Abstract: A wind turbine includes a nacelle, a generator housed with the nacelle, a rotor having a rotatable hub with at least one rotor blade mounted thereto, at least one shaft rotatably coupled to the hub for driving the generator, and a rotor lock arranged with the shaft(s) for locking the shaft(s) in a locked position. The wind turbine also includes a bolted-joint connection at an interface between the hub and the shaft(s). The bolted-joint connection includes a first plurality of fasteners extending through the hub, the shaft(s), and the rotor lock. As such, a load transfer path from the hub to the shaft(s) travels through each of the hub, the shaft(s), and the rotor lock so as to increase a load capacity of the interface.

Abstract: The present disclosure is directed to a working platform mounted within a nacelle of the wind turbine during a repair procedure. More specifically, the working platform may be mounted to a bedplate within the nacelle in an area where one or more drivetrain component(s) would normally be during operation of the wind turbine, but have been removed due to repair or replacement thereof.

Abstract: A disassembled wind turbine under repair includes a tower secured to a foundation and a nacelle mounted atop the tower. The nacelle includes a base wall, side walls, a front wall, a rear wall, and a top wall. The front wall includes an opening configured to receive a main shaft of the wind turbine; however, the main shaft and a rotor of the wind turbine have been removed from the nacelle during a repair procedure. As such, the disassembled wind turbine further includes an external platform assembly secured at the opening of the front wall of the nacelle during the repair procedure.

Abstract: The present disclosure is directed to a hoistable platform assembly used in uptower wind turbine repairs. The platform assembly includes at least one working platform having a working surface and a platform frame. The platform frame is configured for securement within a nacelle of the wind turbine. The platform assembly also includes a plurality of tooling containers secured to the working surface. Each of the tooling containers includes at least one tool secured therein that is required for the uptower wind turbine repairs. Further, the platform assembly includes a frame structure arranged above the plurality of tooling containers and secured to the working surface via one or more connecting members.
