To accurately measure, with a simple facility, an amount of shake of a load suspended by an overhead crane used for conveying a heavy object.SOLUTION: A shake measurement device 8 includes: a CMOS camera 10 that is fixed downward to a dolly 3 on a vertical line from a support point of a suspended load W on a suspending wire 5 supporting the suspended load W in an overhead crane 1, and continuously photographs vertically downward; a circular marker 9 a circular plane of which is horizontally fixed upward to a hook portion on the vertical line from the support point of the suspended load W; and arithmetic means 11 that measures a diameter based on an image of the circular marker 9 photographed by the CMOS camera 10 and continuously calculates drawn lengths and shake angles of the suspending wire 5.SELECTED DRAWING: Figure 2

    【課題】重量物の運搬に使用される天井クレーンの吊り荷の揺れ量を精度高く簡易な設備で測定する。【解決手段】振れ測定装置8は、天井クレーン1における吊り荷Wを支持する吊りワイヤ5の当該吊り荷Wの支持点から鉛直線上の台車3に下向きに固定され、鉛直下方を連続的に撮影するCMOSカメラ10と、吊り荷Wの支持点から垂直線上のフック部に円形平面を上向きに水平に固定される円マーカー9と、CMOSカメラ10で撮影した円マーカー9の画像に基づいて直径を測定し、吊りワイヤ5の繰り出し長さ及び振れ角を連続的に算出する演算手段11とを具備させた。【選択図】 図2
