To provide a detection method capable of ensuring quick response at a construction site by immediately determining the turning angle of a suspended load even with a simple structure where the number of components has been reduced.SOLUTION: This detection method includes: the step (a) of causing a control unit to store a reference shape formed by one rotational asymmetrical shape in advance; the step (b) of imaging the reference shape (hereinafter, referred to as imaged shape) by using one imaging device which is provided to a gib during transportation of a suspended load, and causing the control unit to store the imaged shape; the step (c) of comparing the imaged shape with the reference shape and performing a matching operation; and the step (d) of detecting an angle so as to determine how many times the imaged shape has rotated with respect to the reference image through the matching operation.SELECTED DRAWING: Figure 2

    【課題】部品点数を減らすとともにシンプルな構造であっても、吊荷の旋回角度を即時に判断し、建設現場での対応を確実に素早くできる検出方法を提供する。【解決手段】予め1つの回転非対称形状で構成された基準形状を制御部に記憶させる工程(a)と、吊荷を運搬中にジブに設けた1つの撮像装置を用いて基準形状を撮像し(以下、撮像形状という)、撮像形状を前記制御部に記憶させる工程(b)と、前記基準形状と前記撮像形状とを比較し、マッチング操作を行う工程(c)と、前記マッチング操作により、撮像形状が基準形状に対して何度回転しているかを角度検出する工程(d)とを含む。【選択図】 図2
