Against the backdrop of the rapid development of Suzhou’s smart manufacturing industry, automated stereoscopic warehouses, as an efficient and intensive smart warehousing solution, have been widely adopted across local sectors including manufacturing, e‑commerce, pharmaceuticals and food. A complete automated stereoscopic warehouse system in Suzhou is not merely a simple combination of individual equipment, but an integrated organic whole formed by the coordinated operation and mutual support of multiple core modules. Each component performs its own dedicated function to jointly realize fully automated processes of cargo storage, handling, sorting and management.Combined with local application scenarios in Suzhou, this article elaborates on the core components of the system, helping enterprises fully understand the structure and functions of automated stereoscopic warehouses and providing references for project selection, configuration and daily operation and maintenance.The composition of Suzhou’s automated stereoscopic warehouse system centers on four core demands: storage, handling, control and management. It covers multiple dimensions including mechanical structures, automated equipment and intelligent systems. Each component adapts to the warehousing needs of local enterprises in different industries and can be flexibly configured according to actual scenarios to ensure efficient and stable system operation. The specific components are detailed as follows:

I. Stereoscopic Racking System

As the core load-bearing component of the automated stereoscopic warehouse, the stereoscopic rack forms the foundation for dense cargo storage and improved space utilization, and is also one of the most intuitive parts of Suzhou automated warehouse systems.Adopting a multi-layer vertical design, the racks make full use of warehouse vertical space and deliver noticeably higher storage density than traditional flat warehouses, well suiting the land resource constraints prevalent in Suzhou. Mostly made of high-strength steel and processed through pickling, phosphating and electrostatic spraying, the racks feature corrosion resistance, wear resistance and strong load-bearing capacity. Storage slot dimensions can be customized according to cargo size and weight. Common types include beam-type racks, shuttle racks and cantilever racks.Beam-type racks suit the storage of most general goods and are widely used in Suzhou’s e-commerce and manufacturing industries. Shuttle racks are ideal for dense storage scenarios and fit batch inventory management in the food and pharmaceutical sectors. Cantilever racks apply to oversized and long-shaped goods, matching the demands of Suzhou’s machinery manufacturing and hardware processing industries. Rack design and installation are tailored to local warehouse dimensions in Suzhou to ensure reasonable layout and reserve sufficient space for subsequent automated equipment operation.

II. Automated Handling Equipment System

This system serves as the core link for automated cargo circulation, responsible for transporting goods between racks, sorting areas and inbound/outbound platforms. It replaces traditional manual handling, improves operational efficiency and reduces human errors.Three main types of automated handling equipment are commonly adopted in Suzhou automated stereoscopic warehouses:First, aisle stacker cranes. Acting as warehouse handling robots, they travel along rack aisles to complete inbound, outbound and storage location adjustment tasks. Capable of vertical lifting, horizontal movement and fork extension, they deliver precise positioning and stable operation to adapt to racks of varying heights.Second, AGV/AMR autonomous guided vehicles. Mainly used for short-distance cargo transfer inside the warehouse, they operate without manual driving. By adopting navigation methods such as laser and QR code positioning, they independently plan travel routes and move flexibly across warehouse areas, well fitting the high-frequency and multi-batch transfer demands of Suzhou’s e-commerce and pharmaceutical industries.Third, conveyor systems, including roller conveyors and belt conveyors. They undertake connecting transportation between different equipment, such as delivering inbound goods to stacker crane working areas and transporting outbound goods to sorting zones or loading platforms, achieving seamless cargo flow connection.

III. Electrical Control System

The electrical control system acts as the nerve center of the automated stereoscopic warehouse, coordinating the operation of all automated equipment and ensuring precise, well-coordinated movements across all procedures.It mainly consists of power distribution cabinets, PLC controllers, sensors, emergency stop devices and lighting systems, with core functions including equipment motion control, operating status monitoring and fault alarming.As the core control unit, the PLC controller receives instructions from the intelligent management system and precisely regulates the running speed, position and action sequence of stacker cranes, AGVs, conveyors and other devices. Sensors collect equipment operating data, cargo position information and environmental parameters such as temperature and humidity, feeding real-time data back to the control system to guarantee operational safety. Safety components such as emergency stop devices and guardrails enable immediate equipment shutdown during abnormal conditions to eliminate potential hazards and comply with safety management regulations across industries in Suzhou.The deployment of the electrical control system strictly follows national electrical safety standards with proper insulation and grounding treatment, adapting to the power consumption requirements of local enterprises in Suzhou.

IV. Intelligent Management System

The intelligent management system serves as the core enabling digital and intelligent management for automated stereoscopic warehouses, taking charge of overall scheduling for all warehouse business processes and realizing visualized inventory management, automatic task scheduling and real-time data traceability.Common intelligent management systems adopted in Suzhou automated stereoscopic warehouses mainly include the WMS Warehouse Management System and WCS Equipment Control System. The two operate collaboratively to form a complete management framework.The WMS is mainly responsible for inventory management, covering functions such as storage location allocation, inventory counting, order processing and data statistics. Enterprises can check inventory status, product batches and inbound and outbound records in real time through the system, accurately controlling warehousing workflows and reducing inventory overstock.The WCS focuses on equipment scheduling. According to instructions issued by WMS, it automatically assigns operation tasks, optimizes equipment running routes, and coordinates the collaborative operation of stacker cranes, AGVs, conveyors and other facilities to improve overall operational efficiency.Some automated stereoscopic warehouses of Suzhou enterprises are further integrated with the MES Manufacturing Execution System and ERP Enterprise Resource Planning System, achieving seamless connection between warehousing, production and sales, and enhancing supply chain collaboration efficiency.

V. Auxiliary Systems

Although auxiliary systems do not directly participate in cargo storage and handling, they play a vital role in ensuring the stable operation of automated stereoscopic warehouses and optimizing overall operational experience, adapting to personalized demands of different industries in Suzhou.Common auxiliary systems are as follows:First, Environmental Control System. Widely applied in pharmaceutical, food and other industries with special storage environment requirements, it enables precise regulation of temperature and humidity. Equipped with ventilation, dehumidification and constant-temperature devices, it guarantees safe cargo storage and complies with GMP certification, food hygiene and other relevant standards.Second, Safety Protection System. Apart from the safety components inside the electrical control system, it also includes rack guardrails, cargo anti-falling devices, video surveillance systems and other facilities to fully protect the safety of personnel, equipment and goods.Third, Fire Protection System. Deployed in accordance with warehouse fire protection codes, it is equipped with fire extinguishers, fire hydrants, smoke detectors and other devices. Regular fire safety inspections are conducted to meet local fire acceptance standards in Suzhou.Fourth, Operation and Maintenance Auxiliary System. It includes equipment inspection modules and fault diagnosis modules, which monitor real-time equipment operating status, detect potential hidden risks in a timely manner, provide maintenance guidance for operation and maintenance staff, and extend equipment service life.The above five major components collaborate closely and are indispensable, jointly forming a complete automated stereoscopic warehouse system for Suzhou.Enterprises of different industries and scales in Suzhou can flexibly configure and customize each component according to their own warehousing demands, cargo characteristics and site conditions. For example, automated stereoscopic warehouses of pharmaceutical enterprises in Suzhou prioritize strengthening environmental control and traceability systems to meet compliance requirements; e-commerce enterprises in Suzhou focus on improving the coordination efficiency of automated handling equipment and intelligent management systems to adapt to high-frequency order processing demands.With the continuous iteration of smart manufacturing technologies in Suzhou, the composition of automated stereoscopic warehouse systems is also being continuously optimized. New functions such as digital twin and IoT remote monitoring have been added to further elevate the system’s intelligence level, providing stronger support for the warehousing upgrading of local enterprises in Suzhou.
