Above ground truck scales play a pivotal role in many different applications as they provide critical weight data for outgoing and incoming vehicles as well as bulk loading activities. Lately, cutting edge communication technology, user-friendly software, and versatile instrumentation is increasingly expanding the scope of above-ground truck scales.
As a result, these advancements are improving the data collection and operational capabilities of such weighing systems.
How Above Ground Truck Scales Operate
Many above ground truck scales are usually operated in a drive-through manner: the vehicles drive on from one end and off at the other end. But if there is little space, vehicles can drive on and off from one end. In applications where vehicles are weighed in and out, then there is no choice but to operate two different weighbridges. This streamlines traffic flow and makes it easier to service one bridge while the other is operational. However, in many applications, a single weighbridge is enough.
Above Ground Truck Scale Design
Mechanical above ground scales are now obsolete, giving way to fully electronic versions where strain guage load cells connected to weight instrumentation support the weighbridge deck section. Above ground truck scales feature probably the strongest and most efficient design as the side frames ensure that vehicles drive through the middle of the bridge. The approach and departure ramps may be constructed of steel.
Alternatively, they may be pre-cast in concrete on-site. The advantage of having removable steel ramps is that, in case there is a need for relocation, they may be moved with the bridge, thus, leaving the site level. Although they're less common with portable trucks scales/wheel weighers now dominating the market, portable above ground weighbirdge truck scales are still used for some applications
Finish of the Weighbridge
Because weighbridges often operate in harsh environments where they are exposed to the elements, it is important that they have a well-structured finishing procedure that will provide optimum longevity. During the coating process, the steel is shot-blasted so as to remove mild scale and surface imperfections before painting. This will ensure that surface coating applications adhere well to the steel.
Weighbridges also feature built-in restraints that can withstand the end to end forces that are generated whenever vehicles drive on and off the weighbridge- especially when there is heavy braking. The end to end forces can damage critical parts such as the load cells as well as causing serious damage to the surrounding structure.
Truck Scale Load Cells
These are the most critical components of weighbridges as they are the above ground truck scale’s measuring sensors. They feature modern sealing methods, and their construction provides the much-needed protection from the environment. They also feature a well-designed mounting hardware which ensures the load is introduced optimally.
Common Applications of the Above Ground Truck Scales
The above ground truck scales, especially portable truck scales and weighbridges from Walz Scale, are ubiquitous in industries that produce or move bulk items. For example, you will see them in quarries, agricultural production, recycling centers, household production goods, electrical equipment production, and many places.
The above ground scales are useful in many other custom environments. That is because accurate weight measurement is very necessary when products that are meant to be delivered are paid for according to the weight. When it comes to advanced truck scales, Walz Scale is one of the most trusted manufacturers of extremely accurate weighbridges for many industry applications. The above ground truck scale is arguably the company’s most popular scale.
Freight forwarders and 3PL companies operate in a very sensitive business environment. The small details can have a major impact on the profitability of the company and the satisfaction of customers. For this reason, nothing can be left to chance, especially in weighing loads being shipped for transport.
The ideal truck scale for freight forwarders should help to prevent overloading while also enabling safe and optimal loading of vehicles. Further, investing in an truck scale system allows freight forwarders and 3PL companies to offer timely and reliable services to customers while also maximizing their profitability.
Truck scales should also help to prevent a variance between the actual shipping weight and the stated weight. Among the top three truck scales that freight forwarders and 3PL companies include the weighbridge truck scales, portable axle scales, and on-board truck scales.
Weighbridge Truck Scales
The weighbridge truck scales are highly popular with high-volume freight forwarders and 3PL companies due to their ability to handle high-volume loads efficiently and effectively. Truck weighbridge scales can help optimize weighing operations to ensure faster throughput, which is an important aspect of freight forwarders profitability. They feature robust weight sensors, rugged designs, durable materials and high quality manufacturing, which ensures dependability and accuracy even in tough industrial environments.
Depending on the location and the use of the scale, they can be pit or surface mounted. Furthermore, they can be paired with a wide range of accessories, indicators and software for a complete customized weighing and data management solution. Weighbridges work by utilizing multiple load cells that are capped with flat load plates for accurate readings of the measurements along the weighing platform.
Portable Axle Scales
Portable axle scales are highly useful where portability is needed or in areas where construction of concrete foundations is not possible. They are suitable for freight forwarders and 3PL companies because they can efficiently handle loads of up to 80,000 lbs. Portable axle scales come in wide variety of lengths, configurations, and capacities to match varying needs of freight forwarders. These portable scales used to weigh trucks can also be customized to allow the use various multiple peripheral components from large weight terminals to digital weight terminals, and receipt and ticket printers.
Depending on the application, the portable axle scales can either be run in in-motion or dynamic weighing mode, which allows freight forwarders to weigh vehicles without the need to stop for increased throughput. Portable axle scales for trucks can also feature built-in or external battery to enable weighing in remote areas.
On-board Truck Scales
On-board truck scales offer freight forwarders with an efficient, cost-effective way to calculate and monitor the weight of trucks. The on-board scales work by monitoring the change in electrical resistance created by the strain caused by the payload.
When companies get on-board truck scales from Walz Scale, the on-board scale systems can be customized to match specific 3PL company's weighing needs and requirements, but the basic design wires the system through the display and the truck ignition switch. The wiring ensures instant application. The system becomes active once the vehicle is ignited and the driver cannot alter anything without the right authorization. The driver monitors the truck load through the display while alarm tones are put in place to warm when the truck surpasses the standard weight.
Almost every day in traffic reports, we hear the horror stories of over-turned trucks on the highway, wiping out several cars and passengers. And for most of us, we get nervous when we have to drive behind these cumbersome giants on the road.
Transporting heavy loads on the highway has many potential dangers, and that is why there are strict highway regulations pertaining to the weight a truck can carry. Should these regulations not be adhered to, the company managing the truck can face serious penalties and overloading fines.
For this reason, in most transportation and logistics management companies it is important that the load of the truck is weighed ensure the trucks are within legal weight limits. Aside from the obvious safety concerns, overloaded trucks can lead to other issues and complications for owners. Constant overloading of a truck can lead more wear and tear on the truck, and truck repairs are far from cheap.
For logistics management companies that deal in the transport business, it is important to have the proper weighing systems in place to ensure each truck is legal and safe from transport. There are several truck scales made specifically for this purpose, but two particular types of truck scale systems are most common for logistics management companies. These include: weighbridge truck scales and on-board truck scales.
Weighbridge Truck Scales
Weighbridge truck scales are a special metal bridge made that is installed at a truck departure venue (although there are specialized portable version available.) The loaded truck will drive up onto this bridge to be weighed.
An advantage of weighbridge truck scales is that they can be used on a multitude of trucks as well as other heavy duty material. It is definitely versatile for a wide range vehicles, when properly calibrated. A disadvantage is that weighbridge scales for trucks are often installed to fixed concrete foundations, and they don't offer the same level or convenience or efficiency as portable truck scales or on-board truck scales. Nonetheless, weighbridges provide a great option for companies in transport and logistics management.
On-board Truck Scales
On-board truck scales are wireless systems that are fitted to the truck. These on-board scale systems use a special signal which is transmitted to a monitor. How they work is by using load cell technology as well as pressure readings of the air suspension. This reading will determine the weight of the load that is being place on the vehicle axis.
On-board scales can be installed on a wide variety of trucks, and they are specially fitted to meet the trucks requirements. The primary advantage is that the scale and readout is on the truck itself, eliminating the need to drive-up to an external scale unit. The disadvantage is that each truck in the transport fleet will need have to have its own scale fitted and installed. This can be both costly and time consuming, depending on the size of the company.

Weighing scales are very important type of equipment needed at various levels of operation that involves logistics. In essence, the shipping and logistics industry thrives on accurate measurements to avoid penalties and prevent accidents.
Weighbridge truck scales are used to facilitate accurate measurement of loads being shipped. A typical weighbridge scale depicts various features that aid quick capturing and recording of truck weights, particularly the loads contained in them. Since the shipping and logistics sector is very broad and operates in large-scale margins, weighbridge scales are often fixed permanently on the weighing platform.
Weighbridge scales are often generally referred to as "truck scales," although there are vast difference in the types of truck scales available (i.e. portable truck scales, onboard truck weigh scales, etc.) Weighbridges are unique in that they are often fixed in a certain location where they will used consistently for several years.
Streamlining Logistics with Weighbridge Scales
Weighbridge truck scales are used in various industries and sectors of the economy including agriculture, mining, shipping and logistics. These scales have been used for years to optimize the measurement process. However, modern scales incorporate computer technologies and efficiencies.
They are therefore characterized by various enhancement features that not only guarantee accuracy, but also bring in important metrics among other varied benefits. A quintessential weighbridge scale used in streamlining logistics consists of three main sets of features; sensors, processor and output displays.
- Sensors - These features are installed on the truck road/rail where the load passes through. They are capable of quickly capturing readings of trucks and truck loads. Modern sensors use high-end computer technologies that allow minimal contact while giving the most accurate reading.
- Processor - This feature basically uses the information read by sensors to calculate accurate weights of truck loads at all levels. Sensors usually capture several readings at different positions. The processor uses all these inputs to give the ultimate weight.
- Output displays - unlike traditional scales, today’s output displays characterize large ergonomic screens that allow quick reading of weights. These displays are separate parts and allow reading to be taken from a distance.
The logistics and shipping industry is tasked with measuring numerous loads that pass through ports and pre-shipment warehouses on a daily basis. Their activities require quick measurement of each load and more importantly precision in accuracy. If these attributes are not there, companies operating this business can suffer violation penalties of overloading and even loose payload revenues.
It is therefore an obligation to ensure accuracy in measurement. Weighbridge scales bring the efficiencies of computer technologies by significantly reducing the time needed to measure trucks and truck loads. They feature memories capable of holding recorded data that is used in tracking and making various decisions. With these scales, optimizing logistics one load at a time becomes much easier and quicker. Their efficiency ensures that there is no delays in measurement and shipments are made in due time.
While weighbridge truck scales bring various benefits to the business, there are so many of them and choosing the right one may be daunting. Ensure the chosen scale can be perfectly installed on your truck rails, gives accurate readings and suites your specific needs.
Weighbridge truck scales are inseparable parts of any large-scale venture that involves measurement of loads. They are very useful for logistics, agriculture and mining ventures. However, ensure you choose the best options that will bring forth above mentioned efficiencies to your business.
