A component handling system (112) for use in a wind turbine (10) is described herein. The wind turbine includes a rotor (22), a drive train assembly (20) supported from a support frame (16), and a drive shaft (24) that is rotatably coupled between the rotor and the drive train assembly. The component handling system includes a lifting assembly (130) that is removably coupled to a component (114) of the drive train and a lifting device (116). The lifting assembly is configured to support the component from the lifting device, and includes a plurality of lifting legs (140) extending between the component and the lifting device. Each lifting leg of the plurality of lifting legs includes a first end, an opposite second end, and a length defined therebetween. An alignment device (160) is coupled to at least one lifting leg of the plurality of lifting legs, and is configured to adjust a length of the at least one lifting leg to adjust an orientation of the component with respect to the drive shaft.
