Stacker AS/RS Builds a New Cornerstone for Power Material Support

A provincial power company responsible for regional grid operation, maintenance and emergency repair, with over 10,000 types of equipment including transformers, cables and insulators, requiring efficient intelligent warehousing to support safe and stable grid operation.


Stacker AS/RS Builds a New Cornerstone for Power Material Support
Project Value
  • Support Upgrade: Emergency material response time shortened from 4 hours to 30 minutes, greatly improving grid operation efficiency

  • Lean Management: Inventory discrepancy rate reduced to <0.1%, with transparent and traceable full lifecycle material control

  • Cost Optimization: Labor costs cut by 70%, space utilization increased by 183%, saving over 6 million yuan annually


Project Background

Traditional flat warehouses had <30% space utilization, low manual sorting efficiency, slow response to emergency materials, and high inventory discrepancy rates, failing to meet the grid's lean management and emergency support needs.

Solution
  • Built a stacker AS/RS with 35,000+ positions, boosting space utilization to 85%

  • Stackers + conveyors enabled fully automated access, sorting and inventory for power materials

  • WMS linked with stackers for batch traceability, dynamic inventory control and priority scheduling for emergency repairs


Project Difficulties
  • Large variations in power material specifications, from precision instruments to heavy equipment, requiring stable and adaptive access for stackers

  • High response time requirements for emergency materials, needing optimized scheduling algorithms for priority outbound

  • Seamless integration with grid ERP and dispatch systems for real-time data synchronization
