    摘要： A cathode assembly is provided that enables simplifying the work of connecting a cathode block with a collector bar. A cathode assembly (100) is a cathode assembly used in an electrolytic furnace for aluminum smelting, including: a cathode block (10) made of carbon and having a groove (10a); and a collector bar unit (20) inserted into the groove (10a), wherein the collector bar unit (20) includes: two collector bars (21) and (22) made of a metal and shaped to extend in the same direction as the groove (10a) and arranged in the width direction of the groove (10a); and a spacing adjustment member (23) that adjusts the spacing between the two collector bars (21) and (22), the spacing adjustment member (23) including a mechanism that adjusts the spacing between the two collector bars (21) and (22) using threads.

    摘要： An anode servicing assembly (30, 35) for an aluminium electrolysis plant, said aluminium electrolysis plant comprising at least one line (L1, L2) of electrolysis cells (C1-Cn, C'1-C'n) connected in series, each cell having a plurality of anode assemblies (5) connected to an anode beam,
    said anode servicing assembly comprising:
    - an elongated body (31),
    - running means adapted to allow movement of said elongated body along a running direction, substantially parallel to main axis of said line (L1, L2),
    - an anode servicing machine (32) mounted on said elongated body, said anode servicing machine comprising
    o at least two operating devices (45, 55, 65, 75, 85, 95), each adapted to fulfil at least one specific function different from cell lifting and anode beam raising,
    o at least two support assemblies (40, 50, 60, 62, 70, 72, 80, 81, 82, 83, 90, 91, 92, 93), each adapted to support a respective operating device with respect to said elongated body,

    said operating devices (45, 55, 65, 75, 85, 95) being movable independently the one with respect to the other, along at least one of a longitudinal axis (L31) of said elongated body (31) and a vertical axis (ZZ).
