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.
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.
