摘要： Lifting yoke and method; the lifting yoke configured for connecting to, and lifting, a wind turbine blade transport frame, said yoke being generally rectangular and comprising four corner posts connected by struts; each corner post being configured for internally receiving therein an upwardly oriented locating fmger atop a said transport frame shoulder; said corner post having a housing enclosing an internal space and extending between a lower foot face and a top; said corner post having, at said lower foot face, an aperture dimensioned to receive a said locating fmger into said internal space; said corner post further comprising guide surfaces enclosed within said housing and spaced apart to define a locking space and configured to snugly receive a said locating finger; each guide surface comprising a locking aperture; wherein a movable locking element is configured to engage both said locking apertures to thereby bridge said locking space; said locking element being configured to engage a lifting point at said locating finger; said movable locking element constituting the primary lifting element of said lifting yoke.

摘要： Transport frame and method; the transport frame having a longitudinal, lateral and upright extent, and being configured for receiving a tip portion of a longitudinally extending wind turbine blade, said frame being stackable with identical frames, said frame having a tip saddle assembly comprising a saddle with a support surface shaped to receive a blade tip with its chordwise extent lying approximately horizontal, and a clamping mechanism having a hinged clamping arm configured to be operable between a raised, open position and a lowered, closed position; said clamping arm, when open, allowing a blade tip to be lowered into said saddle with its chordwise extent generally horizontal, and when closed, securely restraining said blade tip against upward movement; said clamping arm extending between a hinge point and a free end; said tip saddle assembly further including a preventer serving to maintain said clamping arm in said closed position over a blade and which preventer has a middle portion extending between a first end and a second end; and wherein said tip saddle assembly further includes a fixing for respective said first and second end of said preventer; said tip saddle assembly being configured such that said preventer exerts a downward force on said clamping arm when a middle portion thereof passes under tension over a portion of said clamping arm between said hinge point and said free end, and wherein said preventer is anchored at said first and said second ends to said tip saddle assembly.

摘要： Transport frame pair configured for transporting a wind turbine blade, said frame pair comprising a tip frame and a root frame, each said tip and root frame being stackable with identical frames for blade transport or storage, each one of said tip and root frame comprising four upright frame struts which together define a generally cuboid internal space having a longitudinal extent between two pairs of said upright struts; said tip frame comprising a tip saddle assembly within said generally cuboid internal space, and said root frame comprising a root saddle assembly within said generally cuboid internal space, and wherein said root frame is configured to prohibit a translation movement of said root saddle assembly in a longitudinal direction of a blade supported in a root saddle of said root saddle assembly; and wherein said tip frame allows a translation movement of said tip saddle assembly in a longitudinal direction of a blade supported in a tip saddle of said tip saddle assembly. The longitudinal extent of the root frame may be more than twenty percent greater than the longitudinal extent of the tip frame.
