CA 2234543

In this lift a lift cage is carried by a carriage (1), which essentially consists of a drive unit (2), a support unit (3) and a respective lower yoke (4) at each side connecting the units (2, 3). The carriage (1) is movable along a respective vertical track (3) arranged at each side. The drive unit (2) consists of a motor (6), a drive axle (7) and a respective drive wheel (8) at each side, which rolls along the track (5). The support unit (3) consists of a support axle (9) with a respective support wheel (10) at each end and a clamping device (11), by means of which a friction force of the drive wheel (8) and of the support wheel (10) on the track (5) is producible. The working range of the clamping device (1) can be read off at an indicator (12). A respective fixing equipment (13) is arranged at each side at the lower yoke (4). By means of the fixing equipment (13) the lift cage can be releasably connected with the track (5) at a desired position of the travel path during assembly and/or maintenance operations.

Dans le présent ascenseur, la cabine est portée par un ensemble porteur (1) qui comprend essentiellement un groupe d'entraînement (2), un groupe de support (3) et un étrier inférieur (4) de chaque côté respectivement reliant les groupes (2, 3). L'ensemble porteur (1) se déplace le long d'un rail vertical (5) placé de chaque côté respectivement. Le groupe d'entraînement (2) comprend un moteur (6), un essieu moteur (7) et une roue motrice (8) de chaque côté respectivement, qui roule le long du rail (5). Le groupe de support (3) comprend un essieu porteur (9) avec une roue porteuse (10) de chaque côté respectivement et un dispositif de serrage (11) au moyen duquel une force de frottement de la roue motrice (8) et de la roue porteuse (10) peut s'exercer sur le rail (5). La plage de fonctionnement du dispositif de serrage (11) peut se lire sur un indicateur (12). Un équipement de fixation (13) est disposé de chaque côté respectivement au niveau de l'étrier inférieur (4). Au moyen de l'équipement de fixation (13), la cabine d'ascenseur peut être raccordée de façon amovible au rail (5) à une position souhaitée de la voie de circulation lors des opérations d'assemblage et/ou de maintenance.
