Abstract
The invention relates to a wind turbine tower access panel, which panel is removably fixable at a service aperture in a tower wall to thereby close said aperture; said access panel being generally planar and extending radially about an axis normal thereto, said access panel comprising a set of two or more fixing elements configured to securely fix said access panel in place at a said aperture; wherein each said fixing element comprises an axial clamp, said clamp comprising an anchor fixed to said access panel, a clamping force adjuster and a clamp head having a clamping surface; said clamp head comprising a relatively deformable resilient material which deforms under an applied clamping load of said clamp thereby applying a clamping force to said tower wall.

Wind turbine tower access panel, which panel is removably fixable at a service aperture in a tower wall to thereby close said aperture;
- said access panel being generally planar and extending radially about an axis normal thereto,
- said access panel comprising a set of two or more fixing elements configured to securely fix said access panel in place at a said aperture;
- wherein each said fixing element comprises an axial clamp, said clamp comprising an anchor fixed to said access panel, a clamping force adjuster and a clamp head having a clamping surface;
- said clamp head comprising a relatively deformable resilient material which deforms under an applied clamping load of said clamp thereby applying a clamping force to said tower wall.
Wind turbine tower comprising a longitudinally extending generally cylindrical wall said tower defining an interior region within said wall and an exterior outwith said wall;
- said tower wall being provided with a service aperture in its base region, which aperture extends radially in said wall about an axis normal thereto and is dimensioned to allow passage of personnel and equipment between said exterior and said interior region;
- wherein said tower further comprises an access panel removably fixed at said tower aperture;
- said access panel being an access panel according to any previous claim.
