2022 and 2023 inflationary price increases. This price estimate is for the scale. You also have other costs such as the foundation, delivery, installation, and more. See below and we’ll provide more details on those costs.

Bottomline, you need to work with a scale company and obtain a real quote to make sure of the current prices.

So if the Truck Scale Costs This Much, What Else is there to Consider?

We have written this article to help you in budgeting for a truck scale cost. While costs may vary from market to market, this provides an accurate range estimate while also highlighting other factors to consider with your specific installation. Everything that we have laid out below assumes a standard 70 ft. truck scale length.

Scale Foundation Excavation and Concrete Work (Estimate: $25,000 to $40,000)

The concrete work for the truck scale foundation is a very important step and should be handled by experienced workers. A typical foundation is made up of concrete piers poured below the local frost line and flush with the surrounding grade. A 4” washout slab is poured between the piers and helps to prevent vegetation growth while also allowing for material to be cleared from under the scale. A 10 foot flat and level approach is also required at each end of the scale. These aid in a smoother transition on and off the scale.

Lastly, sloped ramps will be required at each end of the approach. The typical ramp length will be around 25 feet for a 70′ scale. Some state Weights & Measures departments will have rules governing scale placement, under scale clearance and ramp lengths. Be sure to check with your local jurisdiction before breaking ground.

70’ x 11’ Scale Options: Sight Rail, Weight Indicator, Ticket Printer and 4” Remote Display. (Estimate: $12,000 to $25,000)

The 70’ x 11’ truck scale is the most common size for typical, over-the-road tractor-trailer weighing. A scale with all-steel construction allows for the scale to be delivered, installed, and weighing vehicles all on the same day. We provided the estimate for it up above in the first paragraph.

Safety sight rail is a very common option as the scale platform will typically be between 14” to 20” above the ground. This won’t help keep the truck on the scale but it will help guide the driver.

The basic weight indicator will display weight, process a truck in/out operation and print a ticket with transaction information.

Lastly, the 4” LED remote display is required in some states and is needed so truck operators can see that the scale reads ZERO prior to driving on the scale. The scoreboard also allows drivers to compare the printed weight with what is shown on the readout.

Flatbed Scale Freight, Crane for lifting and Installation / Calibration by Scale Service Company. (Estimate: $10,000 to $15,000)

Wide load flatbed freight is required for the scale to be shipped from the manufacturing facility to the installation site. Obviously, the further the flatbed truck must travel the more expensive the freight cost will be.

A crane will be required to off-load the flatbed and set the truck scale modules. Crane cost consists of time on-site and the size of crane required. A crane that can be positioned a few feet from the scale foundation will cost less than one that must be sized for extended reach due to obstructions such as buildings, power lines, and/or hoppers/silos.

A professional scale service company is typically involved with removing the scale from the flatbed, setting the scale on the foundation, anchoring the scale to the foundation, wiring the scale parts/accessories and calibrating the scale with certified weights.

TOTAL PROJECT COST FOR 70×11 TRUCK SCALE = $90,000 – $130,000
===========================================================

While we hope to have shared some insight in budgeting for your new truck scale, we need to mention that there are other situations that may arise to add significant costs to your truck scale project.

Some of these include but are not limited to:

Any project that happens after normal business hours or on weekends, or holidays.
Foundation additions such as concrete curbing, walkways and/or extended ramps to adjust for slope grade.
Excavation that encounters any type of utility service that will need to be relocated.
Excavation that encounters poor ground soil conditions or significant movement of soil because of elevations.
Electrical power, network wiring and/or communication wiring that needs to be trenched.

We understand that installing your first truck scale can be overwhelming and we are here to help. If you need an unbiased opinion or somebody to come out and look at your site, be sure to give us a call.

It’s hard to give an exact answer because every situation is a little different.

Maybe you’re replacing an existing CMI truck scale. Or perhaps you’re looking to extend a 60′ Weigh-Tronix truck scale into a 70′ scale. Or perhaps you’re putting in a brand new B-Tek scale and will need the concrete foundation formed and poured as well.

All of these scenarios work to show why it’s important to discuss your application with your scale salesperson to determine which products and services will work best for your situation.

Parts to Consider When Buying a Truck Scale

There are several major components involved with a truck scale purchase. First, is the actual scale itself, also sometimes called the Weighbridge, which is the main surface for the trucks being weighed. Weighbridge lengths vary from around 20 feet to over 100 feet. Widths vary from around 10 feet to 14 feet but are usually 11 feet. Typical weighbridge platform tops are either steel or concrete.

CLC Ratings

When you talk about the Weighbridge, you will also probably be told about CLC ratings. 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 of 8 feet apart. This is an area where you can save money in certain situations.

If you will have limited amounts of daily traffic, then chances are you may not need a really high CLC rated Weighbridge. Be sure to discuss this with your scale salesperson. 

Digital Weight Indicators

The Digital Weight Indicator is the next major component to consider, which displays your truck weight. We have several different truck scale indicator models to choose from. This is an important part of a truck scale. You’ll definitely want to choose a readout that has truck storage and serial ports for your ticket printer and remote display.

Load Cells

Loads cells are another important component to consider. Most truck scales usually have around eight cells inside. The three most common types of load cells are analog, digital, or hydraulic. Each has its own advantages. This is a subject you will definitely want to discuss with your scale salesperson as this can raise or lower the upfront cost, but will likely have a big impact on the long term cost of ownership.

Foundation

The next important part of a truck scale is the Foundation, which is simply the concrete base that the load cells and weighbridge rest on. These are normally above ground with approaches on each side. However, we also offer truck scales that sit in a pit.

Peripherals

Peripherals are the final components to consider when buying a truck scale. These include  items like truck management software, ticket printers, remote displays, traffic lights, intercoms, and other accessories. Some peripherals will be necessary while others are just nice to have, depending on your particular situation. 

If you contact more than one scale company, you may hear a distributor undermine a particular brand. For example; Rice Lake vs Cardinal Scale Manufacturing or Mettler Toledo vs Avery Weigh-Tronix. All of the companies mentioned are reputable brands, you will just need to determine which manufacturer you prefer, which local scale company you like best, and which features you want and need.

I Want To Buy A Scale That Is Made In The United States of America.

Posted on by

The title of this blog post sounds simple enough, right? Many customers are interested in purchasing lots of different items that are made in America versus buying items made in China and other countries. But, I would like to ask you a question…

What exactly do you consider “Made in America”?

The reason I bring this up is that it’s really difficult to find certain types of scales that meet a certain definition.

According to the FTC, for most products there is no law requiring manufacturers and marketers to make a “Made in USA” claim. But if a business chooses to make the claim, the FTC’s Made in USA standard applies. Made in USA means that “all or virtually all” the product has been made in America. That is, all significant parts, processing, and labor that go into the product must be of U.S. origin. Products should not contain any – or should contain only negligible – foreign content. The FTC’s Enforcement Policy Statement and its business guide, Complying with the Made in USA Standard, spell out the details, with examples of situations when domestic origin claims would be accurate and when they would be inappropriate.

For simplicity, let’s look at an industrial floor scale as an example.

Ok so you’re looking to buy an American Made floor scale. Did you know that almost every floor scale that is built in the USA utilizes (4) load cells that were made in China? With that being the case, let’s say your floor scale was built in Rice Lake, Wisconsin but uses load cells from China.  Do you still consider this scale an American Made item?

industrial floor scale

Did you also know that many of the junction boxes and summing boards are made overseas? Finally, did you know that the home run cable, the fifteen foot long cable that connects the scale to your digital weight indicator is probably constructed overseas? And, what about the steel used in the floor scale? Was it purchased domestically?

Sticking with the floor scale example, next area to consider is the digital weight indicator. Is it one hundred percent made in the USA? Were all the boards and components made in America? How about the display board? The plastic or stainless steel enclosure? Was the AC adapter made in the USA?

These are some interesting things to consider. I know of many people who can justify buying a scale that was constructed and calibrated in the USA but does utilize some Chinese components. However, there are some who absolutely want their products to be 100 % made in America.  Are there any scales that can one hundred percent meet that?

From our standpoint as a distributor it can be quite tricky since we are not involved in the actual manufacturing process. We have had numerous scale manufacturers tell us over the years that they build Made in the USA weighing equipment and then over time they slowly start substituting Chinese parts or in some cases, send all the manufacturing over to China. Unless the scale manufacturer tells us, sometimes we are not even aware that anything has changed in the manufacturing process.

So if buying a Made in the USA scale is important to you, contact us and we can help you. Just be sure to specify to us up front how flexible you wish to be when it comes to things like Chinese components such as load cells being a part of the final product.

In our experiences, many customers may originally start a transaction as a “Made in the USA” fanatic but once they discover certain prices and lead times for domestic components, they become a fanatic of “Made in U.S. from Imported Parts” or “Assembled in U.S.A.”.

DOES THE TRUCK SCALE PROVIDE ULTRA LOAD CELL PROTECTION?
SURVIVOR truck scales are designed with the load cell pocket integrated into the steel structure of the scale. Rice Lake truck scales are some of the most reliable truck scales in the market today. The design of their Survivor truck scale is important and is a big part of why they enjoy one of the lowest load cell failure rates in the industry.

DOES THE SCALE OFFER BREATHING ROOM BELOW THE PLATFORM?
SURVIVOR steel deck truck scales feature an open-bottom design, providing unrestricted airflow to eliminate rust-causing moisture buildup. Important feature since the scale is going to be providing you weights for many years of service.

IS THE SCALE TOUGH, FROM START TO FINISH?
High-performance epoxy primer and specialized hard-coat alkyd enamel is applied to all visible steel surfaces for a car-like finish that protects the scale from the elements. Once again, this is important since your truck scale is going to be out in the elements for many years.

IS THE SCALE AVAILABLE IN CUSTOM SIZES?
SURVIVOR truck scales can be custom-built to fit almost any project specification and application requirement including installations on existing foundations or in unique locations with space limitations. One important thing to consider is the width of your truck scale. Many customers will choose a 10 foot wide scale bridge.

Save Thousands of Dollars By Just Having Your Truck Scale Calibrated Regularly

Posted on by

Over time, truck scale accuracy can change due to a variety of issues, mostly usage and wear and tear. When you’re looking at a truck scale, accuracy is very important to your business because the value of the product you are transporting affects your bottom line and correlates to the weight you see displayed on the scale indicator. It can also be a safety concern as well, since truck weights must be in compliance with federal safety regulations.

You might think that a small issue doesn’t mean too much but the truth is that just small inaccuracies on a truck scale that is used regularly can accumulate to large costs for your company over time.

See the example below.

WEIGHMENTS PER DAY: 100
SCALE ERROR: 10 LB
PRICE PER POUND OF YOUR PRODUCT: $0.50
DAILY LOSS: $500
YEARLY LOSS: $150,000

As you can see from the example above, small errors can add up very quickly.

So, you might be thinking, but my scale was calibrated when it was installed, I should be good, right?

Well, the initial installation, does not guarantee continued accuracy. When a truck scale is first installed, it is tested by the scale company and the state weights and measures, both using certified test weights. This is done to ensure the scale’s accuracy as well protect the scale buyer, seller, and the scale installation company. At this point, the scale is certified and ready for everyday use.

However, the scale will need to be checked and adjusted at least a couple of times a year at a minimum. As you can see from the example above, just a few pounds of errors can cost your company a lot of money.

It’s important to remember, scale calibration does not lock in forever. It is dependent on several factors such as frequency of use, weather, gravity, electrical currents etc…. can throw off the accuracy of a measurement device.

The main point of this article is this. A truck scale should be periodically tested and adjusted if necessary. A commercial scale company, like Central Carolina Scale can check your truck scale on a regular basis or if you currently have a scale that has been “tagged out” by the state of North Carolina, CCS can check, test, and adjust your scale and get it back to weighing accurately.
