Abstract
A lifting fitting for lifting a series of elements of different sizes in a wind turbine is proposed. The lifting fitting has a base plate having at least one central slotted hole shaped to accommodate a fastener for fastening the lifting fitting to an element to be lifted, at least two outer slotted holes each shaped to accommodate a further fastener for fastening the lifting fitting to an element to be lifted. The outer slotted holes are arranged transverse to the central slotted hole. The lifting fitting is connected to a lifting apparatus for lifting the element. A method of assembling the series of elements is proposed. The elements are successively lifted into place. The lifting fitting can be used in the assembly of a wind turbine tower having individually liftable tower sections for lifting the tower sections into place.
