- the electrolytic cells 100 such as those shown in FIG. 1, conventionally comprise a box 102 of steel inside which a coating of refractory materials is arranged, a cathode 104 made of carbon material, crossed by conductors cathodes for collecting the electrolysis current at the cathode 104 to lead cathodic outputs through the bottom or sides of the box 102, routing conductors extending substantially horizontally to the next tank since the cathodic outputs, an electrolytic bath in which the alumina is dissolved, at least one anode assembly comprising at least one anode 110 immersed in this electrolytic bath and an anode rod 108 sealed in the anode 110, an anode frame 112 to which is suspended the anode assembly via the anode rod, and electrolytic current rise conductors, extending from bottom to top, connected to the pipe
- the electrolytic flow of the preceding electrolysis tank 100 for conveying the electrolysis current from the cathode outlets to the anode frame and the anode assembly and
- a sheet 114 of liquid aluminum is formed at the bottom of the electrolytic cell.
- the liquid aluminum thus produced is regularly collected in casting containers, also called ladles. The liquid aluminum thus collected is then transported to a foundry for treatment.
- the transport of empty or full cast containers is traditionally provided by a first type of transport vehicle.
- This first type of vehicle conventionally comprises, as can be seen in FIG. 2, a vehicle 120 before pulling with cabin 121, which is coupled to a articulated trailer 122 capable of support a pouring vessel 124 full of liquid aluminum collected in several electrolysis tanks.

- the bar forming the partial load transfer member 10 has two bearing ends 14 each forming one of the bearing portions.
- the elastic member or members 12 connecting the bar to the platform 6 are then arranged substantially symmetrically with respect to the longitudinal median plane of the platform 6.
- the bearing ends 14 advantageously pass through windows 16 provided in each longitudinal side of the platform 6.
- the platform 6 may comprise immobilization means movable between a retracted position (not shown) in which the immobilization means allow the platform 6 to be rolled over its plurality of wheels 60 and an extended position (FIG. 7) in which the immobilizing means prevent the platform 6 from rolling on its plurality of wheels 60.
- the immobilizing means comprise friction means 64 for rubbing against the ground.
- the immobilizing means may comprise a brake intended to block the rotation of at least one of the wheels 60 among the plurality of wheels of the platform 6.
- the platform 6 may comprise connecting means connecting the immobilizing means to the elastic member 12, to subordinate the immobilization of the platform 6 to partial load transfer.
- These connecting means comprise, for example, a substantially vertical bearing foot 66 whose proximal end is terminated by the friction means 64 and a distal end of which is connected to the elastic member 12, for example via the transfer member 10 partial charge which it can be solidary.
- the friction means 64 may comprise a plurality of claws for hooking the ground on which the platform 6 rests under the effect of the compression of the elastic member 12.
- the foot 66 may be arranged in the extension of the elastic member 12 for maximum force transmission.
- the connecting means and the elastic member 12 can be configured so that the elastic member 12 tends to maintain the immobilizing means in the deployed position.
- the traction machine 8 may comprise a U-shaped loading portion into which the platform 6 is intended to be inserted.
- This U-shaped loading portion comprises two substantially parallel lateral portions 86 and connected by a central portion 88 which can form the front of the traction machine 8.
- the hitching means can then comprise two first 62 coupling elements arranged on each longitudinal side of the platform 6 and two second coupling elements 80 arranged on the lateral branches 86 of the loading portion to cooperate by complementary shape with the first hitch elements 62.
- the L-shaped brackets 82 may each be attached to one of the side portions 86.
- Their receiving surface 84 extends inside the U formed by the loading portion.
- the support means comprise forks
- these forks may extend inside the U formed by the loading portion, between the two portions 86 laterally from the central portion 88.
- the forks may further comprise notches forming the second coupling elements 80 and shaped to cooperate with lugs forming the first coupling elements 62.
- the traction gear 8 is advantageously single-body or single-frame.
- the traction machine 8 comprises wheels 90 arranged under each of the lateral portions 86 and under the central portion 88, for maximum stability, and to avoid any overhang associated with a necessary counterweight and allow it to move under load. and empty.
- the traction machine 8 is a motor vehicle.
- the traction machine 8 comprises one or more electric motors. This or these electric motors can be powered by a set of supercapacitors 94. These supercapacitors 94 may be uniformly distributed in all portions of the traction machine 8, as shown in FIG. 8.
- the traction machine 8 comprises automatic guiding means for allowing the traction machine 8 to move autonomously in the electrolysis plant.
- These guidance means may comprise for example a SLAM system (from the English “Simultaneous Location And Mapping").
- the guide means may comprise laser rangefinders, cameras, and a storage unit that can store a digitized map of the electrolysis plant and / or a route map in the form of a database.
- the handling device 1 may advantageously comprise a second support platform 7 intended to support a load such as an anode assembly 3, and the traction machine 8 comprises support means , intended to fully support the second platform 7.
- the device 1 comprises means for moving the support means for lifting the second platform 7 away from the ground.
- the means for displacing the support means of the second platform 7 are advantageously merged with the first displacement means intended to relatively move the second coupling element or elements 80 and the first coupling element or elements 62 to one another. to the others, and, where appropriate, with the second moving means for relatively moving the support means and the platform 6 towards each other.
- the support means of the second platform 7 may comprise the two receiving surfaces 84 extending substantially parallel to the inside of the U formed by the loading portion along the lateral portions 86 of the loading portion. .
- the second platform 7 is intended to transport the anode assembly 3. It may comprise for this purpose means for holding the anode assembly 3 to retain the latter and thus prevent the anode assembly 3 from slipping and falling.
- the holding means can correspond to peripheral flanges 71 protruding from a support surface of the second platform 7 and delimiting with this support surface a holding cavity in which is to be placed the anode assembly 3.
- the second platform 10 may comprise a gripping surface 73 arranged to be at a distance from the ground when the second platform 7 rests on the ground, and, as can be seen in FIG. 11, the support means are intended to support the second platform 7 by bearing against the gripping surface 73, while the lifting means are intended to raise or lower the support means relative to the ground between a low position in which the support means are able to be positioned under the surface 73 and a high position in which the support means are adapted to support the second platform 7 at a distance from the ground as in FIG. 11.
- the gripping surface 73 can therefore bear against the receiving surface or surfaces 84 to enable the traction machine 8 to carry the second platform 7 with the anode assembly 3.
- the second platform 7 may be devoid of wheels.
- an aluminum plant comprising a handling device 1 as described above.
- This platform 6 may include all or part of the features described above.
