The RAM Series have been developed to prevent strikes and collisions against roads infrastructures such as bridges, tunnels, underpasses.

In fact, Infrastructure strikes are costly to both highway and road network operators; creating hours of delay and disruption. Therefore, it is mandatory to have an accurate system that warns drivers in advance if their vehicles exceed the maximum height approaching overhead structure.

Technical Features:

RAM 11 is based on two single beam lasers, with a high detection frequency (up to 1KHz) and a narrow angle to detect small objects.
The light emitted is reflected in order to be recognized by the receiver filtering the environmental light noises. The lasers are positioned horizontally in order to detect the vehicle travel’s direction.

It is important to highlight that RAM11, compared to RAM01, strongly reduces false alarms.

Installation:
RAM11 is installed on the road’s side and can detects overheight vehicle on 3-4 lanes and operates under night and day conditions.

Advantages of RAM11:

Compared to systems based on photocells with transmitter and receiver, the RAM series have the advantage of easy installation as they are placed at the road’s side; and they don’t need to collimate transmitter and receiver.

Alarm
RAM11 provides alarms in different ways when an over height vehicle is detected:

• relay contact
• digital output
