Abstract

La présente invention concerne un ascenseur comprenant un dispositif pour amortir les vibrations sur la cabine d'ascenseur (1). Au moins une barre de traction (5) de la suspension est équipée d'un capteur (6) conçu sous forme de cristal piézo-électrique. Le cristal piézo-électrique produit un transfert de charge en cas de modification des forces de câble. Ce transfert de charge est amplifié au moyen d'un amplificateur de charge (7). Le signal de l'amplificateur de charge alimente une bobine (8) qui entoure la barre de traction (5). Cette barre de traction (5) est constituée au moins partiellement d'une matière magnétostrictive. En cas de modification de forces dans la barre de traction (5), un signal produit par le capteur (6) ou par l'amplificateur (7) induit un changement de longueur dans la partie magnétostrictive (5.1) de la barre de traction (5) au moyen de la bobine (8). Ce changement de longueur compense la modification de forces mesurée auparavant.
