Abstract

L’invention concerne un ascenseur comprenant : une cabine (14), une courroie (20) reliée à ladite cabine (14) et s’étendant d’une poulie d’entrainement (22) à une poulie de renvoi (24) en formant une boucle fermée ; un dispositif de commande (42) pour pouvoir commander ladite poulie d’entraînement (22) à une vitesse de rotation prédéfinie. L’ascenseur comprend en outre un dispositif de mesure (54, 55) relié audit dispositif de commande (42), pour mesurer la distance parcourue par ladite cabine (14), et ledit dispositif de commande (42) est adapté à commander : d’une part ladite poulie d’entraînement (22) en rotation d’une première vitesse de rotation à une seconde vitesse de rotation, tandis que ledit dispositif de mesure (54, 55) enregistre simultanément une distance d parcourue par ladite cabine ; et, d’autre part le déclenchement d’une première alerte si ladite distance d parcourue par ladite cabine (14) est inférieure à une première distance prédéterminée. Figure à publier avec l’abrégé : Fig. 1The invention relates to an elevator comprising: a car (14), a belt (20) connected to said car (14) and extending from a drive pulley (22) to a return pulley (24) forming a closed loop; a control device (42) for being able to control said drive pulley (22) at a predefined rotation speed. The elevator further comprises: a measuring device (54, 55) connected to said control device (42), for measuring the distance traveled by said cabin (14), and said control device (42) is adapted to control: d 'on the one hand said drive pulley (22) rotates from a first rotation speed to a second rotation speed, while said measuring device (54, 55) simultaneously records a distance d traveled by said cabin; and, on the other hand, triggering a first alert if said distance d traveled by said cabin (14) is less than a first predetermined distance. Figure to be published with the abstract: Fig. 1
