To provide a cable crane capable of stopping a hanging tool at a stopping time of a traverse trolley even if a distance from the traverse trolley to the hanging tool changes during the deceleration of the traverse trolley.SOLUTION: A cable crane 20 comprises: a transverse trolley 22 installed on a main rope 21 so as to move along the main rope 21; a winch 23 for driving the transverse trolley 22; a hanging tool 29 suspended from the transverse trolley 22; a first position measuring instrument 31 for measuring a position of the transverse trolley 22; a second position measuring instrument 32 for measuring a position of the hanging tool 29; and a control device 40. The control device 40 maintains the deceleration of the transverse trolley 22 if an oscillation angle of the hanging tool 29 is equal to a target value. The control device 40 decreases the deceleration of the transverse trolley 22 if the oscillation angle of the hanging tool 29 is greater than the target value. The control device 40 increases the deceleration of the transverse trolley 22 if the oscillation angle of the hanging tool 29 is smaller than the target value.SELECTED DRAWING: Figure 1

    【課題】横行トロリーの減速中に横行トロリーからバケット等の吊り具までの距離が変化しても、横行トロリーの停止時に吊り具を停止できるようにする。【解決手段】ケーブルクレーン20は、主索21に沿って移動するよう主索21に設置される横行トロリー22と、横行トロリー22を駆動するウインチ23と、横行トロリー22から懸下された吊り具29と、横行トロリー22の位置を計測する第1位置計測器31と、吊り具29の位置を計測する第2位置計測器32と、制御装置40と、を備える。吊り具29の振れ角度が目標値に等しければ、制御装置40が横行トロリー22の減速度を維持し、吊り具29の振れ角度が目標値より大きければ、制御装置40が横行トロリー22の減速度を減少させ、吊り具29の振れ角度が目標値より小さければ、制御装置40が横行トロリー22の減速度を増加させる。【選択図】図1
