  • Publication number: 20230373716
    Abstract: A stocker includes a crane to travel on a travel route, a maintenance area on an extension of the travel route, a controller to cause the crane to travel toward the maintenance area, a first sensor to detect that the crane is positioned at an entry position, and a second sensor to detect that the crane has arrived at a stop position. The controller is configured or programmed to control the crane to decelerate in accordance with a detection result of the first sensor and control the crane to stop in accordance with a detection result of the second sensor.

  • Publication number: 20220177014
    Abstract: A damping device includes a damper provided to an outer end of a stacker crane in a traveling direction. The damper includes: a rod member extending along the traveling direction; a first biasing member configured to bias the rod member outward in the traveling direction; and a movement restriction mechanism configured to allow inward movement of the rod member in the traveling direction and restrict outward movement of the rod member in the traveling direction when the rod member has moved inward in the traveling direction.
