In-Motion Wheel Weighers Make Wake in Truck Scale Technology

For freight forwarders, shippers, and companies associated with logistics and transport functions, establishing internal systems to comply with highway truck weight regulations is critical. Stats reveal that overloaded trucks enhance damages to infrastructure and really pose greater hazards such as traffic accidents among the issues of other roads. With truck scale technology evolving, new systems and methods of weighing trucks are available.

Wheel weighers have become very advanced, low-profile weighing tools for many
different applications, including mining, farming, logistics, and freight.

In-motion wheel weighers, a type of portable truck scales, are one of the most highly-sought weighing systems in logistics and distribution sectors (as well as various other industries.) Highly-enforced regulations have prompted a lot of companies to adopt accurate, durable and reliable weighing devices to remove guess work. Offering optimal accuracy, efficiency, and portability, in-motion wheel weighers are among the best options available, and some truck scale companies are offering this advanced system for rent.

New Cutting-Edge Technology & Design

In-motion wheel weighers are lightweight and also completely mobile systems which can be used almost anywhere for heavy-duty vehicles weighing. They are really low-profile systems which feature an easy weighing platform in which trucks drive on.

As a truck passes over the weighing system, the scale will record the real weight of the vehicle and axle weight. They usually come with highly sensitive load cells which are capable of recording the exact weight of a truck. The system can then send the data to a particular remote terminal or mobile application.

The Evolution of Truck Scale Technology

Trucks that carry various loads or products from one place to another often need to be weighed, either to determine the load weight (and valued) or the entire truck to ensure it's within designated weight limits.

This measurements is often derived using truck scales, which give an accurate value truck axle weight and/or weight of the load carried by the truck. Truck scales may not seem like a big deal but they are quite important for companies to increase their profits and streamline their plans. While some companies may only require to weigh 10 trucks per day, other business models may be required to weigh thousands of trucks in a day.

Advancements & Adaptation of Truck Scales

The truck scale systems of today need to be accurate along with being reliable for providing the most value and use to the business owners. Since truck scales are faced by harsh weather conditions and constant running over by heavy trucks they need to be very durable and also need to provide correct measure for weight under varying weather and environmental conditions.

While earlier trucks were weighed by keeping them on a ramp and then separately measuring them one by one, a number of advancements have made it very easy to measure the weight of trucks. Also, accurate machines give a precise amount of weight of the trucks. Some of the advancements which have propelled the truck scales to a new generation include some of the following features.

Weigh-in-Motion Truck Scales

Weigh-in-motion is a feature in new truck scales which are able to measure the weight of a truck while it passes over them. These scales do not require the truck to stop but only require it to be moving with regular speeds or sometimes with reduced speed in the old versions.

Weigh-in-motion scales measure the gross weight and the axle weight of the vehicle as it passes over them. Often integrated as portable axle weighing scales, these systems are used in a number of places such as designing of pavements and bridges, enforcing a size and weight limit on vehicles etc.

Dynamic Design & Impervious Construction

Design of truck scales has been improved so that they can measure sensitive data without being damaged or needing calibration. Truck scales are made using function dynamics and static design principles using various technologies.

Today's truck scales are also designed to bear a number of unexpected environmental variables or damages such as rain, lightning, sunlight, etc. The weighing scales have been improved and classified into various sizes depending on the size of trucks they would be used to measure.

Integrated Truck Scale Software

Software integration into the truck weight scales helps the users to record the data easily at all times. There are also an automatic feature in most of the truck scales which helps them to measure the weight of all the trucks which pass over them.

Software integration into the weighing scales makes them much easier to use without much expertise or hassle. The data can be clubbed easily and also computed using different procedures. The data can also be transferred with ease and sent to various authorities and people for inspection or review.

Overall, the truck scales have gone a massive revolution due to these features making them much better to use for various purposes.

Weigh-In-Motion Axle Scales: 3 Leading Systems Worth Every Penny

There are many different axle weighing solutions engineered to suit a plethora of vehicle weighing requirements. Some of these weighing solutions include single axle weighing through dual, tri, or even quad-axles. Each of these axle scale systems have been specially designed to capture and save weight data quickly and accurately.

Even more, there are several reasons why it's a good idea to ensure truck compliance to weight regulation. Weigh-in-motion technologies allow trucks and other transport vehicles to be weighed directly in the traffic flow, without any stoppages and disruption to operations. As overloaded trucks and transport vehicles pose serious threats to road transport operations, it can increase risks for road users and cause severe impacts on the durability of infrastructure and the vehicle itself.

Axle Scales: Vital Tools to Minimize Overloading

When it comes to monitoring road traffic loads, attention is now mainly focused not only on basic vehicle weight but also on axle and wheel load. That said, an overloaded truck is more likely to be involved in an accident and have more severe consequences than a properly loaded truck. The heavier the truck, the higher inertia, which may result in stronger forces and damage - to other vehicles or to the infrastructure.

Generally speaking, when the current load exceeds the maximum permitted limited of a vehicle, several consequences may occur.

In the first place, an overloaded truck is often less stable because of the increased height at the center of gravity and more inertia of the vehicle bodies. Additionally, the braking system of any vehicle is designed for the maximum allowable load indicated on the documents. Any weight in excess will reduce the braking capacity of your vehicle and may even damage the braking system.

An overloaded truck becomes underpowered, which results in lower speeds and longer overtaking, with a higher risk of tire blowouts. That said, overloads can even induce tire overheat. When flammable or hazardous goods are transported in a truck, overloads located in the truck increase both he risk and severity of a fire, due to accident and loss of control of a vehicle.

Weigh-in-Motion Axle Scale Systems

There are three primary types of weigh-in motion axle scale systems. These include, but are not limited to:

High-Speed Weigh-in-Motion Axle Scales

High speed weigh-in-motion axle scales are often used as a pre-selection system for low speed weighing stations. This in-motion truck scale system connects with the weight measurement sensors, loop detectors and control units located in a cabinet placed beside the road. This system enables weighing of the vehicles while they are enroute without hindering traffic system.

Low-Speed Weigh-in-Motion Axle Scales

Another weigh-in-motion axle scale system is a low speed system. This system is used in applications in which vehicle weights must be determined accurately such as road side control stations provided by legal authorities, vehicle inspection stations operated by public or private establishments. This system usually consists of weight indicator, computer and scale programs.

Portable Weigh-in-Motion Axle Scales

There is a third category of weigh-in-motion systems and it's a portable one. This category of portable truck axle scales provides accurate weights for large off-road vehicles. Compared to the first two solutions, the portable in-motion axle scale is actually ideal for weighing in off-road conditions - that said in bad weather and terrain conditions. The best example of a portable weighing system is AXW-Series Axle Scales. This system is built from a single piece of aluminium, providing lightweight portability and exceptional environmental protection.

3 Revolutionary Weighing Systems That Are Redefining Industry Standards

Technology is expanding in every industry, and high-volume weighing and measurement has not been left behind. There are three different types of technology focal to truck scales or industrial weighing systems that are helping to advance the overall efficiency and productivity of operators (i.e. mining companies, construction projects, farming applications, public works programs, etc.)

Over time, new developments are cutting out the bottlenecks that can arise in industry when trucks, equipment, products, etc. must be weighed both accurately and efficiently. In the past, this necessary step could result in a significant loss of both time and money. 

Recent advancements have caused many industrial trailblazers to reassess the way they do business; resulting in streamlined, efficient industrial, mining, and agricultural methods that improve safety and management. Below we profile three revolutionary weighing systems are redefining the industry standards.

On-Board Weighing Systems

The first technological advancement is defined as on-board weighing system. These scales are integrated directly on vehicles and equipment to provide seamless, highly efficient weighing methods. On-board weighing systems allow for an efficient use of time. Instead of bringing a product to a specified location for measurement, the truck is equipped with this technology can be taken to the products. Not only does this option save time, but it could prevent costly mistakes and verify accuracy onsite. 

For example, wheel loader scales allow one to use onboard weighing to optimize throughput and efficiency. Many loader scales work with multiple wheel loaders and are designed for simple operations. The operator interface has been programmed to give information in graphs for ease of interpretation of the data. While there are many different on-board weighing systems from various industry suppliers, many systems also provide multiple communication protocol options including mobile access. 

In-Motion Truck Scales

The next technological advancement is in the development of In-Motion Truck Scales. This method uses portable truck axle scales that enable users to drive over portable weighing pads at slow speeds. This method provides an 'in motion’ method that is easy to use and yet provides accurate weight measurement. 

Weigh in-motion scales have many practical applications, including roadside inspection stations. However, they can save time and money in many industrial applications as well.

This technology allows one to accurately weigh a vehicle quickly. By utilizing advanced sensors, these systems can measure the vertical force of a vehicle so that the accuracy is not altered by the rapidity of the measurement. 

Volumetric Load Scanning Technology

Finally, Volumetric Load Scanning Technology, while not an actual truck scale, has provided a revolutionary alternative by using laser scanning technology to scan truck beds or other contained spaces to generate 3D volume metrics that can be converted into weight metrics based on material density and other operator inputs.


This load volume scanner system can be executed rapidly and accurately. Because of the low cost of installation and maintenance costs, such as calibration and repairs, this method is gaining in popularity. The calculations are accurate for almost any application because the operator input allows one to customize the system readily for different scenarios.

The accessibility of the load scanner system, including mobile applications, makes it a good option for communicating and sharing information. Learn more about the industry's most advanced load scanner system by visiting WalzScale.com.

Industry Advancements With In-motion Weigh Scale Technology

In-motion weigh scales are devices that are designed to measure the full weight of a vehicle as it moves through the measuring site (or in most cases, passed over the scale.) This advanced kind of weigh scale system does not require vehicles to come to a complete stop. Most in-motion scales only require the vehicle to slowly pass over the unit to make accurate weight calculations.

This technology is very useful because it allows vehicles to keep moving, helping operations increase throughout in their weighing processes. As a result, in-motion weighing technology is being integrated on many different applications, spanning from portable truck scales (or weigh pads) to in-motion rail scales on train track.

The Technology Behind In-motion Weigh Scales

The technology that is applied to these devices is high-end technology. Its sensors, primarily made of quartz crystals and placed on ground level, sense only the normal force that acts on the sensors (i.e. the force perpendicular to the ground, vertical force). Thus, the speed and the friction are not measured, leaving space only for the vehicles weight.

The quarts apply some electric charge that is proportional to the vehicle’s weight force. Through the use of physics, scientists have managed to form a formula to calculate the weight using that technology. But weighing in motion (WIM) devices are not all made of the same technology. There are several kind of WIM units.

• Laser system WIM devices - They basically measure the displacement of the rail as the vehicle moves through it. Through some calculations they manage to calculate the weight.
• Load cell system WIM units - They calculate the weight of the vehicle by measuring the constriction of the strain in the load rather than the rails.
• Fiber optical measuring WIM devices - These systems measure the change of light ray illumination that is primarily produced by bending.

Applications of In-motion Weighing Scales

Below are a few of the most common applications of in-motion weighing scales:

1. This technology can also measure train’s weight. Otherwise known as in-motion rail scales, these simple systems are deployable within 30 minutes and requires no maintenance. The revolutionary and enhanced algorithms that are encompassed in the WIM’s software allow for a very accurate measurement. In-motion rail scale systems allows for a very quickly and accurate measurement of rail assets.



2. Additionally, this technology is very useful in highways. This technology allows the measurement of vehicle’s weight that pass through a certain place without stopping the traffic. The device will detect the vehicles that have broken the regulations and will automatically notify the officers in charge of the vehicle’s location. Then, the officer will take care of the problem.

3. Another use of this technology is in-motion on-board scales. There are thousands of loaded trucks that send and receive supplies daily. All of them must be measured, a process that takes time. But, thanks to the innovative WIM on board scale technology, it now takes much shorter time.

These devices are implemented within the truck, conveyor belt, or any other kind of equipment, and the sensors wirelessly inform the software about the weight of the products. This saves time and money as well. Most of these on-board scale products are cost efficient. Their price ranges from several hundred to a few thousand dollars.

4. Lastly, this technology is getting implemented in airports as well. While the plane moves through the sensors, they measure the weight and compare it to the pilot’s log in order to make sure that there is enough fuel to reach the destination. This saves lots of time.
