To provide a crane device capable of reducing an upper space required for operation thereof.SOLUTION: A crane device includes a suspension tool 28, a plurality of wires 30 for supporting the suspension tool 28, and a plurality of wire drive mechanism 32 performing winding and rewinding of each of the plurality of wires 30. Connection portions between the suspension tool 28 and the plurality of wires 30 are dispersed on a lower end side and an upper end side of the suspension tool 28. The suspension tool 28 can be expanded and contracted between the connection portion on the lower end side and the connection portion on the upper end side.SELECTED DRAWING: Figure 3
【課題】稼働に必要な上部空間を小さくできるクレーン装置を提供する。【解決手段】クレーン装置は、吊り具28と、吊り具28を支持する複数本のワイヤ30と、複数本のワイヤ30のそれぞれの送り出しおよび巻き取りを行う複数のワイヤ駆動機構32と、を備える。吊り具28と複数本のワイヤ30との連結箇所は、吊り部28の下端部側と上端部側とに分散される。吊り具28は、下端部側の連結箇所と上端部側の連結箇所との間において伸縮可能である。【選択図】図3
