Zusammenfassung:	An external ladder assembly for a nacelle of a wind turbine includes at least one ladder having parallel side legs and a plurality of rungs arranged between the parallel side legs. The ladder assembly also includes a ladder platform arranged with the ladder and configured for placement atop the nacelle. Further, the ladder assembly includes a mounting assembly for affixing the ladder platform atop the nacelle. More specifically, the mounting assembly is adjustable between multiple positions so as to level the ladder platform atop the nacelle. Thus, the ladder assembly provides access to one or more uptower, external features of the wind turbine.
