Abstract
A lift system and a method for constructing a wind turbine are disclosed. The lift system includes a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. The lift system further includes a lift device including a sling and a quick release device. The sling is coupled to the rotor blade and includes a first end and a second end spaced apart by an intermediate portion. The second end is releasably joined to the first end by the quick release device. The quick release device is operable to release the second end from the first end to uncouple the sling from the rotor blade.
