1. A planetary gearbox device comprising:
a static ring gear,
a rotatable planet carrier,
a plurality of planet gears, each of the planet gears being connected to a respective bearing device,
wherein at least one of the bearing devices is coupled to at least one lubricant scooping device and/or at least one lubricant reservoir device for collecting lubricant coming from the at least one of the bearing devices, the at least one lubricant scooping device and/or at least one lubricant reservoir device being positioned at a first radial position of the planetary gearbox device; and
at least one lubricant channel arranged to direct a flow of the collected lubricant radially inwardly towards a lubrication location and/or a lubricant supply for the at least one of the bearing devices, where the lubrication location and/or lubricant supply is positioned at a second radial position of the planetary gearbox device, the second radial position is radially inward of the first radial position.
