WL 400

HAENNI WL 400 Wheel Weighbridge – Slimline, Mobile Measuring Solution

The HAENNI WL 400 wheel weighbridge combines proven HAENNI technology with the latest technical developments, revolutionizing mobile axle load measurement. This extremely lightweight and slim sensor offers an ideal solution for flexible on-site measurements, while also being excellently applicable in toll systems and freight management applications for stationary installations.

The WL 400 offers the perfect balance between portability and precision, enabling authorities, industrial stakeholders, and research institutes to quickly and accurately check vehicle axle loads.

Key Features and Advantages

The main strength of the WL 400 strip scale lies in its unparalleled mobility, ensured by its extremely low weight and slender profile.

• Easy Portability: The standard system weight is only about 80 kg, guaranteeing unparalleled mobility during on-site setup. This significantly facilitates the quick erection and dismantling of enforcement checks.
• Slim Profile: The sensor's extremely low height of only 11 mm minimizes the level difference that occurs when vehicles drive over it, thereby increasing safety and user comfort.
• Dynamic Measurement: The WL 400 is specifically optimized for dynamic measurements, enabling axle load checks in motion, up to a speed of 20 km/h.
• Flexible Application: Although primarily positioned as a mobile solution, the WL 400 is also suitable for stationary installation, for example, as part of toll systems or freight management systems.
• Reliable HAENNI Technology: The product is built upon HAENNI's decades of experience, guaranteeing long-term reliability and precise measurement results.

Technical Data

The precise and detailed technical specifications of the WL 400 strip scale ensure efficient and authentic measurement under the most varied conditions.

System Components and Compatibility

The WL 400 strip scale cannot process measurement data on its own. To build the complete system, compatible processing units and software are required:

• Processing Unit: EC 120
• Software: EC 200 Processing Software

These units ensure the real-time processing, display, and recording of data collected by the sensors, supporting various measurement solutions (e.g., static or dynamic axle-by-axle measurement).

Application Areas

Due to the versatility of the WL 400, it can be widely applied in critical areas of weight control:

1. Official Inspections: Ideal for traffic enforcement agencies for fast and reliable axle load control, helping to protect road infrastructure and maintain traffic safety.
2. Industrial Application: In logistics hubs, construction sites, or quarries for optimizing vehicle loads and ensuring compliance with internal regulations.
3. Research and Development: Support for testing the dynamic behavior of vehicles, tire loads, or running gear.
4. Exceptional Dimensions Handling: Checking the weight of large or oversized shipments to guarantee the safety of transport routes.

Documentation and Support
