ABSTRACT:
This invention relates to pot tending module intended for aluminium production plants by fused bath electrolysis. According to the invention, the turret (9) of the pot tending module (7) is equipped with a determined set of tools, in which the tool (101, 102, 103) is mounted on a telescopic arm (111, 112, 113) fixed to the turret (9) through an articulated support (121, 122, 123) that enables pendular movements of the telescopic arm with respect to a determined articulation point while preventing rotation movements of the telescopic arm about its principal axis. The telescopic arms are connected to each other through a mechanical connecting device (200) capable of maintaining the relative angular difference between the pendular movements of the telescopic arms within a determined tolerance range. The invention enables the tools to be arranged closer to each other without any risk that they will collide during use.
