A weighbridge truck scale is a set of scales that are typically mounted on a concrete base and are used to weight entire road vehicles (or rail cars) and the objects that they are carrying. The load is measured by weighing the vehicle when it is first empty and then loaded, and taking the difference.
Weighbridge truck scales accomplish two tasks specifically: first, they allow truck owners to sell or charge by weight over the bridge and they effectively help prevent heavy fines or axle overloading by checking on the weight of both axles and taking the gross vehicle weight.
Second, they are used heavily by industries that move heavy items or manufacture them, like the mining industry, the garbage and recycling industry, and are used to haul electrical equipment. Because its possible to know the weight of the vehicle, they make keeping track of the flow of equipment and items in and out of differing places easier.
How do Weighbridge Truck Scales Work?
Truck scales are usually built from steel or concrete. They are either mounted at the surface with an accompanying ramp to lead up a short distance, with the weighing equipment below, or they are pit mounted with the weighing device in a pit – this ensures that the surface where objects are weighed on is flush with the road.
The weight of the load on a weighbridge truck scale is measured by load-cells, transducers that can be found in any weighing system. They work by converting a small change in resistance into an electrical signal that is utilized. After conversion, the signal undergoes filtration. It is calibrated, and then the indicator displays it digitally. However, some weighbridge truck scale suppliers offer differing solutions that utilize different types of technology. For instance, weighbridge truck scales supplier, offers a complete array of weighbridge scales for sale.
Weighbridge Scales' Load Sensor Technology
Weighbridge truck scales need to take the momentum that is created when a truck moves, or applies its brakes. As kinetic energy transfers from the deck of the weighbridge structure to the ground, the weighbridge needs to avoid transmitting this energy through the load cells (components within the weighbridge scale load sensor.
There should be a restraining mechanism in place that can move these forces away from the mountings and the load-cells. Truck owners need to be sure that their restraint systems are not faulty or inadequate in any way because this can result in the weighbridge deck moving excessively. When this happens, the forces are magnified to a destructive level that can undermine the integrity of the weighbridge truck scale, and logically, the accuracy of its readings.
One way to do this is by using a restrain post system. This is mounted in the middle of the weighbridge truck scale because it needs to compensate for temperature changes in the environment that could dramatically change the length of the weighbridge structure. It should not be expanding or contracting in any way, and addressing this problem is a big factor when it comes to weighbridge truck scale technical design.
Whether to be used as rail car scale or mining truck scales, a properly working weighbridge can simplify the task of weighing items, which is critical for a lot of businesses. To maintain a weighbridge truck scale investment, it is essential to understand the advanced weighbridge technology that guides the design weighbridge. Hopefully this short introduction has armed you with some of the necessary knowledge.
