Abstract
A lifting device for a wind turbine component includes a yoke for connecting the wind turbine component to a crane, the yoke including at least one sensor for measuring the position and/or the speed and/or the acceleration of the wind turbine component at least during a lifting operation of the component is provided. The yoke further includes a pitching device for rotating the wind turbine component around a pitching axis when the wind turbine component is connected to the yoke. The lifting device further includes a controller for controlling the rotation of the pitching device around the pitching axis as a function of the measurement of the at least one sensor.
Claims9
A lifting device for a wind turbine component comprising a yoke for connecting the wind turbine component to a crane, the yoke including at least one sensor for measuring at least one of the position, the speed and the acceleration of the wind turbine component at least during a lifting operation of the component,
- wherein the yoke further includes a pitching device for rotating the wind turbine component around a pitching axis when the wind turbine component is connected to the yoke,
- wherein the lifting device further includes a controller for controlling the rotation of the pitching device around the pitching axis as a function of the measurement of the at least one sensor.
A method for lifting a wind turbine component comprising the steps of:
- lifting the component,
- measuring the position and/or the speed and/or the acceleration of the component during the lifting step,
- rotating the wind turbine component around a pitching axis depending on the position and/or the speed and/or the acceleration detected in the step of measuring.
