PROBLEM TO BE SOLVED: To provide an overwinding detection device capable of detecting overwinding with higher accuracy by a simpler configuration.SOLUTION: An overwinding detection device 20 is configured by comprising: a position information calculation unit 24; a determination unit 25; a warning control unit 26; a winch control unit 27; and a storage unit 28. The position information calculation unit 24 calculates position information of hooks 11, 13 on the basis of an image P captured by a suspended load monitoring camera 15 which is provided to a boom 1 or a gib 18 of a crane vehicle 1. The determination unit 25 determines whether winding of wire ropes 10, 12 is overwinding on the basis of the position information. The warning control unit 26 notifies an operator of warning information when overwinding is determined. The winch control unit 27 stops the winding of the wire ropes 10, 12 which have determined to be overwinding. The storage unit 28 stores various pieces of information such as an overwinding detection program and a parameter used for overwinding detection.SELECTED DRAWING: Figure 2

    【課題】より簡易な構成で、より高精度に過巻を検出することができる過巻検出装置を提供する。【解決手段】過巻検出装置20を、位置情報算出部24と、判定部25と、警告制御部26と、警告制御部26と、ウインチ制御部27と、記憶部28とを備えて構成する。位置情報算出部24は、クレーン車1のブーム7又はジブ18に設けられた吊り荷監視カメラ15で撮影された画像Pに基づいて、フック11,13の位置情報を算出する。判定部25は、位置情報に基づいて、ワイヤロープ10,12の巻き上げが過巻であるか否かを判定する。警告制御部26は、過巻と判定されたときに警告情報をオペレータに通知する。ウインチ制御部27は、過巻が検出されたワイヤロープ10,12の巻き上げを停止させる。記憶部28は、過巻検出プログラム及び過巻検出に用いるパラメータ等の各種情報が記憶される。【選択図】図2
