Summary:To provide a hanging load monitoring system for a crane capable of realizing more reliable safety measures than before.SOLUTION: The system comprises: cameras 10 and 11 installed at positions where a hanging load 8 on an overhead crane 1 (a crane) can be photographed; and an arithmetic unit 13 that determines by image analysis whether or not a person (a ground worker 9) is present in a dangerous area around the hanging load 8 on the basis of image data 10a and 11a of the cameras 10 and 11. The arithmetic unit 13 is configured to output at least one of an alarm signal and an emergency stop signal if it is determined that a person (the ground worker 9) exists in the dangerous area around the hanging load 8.SELECTED DRAWING: Figure 1 【課題】従来よりも確実性の高い安全対策を実現し得るクレーンの吊り荷監視システムを提供する。【解決手段】天井クレーン１（クレーン）における吊り荷８を撮影可能な位置に装備されたカメラ１０，１１と、該カメラ１０，１１の画像データ１０ａ，１１ａに基づき吊り荷８周囲の危険領域に人（地上作業員９）が存在しているか否かを画像解析により判定する演算装置１３とを備え、吊り荷８周囲の危険領域に人（地上作業員９）が存在していると判定された場合に警報信号及び非常停止信号の少なくとも何れか一方を出力するように前記演算装置１３を構成する。【選択図】図１
