    DESCRIPTION
    Turning device of precast concrete segments and turning procedure with said device
    Technical Field of the Invention
    The present invention corresponds to the technical field of the turning systems of prefabricated concrete segments, in the construction of prefabricated concrete towers, such as those that make up the new precast concrete wind towers.
    Background of the Invention
    At present, most wind turbines are supported by metal or concrete towers in situ or prefabricated. The typology of prefabricated concrete towers for wind turbine support is diverse in dimensions, shapes, heights, thicknesses, etc., but there is currently a proliferation of precast concrete towers made up of prefabricated concrete rings or cylindrical sections and prefabricated segments of concrete.
    The type of precast concrete towers or shafts formed by segments, has many advantages over other wind turbine support systems, that is, those that are supported by metal towers or by towers made with rings.
    This is due to the fact that with the towers made by means of segments, 20m high sections are achieved, reducing the number of sections that form the tower, and consequently, the number of horizontal joints of the tower. In addition, wind turbines can be raised to heights above 100m, reducing production and assembly costs.
    The disadvantage of precast concrete spindles or towers made up of segments is the need to use large cranes for handling said segments. Thus, two cranes are required for handling and assembly of the different segments; a main one of 500T and another secondary one for the turning of the segments of 100T. These cranes

    They have a very high cost, and involve a loss of time due to delays and breakdowns, as well as wind limitations.
    No document has been found in the state of the art in which this subject is addressed, which may be due to the fact that the manufacture and assembly of these new towers or shafts is novel and recent. Yes, some solution has been found consisting of the turning of large tonnage parts, such as mining equipment hoppers and rotor turners for wind turbines, but there are no solutions to this problem.
    Thus, by way of example of these documents found, reference patent ES2479892 can be mentioned.
    This document defines a team to repair truck hoppers on the ground, which positions the hopper facilitating the repair and maintenance of the elements and surfaces to be repaired and avoids the use of cranes, which comprises two dismantling mechanical type towers with driving elements. such a height that the hopper can be raised and turned, attachable mechanical fastening means, safety mechanisms and lifting mechanisms.
