Lista International Corporation’s STAK System pallet-based storage and handling system is based on a system of dynamically adjustable pallets (rather than fixed shelves) and a captive lifting and handling device. This helps maximize storage density by minimizing the vertical space requirements of each stored pallet and its contents. The system is modular, with add on bays that allow the system to grow as capacity needs do. Its handling device makes removing even large loads easier. Loaded pallets are removed and replaced by guiding the mast to a new position, where the pallets can then be extracted. The handling device also maneuvers on four axes, creating 360° flexibility and allowing for simple, intuitive positioning. The controls do not require a license or certification to operate.
