Method for installing a tower and tower installed by said method

A method for installing a tower formed by the stacking of two or more mounting groups on a base section, one of said mounting groups representing a top mounting group of the tower, wherein at least one of said mounting groups is formed by a plurality of stacked segments, comprising, at least, a lowest stacked segment and a highest stacked segment;

• wherein said method comprises at least the following steps performed in any order that is technically possible:
• a) arranging or constructing the base section in a definitive position thereof on a foundation;
• b) arranging at least one mounting crane for lifting and placing the mounting groups of the tower on the base section, said crane being able to adopt a plurality of jib configurations and said configurations being differentiated by at least the height of the crane jib and/or the loading threshold value of the crane;
• c) lifting and successively arranging the stacked segments in the corresponding mounting groups on the base section by means of said mounting crane, using a different jib configuration for each mounting group;
• wherein, in step c), the stacked segments are arranged so that, in at least one mounting group, the length of the lowest stacked segment of said mounting group is smaller than the length of at least another stacked segment of said mounting group, thereby minimizing the number of different jib configurations used for a given total height of the tower.
