The invention relates to an extracting device (30) for extracting a short-circuiting shim inserted between two conductors (24 and 25) for switching off an electrolytic cell (2). The extracting device (30) includes a means (31) for grasping said shim and, associated with the upper horizontal surface (240, 250) of each conductor (24, 25), at least one vertically-oriented cylinder (32) including a body (320) and a rod (321), a) said rod (or said body) being rigidly connected to at least one horizontal bearing surface (335) oriented downward and arranged such that, when said extracting device is positioned above said shim in order to extract same, the upper horizontal surface (240, 250) of each conductor (24, 25) is located directly opposite a horizontal bearing surface (335), b) said body (or said rod) being connected to said grasping means (31) of said shim, such that, when said cylinder (32) is actuated in order to extract said shim, said cylinder exerts opposing forces on said conductors and on said shim, which tend to space the latter apart from one another. |
