The Commissioner XL is a compact high-performance vertical storage/sortation system which provides order-fulfillment and sortation capabilities in ambient, refrigerated and freezer environments. It is ideally suited for WIP buffering, product staging, order consolidation, order picking, and sortation prior to shipping or palletizing. Ideal applications include route stop sequencing, store aisle sequencing, or sequencing products for palletizing. The load handler stores and retrieves loads by traveling horizontally along the lifting beam, which moves up and down to the correct storage position. Typically integrated into a system, the sortation system can be used as a single unit or multiple units. When multiple units are integrated, routine maintenance can be performed on one system without interrupting the workflow.
