It emphasizes the simplicity of the structure and the arrangement of the associated systems. The simple assembly and disassembly of the assembly for its later transfer to the next wind turbine. The three masts are braced together from the top in such a way that they stiffen the whole.
- the lifting triangle which goes up and down in contact with the walls of the masts, is made up of different pieces assembled together, which incorporate guide elements to control their connection with the masts and adjustment elements. to facilitate the horizontal movement of the lattice module once it has been assembled and its corresponding subsequent puncture on the foundation.
- Another object of the invention is that the automated system has new features both for anchoring with the module columns, and for lifting the columns of the lower module while the upper module is being lifted, thus constituting a new method of assembling the lattice modules that make up the lower part of the tower.
- the automated system is totally modular, transportable and electric. It is designed to operate in high wind conditions (18m/s gust and 12m/s average) reducing assembly downtime and resulting downtime savings.
- Figure 1 shows the upper part of the wind turbine and the automated system, assembled and ready to complete the assembly of the lattice part.
- Figure 2a shows the arrangement of the support bases with respect to the transition piece and figure 2b shows a detail of said base.
- Figure 3a shows the arrangement of the lifting triangle added to the previous figure and figure 3b a detail thereof.
- Figure 4a is a detail of the corner of the triangle and figure 4b the same detail with the mast attached.
- Figure 5 shows the layout of the masts on the bases and the hoisting triangle, completing the self-hoisting system.

Two upper beams (10) support and anchor the feet of the masts and the winch (not shown in the figure) and are joined to the foundation (6) by multiple tie rods (11).
- the lifting triangle (12) is arranged bordering the transition (4) and its function is to raise the wind turbine supporting the vertical loads that are generated, reacting these loads through the lifting system (5).
- Figure 3b details the main elements of the lifting triangle (12): the sides and the vertex.
- the side elements are horizontal pieces (13), with a beam structure, which provide maximum rigidity with minimum weight.
- the horizontal piece (13) can be a single piece or be made by joining several pieces.
- the vertex includes a retractable bolt (14) that first goes through the columns at the bottom of the transition (4) and then the columns of the modules to be inserted to complete the tower.
- the vertex also includes the guiding elements (15) that fix the position of the triangle (12) with respect to the masts (17), in addition to transmitting to said masts (17) the horizontal forces of the wind when it hits the wind turbine.
- the vertex includes the mobile pulley holder (16) that raises and lowers the triangle (12). And it also includes the interface beam (19) that serves as a support for the cables that support the retractable bolt (14), which in the present figure crosses the lower ends of the columns of the transition piece (4).
- Figure 4a details the vertex of the lifting triangle (12) when the mast is not shown and in figure 4b when it is shown attached to the mast (17).
