To provide a crane with a hoisting synchronizing function which load sharing for each hook is synchronized by interlocking the co-hoisting of 3 or more hooks.SOLUTION: A speed control of winding motors IM for multiple hooks H11-H41 is performed so that a motor speed decreases as the motor load increases and the motor speed increases as the motor load decreases when winding up, and the motor speed decreases as the motor load increases and the motor speed decreases as the motor load decreases when winding down.SELECTED DRAWING: Figure 1

    【課題】3個以上のフックを共吊り連動させ、各フックの負荷分担が同調する巻上同調機能付きクレーンを提供する。【解決手段】複数のフックH11~H41の巻上げモータIMの速度制御を、巻上げ時においては、モータ負荷が大きくなるとそれにつれて速度が遅くなり、モータ負荷が小さくなるとそれにつれて速度が速くなるように、巻下げ時においては、モータ負荷が大きくなるとそれにつれて速度が速くなり、モータ負荷が小さくなるとそれにつれて速度が遅くなるように、制御する。【選択図】図1
