Zusammenfassung: | A stacker crane includes a platform disposed between a pair of front and back masts disposed in a vertical direction. The platform includes a horizontal frame with a transfer device mounted thereon and vertical frames extending from front and back ends of the horizontal frame along the masts. The platform is raised or lowered with the vertical frames suspended. The vertical frames each include a pair of first guide rollers sandwiching one of the masts in a lateral direction perpendicular or substantially perpendicular to a front-back direction and are each connected to the horizontal frame to be rotatable with respect to the horizontal frame using the lateral direction as an axis. |
