PROBLEM TO BE SOLVED: To construct a large wind power generator having height exceeding 50m even at a detached island or a mountain district at a low cost without using high-cost equipment. SOLUTION: A temporary tower 3 is assembled from below to above by using a climbing crane 2. After a nacelle 6 to contain a generator is transferred from a ground to the top part of the temporary tower by a lifting mechanism 5, by using hoisting mechanism 7 arranged at the top of the temporary tower 3, the tower 8 is assembled from below to above. The nacelle 6 to contain a generator is attached by using the lifting mechanism 5 to the upper part of the tower 8. Thereafter, after by climbing crane 2, the temporary tower 3 is disassembled, blades 10 are attached. |
