Shuttle Rack L" is a dolly-type pallet storage system suitable for high density storage of low SKU items at reasonable cost and short lead time. The system consists of racks with lanes, battery-powered dollies, and battery chargers. Forklift places a dolly at the necessary lane before selecting an operation mode using the remote controller. The number of dollies can be adjusted to match throughput. The Shuttle Rack L's simple configuration makes it easy to add more dollies and racks after installation.
