The collector rests on a ball joint by means of which it is connected to the ground, said ball joint being surrounded by a series of hydraulic arms arranged in two imaginary concentric rings. The aforementioned arms are hinged at the ends thereof to the collector and the corresponding foundation. In addition, the structure is stabilized by at least four towers (12) connected in pairs by a cable (13) that follows a closed path and is rigidly secured to the structure (2) at two diametrically opposed points of attachment (14), in such a way that the collector is pulled in one direction or another by means of multiple pulleys associated with the lower and upper ends of each of the two opposing towers, said cable passing through a braking means (17). |
