Abstract: The present invention relates to a handling clamp, designed to grasp a stem fixed to a load and equipped with at least one attachment means. The stem is capable of moving between a lower position in the handling clamp and an upper position in the handling clamp when the handling clamp is closed on the stem. When the stem is in the lower position, the handling clamp is capable of being locked closed. When the stem is in the upper position, the handling clamp is capable of being unlocked. The handling clamp of the present invention is particularly adapted for use in the aluminium industry.

Abstract: A tending module (7) for a series of electrolytic cells (2) to be used for the production of aluminum by fused bath electrolysis including a frame (8) that can be fixed to a trolley (6) and a turret (9) fitted on the frame (8) so as to pivot about a vertical axis A, and equipped with a set of tools including a crust breaker (11), a bucket shovel (12), at least one first anode clamp (13) and a hopper (15) fitted with a retractable duct (16), and a balcony or a cab (18) having controls that will be used to maneuver the module and the tools, and a control station (19) from which an operator can actuate the controls.

Abstract: The purpose of this invention is a leak limiter (20) of an electrolytic cell (1) for the production of aluminum, fitted with confinement means comprising passage openings for the insertion of anode stems (3), characterized in that it comprises at least one support (21), capable of surrounding all or part of an anode stem, and at least one flexible sealing body (30, 30a, 30b, 30c) arranged around all or part of the periphery (23) of the support (21) and designed to close off all or some of the free space between the inside edge of an opening and an anode stem (3). This invention improves the leak tightness of covering means used in electrolytic cells.

Abstract: The present invention relates to a handling device for an anode connector provided with at least two side trunnions and a tightening screw. The connector is generally capable of cooperating with attachment hooks of an aluminum production cell used in fused bath electrolysis production operations so as to enable connection of anodes onto the cell. The handling device has a tightening device capable of tightening the connector screw and affecting the tightness of the connector. The present invention also has a locking system that can lock the connector in a desired position in the handling device, by loosening the connector using the tightening device. The handling device also has at least one mobile member which typically has a support to support the connector in a closed position. The support can also displace the mobile member from its closed position to an open position, and vice versa.

Abstract: The invention concerns a clamp designed to grasp a load equipped with a stem. Locking is controlled by the presence and the position of the stem in the clamp, which avoids untimely release of the load in the event of failure of the actuating means of a mobile gripping element(s) of the clamp.

Abstract: The invention relates to a rotating mechanical and electrical connecting device (100) between a transport module (6) and handling and working devices in a fused bath electrolysis aluminium production plant, characterised in that it comprises a “fixed” frame (101) fitted with a hub (102), a sleeve (121) surrounding the hub (102) and capable of rotating about the hub, first (110) and second (120) “rotating” frames capable of rotating about the sleeve (121), sliding rotating electrical contacts (113, 114) between the frames and the drive systems (140, 141, 142, 150, 151, 152) to make the frames rotate with respect to each other about a common axis (103). The connecting device according to the invention enables a rotation with no angular limit between the three frames, while making a permanent electrical link between them.
