Abstract
A handling device for hoods of an aluminum production cell by fused bath electrolysis, including a positioning device and a hood-gripping device. The positioning device includes a vertical guide device, a mobile support mounted on the guide device so that it can be moved in at least a vertical direction during use, an articulated arm, a first framework mounted on the articulated arm so that it can pivot about a first rotation axis A substantially horizontal during use, a motor to make the first framework pivot about the first rotation axis A, a second framework mounted on the first framework so that it can be moved along the first translation axis B that is substantially horizontal during use, and means of displacing the second framework along the first translation axis B. The hood-gripping system is fixed to the second framework and includes a set of gripping devices designed to grip a set of hoods at a number of fixing points.
