Abstract

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.

         5 . The arrangement according to  claim 1 ,
 wherein the first end frame and the first centre frame are coupleable to the supporting base such that a direction of a first chord line of a first profile of the first centre section of the first blade is alignable parallel to an upper surface of the supporting base.   
     
     
         6 . The arrangement according to  claim 1 ,
 wherein the first end frame and the first centre frame are coupleable to the supporting base such that the direction of the first chord line of the first profile of the first centre section of the first blade is alignable perpendicular with respect to an upper surface of the supporting base.   
     
     
         7 . The arrangement according to  claim 1 ,
 wherein the first centre frame comprises a carrying element, and   wherein the carrying element is formed such that the first centre frame is coupleable to the supporting base.   
     
     
         8 . The arrangement according to  claim 1 , further comprising
 a second end frame for holding a second root end of a second blade, wherein the second end frame is formed for being coupled to the supporting base, and   a second centre frame for holding a second centre section of the second blade in such a way that the second centre section is spaced from a second tip end of the second blade, and   wherein the second centre frame is formed for being coupled to the supporting base.   
     
     
         9 . The arrangement according to  claim 8 , wherein the second centre frame is coupled to the first centre frame such that the second centre frame is coupled to the supporting base by the first centre frame. 
     
     
         10 . The arrangement according to  claim 8 ,
 wherein the second end frame and the second centre frame are coupleable to the supporting base such that a second direction of a second chord line of a second profile of the second centre section of the second blade is alignable parallel to an upper surface of the supporting base.   
     
     
         11 . The arrangement according to  claim 8 ,
 wherein the second end frame and the second centre frame are coupleable to the second supporting base such that the second direction of the second chord line of the second profile of the second centre section of the second blade is alignable perpendicular to an upper surface of the supporting base.   
     
     
         12 . The arrangement according to  claim 8 ,
 wherein the first end frame is further formed such that the second tip end of the second blade is coupleable to the first end frame, and   wherein the second end frame is further formed such that the first tip end of the first blade is coupleable to the second end frame.   
     
     
         13 . A transporting system for transporting blades for a wind turbine, the transporting system comprising:
 an arrangement for holding blades according to  claim 1 ,   a transporting device comprising the supporting base, and   wherein the arrangement is detachably coupled to the supporting base.   
     
     
         14 . A method of holding blades for a wind turbine, the method comprising
 coupling a first root end of a first blade to a first end frame for holding the first root end, wherein the first end frame is formed for being coupled to a supporting base, and   coupling a first centre section of the first blade to a first centre frame for holding the first centre section in such a way that the first centre section is spaced from a first tip end of the first blade, wherein the first centre frame is formed for being coupled to the supporting base.
