A steel tower ring segment for a wind turbine tower section, to a wind turbine tower section, to a wind turbine tower and to a wind turbine, and also to methods for producing a steel tower ring segment and a wind turbine tower section. A steel tower ring segment for a wind turbine tower section, comprising a first casing segment with a segment height, a segment length in the segment circumferential direction, a first segment thickness, and a first horizontal joint side, wherein the first casing segment has a first thickening region in a region adjoining the first horizontal joint side, wherein the first thickening region has a first thickening thickness, and the first thickening thickness is larger than the first segment thickness, wherein the first thickening region has a first cutout, wherein the first cutout is arranged spaced apart from the first horizontal joint side, and wherein a first passage opening leads from the first cutout to the first horizontal joint side.

Annular steel-tower segment for a wind turbine tower portion, and method

A method for transporting a tower section of a wind turbine, comprising the steps of: providing a tower section which is adapted to be transported in a predetermined transport position, wherein the tower section when in the transport position has a longitudinal axis extending in the horizontal direction and a wall extending along the longitudinal axis, wherein the tower section is adapted to adopt a first vertical height when in an unstressed state in the transport position, applying a deformation force to the wall so as to elastically deform at least one portion of the tower section in such a way that the tower section adopts a second vertical height that is smaller than the first vertical height when in an elastically deformed state in the transport position, and locking the tower section in the elastically deformed state.

Method for transporting a tower section, tower section, transportation system and method for installing a wind turbine

A semi-finished part for a foundation of a tower construction, in particular of a wind turbine tower, comprising at least two semi-finished part foundation segments, which each have an outer delimitation element and a reinforcement, which is connected to the outer delimitation element and comprises struts protruding from the outer delimitation element, wherein: the outer delimitation elements of the semi-finished part foundation segments form an outer edge, which delimits an interior to be later filled curable casting material; and the reinforcements of the semi-finished part foundation segments extend from the outer edge into the interior.

Semi-finished part for a foundation of a tower construction, semi-finished part foundation segment, foundation, method for producing a semi-finished part and method for producing a foundation

There is provided a wind power installation pylon comprising a plurality of pylon segments which respectively have an upper and a lower horizontal flange. At least one of the plurality of the pylon segments has at least two longitudinal flanges. Each longitudinal flange has a first side for bearing against a first side of a further longitudinal flange and a second side to which the peripheral surface is welded, wherein the second side is opposite to the first side.
