Abstract

An automated warehouse includes a storage shelf, a stacker crane, and a maintenance facility. The maintenance facility includes a work stage. The work stage includes a mast penetration portion, a stage scaffold, and a support frame configured to support the stage scaffold. The stage scaffold includes a fixed scaffold fixed to the support frame, and a movable scaffold. The movable scaffold is changeable between a first retracting posture in which the movable scaffold does not come into contact with the path of the mast and which does not allow the movable scaffold to function as a scaffold for the operator and a first deployment posture in which the movable scaffold comes into contact with the path of the mast but does not come into contact with the mast of the stacker crane at a maintenance position and which allows the movable scaffold to function as the scaffold for the operator.
