Stacker Crane

A stacker crane is a key component of automated storage and retrieval systems (AS/RS), designed for high-density warehousing. It enables fast, precise, and reliable storage and retrieval of pallets or bins, maximizing vertical space utilization and operational efficiency.

Stacker Crane Functional Overview​​

  • ​​High-Density Warehouse Management​​: Execute vertical/horizontal transfers of pallets/material boxes within 10-40m shelving channels, achieving 3-5x higher space utilization than conventional warehouses.
  • ​​Production Line Integration​​: Synchronize with conveyor systems and AGVs in automotive/electronics manufacturing for automated raw material feeding and finished product storage.
  • ​​High-Throughput Order Fulfillment​​: Support “goods-to-person” picking in e-commerce/pharmaceutical sectors, delivering 80-150 cycles/hour (>5x manual efficiency).
  • Specialized Environment Operations​​: Low-temperature variants (-30℃) for cold chain logistics, explosion-proof models (ATEX-certified) for chemical storage, and cleanroom-compatible units for semiconductor manufacturing.

Core Technical Capabilities​​

  • Three-Dimensional Precision Positioning​​: Laser ranging + encoder positioning achieves ±1mm horizontal / ±2mm vertical accuracy with automatic shelf alignment compensation.
    ​​High-Speed Stability Control​​: Dual-mast stacker cranes reach 120m/min horizontal speed, 40m/min lifting speed, and 0.3m/s² acceleration while ensuring cargo stability.
  • Multi-Carrier Compatibility​​: Interchangeable tooling: clamp arms (cartons), telescopic forks (long loads), rotating grippers (material boxes), compatible with EUR/JIS pallets and custom carriers.
  • ​​Intrinsic Safety Mechanisms​​: Triple-layer protection: laser obstacle detection, mechanical limits, overload cutoff. Emergency descent system activates during power failure to prevent cargo suspension.

Competitive Differentiation​​

  • ​​Maximized Spatial Efficiency​​: Stacker cranes support 40m vertical storage systems, increasing density by 300% and reducing land costs by >50%.
  • ​​Uninterrupted Productivity​​: Dual-deep stacker cranes achieve ≤60s cycle times with circular rail systems enabling 24/7 operations (throughput capacity: 500 pallets/hour).
  • ​​AI-Powered Optimization​​: Machine learning algorithms reduce empty travel by 20%, integrated with WMS/WCS for real-time inventory control.
  • ​​Cross-Industry Versatility​​: Modular architecture supports load customization (50kg-5 tons), low-temperature (-30℃), explosion-proof, and MIL-SPEC configurations.
