Wheel and Axle Weighing
Portable Wheel and Axle Weighing for Vehicle Load Verification
Wheel and axle weighing systems provide a practical solution for measuring individual wheel loads, axle weights, and total vehicle weight without the need for a full-size weighbridge installation. These systems are commonly used for overload prevention, compliance checks, fleet management, temporary weighing operations, and vehicle weight verification across industrial and transportation environments.
Designed for portability and ease of deployment, wheel and axle weighing systems can be used at fixed sites or moved between locations as operational requirements change.

Specifications may vary depending on system configuration, application requirements, and vehicle type.
Weighing Modes: Static vs. In-Motion
Static Weighing
Static weighing is performed by positioning each axle or wheel set on the weighing pads while the vehicle remains stationary. Individual axle weights are measured and combined to calculate the total vehicle weight. This method provides the highest level of weighing accuracy and is commonly used for compliance checks, enforcement activities, and legal-for-trade applications.
In-Motion Weighing
In-motion weighing allows vehicles to pass over the weighing pads at low speed without stopping completely. The system automatically records axle weights and calculates total vehicle weight while maintaining vehicle flow. This approach is often used where higher vehicle throughput is required and minor variations in weighing accuracy are acceptable.
Standards, Certifications and Compliance
Wheel and axle weighing systems can be supplied to support recognized weighing and metrology requirements applicable to vehicle weight verification and compliance activities.
Relevant standards may include:
- OIML R76 for non-automatic weighing instruments
- OIML R134 for vehicle weighing applications
- CE-M / NAWI compliance where applicable
- Regional conformity requirements including GCC and Saudi market requirements
- Calibration and verification procedures aligned with legal metrology practices
For regulated applications, periodic calibration and verification may be required to maintain measurement accuracy and compliance with local authority requirements.
