PROBLEM TO BE SOLVED: To provide a building intermediate story installation type crane device which enables direct transportation work of a building to an intermediate story accompanied with lifting and lowering of heavy objects.SOLUTION: A crane device 100 for hanging heavy objects in a state of projecting substantially horizontally outward from an intermediate story of a building provides: a first structure body 110 supporting a trolley portion 130; a second structure body 120 which supports the first structure body 110 substantially horizontally and which can be inserted through with different inner and outer diameters; a trolley portion for lifting and lowering a hook portion 140; first structure body sliding means 150; trolley portion sliding means 160; and a heavy object winding mechanism 170. The first structure body sliding means 150 allows the first structure body 110 to slide in a substantially horizontal direction from the second structure body 120, and expands and contracts the entire length in the substantially horizontal direction. After the trolley portion 130 is slid and positioned by the trolley portion sliding means 160, the hook portion 140 is lifted and lowered by the heavy object winding mechanism 170.SELECTED DRAWING: Figure 1

    【課題】 重量物の昇降を伴う建物の中間階への直接の搬送作業を可能とする建物中間階設置型クレーン装置を提供する。【解決手段】 建物の中間階から外へ略水平に突出させた状態で重量物を吊下するクレーン装置100であって、トロリ部130を支持する第1構造体110と、第1構造体110を略水平に支持するとともに内外径を相違させて挿通し合えるものとした第2構造体120と、フック部140を昇降するトロリ部と、第1構造体摺動手段150と、トロリ部摺動手段160と重量物巻き上げ機構170を備えている。第1構造体摺動手段150により第1構造体110を第2構造体120から略水平方向にスライド移動できるようにし、全体長を略水平方向に伸縮させる。トロリ部摺動手段160によりトロリ部130を摺動させ、位置決めした後、重量物巻き上げ機構170によりフック部140を昇降させる。【選択図】 図1
