The new storage system, called the Multi-Level Shuttle (MLS), is formed by compact, single mini stacker cranes, however offering high performance, which can be stacked in the same lane, increasing system throughput. Cassioli’s MLS was designed for storage of different types of materials and products, from Green Tires to finished tires. In an automatic warehouse with single or double depth, the Multi-Level Shuttle works on specific storage shelves and is presented as a shuttle with light design, capable of reaching higher performances than traditional stacker cranes for storage/retrieval. Having various shuttles on one another available means more flexible configuration is possible of the warehouse and the modularity of the system allows its development based on needs, the production potential required by the client and the type of product to handle. The compact design and the reduced weight contribute to making the system more dynamic, guaranteeing greater production capacity, with a high storage density, high efficiency from an energy point of view and low maintenance costs. Like all Cassioli systems, the Multi-Level Shuttle is managed by software developed inhouse, equipped with a simple and intuitive interface and capable of interacting perfectly with the client management software.
