The Four Way Shuttle System is an automated pallet storage solution that combines intelligent shuttle vehicles, vertical lifts, warehouse racking, conveyors, and WMS/WCS software into one integrated system.
Unlike traditional AS/RS, four-way shuttles can travel both longitudinally and laterally on each storage level, providing greater flexibility, higher storage density, and scalable throughput. Whether for new warehouse construction or existing facility upgrades, the system can be customized to meet different storage capacities and operational requirements.
| Project Items | Zhuku Four-Way Shuttle | Why It Matters |
| Shuttle Height | 125 mm | Ultra-thin design helps maximize vertical storage space and increase the number of usable storage levels. |
| Load Capacity | 1500+ kg | Supports heavy-duty pallet handling for manufacturing, automotive, food, beverage and other industrial applications. |
| Max. No-load speed | 2 m/s | High travel speed supports faster pallet movement and improved warehouse throughput. |
| Max. Full-load speed | 1.2 m/s | Maintains efficient pallet transportation during loaded operations. |
| Direction Change Time | 2.5 s | Rapid longitudinal/lateral direction changes improve shuttle flexibility and operational efficiency. |
| Operating Temperature | -25°C to 45°C | Suitable for cold storage, frozen food and temperature-sensitive warehouse environments. |
| Positioning Accuracy | ±1 mm | Enables precise pallet positioning within high-density racking systems. |
| Driving Accuracy | ≤2 mm | Precise and stable shuttle movement |
Note: Technical specifications can be customized according to project requirements
A complete Four-Way Pallet Shuttle System consists of:
| Component | Function |
| Four-Way Shuttle | Automatically transports pallets in four directions within storage aisles. |
| Vertical Lift | Transfers shuttle vehicles and pallets between storage levels. |
| High-Density Racking | Provides compact pallet storage with maximum space utilization. |
| Conveyor System | Automatically transports pallets to and from storage locations. |
| Warehouse Control System (YUNTU-WCS) | Coordinates all automation equipment, manages task scheduling, and optimizes traffic flow. |
| Warehouse Management System (CC-WMS) | Manages inventory, warehouse operations, and business data while connecting with ERP and MES systems. |
The operation begins when pallets enter the warehouse through the receiving conveyor. The Warehouse Management System automatically assigns the optimal storage location based on inventory strategy, product characteristics, and warehouse capacity.
Vertical lifts transport the shuttle vehicle and pallet to the designated storage level. The four-way shuttle then travels both longitudinally and laterally to place the pallet in its assigned position. During outbound operations, multiple shuttle vehicles work simultaneously under intelligent scheduling, retrieving pallets efficiently according to FIFO, LIFO, or customized warehouse rules.
This collaborative operation significantly improves warehouse throughput while reducing manual intervention and operational costs.
High-Density StorageThe four way pallet shuttle system enables compact storage layouts with fewer aisles, increasing storage capacity by up to 200% compared with conventional pallet racking while maximizing warehouse space utilization. |
Intelligent Multi-Shuttle SchedulingPowered by the self-developed YUNTU-WCS Warehouse Control System, multiple shuttle vehicles, lifts, and conveyors operate collaboratively through intelligent task allocation and route optimization, ensuring efficient and balanced warehouse operations. |
Flexible and Scalable DesignThe modular system architecture allows additional shuttle vehicles, lifts, storage aisles, or software modules to be added without interrupting existing operations, supporting future warehouse expansion. |
Ultra-Thin Shuttle DesignWith a shuttle height of only 125 mm, the system minimizes rack beam height requirements and creates additional storage positions, allowing higher warehouse utilization without increasing building dimensions. |
Cold Storage ReadyDesigned for demanding environments, the 4D shuttle system operates reliably in temperatures ranging from -25°C to +45°C, making it suitable for frozen food, pharmaceuticals, fresh produce, and other temperature-controlled applications. |
24/7 Continuous OperationAutomatic charging, intelligent task scheduling, remote diagnostics, and predictive monitoring enable uninterrupted warehouse operations with minimal manual intervention. |
Seamless Software IntegrationThe system integrates with ERP, MES, SAP, Oracle, and other enterprise management platforms through standard communication interfaces. Proprietary CC-WMS and YUNTU-WCS provide complete inventory visibility, equipment coordination, and intelligent warehouse management. |
Enhanced Safety & Stable OperationThe automated pallet shuttle system reduces forklift traffic inside storage aisles while providing real-time equipment monitoring, position detection, and fault alerts. These features improve operational safety and help maintain reliable, stable warehouse performance. |
