PROBLEM TO BE SOLVED: To provide a crane in which it is possible to obtain a large base line length defined as distance between optical axes of a pair of monitoring cameras when two monocular monitoring cameras are provided to configure a stereo camera and image processing is performed by capturing an image with the stereo camera.SOLUTION: The crane has an operation monitoring device in which two monocular monitoring cameras 2A and 2B are provided for configuring a stereo camera to capture an image and which performs image processing. When a direction orthogonal to an extending direction of a boom that can extend and tilt is a width direction of the boom, two monocular monitoring cameras 2A and 2B in which distance between optical axes of the cameras is defined as a base line length D are provided at both ends in the width direction of the head 17d of the boom. |
