Abstract: The present invention relates to an assembly for rotating a suspended load around a substantially vertical axis, the assembly comprising an inner rim configured to have a fixed relationship with the suspended load to be rotated, an outer rim engaging the inner rim in a manner so that the inner and outer rims are configured to perform rotational movements relative to each other during rotation of the suspended load, and a drive unit for performing the relative rotational movement between the inner and outer rims. The assembly of the present invention may be secured to a lifting yoke for lifting wind turbine related components, such as entire wind turbine towers, wind turbine tower sections, nacelles, rotor blades or containers.

Abstract: A method for handling wind turbine sub-assemblies includes coupling a connecting device to a connector of a hoisting device at a first connection interface of the connecting device; coupling a first wind turbine sub-assembly to the connecting device at a second connection interface of the connecting device; moving the first wind turbine sub-assembly with the hoisting device; coupling a second wind turbine sub-assembly different than the first wind turbine sub-assembly to the connection device at a third connection interface of the connecting device; and moving the second wind turbine sub-assembly with the hoisting device. An apparatus for handling wind turbine sub-assemblies is also disclosed.

Abstract: A method for handling wind turbine sub-assemblies (14, 16) includes coupling a connecting device (44) to a connector (46) of a hoisting device at a first connection interface of the connecting device; coupling a first wind turbine sub-assembly to the connecting device at a second connection interface (60) of the connecting device; moving the first wind turbine sub-assembly with the hoisting device; coupling a second wind turbine sub-assembly different than the first wind turbine sub-assembly to the connection device at a third connection interface (76) of the connecting device; and moving the second wind turbine sub-assembly with the hoisting device. An apparatus (26) for handling wind turbine sub-assemblies is also disclosed.
