Primary Applications
- Overheight vehicle detection
- Bridge and overhead structure protection
- Temporary construction clearance warnings
- Automated diversion and warning systems
Deployment Options
- SPTT-3000 Tower Trailers
- Compatible message boards and beacon trailers, depending on system design
A vehicle detection system designed to identify oversized or overheight vehicles approaching restricted-clearance areas, such as overhead construction, bridges, or temporary roadway obstructions.
A detection system is installed upstream of the restricted-clearance area. When a vehicle exceeding the configured height threshold interrupts the detection beam, the system automatically activates connected warning equipment, which can include changing message boards to warn the driver of the height restriction, activating flashing beacon trailers, and directing the approaching vehicle toward an appropriate exit or alternate route.
Our detector is the Trigg Industries Single Eye (SE-IR/3311-24): a single-direction infrared source and detector pair. It triggers an alarm output whenever the beam is interrupted.
SolarTech provides integrated sensing and traffic management solutions, not just individual sensors. Depending on your needs, we can integrate sensors into existing SolarTech equipment or provide a dedicated solar-powered trailer with the necessary communications, power supply, and mounting hardware. Use them for basic traffic data collection and monitoring, for remote surveillance, or integrated with SmartZone to automate traffic safety equipment based on changing roadway conditions.
