Abstract

Le dipsositif de guidage a pour but de guider le câble sous charge pendant son enroulement autour d'une poulie qui est entraînée en rotation, soit manuellement soit au moyen d'un dispositif moteur. Ledit dispositif est fondamentalement applicable à des appareils utilisés pour monter et descendre des charges verticalement, sans écarter d'autres applications. Le dispositif de l'invention améliore l'enroulement du câble sur la poulie, laquelle sert de poumon pour le câble métallique sous tension qui travaille en traction. Le dispositif de guidage comprend un corps de révolution qui présente une surface latérale au niveau de laquelle sont définies des canalisations annulaires en combinaison avec des parties saillantes et des crêtes excentriques.
