Truck scales are among the most critical tools for maintaining roadway safety. Another reason many states have weight regulations for commercial trucks is to minimize the vehicle’s impact and pressure on the road’s surface. In addition, manufacturers, distributors and trucking companies rely on truck scales to calculate accurate weightments to ensure proper billing.
Truck scales contain many components that work together to determine a load’s accurate weight, from the foundation and weighbridge to the load cells and Digital Indicator. Many styles exist based on specific applications, including single-axle, full-truck and multi-axle scales.
Though mechanical lever systems were common decades ago, many of today’s truck scales use load cells positioned on the weighbridges for more precise and efficient weighing. Stationary scales work well for permanent weighing sites on highways, while portable truck scales are better suited for temporary weighing applications, like construction sites and logging projects. Some heavy-duty truck scales can safely measure loads weighing up to 80,000 pounds each several hundred times a day while providing decades of service life.
Modern technology enables truck scales to perform various functions, including storing data to calculate net weights, determining daily tonnage and interfacing with software to maximize inventory management.
