An adaptor (166) for interfacing between an endpiece (38) of a lifting apparatus (30) and a nacelle (14) of a wind turbine (10). The adaptor (166) includes a base plate (174) having projections (204) configured to engage the adaptor (166) to the nacelle (14) and first and second side legs (176, 178) extending away from the base plate (174) opposite the projections (204) that define a recess (202) configured to engage the adaptor (166) with the endpiece (38) of the lifting apparatus (30). The adaptor (166) further includes first and second set screws (208, 210) positionable in bores (212) of the first and second side legs (176, 178) and movable to laterally adjust the position the adaptor (166) relative to the endpiece (38) of the lifting apparatus (30). This allows the lifting apparatus (30) to lift a nacelle assembly (24) having a laterally offset centre of gravity (158) in a balanced manner. A method for handling multiple wind turbine (10) components, including a nacelle (14), through selective use of the adaptor (166) is also disclosed.

The invention relates to a wind turbine nacelle (2) configured for mounting on a wind turbine tower (3) and housing a rotor-supporting assembly supporting a rotor, the nacelle further housing a power conversion assembly, the nacelle comprising: a main unit (20, 101) arranged to be connected to the wind turbine tower (3) and housing the rotor-supporting assembly, and at least one auxiliary unit (21, 22, 102) housing an operative component (34, 35, 104) forming part of the power conversion assembly, wherein the main unit (20, 101) and the auxiliary unit (21, 22, 102) are separate units configured to be connected by a unit fixation structure at an interface, and wherein the at least one auxiliary unit has a first height in an assembled configuration and a second height in a transportation configuration, the first height being higher than the second height.

The present invention relates to a system for handling a nacelle of a wind turbine for instance for the purpose of transporting the nacelle to or from a site of installation of the wind turbine, wherein the system reduces the loading and/or unloading time and provides a more flexible planning for the nacelle transportation, and the invention also relates to a method for loading a nacelle of a wind turbine on a transportation means and a method for unloading a nacelle of a wind turbine from a transportation means.

The invention relates to a wind turbine nacelle (2, 40) configured for mounting on a wind turbine tower (3), the nacelle comprising a top cover comprising multiple cover elements (41, 42, 43, 44), of which at least one is a dome cover element (44) comprising a dome-shaped part (45); wherein said nacelle has a second configuration in which said dome-shaped part (45) protrudes upwards and a first configuration in which said dome-shaped part (45) protrudes downwards.

A modular jib crane for a nacelle for a wind turbine includes: a base element for attaching the crane to the nacelle, a pillar, wherein the pillar is coupleable with the base element at a first end of the pillar, and a first crane arm, wherein the first crane arm is coupleable with the pillar at a first end of the first crane arm, wherein at least one of the pillar and the first crane arm includes a plurality of modules coupleable with each other to form the pillar or first crane arm.
