    Abstract: This application relates to tower segment handling methods and apparatus and, in particular, to methods and apparatus for handling segments of steel wind turbine towers. The wind turbine tower comprises a plurality of cylindrical vertical tower sections, which in the finished tower are mounted on top of one another. The vertical section of the tower has a longitudinal axis and comprises a plurality of wind turbine tower segments, the tower segments have vertical and horizontal edges and combine to form a complete vertical tower section by joining along their vertical edges. Adjacent vertical tower sections are joined to each other along the horizontal edges of the wind turbine tower segments. The tower segments are combined into a tower section using a flat roller bed on which the segments can be assembled. A method of assembling a tower section is discussed.

    Abstract: A wind turbine tower configured to support a wind turbine nacelle and a rotor, and with a tower wall of an inner surface and an outer surface. The tower is tethered by a number of cables, each cable extending between a first end anchored to an anchoring element and an opposite, second end attached to the tower at an attachment element. Two cables extending from two different anchoring elements are attached to the tower such that longitudinal projection lines from the second ends of the two cables converge at a convergence point, which lies at a location at a certain height and inside the tower wall thickness. Alternatively, the convergence point lies inside the tower within a distance of three wall thicknesses from the wall inner surface as measured at the height and in a direction perpendicular to the central longitudinal axis of the tower. The invention further relates to a method of erecting a wind turbine tower tethered by cables and configured for supporting a rotor assembly, and wherein the tower comprises a number of tower sections joined to each other. The method comprises positioning a first tower section, attaching at least some of the tethering cables to a second tower section while the second tower section is on the ground, lifting the second tower section with the attached cables onto the first tower section, and joining the second tower section to the first.

    Abstract: A lifting arrangement (1) for lifting a wind turbine tower segment (2), the lifting arrangement (1) comprising at least two component pulley arrangements (3) connected to a flange (5) of the tower segment, and at least one hoisting pulley arrangement (4), arranged to be connected to a hoisting apparatus. A rope (8) interconnects the component pulley arrangements (3) and the hoisting pulley arrangements (4), in such a manner that each component pulley arrangement (3) is connected to two hoisting pulley arrangements (4), or to one hoisting pulley arrangement (4) and a rope end attachment point (9), via the rope (8), and each hoisting pulley arrangement (4) is connected to two component pulley arrangements (3), via the rope (8), the rope (8) being arranged movably in each pulley arrangement (3, 4). The tower segment (2) is automatically rotated from a first orientation into a second orientation during the lifting process. Load distribution among various parts of the rope (8) is ensured.

    Abstract: The invention relates to a method of erecting a tower such as a wind turbine tower tethered by a number of cables where each of the cables extend between the tower and an anchoring element on an anchor block. The method comprises attaching at least some of the tethering cables to the tower, detachably fastening a motorized winch on an anchor block and connecting the wire of the winch to the end of a tethering cable. The winch is then operated to wind up the wire of the winch pulling the cable end towards the anchor block and into position for fastening the cable end to the anchoring element, where the cable end is then fastened to the anchoring element while held in position by the winch. The invention further relates to the use of a motorized winch to connect a cable to an anchor block when erecting a tower tethered by a number of cables as mentioned above.
