Abstract: A wind turbine lifting arrangement includes a tower, a nacelle, a lifting platform and a lifting device attached to the lifting platform for lifting components to be installed in or deinstalled from the nacelle, the nacelle including a main frame attached to a top section of the tower, an attachment portion of the lifting platform being arranged underneath the nacelle and attached to the main frame. The lifting platform includes a lifting device portion provided adjacent to the attachment portion, the lifting device is attached to the lifting platform in the lifting device portion and the lifting device portion and the lifting device are arranged next to a longitudinal side of the nacelle which is one of two opposite longitudinal sides of the nacelle extending along a longitudinal axis of the nacelle and arranged between a top side and bottom side of the nacelle.

Abstract: This handling tool for blades (11) comprises two semi-covers (1) hinged (2) on the leading edge, with enclosures on the trailing edge and double internal wall. A part (10) of the double wall is shifted towards the inside of the existing gap, reducing its volume and, with its movement, trapping the blade (11) without damaging it. The external part of each semi-cover (1) has several shafts (6) incorporating a retaining system that permits blade rotation (11) securely and at a controlled speed. The cited rotation control mechanism (8) is fit onto several ends that are supplemented with several cables (4) that raise and lower the blade (11) as necessary.

Abstract: Maintenance platform with detachable elements to facilitate its placement at any point of the ladder inside a wind turbine tower. The platform comprises a horizontal surface (1) with side skirting (4) to prevent the fall of objects, tensionable elements (5) that support it, anchors (2), secured by pins (3) to any rung on the ladder and a railing (9) anchored to the platform and reinforced by intermediate bars (14) and a plate (15). The work surface on the platform suffices for a worker and the corresponding maintenance tools.
