CA 2401141
The invention relates to a working device (2) which is attached to a surface (1) by a pull of negative pressure, can be displaced on said surface, in particular for carrying out work and is connected to a base station via a supply line (4). With said device, there is a risk that if the pull diminishes, the working device (2) may fall. To prevent this, the invention is characterised in that the working device (2) is connected to the base station (3) by means of a safety line (5) that can be used to prevent the working device (2) from falling. The working device (2) can therefore also be used in places, from which it could fall from a great height if said device malfunctioned, such as for example, on the exterior of buildings.
Un dispositif de travail (2), qui est attiré par dépression contre une surface (1) sur laquelle il peut se déplacer pour la réalisation de travaux et qui est relié à une station de base par l'intermédiaire d'une conduite d'alimentation (4), présente le risque de tomber en cas de diminution de la force d'attraction. Afin de remédier à cet inconvénient, l'invention est caractérisée en ce que ledit dispositif de travail (2) est relié à la station de base (3) par l'intermédiaire d'une corde de sécurité (5), qui peut empêcher le dispositif de travail (2) de chuter. Ledit dispositif de travail (2) peut ainsi être utilisé dans des lieux où il pourrait sinon tomber de hauteurs très importantes en cas de panne, comme, par exemple, sur des bâtiments à l'extérieur.
