Abstract

L'invention concerne un dispositif de guidage de câble (11) pour un treuil à câble doté d'un tambour de câble (1) pouvant tourner autour d'un axe (9) pour enrouler ou dérouler un câble (4), un élément de guidage pourvu de plusieurs galets de guidage de câble (17a, b) pouvant être déplacé parallèlement à l'axe du tambour de câble. Ce dispositif de guidage de câble est de structure simple et robuste, peut être adapté à des treuils à plusieurs couches, ne nécessite aucune opération d'ajustement et amortit cependant les vibrations dans le câble. Une masse supplémentaire est incorporée sans jeu, radialement au câble, dans le tronçon de câble qui se trouve avant le tambour de câble, afin de supprimer efficacement les vibrations du câble dans la zone de sa fréquence propre. La masse incorporée est la masse de l'élément de guidage lui-même, guidé en montage flottant ; elle peut être modifiée en fonction des conditions d'exploitation par des poids supplémentaires pouvant être fixés de manière amovible à l'élément de guidage.
