Wind turbine blades lifting device comprising a structure (1) for supporting the blade (3) during lifting. The structure (1) is made of a rigid material and defines a hollow closed contour with a geometry suitable for surrounding the blade (3), the device (100) further comprising a pneumatic chamber (4) attached to the structure (1) and arranged in the hollow area of the closed contour defined by said structure (1) such that the pneumatic chamber (4) surrounds the blade (3) at least partially. The pneumatic chamber (4) is inflatable and is arranged in the closed contour defined by the structure (1), such that when it is inflated, said pneumatic chamber (4) retains the blade (3), immobilizing it and preventing direct contact between the structure (1) and the blade (3).
