This case study details a weighbridge upgrade project for a stone quarrying company in Sanming. The mine specializes in raw stone extraction, stone crushing, and the transportation of sand and gravel aggregates. The site primarily handles heavy-duty dump trucks, which carry large loads and pass through the weighbridge frequently. Located in a remote mountainous area, the mining site features a complex operating environment characterized by heavy dust, scattered debris, and the intense impact of vehicle unloading. Additionally, the region receives ample rainfall, leading to muddy conditions and standing water that accelerate equipment corrosion. Standard commercial truck scales have a flimsy structure; prolonged exposure to heavy loads and rolling traffic can lead to issues such as deformation of the scale body, dust and water ingress into the sensors, and erratic weight readings. These problems not only increase maintenance costs but also severely compromise the accuracy of material settlement. To strengthen material control at the mine, the client selected Fujian Fangda Weighing Instruments to replace and install heavy-duty industrial truck scales.

Taking into account the harsh operating conditions in mining environments, we have equipped our client with a 3×16-meter, 120-ton reinforced heavy-duty truck scale. The scale frame features a densely arranged structure of thickened U-shaped beams, welded into a single unit. This design ensures high overall rigidity and load-bearing capacity, enabling it to withstand repeated碾压 by heavy vehicles and the instantaneous impact of stone loading and unloading over the long term, effectively preventing issues such as frame bending and structural damage. To address common challenges in mining areas—such as high dust levels, muddy conditions during rain, and abrasion from rock materials—the scale body undergoes heavy-duty sandblasting for rust removal followed by a multi-layer anti-corrosion baked paint process. The surface is wear- and scratch-resistant, while the interior is fully sealed to provide dustproof, waterproof, and acid/alkali-resistant protection, making it suitable for the harsh operating environments of mountainous and remote areas.

The equipment is equipped with industrial-grade shock- and dust-resistant digital sensors that resist vibration and electromagnetic interference. Even under complex mining conditions, it maintains stable and accurate weighing data—free from drift or data jumps—enabling precise control over the measurement of raw stone intake and finished aggregate output, thereby ensuring fair and compliant trade settlements for the mine. As the original manufacturer, we provide one-stop on-site services, including on-site surveys of mountainous terrain, planning of drainage, foundations, and scale layout. Our professional team performs standardized installation, wiring, commissioning, and calibration, ensuring the equipment complies with national industrial metrology verification standards.

Since the weighbridge was put into operation, vehicle traffic in the mining area has flowed smoothly, equipment failure rates have dropped significantly, and operational and maintenance costs have been effectively reduced. Fujian Fangda Weighing Instruments has deep roots in the heavy industry sector of the mountainous regions of Fujian, specializing in the R&D of high-strength weighbridges designed specifically for mining. With robust manufacturing processes and stringent quality control standards, we safeguard safe production and ensure precise measurement for all types of mining enterprises.

Fujian Fangda Weighing Instruments provides a full range of electronic weighbridge from 30 tons to 200 tons
