Mobile rack is a very high density storage system with 100% utilization of pallet positions. The system is comprised of 100% selective back-to-back pallet racks mounted on mobile bases that travel on tracks laid into the floor. The storage carriages are driven by integral electric motors and can be moved individually or as a section, permitting access to any pallet at any time.

Mobile rack is particularly effective in cold or ultra-cold warehouses and other industrial applications where aisle space is at a premium and speed of product movement is not a major concern.
