Lattice-skin hybrid tower

A device for attaching two sections of a wind turbine tower comprising:

• a tapered pin attached to a first tower section with a transverse hole provided in said pin;
• a body attached to a second tower section with a tapered cavity for receiving said tapered pin with a transverse hole provided in said body;
• and
• a bolt inserted through the transverse holes in said pin and said body to fasten said pin and said body together.

A method of assembling a wind turbine tower comprising the steps of:

• providing a tower section that is divided into a plurality of radial segments;
• providing a frame that is capable of supporting said radial tower segments;
• attaching said radial tower segments to said frame;
• and
• fastening said radial tower segments to each other.

An assembly device for a wind turbine tower wherein said tower comprises a plurality of radial segments, said assembly device comprising:

• a first frame for supporting a first end of each said radial segment of said tower;
• a second frame for supporting a second end of said radial segment of said tower;
• and
• a mechanism for adjusting said first frame relative to said second frame whereby said radial segments may be properly aligned during assembly.

A method of assembling a wind turbine tower comprising the steps of:

• providing a tower section that is divided into a plurality of radial segments;
• supporting each of said tower segments substantially horizontally;
• aligning said tower segments relative to each other;
• and
• fastening said radial tower segments to each other.

A method of assembling a wind turbine tower comprising the steps of:

• providing a tower section that is divided into a plurality of radial segments;
• supporting each of said tower segments substantially vertically;
• aligning said tower segments relative to each other;
• and
• fastening said radial tower segments to each other.
