Warehouse Stacker Crane for AS/RS: High-Efficiency, Reliable, Fully Automated Storage

Warehouse stacker cranes are the core equipment of automated storage and retrieval systems (AS/RS). By operating automatically in three directions—X (aisle travel), Y (lifting), and Z (telescopic fork)—they achieve precise pallet handling and efficient material flow.

The intelligent warehouse stacker crane independently developed by KUANGSHAN CRANE has entered mass production. It features a simple structure, high positioning accuracy, stable operation, and full-process automation, making it the optimal choice for large-scale automated high-bay warehouses.

• The single-mast design is lighter, enabling faster inbound and outbound response with high positioning accuracy.
• It occupies narrower aisles and travels along a single lane, typically requiring multiple units to cover the entire warehouse area.

• With a standardized design, its overall cost is lower than multi-mast systems. A single crane can cover the entire warehouse area, offering higher economic efficiency.
• It automatically performs inbound, storage, and outbound tasks without human intervention.

Warehouse Stacker Crane Parameters

The stacker crane adopts a box-type girder structure. The single-mast lifting height ranges from 5–30 m. The maximum load capacity is 2T for single-deep storage and 1T for double-deep storage. Anti-sway control is standard across all models, enabling intelligent automatic location searching.

• Horizontal travel speed: 180 m/min
• Cargo platform speed: 60 m/min
• Fork speed: 60 m/min
• Acceleration: 0.5 m/s²

Key Features & Advantages

• Three-dimensional automatic operation for higher efficiency: X/Y/Z coordinated movement optimizes cycle time and significantly shortens inbound and outbound processes.
• High positioning accuracy for dense storage: Telescopic forks support single-deep, double-deep, and multi-deep cargo access.
• Simple structure, stable performance: Independently developed by KUANGSHAN CRANE, with strong rigidity and easy maintenance, suitable for long-term high-frequency operation.
• High automation with system integration: Compatible with WMS, WCS, and other systems for automatic task scheduling, slot management, and intelligent dispatching.
• Fully unmanned workflow: Inbound, storage, and outbound operations can be completed without manual intervention, improving efficiency while reducing labor costs.

Application Scenarios

• Automated high-bay warehouses for large manufacturing enterprises
• Heavy-duty or palletized material storage systems
• Logistics and distribution centers
• In-plant intelligent logistics for smart factories
• High-density, multi-level racking warehouses

Intelligent Warehouse Stacker Crane Workflow Cases

Inbound Process: A forklift places materials at the designated inbound point. The intelligent stacker crane receives the system command, travels quickly to the inbound point, uses the lifting fork to pick up the material accurately, rotates the trolley's slewing mechanism to align the fork with the material orientation, and—based on warehouse system planning—stores the material in the appropriate empty rack position. The system also records the outbound code for fast retrieval.

Outbound Process: Based on the outbound code, the system assigns the intelligent stacker crane to the rack where the material is stored. The crane travels to the corresponding row and column, accurately picks up the material, and removes it from the rack. The trolley then rotates under the slewing gear to safely adjust the material orientation, transports it through the safety channel, and places it at the fixed outbound point, where a forklift completes the transfer.

The intelligent warehouse stacker crane developed by KUANGSHAN CRANE is now in mass production and operational. With a simple structure, stable performance, easy operation, and precise automation, it is the ideal solution for large, high-density automated warehouses.
