Abstract

L'invention concerne un système d'ascenseur dans lequel un moyen de suspension de type courroie est guidé par l'intermédiaire d'une poulie à adhérence d'un mécanisme d'entraînement et par l'intermédiaire de deux poulies de renvoi d'une cabine. Le moyen de suspension de type courroie est guidé en outre entre les deux poulies de renvoi de la cabine par l'intermédiaire d'un élément tendeur au moyen duquel le moyen de suspension de type courroie est soumis à une force. Ledit élément tendeur est agencé de manière mobile de sorte que le moyen de suspension de type courroie, en cas de réduction de la tension, soit déplacé et ainsi tendu par l'élément tendeur.
