Summary:A rotor hub 100 for a wind turbine may generally include a hub body 102 defining both a plurality of blade flanges 112 and a plurality of access ports 120 spaced apart from the blade flanges. In addition, the rotor hub 100 may include a ladder assembly 200 extending within an interior of the hub body. The ladder assembly 200 may include a plurality of platforms 202,204,206, with each platform defining a planar surface 216 and being circumferentially aligned with a respective one of a plurality of access ports 120. The ladder assembly 200 may also include a connecting frame 226 extending between each pair of adjacent platforms 202,204,206 so as to couple the adjacent platforms to one another. The connecting frame 226 may extend lengthwise along a reference line defined between the adjacent platforms. The platforms 202,204,206 may be positioned relative to one another such that the reference line extends at a non-perpendicular angle relative to the planar surfaces defined by the adjacent platforms.
