Abstract
A method for removing and replacing an article of wind turbine equipment, such as a yaw drive, internal to a nacelle of a wind turbine tower without use of an external windfarm site crane or external rigging on the wind tower. External rigging of wind turbine tower components may expose workers and the equipment inside the nacelle to outside weather and hazardous wind conditions. The yaw drive is internally rigged with an internal support crane within the nacelle to an internal winch capable of supporting the yaw drive during a lift to the base of the wind turbine tower.
