Patent ID: 8500400

Claim:
A component handling system for use in a wind turbine, the wind turbine including a rotor, a drive train assembly supported from a support frame, and a drive shaft rotatably coupled between the rotor and the drive train assembly, said component handling system comprising: a lifting assembly removably coupled to a component of the drive train and a lifting device, said lifting assembly configured to support the component from the lifting device, said lifting assembly comprising: a plurality of lifting legs extending between the component and the lifting device, each lifting leg of said plurality of lifting legs having a first end, an opposite second end, and a length defined therebetween; an alignment device coupled to at least one said lifting leg of said plurality of lifting legs, said alignment device configured to adjust a length of said at least one lifting leg to adjust an orientation of the component with respect to the drive shaft; and, a positioning assembly coupled to the component and to the support frame, said positioning assembly comprising: at least one adjustable aft positioning member coupled to a component aft portion, said at least one adjustable aft positioning member configured to bias the component away from the drive shaft; and, at least one adjustable forward positioning member coupled to a component forward portion, said at least one adjustable forward positioning member configured to bias the component towards the drive shaft.
