Abstract

A crane device according to one embodiment of the present invention comprises a movable rail, a lifting device, a movement limiting device, and a limit switch. The lifting device comprises a second moving part and a protruding part. The second moving part is coupled to the movable rail and moves along the movable rail. The protruding part protrudes in a predetermined protruding direction. The movement limiting device comprises a coupling part, an extension part, and a movement limiting part. The coupling part surrounds the protruding part. The extension part extends from the coupling part in a predetermined extension direction. The movement limiting part is spaced apart from the coupling part and is positioned on one side of the extension part. The limit switch is operated by the protruding part, the coupling part, or the movement limiting part depending on the position of the lifting device and the extension direction, and controls the operation of the second moving part.
