Abstract: A method of handling an auxiliary nacelle unit (24, 26) of a wind turbine (10) includes assembling a temporary hoist (52) on a main nacelle unit (22) by pivotally connecting a boom (64) to the main nacelle unit (22), pivotally connecting a mast (66) to the main nacelle unit (22), connecting the actuator (68) between the mast (66) and the boom (64), and routing a hoist cable (56) from a winch (54) to a hoist cable locator (60). The method further includes connecting the hoist cable (56) to an auxiliary nacelle unit (24, 26), activating the winch (54) to move the auxiliary nacelle unit (24, 26) from a first position to a second position, and activating the actuator (68) to move the boom (64) between the retracted position and the extend position. A lifting arrangement (50) for handling an auxiliary nacelle unit (24, 26) of a wind turbine (10) is also disclosed.
