To provide a collision prevention control system for a crane being an automatic crane simultaneously performing hoisting/lowering operation and horizontal movement so as to enable efficient operation, the collision prevention control system capable of preventing collision between a suspended load and a floor obstacle even when the crane is stopped while the hoisting/lowering operation and the horizontal movement are performed.SOLUTION: In a collision prevention control system for a crane, when an automatic crane CR is hoisted obliquely through a shortest path FR in hoisting operation and horizontal movement in simultaneous execution of the hoisting operation and the horizontal movement on the automatic crane CR, an actual moving path is set rearward in a horizontal movement advancing direction from the shortest path FR only by a braking distance BD relative to a speed at which the horizontal movement occurs.SELECTED DRAWING: Figure 1

    【課題】巻上げ下げと水平移動の同時動作を行い、効率的な動作を可能とした自動クレーンにおいて、巻上げ下げと水平移動を行っている時にクレーンが停止しても、吊荷と床上障害物と衝突することを防止することができるクレーンの衝突防止制御システムを提供すること。【解決手段】自動クレーンCRの巻上げと水平動作を同時に行う時、巻上げと水平動作で最短経路FRで斜めに巻上げる時、水平動作の発生速度に対する制動距離BD分だけ、最短経路FRから水平動作進行方向の後方に実際の移動経路を設定する。【選択図】図1
