4 Way Shuttle System

The Four-Way Shuttle System is a high-density automated storage solution designed for efficient palletized goods management. It is ideal for industries with a limited number of SKUs (Stock Keeping Units) and operations that require storage and retrieval by lot or batch. This system is particularly suitable for sectors such as food & beverage, chemicals, and logistics services, enhancing space utilization and operational efficiency.

How the 4 Way Shuttle System Works

This system utilizes advanced movement technology, allowing pallets to travel in four directions: left-right, front-back, and up-down. This flexibility enables optimized routing within the storage area, maximizing horizontal space utilization. Compared to traditional Automated Storage and Retrieval Systems (ASRS), the Four-Way Shuttle System increases storage density by approximately 5-10%, making it a highly efficient solution for high-density warehousing.

Benefits of 4 Way Shuttle System

Maximized Storage Capacity

The system increases storage capacity by making the most of the available warehouse space and height, even in limited areas.

Future Expansion Ready

Easily extend racking and storage tracks in the future without disrupting system operations during installation.

Seamless WMS/WCS Integration

The system fully integrates with WMS or WCS , ensuring smooth operation. It supports wireless connectivity for real-time, seamless control and monitoring.

Main Machine Broken Down

Shuttle carts can operate independently. If one unit fails, others can take over its function. Additionally, they have a backup power system to help reduce downtime.

Comparison Between

Stacker Crane and 4 way Shuttle Systems

Functionality

Stacker Crane

4 Way Shuttle

Space Management

Stacker Crane

  • Utilizes vertical space efficiently, with a maximum height of 40 meters.
  • Suitable for warehouses that require both horizontal and vertical storage.

4 Way Shuttle

  • Optimized for horizontal space utilization with a height limit of 15 meters.
  • Can increase storage density by 5-10% more than ASRS.

Throughput (Storage & Retrieval Rate)

Stacker Crane

  • High throughput depends on the number of stackers in the system.

4 Way Shuttle

  • Suitable for medium throughput levels with autonomous shuttle operations.

Storage Flexibility

Stacker Crane

  • Can directly access any rack position using vertical rails.

4 Way Shuttle

  • Four-way shuttle system moves in four directions: left-right, front-back, and up down.
  • Allows flexible storage position adjustments based on warehouse design.

Storage Strategy

Stacker Crane

  • Suitable for warehouses with diverse SKUs.
  • Supports multiple storage strategies such as FIFO, FEFO, LIFO, LEFO, Hold, By Order, By Location, By SKU, By Lot, and By Batch.

4 Way Shuttle

  • Best for warehouses with fewer SKUs.
  • Supports By Lot and By Batch strategies, commonly used in food, beverage, and chemical industries.

Scalability

Stacker Crane

  • Can expand vertically by adding more stackers.
  • Requires modifications to the system for expansion.

4 Way Shuttle

  • Can easily expand horizontally by adding more shuttle carts without stopping operations.
  • Supports modular expansion without major structural changes.

Operating Temperature

Stacker Crane

  • Operates in a temperature range of -25°C to 40°C.

4 Way Shuttle

  • Operates in a temperature range of -25°C to 40°C.

Maintenance Requirements

Stacker Crane

  • Requires minimal maintenance.
  • Regular inspections of rails and sensors are needed.

4 Way Shuttle

  • Shuttle carts require more frequent maintenance than stackers.
  • Uses battery-powered shuttles that need periodic charging.

Machine Breakdown

Stacker Crane

  • If a stacker fails, a backup stacker is required to continue operations.
  • Downtime occurs when replacing stackers.

4 Way Shuttle

  • If a shuttle cart fails, other shuttles can continue operations without interruption.
  • Backup power reduces system downtime.

System Installation

Stacker Crane

  • Requires a longer installation time due to rail and stacker setup.
  • May need structural modifications for high-bay storage.

4 Way Shuttle

  • Faster and easier installation than stacker crane systems.
  • Can expand storage without stopping operations.
