PROBLEM TO BE SOLVED: To provide an operation method of the tower crane capable of improving stability with the cost reduction and of preventing the excessive moment and horizontal force from acting on the mast, frame and base.SOLUTION: It has the connecting process to connect the mast 2 to the base isolation structure 15 using the stay 16, the dividing process to divide the mast 2 into the upper and lower section in the connection part 17 installed at a lower position than the stay 16 connected in the connecting process, the pin supporting process to rotatably support the mast 2 at the connection part 17 while supporting the horizontal and vertical load acting on the mast 2 by the self-aligning type bearing interposed between the divided upper and lower mast 2 in the dividing process.SELECTED DRAWING: Figure 3
【課題】マスト、架台、基礎に過大なモーメントと水平力が作用することを防止し得、コストダウンを図りつつ安定性向上を図り得るタワークレーンの運用方法を提供する。【解決手段】免震構造物15に対しマスト2をステー16によってつなぐ接続工程と、接続工程でつないだステー16より下方位置に設定された連結部17でマスト2を上下に分断する分断工程と、分断工程で上下に分断したマスト2間に介装された自動調心形軸受により、マスト2に作用する水平荷重及び垂直荷重を支持しつつマスト2を連結部17において回動自在に支持するピン支持工程とを有する。【選択図】図3
