Shuttle rack is a high-density automatic storage system composed of rack body, intelligent shuttle car and supporting forklifts. The shuttle car automatically transports pallets on rack tracks without forklifts driving inside the racks, balancing high storage density and goods access efficiency. Advantages: high warehouse space utilization, convenient inbound & outbound operations, low equipment maintenance cost and excellent overall safety performance. It supports both FIFO (First In First Out) and FILO storage modes, suitable for mass dense storage industries including food, alcohol, cold chain, auto parts and grain & oil.
