20130319891 | TRANSPORTATION AND STACKING OF CURVED BLADES LYING OPPOSITELY AND ABOVE EACH OTHER - An arrangement is provided for holding blades for a wind turbine. The arrangement includes a first end frame and a first centre frame. The first end frame is configured for holding a first root end of a first blade. The first end frame is formed for being coupled to a supporting base. The first centre frame is configured for holding a first centre section of the first blade in such a way that the first centre section is spaced from a first tip end of the first blade. The first centre frame is formed for being coupled to the supporting base. | 12-05-2013 |
20140314576 | WIND TURBINE BLADE HOLDING ARRANGEMENT - A wind turbine blade holding arrangement is described comprising a root frame for securing to a root portion of a blade; an airfoil clamp for arranging about an airfoil portion of the blade; and an airfoil frame for supporting the airfoil clamp wherein the root frame and tip clamp are realized for use in a first blade orientation in a first storage and transport stage of the blade and also for use in a second blade orientation in a second storage and transport stage of the blade, wherein the first and second blade orientations are essentially at right angles to each other. A method of handling a number of wind turbine blades is also described. | 10-23-2014 |
20150016939 | RAISING A TOWER SEGMENT - A raising device realized to be connected to a tower segment of a wind turbine is provided. The raising device comprises a connection member to a raising machine and a plurality of holding members positioned at predefined distances from each other and orientated to be movable in radial locking directions which locking directions are such that the holding members when moved into a locking position at a predefined engagement position of the tower segment engage with a counter-shape of the tower segment, whereby the holding members are automatically tiltable and/or shiftable into the locking position by a movement mechanism. A method of equipping a tower segment of a wind turbine for transport by means of such raising device is also provided. | 01-15-2015 |
20150026978 | BLADE GRIPPING DEVICE WITH RECTANGULAR CARRYING STRUCTURE - A blade gripping device for gripping a rotor blade of a wind turbine is provided. The device comprises a first frame which is essentially horizontally aligned in a designated operating position and a second frame which is essentially horizontally aligned in the designated operating position and a blade gripping assembly with a number of blade gripping tools. Thereby, the first frame and the second frame are connected to each other via a swivel or other similar type connection, the connection realized to permit a yawing movement of the second frame relative to the first frame. The first frame comprises a rectangular carrying structure with at least four connectors for connection to a lifting device, which connectors are positioned essentially at the corners of the rectangular structure. Further, the invention concerns a method of operating a blade gripping device for gripping a rotor blade of a wind turbine. | 01-29-2015 |
20150028609 | BLADE GRIPPING TOOL AND DEVICE - A blade gripping tool of a blade gripping device for gripping a rotor blade, in particular a rotor blade of a wind turbine is provided. The tool comprises a sling and an automatic sling handover mechanism comprising a sling-conveying element and a sling-receiving element, whereby the sling-conveying element is realized to convey a connection means of the sling along a two-dimensional predefined path of travel around a part of the rotor blade towards the sling-receiving element to connect to a receptor of the sling-receiving element. The invention also concerns a method of gripping a rotor blade, in particular a rotor blade of a wind turbine by means of a number of blade gripping tools. | 01-29-2015 |
20150028610 | BLADE GRIPPING DEVICE - A blade gripping device for gripping a rotor blade, in particular a rotor blade of a wind turbine, comprising a blade gripping assembly with a number of blade gripping tools and a sensor arrangement realized to sense a specific feature of the rotor blade is provided. Thereby, the specific feature is such that it can be used to orientate the blade holding device relative to the rotor blade in a blade gripping manoeuvre. Further the invention concerns a method of moving a blade gripping device for gripping a rotor blade, in particular a rotor blade of a wind turbine, relative to the rotor blade. | 01-29-2015 |
20150082743 | TRANSPORT OF A TOWER OF A WIND TURBINE - The disclosed concerns a method of transporting a tower of a wind turbine in an upright position to an assembly site of the wind turbine, whereby the tower is equipped with a strake set comprising a number of strakes positioned to lead from a top of the tower in the upright position down towards a bottom of the tower, at least one of the strakes being realized as a detachable strake. The invention also concerns a strake set and transport assembly. | 03-26-2015 |
