A weighbridge consists of a robust and durable platform structure that can support the weight of vehicles. It is usually made of steel or concrete, designed to withstand heavy loads and provide a stable weighing surface.
Load cells are sensors embedded within the weighbridge structure that measure the weight placed on the platform. These cells convert the applied force into electrical signals, which are then used to calculate the weight of the vehicle.
The load cells are connected to a weighing mechanism or indicator, which is responsible for collecting and processing the weight data. The weighing mechanism can be analog or digital and is typically located in a control room or mounted on a column near the weighbridge.
pit-mounted, surface-mounted, portable, and weigh-in-motion systems
To allow vehicles to access the weighbridge platform smoothly, ramps or approach plates are installed on either side of the platform. These provide a gradual incline or decline for vehicles to move onto and off the weighbridge.
Weighbridges often incorporate traffic control equipment such as traffic lights, barriers, and signage to direct vehicles and ensure a controlled flow of traffic during weighing operations. This helps in maintaining safety and order at the weighbridge site.
To ensure the safety of operators and vehicles, weighbridges may have safety features like non-slip surfaces on the platform, guardrails, and adequate lighting. Additionally, safety protocols and procedures should be in place to prevent accidents and ensure compliance with occupational health and safety regulations.
Weighbridge installations often consider environmental factors, such as rainwater drainage systems and measures to prevent soil erosion or contamination, to protect the surrounding environment.
Regular calibration and maintenance of the weighbridge equipment are necessary to ensure accurate and reliable weighing results. Calibration involves verifying and adjusting the weighing system to maintain its accuracy within acceptable tolerances.
Prime’s weighbridge consists of a sturdy platform, known as the weighbridge platform, constructed using reinforced concrete or steel. Load cells, which are sensors placed strategically beneath the platform, measure the force or weight applied by the vehicle. These load cells, typically made of materials like steel or aluminum, use strain gauges to convert the applied force into an electrical signal. The electrical signals from the load cells are collected and processed in an electronic junction box, which serves as a central point for signal aggregation and calibration. The junction box is connected to each load cell, and it ensures accurate measurement of the vehicle’s weight. The load cell signals are then summed up and processed to calculate the total weight.
To provide an interface for users, Prime’s weighbridge includes an indicator. The indicator displays the weight readings and allows the operator to interact with the system. It typically features a digital display, control buttons, and various settings for configuring the weighbridge operation. Before weighing, the vehicle is driven onto the weighbridge platform, ensuring that all the vehicle’s axles are fully supported. Once the vehicle is correctly positioned, the load cells measure the force or weight applied by the vehicle. The load cell signals are transmitted to the electronic junction box, where they are processed and summed up to calculate the total weight accurately.
To maintain accuracy, weighbridges need periodic calibration using known weights. This calibration process adjusts the load cell readings to match the actual weight standards. By periodically calibrating the system, accurate and reliable weight measurements can be ensured.
Prime’s weighbridge systems include software for data management. This software records and stores the weight measurements along with other relevant information, such as vehicle identification, date, and time. It can generate reports, perform data analysis, and integrate with other business systems to facilitate efficient management of weighing operations.
