Abstract

L'invention concerne un dispositif destiné à éviter les collisions entre des ponts roulants qui se déplacent sur les mêmes rails. Chaque pont roulant porte un émetteur d'ultrasons, un récepteur voisin de l'émetteur, un réflecteur qui réfléchit les signaux émis par un autre pont roulant et un petit réflecteur auxiliaire qui réfléchit directement les signaux émis vers le récepteur. Ce réflecteur auxiliaire permet un contrôle permanent du bon fonctionnement du dispositif. L'invention s'applique notamment à des ponts roulants de fonderies, de laminoirs, etc.The invention relates to a device for preventing collisions between overhead cranes moving on the same rails. Each overhead crane carries an ultrasound transmitter, a receiver adjacent to the transmitter, a reflector that reflects signals transmitted by another overhead crane, and a small auxiliary reflector that directly reflects signals transmitted to the receiver. This auxiliary reflector allows permanent control of the correct functioning of the device. The invention applies in particular to cranes for foundries, rolling mills, etc.
