It includes at least one platform (10) defining a plane, first and second sets of complementary coupling elements (20, 30) associated with the tower section (100) and the platform (10), respectively, and arranged in levels. In a first relative position of the sets of coupling elements (20, 30), the platform (10) is allowed to pass, in a substantially horizontal position, through different levels of sets of coupling elements (20, 30); and in a second relative position of the sets of coupling elements (20, 30), the platform (10) rests with its second set of coupling elements (30) on a first set of coupling elements (20) of one given level. Means for moving the platform (10) may be provided for fitting it inside the tower section (100). The first or the second set of coupling elements (20, 30) in different levels are aligned along a longitudinal direction inside the tower section (100). |
