Abstract

L'invention concerne un ascenseur sans local de machinerie dans lequel est intégré un régulateur (4) et dans lequel un stoppeur de câble (3) situé du côté cage est maintenu par un rail de guidage (2). Etant donné qu'un composant (18) destiné à être monté sur le rail de guidage (2) peut être partagé entre le régulateur (4) et le stoppeur de câble (3), on peut obtenir un régulateur relativement peu coûteux et réduire la main-d'oeuvre requise pour son installation.
