Abstract
A stacker crane capable of improving space efficiency of a rack, and reducing cost for equipment using the stacker crane, without complicating structures of masts and a platform, includes a truck frame that travels on a track along a rack, a mast provided on the truck frame, and a platform that is raised and lowered along the mast. The mast includes a first mast that guides the platform, and a second mast located such that the platform is sandwiched between the first mast and the second mast in a travelling direction of the truck frame. As compared with the first mast, the second mast has a small width in the travelling direction of the truck frame, and has the same width as seen from the travelling direction.
