Abstract: An airfoil rack arrangement for supporting the airfoils of a plurality of rotor blades is provided, including a number of upright support structures; and a number of airfoil carrier brackets, wherein an airfoil carrier bracket is constructed to extend outward from a support structure. The airfoil rack arrangement includes an airfoil carrier bracket is rotatably mounted to a support structure and configured to rotate between a loading position in which the airfoil carrier bracket is positioned to support the airfoil of a rotor blade, and an unloading position in which the airfoil carrier bracket is out of the path of a rotor blade being lifted vertically.

Abstract: A wind turbine blade handling tool includes at least one supporting segment for supporting a surface portion of an outer surface of the blade during handling of the wind turbine blade, wherein the supporting segment includes at least one deformable protection pad, which is deformable in such manner that at least one blade add-on element protruding from the supported surface portion is completely accommodated in the deformed protection pad.

Abstract: A wind turbine blade includes a plurality of add-on elements, which are arranged on an outer surface of the blade, wherein the plurality of add-on elements includes at least one flexible add-on element and at least one stiff add-on element of the same add-on element type, wherein the flexible add-on element is made at least predominantly of an elastic material and the stiff add-on element are made at least predominantly of a stiff material, which is stiffer than the elastic material, wherein the flexible add-on element and the stiff add-on element are arranged offset in span-wise direction and/or in chord-wise direction of the blade.

Abstract: A mounting bracket device and method for mounting a blade of a wind turbine to a transportation device are disclosed. The mounting bracket device includes a clamping device for holding the blade, an adjustment system, and a connecting system adapted for being removably connected to the transportation device. The connecting system removably connects the clamping device and the adjustment system to the transportation device. The adjustment system is adapted to align the clamping device with respect to the transportation device around the first rotary axis and around a second rotary axis.

Abstract: At least one blade of the wind-turbine is attached firm but detachable with the tower by a fixture. The tower and the attached blade are transported to a planned site. The tower and the attached blade are brought together into an upright position in a single lift-action. A hub and a nacelle of the wind-turbine are mounted on the top of the tower. A wire of a winch, which is located inside the nacelle or the hub, is connected with a root of the blade. The blade is detached from the tower by unlocking the fixture. The blade is lift up to the hub for its attachment there.

Abstract: A fixation system for fixing wind turbine elements of a wind turbine to a vehicle is provided. The fixation system includes a first fixation device for fixing a first portion of a wind turbine element pivotably around a first axis of the first fixation device and around a second axis of the first fixation device to the vehicle. A second fixation device fixes a second portion of the wind turbine element pivotably around a first axis of the second fixation device and around a second axis of the second fixation device. One of the first fixation device and of the second fixation device is adapted for providing a translation movement of the wind turbine element with respect to the vehicle along a third axis. The first axis, the second axis and the third axis are different.
