4-Way Shuttle Smart Warehouse System
The 4-Way Shuttle Smart Warehouse System is an automated storage solution that utilizes autonomous shuttle vehicles (AGVs) capable of flexible movement in four directions—forward, backward, left, and right—on the same rack level.
The system operates in compliance with multiple storage strategies, including Selective, FIFO (First In, First Out), and FILO (First In, Last Out).
The entire operation process is fully automated through the coordination between AGV shuttles and the WMS (Warehouse Management System). In this system, the AGV shuttle is responsible for horizontally transporting goods to the lifter (elevator) position. The lifter then receives the load and moves it up or down between storage levels as required by the system. Operators only need to input data via the HMI, while all remaining processes are handled automatically.
ADVANTAGES
- Space optimization: Compared to stacker crane solutions, this system eliminates the need for vehicle aisles, maximizing floor space utilization.
- Flexible scalability: The modular design allows businesses to easily expand storage capacity as demand grows, without interrupting ongoing operations.
- Stable and safe operation: Equipped with sensors, safety fences, and protection systems to ensure continuous monitoring and minimize workplace accident risks.
- High accuracy: Fully automated inbound and outbound processes ensure low error rates, improving reliability in inventory management.
- Enhanced efficiency: Processing speed reaches 5–10 pallets/hour, reducing waiting time for inbound and outbound operations. The system supports multiple picking strategies, with Selective as the primary mode, combined flexibly with FILO and FIFO according to requirements.
- Suitable for multiple storage environments: Designed to operate reliably in harsh conditions, with a working temperature range from -5°C to +40°C.
SYSTEM STRUCTURE
AGV 4-Way Shuttle
The AGV 4-way shuttle can move in all directions—forward, backward, left, and right—to access any position on a single storage level. This enables automated handling, transportation, storage, and retrieval of goods based on commands from the software system.
When combined with a layer-changing elevator, the 4-way shuttle can operate throughout the entire warehouse space without being limited to a single level.
Layer-Changing Elevator (Lifter)
The layer-changing elevator is a core component of the automated warehouse system, responsible for transporting goods to designated levels after receiving them from the 4-way shuttle. Featuring a robust aluminum frame, energy-saving counterweight mechanism, and fully automatic control, the lifter ensures fast, accurate, and stable vertical movement.
