PROBLEM TO BE SOLVED: To provide a crane and a method of controlling the crane suppressing a wire rope from colliding with a structure and the like of the crane due to the wire rope being flapped by wind.SOLUTION: A rope tensioning device 11 is disposed between a trolley 3 and a hanger 5 for preventing the hanger 5 ascending as a wire rope 4 being wound up from approaching the trolley 3. The hanger 5 is caused to ascend by the wire rope 4 being wound up and thereby the rope tensioning device 11 is put into a sandwiched sate between the trolley 3 and the hanger 5. Then, tensile force of the wire rope 4 is to be increased by the wire rope 4 being wound up further.SELECTED DRAWING: Figure 2

    【課題】ワイヤロープが風に煽られてクレーンの構造体等に衝突することを抑制するクレーンおよびクレーンの制御方法を提供する。【解決手段】ワイヤロープ4の巻上げにともない上昇する吊具5がトロリ3に接近することを阻止するロープ緊張装置11をトロリ3と吊具5との間に配置して、ワイヤロープ4の巻上げにより吊具5を上昇させて、トロリ3と吊具5との間にロープ緊張装置11が挟まれた状態とした後に、ワイヤロープ4をさらに巻上げることによりワイヤロープ4の張力を増大させる。【選択図】図2
