摘要： 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.

摘要： A rolling ladder includes opposing side members between which a plurality of treads are disposed at predetermined locations to define a ladder. The ladder further includes a support structure coupled to the ladder and including a front wheel support coupled to a plurality of rolling devices. A leg assembly has a user-adjustable length leg, and is coupled to the support structure. A lock mechanism is responsive to user actuation and is configured to move the rolling devices from a rolling position to a retracted position, wherein the leg of the leg assembly contacts the floor to thereby inhibit movement of the ladder.

摘要： A lift adapted to be attached to a rolling ladder having a frame including first and second spaced-apart frame members mounted on wheels and between which are attached a series of inclined ladder steps. The lift includes a base on which is mounted a lift motor, a vertically-extending mast positioned on and extending upwardly from the base, and a load-carrying lift platform mounted on the mast and adapted for motor-powered movement of the lift platform and load up and down the mast. At least one laterally-extending attachment member is carried by the mast and adapted to be attached to the first and second spaced-apart frame members for attaching the lift to the rolling ladder. The attachment member is width-adjustable to permit the lift to be attached to rolling ladders of different widths.
