To provide a girder crane capable of accurate positioning of stoppage.

One end of a traveling chain 31 is connected to a tension bolt 39, and the tension bolt 39 is supported so as to move in a direction pulling the traveling chain 31. The traveling chain 31 is energized with tension force by energizing thereof with repulsive force of a spring 45 via the tension bolt 39. Thus, when a drive sprocket meshed with the traveling chain 31 is rotatively driven, the girder crane is moved and positioned along a guide rail laid on a frame 17 of a steel material storehouse, and desired steel materials are supplied to a finishing machine and the like from the steel material storehouse.
