Abstract

Le dispositif comprend une tête 22 dans laquelle sont prévus plusieurs jeux de poulies. Un porte-lampes annulaire 24, comportant plusieurs organes de fixation d'ampoules, est suspendu à la tête 22 par plusieurs câbles 33, 35, 37 et 39 associés à plusieurs poulies. Ces câbles sont reliés à un treuil principal des organes de liaison intermédiaires qui compensent les différences de longueur desdits câbles et permettent au porte-lampes de << flotter >>. Des organes sont également prévus pour commander la tension sur le câble principal 100 du treuil, ce qui permet d'empêcher des accidents dus à un relâchement indesirable du câble ou à une mauvaise mise en place de ce câble sur le déviroir 96 du treuil. Des organes de verrouillage d'un type nouveau sont également prévus pour soulager les câbles de suspension de leur charge lorsque le porte-lampes se trouve au sommet du poteau, dans sa position normale de fonctionnement. Application à l'entretien et à la réparation de poteaux d'éclairage de très grande hauteur.The device comprises a head 22 in which several sets of pulleys are provided. An annular lamp holder 24, comprising several bulb fasteners, is suspended from the head 22 by several cables 33, 35, 37 and 39 associated with several pulleys. These cables are connected to a main winch of the intermediate links which compensate for the differences in length of said cables and allow the lamp holder to "float". Organs are also provided for controlling the tension on the main cable 100 of the winch, which makes it possible to prevent accidents due to undesirable slackening of the cable or to improper positioning of this cable on the winder 96 of the winch. Locking members of a new type are also provided to relieve the suspension cables of their load when the lamp holder is at the top of the post, in its normal operating position. Application to the maintenance and repair of very high lighting poles.
