The blade hoisting element is an intermediate piece (3) placed between the root of the blade (1) and the mobile track of the blade bearing (16). This piece comprises at least an insert (9') or (9") and joins, by means of a rigid rod (21) or strut (13) with another intermediate piece (3) opposing diametrically. The piece has a hole (5) for connecting to the hoisting point and another hole (4) for connecting to the hub, this latter fastening to the hole (2) of the insert by a long bolt (17) or (17'). Two hoisting points are established on the blade, namely at its root and at the tip: the hoisting point at the root is handled from a single lift point on the hub and the hoisting point at the blade tip is handled from two lift points: one from the hub and the other from the ground. The hoisting method starts with the blade placed horizontally to be subsequently moved to a vertical position.
