Aggregate Scales and Onboard Weighing Systems

Onboard aggregate scales use sensors mounted on a truck or trailer suspension or frame to estimate vehicle weight as material is loaded. A cab display or handheld device presents gross, net, and axle-group weights, depending on the system configuration. This lets operators check load status at the site rather than relying solely on a fixed public or commercial scale.

Yes. By showing weight during or after loading, an onboard system helps drivers and loaders make informed adjustments before a truck leaves the yard, quarry, or jobsite. TruckWeight Analytics can also provide overweight events and records for fleet oversight. Final compliance responsibilities and any required certified scale verification remain subject to applicable regulations and operating practices.

TruckWeight systems are designed for commercial trucks, tractors, and trailers, including vehicles with mechanical or air-ride suspension configurations. Sensor choices include strain gauges for spring suspensions and air-suspension sensor technology. Suitability depends on the vehicle configuration, operating environment, and the weights a fleet needs to monitor, such as gross, net, or axle-group weight.

TruckWeight’s Smart Data Pipeline is designed to integrate onboard scale data with cloud platforms and telematics APIs. It supports real-time access and dissemination through technologies including Google Firestore, BigQuery, and PubSub. Integration planning should confirm the destination platform, desired data fields, reporting needs, and how drivers, dispatchers, maintenance teams, and compliance personnel will use the information.

Calibration aligns sensor readings with known vehicle weights so the system can provide useful operating data. TruckWeight offers Full Remote Calibration, a cloud-based approach for calibrating sensors and configuring systems from a remote location. A sound process includes using reliable reference weights, documenting settings, checking readings after equipment changes, and recalibrating when performance indicates it is needed.

TruckWeight offers rugged, weatherproof onboard scale options intended for demanding commercial fleet use. Available technologies include air-suspension sensors, strain gauges, and MG-3 military-grade sensors. The best selection depends on suspension type, loading cycle, exposure to dust or moisture, and maintenance expectations. Proper installation and periodic performance checks help protect dependable day-to-day weight monitoring.

TruckWeight Analytics can store, share, verify, record, report on, and analyze truck and trailer weight data. Features include live data access, overweight alerts, auditable safety records, remote sensor calibration, and centralized monitoring of multiple trucks and sensors. Fleet managers can use this visibility to support payload decisions, maintenance workflows, quality control, and compliance oversight.

TruckWeight describes its systems as self-installable and designed to require no special tools, helping avoid the wiring and electrical connections associated with traditional wired scale installations. Installation requirements still vary by truck, trailer, suspension, sensor type, and desired display configuration. Reviewing the specific equipment setup before installation helps ensure correct sensor placement and dependable operation.
