In one aspect the invention is an apparatus with a frame, flexible hoisting means for holding the blade, a drum to which each flexible hoisting means is attached, a stabilizing means for stabilizing the apparatus, and a drive means for rotating the drums. In another aspect, the invention is a method for lifting a blade to a support, which involves inserting flexible hoisting means through different apertures of a support and the corresponding apertures in the blade, and providing means to controllably reduce the length of the flexible hoisting means while holding the blade.
