The present invention relates to an assembly stand and an assembly method for assembling a gear unit and a main shaft unit of a wind turbine. The assembly stand comprises a main shaft frame unit and a gear frame unit arranged on a base frame, wherein both frame units comprises adjustment means for adjusting the position of the main shaft unit and the gear unit in at least a horizontal or vertical direction. The main shaft unit and the gear unit are aligned by using a light source emitting a light beam onto removable guiding elements. The main shaft unit is positioned on a slidable seat and pulled into contact with the gear unit by pulling elements located on a moveable unit. The pulling element is connected to the gear unit via a wire extending through the main shaft unit. |
