PROBLEM TO BE SOLVED: To provide a crane anti-sway control method and system that can hoist up and/or hoist down a hoisting load during travelling of a crane and also prevent residual sway of the hoisting load.SOLUTION: A crane anti-sway control method includes: changing a rope length in a section B where acceleration of a crane 1 is constant and swaying angle θ of a hoisting load 3 is constant; and setting an accelerating time Cto Cof the crane 1 after the section B based on a swaying cycle of the hoisting load 3 after the rope length is changed.SELECTED DRAWING: Figure 5

    【課題】クレーンの走行中に吊荷の巻き上げ及び/又は巻き下げが可能であり、吊荷の残留振れも防止できるクレーンの振れ止め制御方法及びシステムを提供する。【解決手段】クレーン1の加速度が一定で吊荷3の振れ角θが一定の区間Bでロープ長を変化させる。そして、ロープ長が変化した後の吊荷3の振れ周期に基づいて、前記区間B後のクレーン1の加速時間C1〜C3を定める。【選択図】図5
