Abstract

L'invention concerne un système d'ascenseur (10) comportant une cabine d'ascenseur (12), un dispositif d'entraînement (14), un moyen de transmission du type courroie (13) et deux contrepoids. Le dispositif d'entraînement (14) est fixe et le moyen de transmission, qui se présente avantageusement sous la forme d'une courroie trapézoïdale à nervures (13), coopère avec le dispositif d'entraînement (14) pour mettre en mouvement, par friction, la cabine d'ascenseur (12) par transmission d'une force. Le moyen de transmission (courroie) peut être renforcé par des fibres synthétiques, de préférence en Zylon (PBO).
