    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.

    Abstract: The invention provides a method for installing or removing components (314, 322) of a wind turbine (3), comprising separately fastening two or more wind turbine components (314, 322) to a respective receiving structure (319, 323) of the wind turbine, or separately releasing the components (314, 322) from the respective receiving structure (319, 323), characterised by, before the fastening of the components (314, 322), or subsequently to the releasing of the components, lifting the components (314, 322) simultaneously, so as to be carried by a lifting line (441) of a crane (1), wherein the directional inter-relationship of the components, during the lifting of the components (314, 322), is substantially the same as the directional inter-relationship of the components when fastened to the respective receiving structure (319, 323).

    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 (12) 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).
