The vertical storage module is a self-supporting elevator with external cladding, consisting of trays arranged vertically that are stored at the front and rear of the structure. A mechanism for storage and retrieval of trays automatically searches and delivers trays at the touch of a screen or barcode scanning. It allows for the simultaneous picking of multiple orders. The equipment also maximizes vertical storage, allowing for reduced occupied area. Additionally, the system is prepared for integration with existing ERP or WMS for data exchange.
