To provide a pendulum length setting device used for controlling a crane swinging stop, which is capable of suppressing load swinging by appropriately setting a pendulum length.SOLUTION: The pendulum length setting device is provided with: rope length detection means for identifying a first distance Lf from an unwinding position G0 of a rope 4 of a hoist 3 which becomes a pendulum fulcrum position to a gravity center position Gf of a suspension tool 5; input means for inputting a second distance Lw from the gravity center position Gf of the suspension tool 5 to a gravity center position Gw of a suspended load 7 suspended via a sling rope 6; and display means for visibly displaying a pendulum length Ls calculated by adding together the first distance Lf and the second distance Lw.SELECTED DRAWING: Figure 1

    【課題】振り子長を適切に設定することによって、荷振れを抑制することができるクレーンの振れ止め制御に用いる振り子長の設定装置を提供すること。【解決手段】振り子の支点位置となる巻上装置3のロープ4の巻き出し位置G0から吊下具5の重心位置Gfまでの第1の距離Lfを特定するロープ長検出手段と、吊下具5の重心位置Gfから玉掛けロープ6を介して吊り下げられた吊荷7の重心位置Gwまでの第2の距離Lwを入力するための入力手段と、第1の距離Lf及び第2の距離Lwを合算して算出される振り子長Lsを可視的に表示する表示手段とを備える。【選択図】図1
