The invention relates to a rotating tower crane (1) for erecting a wind turbine, having a tower (3) and a tower substructure (5), which is connected to the tower (3) and is intended for supporting the tower, wherein the tower substructure (5) has a supporting cross frame, which has three or more, preferably four, legs (7), extending from the tower (3). According to the invention, it is proposed that each leg has fastened on it, on the ground side, a load-distributor plate (11a, b), which is not connected to the foundation (101), wherein the load-distributor plates (11a, b) together form the ballast of the tower.

    L'invention concerne une grue à tour (1) destinée à construire une éolienne. La grue à tour comprend une tour (3) et une sous-structure de tour (5) reliée à la tour (3) pour la soutenir. La sous-structure de tour (5) comporte une croix d'appui, qui comporte trois pieds (7) ou plus, de préférence quatre, qui s'étendent à partir de la tour (3). Une plaque de répartition de charge (11a,b) non reliée à la base (101) est fixée à chaque pied côté sol et les plaques de répartition de charge (11a,b) forment ensemble le lest de la tour.
