Title
(EN) METHOD AND ARRANGEMENT ON EXTRACTING,REELING UP,PULLING IN,ETC.,OF A HEAVY CABLE OR SIMILAR
(FR) PROCEDE ET DISPOSITIF D"EXTRACTION, BOBINAGE, INTRODUCTION, ETC. D"UN CABLE LOURD OU AUTRE
Abstract
(EN)
On extracting, reeling up, pulling in etc., of a heavy cable (7) a main frame (10) that can be set up or that may already be present on a vehicle (1, 2) may be used, the said main frame comprising a base unit (10a) made up of a number of beams, and two bearing brackets (10b) projecting upwards from its long sides. A drum for the said cable is supported free to rotate on the bearing brackets. The drum (11) is provided with drive gear (13) which comprises a motor unit and a transmission component (14). Pulling device (17) is connected to a core of the cable and to a pull-free mechanism (16) secured to the main frame. By means of the pull-free mechanism the cable (7) can be given a small longitudinal displacement which enables the cable to be pulled free of its duct (6). After pulling free the pulling device is disconnected and the said core is pulled up towards and anchored on the drum, after which the motor unit is operated to turn the drum. The major part of the longitudinal displacement of the cable is then achieved by reeling the cable directly up on to the drum (11).
(FR)
Pour extraire, bobiner, introduire etc., un cable lourd (7) on peut utiliser une structure principale (10) qui est montee au sol ou sur un vehicule (1, 2), cette structure principale comprenant une unite de base (10a) constituee de plusieurs poutres, et deux consoles portantes (10b) se projetant vers le haut a partir de ses cotes longitudinaux. Un tambour pour le cable est supporte en rotation libre sur les consoles portantes. Le tambour (11) est pourvu d"un engrenage de transmission (13) qui comprend un moteur et un organe de transmission (14). Un dispositif de tirage (17) est connecte a l"ame du cable et a un mecanisme de tirage (16) fixe a la structure principale. A l"aide du mecanisme de tirage on peut deplacer sur une petite longueur le cable (7), qui peut etre extrait de sa gaine (6). Apres extraction, le dispositif de tirage est deconnecte et l"ame du cable est tiree vers le tambour et ancree sur celui-ci, apres quoi le moteur est mis en action pour mettre en rotation le tambour. La majeure partie du deplacement longitudinal du cable est ensuite effectuee en embobinant le cable directement sur le tambour (11).
