Overview
The RapidStore ML450 is a compact, high-density Mini-load storage and staging device designed to enhance various applications such as goods-to-person order fulfillment, pick module replenishment, in-process buffer staging, mixed case palletizing, and order consolidation. It supports production, warehousing, and distribution operations by efficiently bringing materials to the point of use.

System Description
The RapidStore ML450 is a single mast, computer-controlled storage and retrieval machine (SRM) that operates on a floor rail and is stabilized overhead with a steel guide tube. It features a load platform that moves vertically using a steel rope hoist system, capable of picking or depositing loads on either side of the SRM.

Load Handling
The system accommodates various load types such as pallets, totes, trays, or pans, with load footprints ranging from 30" by 48" to 48" by 48". The load handling device is engineered to match the load footprint, utilizing chain-driven extraction fingers for metal pans.
