To provide an iron tower construction method capable of carrying out iron tower construction more easily and at lower cost than conventionally.SOLUTION: This iron tower construction method comprises: a step of arranging a climbing crane having an outrigger having a mast installation part provided on the center and extending in a cross shape, a mast disposed in the mast installation part of the outrigger so as to be able to change the height of the mast, and a crane body supported on the mast, outside an iron tower construction area with the height of the mast set as a first mast height; a first assembling step of lifting an iron tower material by the climbing crane and assembling an iron tower up to a first iron tower height; a mast height setting step of setting the mast height to a second mast height higher than the first mast height, and disposing, between the mast and the iron tower, a mast support for supporting the mast; and a second assembling step of lifting the iron tower material by the climbing crane and assembling the iron tower up to a second iron tower height higher than the first iron tower height.SELECTED DRAWING: Figure 1

    【課題】従来に比べて簡易に低コストで鉄塔建設を行うことのできる鉄塔建設工法を提供する。【解決手段】十字状に延在し中央部にマスト設置部が設けられたアウトリガーと、アウトリガーのマスト設置部に配設され高さを変更可能とされたマストと、マストの上部に支持されたクレーン本体とを有するクライミングクレーンを、マストの高さを第1マスト高として鉄塔建設領域の外側に配設する工程と、クライミングクレーンで鉄塔材を吊り上げて鉄塔を第1の鉄塔高さまで組み立てる第1組み立て工程と、マストの高さを第1マスト高より高い第2マスト高に設定するとともに、鉄塔との間にマストを支えるマスト支えを配設するマスト高さ設定工程と、クライミングクレーンで鉄塔材を吊り上げて鉄塔を第1の鉄塔高さより高い第2の鉄塔高さまで組み立てる第2組み立て工程と、を具備している。【選択図】図1
