How heavy-duty truck weighing trucks work 
Automatic translate
Cargo scales, designed for a maximum load capacity of 80 tons, have a special design that ensures accurate and safe weighing of heavy vehicles. Often referred to as weighbridges or truck scales, these scales play an important role in industries such as transportation, logistics, mining and agriculture where accurate weight measurements of large vehicles are essential for regulatory compliance, load distribution analysis and revenue calculation.. The 80 ton truck scale setup involves several key components and considerations, which we’ll cover below.
>Foundation and construction
Truck scales for heavy loads such as 80 tons require a solid foundation and a solid structure. As a rule, such scales are installed on a concrete foundation, carefully designed to evenly distribute the weight over the supporting structure. The weighing platform itself consists of a series of load cells, which are sensor devices that measure the applied load. Load cells are located along the entire length of the weight platform to accurately capture the distribution of the vehicle’s weight as it moves.
>Load cells and sensors
Load cells are an integral part of the work of truck scales. They are located under the weighing platform, often at the points of contact between the bridge structure and the supports. Load cells are designed to convert the applied load into an electrical signal, which is then transmitted to the junction box. Advanced load cell technologies such as strain gauge or piezoelectric sensors are used to ensure measurement accuracy and reliability even under varying environmental conditions.
>Junction box and signal processing
The signals from the strain gauges are collected in a junction box. This junction box serves as the central node where the signals from the individual load cells are combined. From the junction box, electrical signals are transmitted to an indicator or terminal located at a convenient distance from the weighing platform. The terminal processes and displays weight readings, often providing additional functions such as data logging, printing, and connection to external systems.
>Entrance and exit ramps
Cargo scales are equipped with entrance and exit ramps that allow cars to smoothly enter and leave the weighing platform. The ramp design is load-bearing and provides a smooth slope or descent, allowing heavy vehicles to move safely and efficiently.
>Safety Features
Safety is paramount when designing truck scales. The design incorporates features such as an anti-slip finish on the scale platform, guardrails on the sides to prevent exit from the platform, and warning signs to warn drivers to slow down and approach the scale with caution.
>Calibration and accuracy
Accurate weight measurement is critical to regulatory compliance and operational efficiency. To ensure measurement accuracy, truck scales are regularly calibrated. Calibration consists in comparing the measurement results of the balance with known standard scales. Modern calibration methods, such as the use of traceable calibration weights and digital calibration technologies, help ensure measurement accuracy.
>Environmental aspects
The environment in which the vehicle scales are located can affect their performance. Factors such as temperature fluctuations, humidity, possible vibrations from nearby sources must be considered during installation and calibration to ensure accurate readings.
The 80 ton truck scale device includes a well thought out system consisting of a solid foundation, strategically placed load cells, data processing devices, safety features and calibration mechanisms. These scales play a key role in industries where heavy loads are the norm, providing the accurate weight measurement needed for regulatory compliance, revenue calculations and load distribution analysis. Their design and layout take into account various technical aspects and safety requirements, ensuring accuracy and reliability in difficult conditions.
