Collision Avoidance

Gigasense Anti-Collision function

Gigasense anti-collision system controls and protects track bound cranes and similar machinery, controlling distance, speed and direction. Each unit A and B consists of an active antenna and a relay box. The antenna sends a microwave signal to the opposite system. By using Doppler technique, the distance, speed and movement can be controlled and managed via the relay box. There are 3 relays in the relay box:

  • Relay 1 = Warning (speed reduction).
  • Relay 2 = Stops crane movement.
  • Relay 3 = Function control.

Gigasense Anti-Collision safety

Gigasense anti-collision system / collision avoidance system protects people and property. The system has a built in self diagnostic function that monitors the system performance every three seconds.
