Abstract
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.
Claims37
A hoisting system for installation or maintenance of a wind turbine, said hoisting system comprising:
- a column, a boom and a winch, the winch being configured to achieve a load bearing connection to an installed part of a tower of the wind turbine using one or more fixation points, wherein the one or more fixation points are successively located along a longitudinal direction of the tower, and wherein the column is arranged to move the hoisting system essentially in a vertical direction along said part of the tower when the load bearing connection is created;
- and
- an actuator configured to move the hoisting system up and down along previously installed parts of the tower, and wherein the hoisting system 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,
- wherein the load bearing connection between the column and the one or more fixation points is such that during a hoisting operation the load bearing connection allows for at least 0.25 degrees rotational freedom about an imaginary horizontal axis between parts joined by the load bearing connection.
