Beschreibung
Zusammenfassung:	A rotation apparatus for a boom (1) of a mining vehicle, the apparatus comprising a rotation device (21) having an axial central axis (210) . The rotation device (21) comprises a housing (213), an inner manifold (214) having a tube-like structure with a space (212) within, wherein the inner manifold (214) is arranged concentrically inside the housing (213). The housing (213) is arranged to rotate around the axial central axis (210) and the housing (213) comprises a housing channel (215). The inner manifold (214) comprises a fluid channel (216) having a fluid inlet (217) for receiving fluid from the boom, and the fluid channel (216) is connected to the housing channel (215) for forming a fluid conduit through the rotation device.
