Subsequently, the compensation tensioning means 36 passes over the displaceable deflection roller 73 and back down to the stationary deflection roller 42 on the floor 10.

Abstract

L'invention concerne un procédé pour construire, dans un bâtiment, une installation d'ascenseur (1) qui comprend un moteur d'entraînement d'ascenseur (4), une cabine d'ascenseur (5), un contre-poids (6) et au moins un moyen de suspension (7) souple. Selon le procédé, au moins une opération de levage est effectuée en vue d'adapter une hauteur de levage (15) utile de l'installation d'ascenseur (1) à une hauteur croissante du bâtiment. Lors d'une opération de levage, une plateforme d'entraînement (16) qui supporte le moteur d'entraînement d'ascenseur (4) ainsi que, par le biais du moyen de suspension (7), la cabine d'ascenseur (5) et le contre-poids (6), est levée. Selon le procédé, grâce à un moyen de traction de compensation (36) qui est guidé à partir d'un côté inférieur de la cabine d'ascenseur (5) par le biais d'un dispositif de renvoi (35) jusqu'à un côté inférieur du contre-poids (6), une différence entre un poids de moyen de suspension (FA) côté cabine d'ascenseur et un poids de moyen de suspension (FG) côté contre-poids du moyen de suspension (7) est sensiblement compensée, le dispositif de renvoi (35) comportant deux ensembles poulies (45, 49) comprenant au moins respectivement une poulie de renvoi (41, 42, 43, 44 ; 41, 42, 43 44, 70, 71, 72, 73), ledit au moins un moyen de traction de compensation (36) étant guidé par le biais d'au moins respectivement une poulie de renvoi des deux ensembles poulies (45, 49) de telle sorte qu'il forme au moins une boucle de moyen de traction de compensation (40) dans laquelle une quantité prévue du moyen de traction de compensation (36) est stockée, et une distance entre les deux ensembles poulies (45, 49) étant réduite avant et/ou pendant l'opération de levage, afin qu'une quantité, nécessaire pour effectuer l'opération de levage, du moyen de traction de compensation (36) soit libérée à partir de ladite au moins une boucle de moyen de traction de compensation (40).
