To provide a transfer method of a hoisted load and a crane capable of early determining whether or not the swing of the hoisted load, which is caused in transferring the hoisted load by being hoisted with a rope by the crane, is increased with the lapse of time.SOLUTION: The swing stop control for stopping the swing of a hoisted load, which is caused in transferring the hoisted load by using a crane, is performed. During the generation of swing of the hoisted load or during the swing stop control, a physical amount of at least one of a prediction value of a maximum swing angle of the swing of the hoisted load, an energy flow rate per unit mass of the hoisted load that flows into the hoisted load from the trolley transferring the hoisted load, and an accumulated energy amount per unit mass of the hoisted load that is accumulated in the hoisted load is calculated. As a result of the calculation of the physical amount, the transfer of the hoisted load is stopped when the physical amount deviates from an allowable range.SELECTED DRAWING: Figure 3
【課題】クレーンにおいて吊り荷をロープで吊り上げて吊り荷を移送するときに発生する吊り荷の振れが、時間とともに大きくなるか否かを、早期に判定することができる吊り荷の移送方法及びクレーンを提供する。【解決手段】クレーンを用いて吊り荷の移送をするときに発生する吊り荷の振れを止める振れ止め制御を行う。この吊り荷の振れの発生中あるいは振れ止め制御中、前記吊り荷の振れの最大振れ角度の予測値、吊り荷を移送するトロリから前記吊り荷に流入する前記吊り荷の単位質量当たりのエネルギ流量、及び前記吊り荷に蓄積された前記吊り荷の単位質量当たりの蓄積エネルギ量の少なくとも一つの物理量を算出する。この物理量の算出の結果、前記物理量が許容範囲を外れた場合、前記吊り荷の移送を停止する。【選択図】 図3
