Abstract

An unloading system for use in a storage structure having a sidewall that contains granular stored material. A reclaiming portion is spaced from the sidewall and has a floor portion that extends from a discharge opening toward the sidewall. The floor portion of the reclaiming portion is supported above the floor of the storage structure. The reclaiming portion may move with respect to the sidewall and is isolated from movement with respect to the sidewall of the storage structure. Seals between the reclaiming portion and the sidewall prevent the stored material from bypassing the reclaiming portion so that any discharge of the stored material occurs through the discharge opening.
