A combined door and platform assembly for an air preheater having a housing with an access opening. The assembly includes a door frame which is fixedly mounted to the outer surface of the housing around the access opening. The bottom portion of a base is permanently, pivotally mounted to the door frame. The base is moveable from a vertical position, where the base acts as a door closing the access opening, to a horizontal position, where the base acts as a platform to facilitate removal and replacement of basketed materials disposed within the housing.
