Trends in the Development of High-Density Pallet Stacker Automated Storage and Retrieval Systems

Currently, there are two common solutions in the market: the stacker crane vertical storage system and the shuttle car vertical storage system. The latter offers high automation, but due to the necessity of setting up stacker crane aisles, it cannot fully utilize the storage space, resulting in a lower storage capacity. On the other hand, the shuttle car vertical storage system requires coordination with high-level forklift operation, which boasts high space utilization but, due to its semi-automatic operation, it's challenging to establish a rational information management system, significantly reducing the overall efficiency of the warehousing process and the company's level of informatization.

It addresses the inconvenience of traditional stacker systems that occupy a large number of storage positions in high-rise warehouses, thus minimizing actual storage space. It optimizes storage capacity and throughput efficiency, representing a novel application model. The high-density stacker system, powered by advanced WMS and WCS information systems, not only meets the basic needs of users but also considers operational efficiency and user experience.
