A power connection device for transmitting electric power from an external power source to a working machine having an undercarriage and a superstructure, the undercarriage and the superstructure being pivotable relative to each other about a substantially vertical pivot axis, wherein the power connection device comprises
- a first power conductor member which is configured to be pivotally arranged relative to the undercarriage and the superstructure about the substantially vertical pivot axis,
- a lower attachment component configured to be attached to a upper surface of the undercarriage, and
- an upper attachment component configured to be attached to a lower surface of the superstructure, the first power conductor member being slidingly arranged between the lower and upper attachment components allowing the first power conductor member to pivot relative to the lower and upper attachment components.
