A method of assembling a rotor lock assembly for use in a wind turbine. The wind turbine includes a rotor rotatably coupled to a generator by the rotor shaft. The generator and the rotor shaft are supported from a bedplate frame. The rotor shaft includes a rotor lock disk. The method includes coupling a support frame to the bedplate frame. The support frame is positioned adjacent to the rotor lock disk. A plurality of lock pin housings are coupled to the support frame. Each lock pin housing of the plurality of lock pin housings is positioned with respect to the rotor lock disk. A plurality of lock pins is provided. Each lock pin of the plurality of lock pins is configured to engage the rotor lock disk. Each lock pin is coupled between a corresponding lock pin housing of the plurality of lock pin housings and the rotor lock disk to facilitate limiting a rotation of the rotor shaft.

Systems and methods for assembling a rotor lock assembly for use in a wind turbine

A method of assembling a gearbox handling assembly to facilitate removal of a gearbox from a wind turbine uptower from the wind turbine. The wind turbine includes a rotor rotatably coupled to the gearbox with a rotor shaft. The gearbox and the rotor shaft are supported from a support frame. The method includes coupling a support assembly between the gearbox and the support frame for supporting the gearbox from the support frame. A positioning assembly is coupled to the support frame. The positioning assembly is configured to contact the gearbox to move the gearbox between a first position wherein the gearbox is operatively coupled to the rotor shaft and a second position wherein the gearbox is operatively decoupled and spaced from the rotor shaft to facilitate removing the gearbox from the wind turbine without removing the rotor from the wind turbine.
