SLSs (Shuttle Loop System) are Cassioli’s RGV systems consisting of several rapid and independent self-propelled, self-steering, mobile units moving on a closed circuit consisting of monorail loop. Cassioli’s RGV system is a fast, flexible and easy-install method of transporting large quantities of heavy goods over long distances, at low cost and with high efficiency. Cassioli SLSs are perfectly adapted to the customer’s needs, differing according to weight and size, single or multiple load, and function and type of load. Various types of materials can be loaded on SLS shuttles, such as pallets, boxes, cartons, trays, racks, skids, finished products, semi-finished and raw materials.
