A method for assembling a wind turbine tower on an erection foundation, in which method at least two ring elements, as high as part of the tower, are composed from concrete segments, and the ring elements are lifted in the assembly order to superimposed positions. The first ring element is lifted in an upright position to the vertical position of the next ring element, and locked at that height. The following ring elements are placed individually in the assembly order below the previous ring element and lifted with the previous ring element or the ring elements to the vertical position of the next ring element, and locked at that height. The last ring element is lifted into contact with the previous ring element and released connected together to hanging suspended state, and the superimposed ring elements are lowered onto the erection foundation. In addition the invention relates to the device for assembling a wind turbine tower on an erection foundation. |
