Patent number: 10487581Abstract: A rotor hub for a wind turbine may generally include a hub body defining both a plurality of blade flanges and a plurality of access ports spaced apart from the blade flanges. In addition, the rotor hub may include a ladder assembly extending within an interior of the hub body. The ladder assembly may include a plurality of platforms, with each platform defining a planar surface and being circumferentially aligned with a respective one of the plurality of access ports. The ladder assembly may also include a connecting frame extending between each pair of adjacent platforms so as to couple the adjacent platforms to one another. The connecting frame may extend lengthwise along a reference line defined between the adjacent platforms. The platforms 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.Type: GrantFiled: February 24, 2017Date of Patent: November 26, 2019Assignee: General Electric CompanyInventors: Chengjie Wang, Mohan Muthu Kumar Sivanantham, Vidya Sagar Meesala
