The invention regards to a pulley device, especially turbo braking pulley device, especially designed for cableways, for gravitational transport of persons and things. The pulley device has at least one pair of blades (43, 44; 53, 54), a rotation speed of which is applied upon them by a respective pulley (30) being guided along a cableway rope (F). The rotation speed of the blades (43, 44; 53, 54) is reduced by effect of friction with air encountered as the pulley device descends a cableway span. That reduction in rotation speed is transmitted to the at least one pulley.
Cette invention concerne un dispositif à poulies, en particulier un dispositif à poulie de turbofreinage destiné spécifiquement à des téléphériques pour le transport par gravité de personnes et de biens. Le dispositif à poulie comprend au moins une paire d'aubes (43, 44; 53, 54) auquel il transfert sa vitesse de rotation par une poulie correspondante (30) guidée sur un câble de téléphérage (F). La vitesse de rotation des aubes est réduite par le frottement de l'air rencontré au fur et à mesure que le dispositif à poulie franchit en descente une portée de câble. Cette diminution de la vitesse de rotation est transmise à la poulie correspondante.
