A tower segment, in particular for a tower of a wind turbine, a wind turbine, and a method for manufacturing a tower segment is provided. A tower segment, in particular for a tower of a wind turbine, comprising a casing segment with an inner casing surface, an outer casing surface and a cutout for a door, wherein the inner casing surface has a first inner reinforcing portion and/or the outer casing surface has an outer reinforcing portion, wherein the inner reinforcing portion and/or the outer reinforcing portion adjoin the cutout, and the inner reinforcing portion has an inner reinforcing plate and/or the outer reinforcing portion has an outer reinforcing plate.

Tower segment and manufacturing method

A hoisting system for the at least one of an installation, a decommissioning and a maintenance of a wind turbine which comprises at least a foundation, a tower, a yawing part and a rotor of at least 80 m diameter with at least one blade, comprising a first hoisting device which comprises measures to establish a load carrying joint with an already built part of the wind turbine which is located above the foundation, wherein the hoisting system is characterized in that the ratio between the maximum hoist load of the hoisting device and the mass of the heaviest part is larger than 0.2 and smaller than 1 and in particular smaller than 0.8 and more in particular smaller than 0.7 and preferably smaller than 0.6, with the heaviest part being a heaviest part which is hoisted as one piece and which belongs to the yawing part of wind turbine.

Hoisting system for installing a wind turbine

A hoisting system for the installation of a wind turbine wherein said hoisting system comprises measures to achieve a load bearing connection to the tower of the wind turbine and comprises measures to move the hoisting system up and down along the tower wherein the hoisting system, when it is fixed to an already installed part of the wind turbine tower with said load bearing connection, is arranged to install or remove any of a tower segment, a nacelle, a generator, a hub, and a blade in one or more combined hoists or in a single hoist.

A wind turbine includes a tower (), a nacelle () being connected to the tower (), and a rotor () having a rotor hub () and a number of rotor blades () extending radially outwards from the rotor hub (). The nacelle () includes a hollow shaft () and the rotor hub () includes a support member () which is connected to the hollow shaft () by two tapered roller bearings () so as to be rotatable about an axis of rotation (). The tapered roller bearings () each have a bearing width (w) which is defined in a direction parallel to the axis of rotation (). The tapered roller bearings () are arranged at a distance (d) from one another which is not greater than the bearing width (w) of the tapered roller bearings ().
