Abstract

Dispositif pour la manutention des différents éléments d'une installation d'injection d'air préchauffé dans un four à cuve. Il est conçu pour être associé temporairement, au moyen d'un bras de levage 72 à un chariot automoteur 60 à usages multiples et il est pivotable autour d'un premier axe vertical alors que l'ensemble constitué par le bras de levage 72 et le dispositif de manutention 70 est pivotable autour d'un second axe vertical distinct du premier. Application au remplacement d'un porte-vent et d'une tuyère.Device for handling the various components of an installation for injecting preheated air into a shaft furnace. It is designed to be associated temporarily, by means of a lifting arm 72 with a self-propelled trolley 60 with multiple uses and it is pivotable about a first vertical axis while the assembly consisting of the lifting arm 72 and the handling device 70 is pivotable about a second vertical axis distinct from the first. Application to the replacement of a wind-holder and a nozzle.
