BISON Weigh In Motion
Model Low Speed CONTROL

Model Low Speed CONTROL

Bison LS Control is an advanced dynamic weighing system designed by IWIM Srl, a Trentino-based company with over 15 years of experience in monitoring and ensuring the safety of infrastructures such as roads, bridges, and viaducts.
This system provides continuous monitoring of vehicles at speeds of up to 25 km/h, delivering precise weight measurements independent of external conditions. It optimizes logistics management through access control, daily reports, and alerts for unauthorized license plates.
Compatible with ANPR and LIDAR cameras, Bison LS Control ensures comprehensive monitoring and integrated security.
The installation is simple and smart, featuring a prefabricated reinforced concrete structure and the exclusive use of fiber optic cabling.
The system offers detailed traffic and load analysis, monitoring of overload recurrences and exceptional transport, as well as customized statistical data for efficient and targeted management.
