The better way to warn over-height vehicles of unsafe passage

The purpose of the OVER-HEIGHT VEHICLE DETECTOR™ is to alert drivers if their vehicles are over-height for an upcoming bridge, overpass, overhead walkway etc. The OVER-HEIGHT VEHICLE DETECTOR™ is an optical instrument that uses infrared light which is invisible to the naked eye. It can operate day and night, in virtually all weather conditions, to detect vehicles that are over-height, in time for the drivers to turn back or take alternate exits or turns. With today's extremely high construction costs and downtime re-routing problems, the OVER-HEIGHT VEHICLE DETECTOR™ becomes a very cost effective alternative to even one bridge repair. The OVER-HEIGHT VEHICLE DETECTOR™ consists of a transmitter and receiver which are typically mounted on posts or poles at the same height as an upcoming overpass. The transmitter projects a narrow beam to the receiver which is located across the roadway. It can be aligned to match the exact slope of the overpass, if it is not level. "LED's" located at the top of the sensors tell the installer when the units are aligned, making setup a breeze. The sensor heads are designed so that objects less than 1 1/2" (such as antennas) will not trigger the unit. The OVER-HEIGHT VEHICLE DETECTOR™ is light weight, compact and extremely rugged. All parts are modular and can be replaced in less than 15 minutes, on site.

In urban and rural applications, the OVER-HEIGHT VEHICLE DETECTOR™ can be used, in conjunction with a light, sign, strobe or other device to alert the drivers of over-height vehicles to take an alternate route or turn back, before reaching an upcoming overpass that is too low for the vehicle.

For turnpikes and limited access highways, the OVER-HEIGHT VEHICLE DETECTOR™ can be used to inform drivers not to take certain exits that will lead to a bridge or overpass that is too low for the vehicle.

For parks and resort areas, in addition to alerting the drivers, the OVER-HEIGHT VEHICLE DETECTOR™ can be used to activate a road closing device such as a barricade or gate. The OVER-HEIGHT VEHICLE DETECTOR can be used independently or as part of the CHIPS system.
