摘要

The unit for operating an aluminum production plant comprises a lifting system that includes: - an upper portion (112) secured to a movable carriage of the plant; - an intermediate portion (113) which can move relative to the upper portion along a vertical upper guiding axis (114) and which supports a first tool (101) that can intervene in a first operational region (161) when the intermediate portion is in the bottom position; - a lower portion (115) which can move relative to the intermediate portion along a vertical lower guiding axis (116) and which supports a second tool (120) that can intervene in a second operational region (162) when the lower portion is in the bottom position. The operational regions are located at a distance from one another in the (X, Y) directions, and the first operational region is higher than the second operational region in the (Z) direction.
