Abstract:
This invention relates to a tower for a wind turbine, comprising one or more tubular tower sections, having an outer jacket wall and an inward directed flange in its lower and upper ends, and at least one platform arranged inside the tower for facilitating access for maintenance and repairs to the inner of the tower and to the nacelle. The tower also comprises a support structure including at least three elongated tensile load carrying members, which each is attached in its upper end to the upper flange of the tower section and in its lower end to the lower flange of the tower section and which supports one or more platforms that are suspended by the tensile load carrying members while at least one ladder is attached to the platforms. The at least one ladder is stabilized in the horizontal direction by transversal tensile load carrying members extending from the ladder to the tensile load carrying members that are vertically arranged between the upper and lower flanges. The invention also relates to a method for arranging a platform inside a tower.
Abstract:
A wind power plant includes a tower, the tower including at least one tower section provided with at least one flange and forming at least part of the wall of the tower. The power plant further includes an element provided with at least one flange and adapted to be installed adjacent the tower section. The tower section and the element have abutting flanges, the flanges being releasably interconnected by sets of bolts and nuts. At least one surface associated with each set of bolt and nut and facing away from the flanges is provided with a plurality of recesses for receiving projections of a tightening device. A method of joining a tower section and an adjacent element is also disclosed.
Abstract:
The invention relates to a wind turbine tower comprising a tower foundation, and at least two tower sections connected by numerous sets of connecting means positioned in close proximity of each other. The connecting means comprising at least one nut with at least one assembly opening for interacting with an assembly tool.The invention also relates to a method for assembling a wind turbine tower and a method for manufacturing a nut of connection means for fixating a wind turbine tower including at least two tower sections.
