Title:
CRANE SWAY SENSOR AND CRANE
Document Type and Number:
WIPO Patent Application WO/2011/102165
Kind Code:
A1
Abstract:
A crane sway sensor capable of accurately detecting sway using a simple configuration.
A crane sway sensor is provided with: an image-capturing section (10) which is provided to the crane body (C) and is oriented below the crane body (C); and a target section (20) which is provided to a lifting device (W) suspended from the crane body (C) and facing the image-capturing section (10) and which has an LED array element for emitting illumination light upward and having a light emitting surface formed by LED chips arranged in an array. If the minimum distance from the center of gravity of the light-emitting surface of the target section (20) to the edge thereof is d, the maximum stroke between the image-capturing section (10) and the target section (20) is LMAX, and the instantaneous angle of field of view of the image-capturing element of the image-capturing section (10) is Q, the crane sway sensor satisfies the following relationship:
Q × LMAX < d
