Abstract

L'invention concerne un dispositif pour poser des lignes de transport d'énergie dans un chemin de câbles muni d'une pluralité de supports, ce dispositif comprenant : des moyens de préhension agencés sur le chemin de câbles ; et des moyens d'entraînement, qui sont agencés sur une pluralité de points sur le chemin de câbles de manière à être synchronisés avec les moyens de préhension, pour tirer des lignes de transport d'énergie par l'intermédiaire d'un mouvement de va-et-vient d'un actionneur, ce qui permet d'obtenir une structure légère, mince, petite et compacte pendant l'installation dans un endroit où il est difficile de travailler, tels que des chemins de câbles sur des navires et dans des dépôts maritimes, en raison de l'accès limité et du positionnement difficile du corps des personnes intervenant, et ce qui permet de réduire le nombre de personnes requises et de raccourcir la durée du travail de pose des lignes de transport d'énergie.
