Abstract: A transport frame (100, 102) for a nacelle (14) includes a pair of lower nacelle mounts (128, 130) and a pair of upper nacelle mounts (204, 206). Each of the lower nacelle mounts (128, 130) includes a plurality attachment points for attaching to the nacelle (14) at a plurality of different widths. Each of the upper nacelle mounts (204, 206) includes a plurality of attachment points for attaching to the nacelle (14) at a plurality of different widths. The pair of lower nacelle mounts (128, 130) and the pair of upper nacelle mounts (204, 206) are adjustably positioned to allow the transport frame (100, 102) to attach to the nacelle (14) at a plurality of different heights. The ability of the transport frame (100, 102) to attach to the nacelle (14) at a plurality of different widths and heights allows the transport frame (100, 102) to be used on nacelles (14) having different sizes. Methods of using the transport frames (100, 102) are also disclosed.

Abstract: A tool chain (10) is provided for performing a method of removing internal components such as a bearing cassette (64) from the interior of a generator (12) and/or a gearbox (14) of a wind turbine. The tool chain (10) includes a tube (30) that extends through the interior of the generator (12), at least one clamp element (36) that concentrically fixes the tool chain (10) in position on at least one output shaft (60, 62) of the gearbox (14), and a sliding tool (50) that moves along the tube (30) into and out of the generator to couple with and pull out internal components to be repaired or replaced. For example, the tool chain (10) can remove the bearing cassette (64) located adjacent the junction of the gearbox (14) and the generator (12) without necessitating disassembly of the gearbox (14) from the generator (12).

Abstract: A blade access system (24) includes a support frame (28) configured to be coupled to a nacelle (14) of a wind turbine (10), the support frame (28) having at least one connecting member (42) configured to be selectively attached to and detached from at least one connecting member (40) included with the nacelle (14). A nacelle (14) includes at least one connecting member (40) configured to be coupled to at least one connecting member (42) of a support frame (28) of a blade access system (24). The at least one support frame connecting member (42) is configured to cooperate with the at least one nacelle connecting member (40) to define an unlocked position which is configured to allow the support frame (28) to attach to and detach from the nacelle (14), and a locked position which is configured to prevent the support frame (28) from detaching from the nacelle (28). A method of connecting the blade access system (24) to the nacelle (14) is also disclosed.
