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.
