In known devices for galvanic deposition of metal from electrolyte onto goods, wherein a galvanic drum contains electrolyte within a tank, the removal of metal undesirably deposited on the cathode contact or the replacement of used up cathode contacts from the drum has been very time-consuming and presented a contamination problem since these operations required opening of the galvanizing tank. The invention concerns a contact replacement or cleaning arrangement which can be done simply and does not necessitate undue exposure to ambient of the tank, since the used contact is removed within the tank and replaced by opening only a narrow passage through a galvanic drum axle.
