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.
