Abstract
The present disclosure is directed to a system and method for removing or installing a main shaft of a drivetrain assembly of a wind turbine to and from a nacelle installed atop a wind turbine tower. The rail system includes at least one support component configured to support the main shaft. Further, the support component is configured horizontally with respect to the main shaft. The rail system also includes at least one sliding component connected between the support component and the main shaft. Thus, the sliding component is configured to move horizontally with respect to the support component so as to slide the main shaft between an installed position and an uninstalled position.
