Why Shuttle Systems Matter
As demands on modern warehousing increase, businesses are turning to automation to unlock space, improve throughput, and reduce reliance on manual labour. Among the most effective technologies in this shift are pallet shuttle systems, and at Allied-Storage & Racking, we specialise in designing and implementing advanced solutions built on trusted technologies like the Stow Atlas® shuttle system family.
Whether you’re optimising high-density storage or scaling up throughput, choosing the right type of shuttle system is critical. This guide explores the three primary categories of pallet shuttles—1D and 2 D—to help you identify the best match for your operational needs.
1D Pallet Shuttle Systems (Stow Atlas® 1D)
Foundational Automation for High-Density Storage
The Stow Atlas® 1D system is a semi-automated solution designed to streamline horizontal pallet movement in deep-lane storage environments. As a proven entry point into automation, it reduces forklift travel while maximizing racking density. Allied have installed in multiple locations including Atlantic Dawn.
Key Features:
- Single-Direction Movement: Travels forward and backward along storage lanes.
- Forklift Support Required: Operators place and retrieve the shuttle as needed.
- Battery-Powered Operation: Wireless control for efficient use.
- Cost-Effective Automation: Quick ROI in dense, low-SKU environments.
Ideal For:
- Businesses exploring first-phase automation
- Low SKU variability and FIFO/LIFO setups
- Cold storage and high-density bulk storage
2D Pallet Shuttle Systems (Stow Atlas® 2D)
Smart Automation with Movement along both longitudinal and transverse axes within all racking levels!
- The Stow Atlas® 2D system expands automation by enabling travel along both longitudinal and transverse axes within racking levels. Integrated with warehouse software, it provides fully automated pallet handling across an entire storage level.
Key Features:
- Two-Dimensional Navigation: Forward/back and side-to-side motion.
- Integrated Control: Works with WMS and WCS systems for real-time operations.
- Dynamic Slotting: Pallets are automatically stored and retrieved from optimal positions.
- Reduced Human Interaction: Less reliance on forklifts or manual input.
Ideal For:
- Medium-to-high throughput operations
- Moderate SKU complexity
- Facilities requiring greater space utilisation without full infrastructure change

| Throughput | Moderate | High | |
| Infrastructure Needs | Low | Medium (rails within levels) | |
| SKU Flexibility | Low | Moderate | |
| Ideal For | Cold storage, dense FIFO | General-purpose, flexible operations |
Frequently Asked Questions
How does the Stow Atlas® system integrate with warehouse software?
Both the 1D and 2D shuttle systems from Stow integrate seamlessly with WMS/WCS platforms via control software, enabling real-time command, inventory tracking, and system health monitoring.
Can I retrofit a Stow shuttle system into an existing warehouse?
Yes. Allied-Storage regularly retrofits Stow Atlas® systems into existing facilities with minimal disruption. We assess your current infrastructure and design systems that integrate cleanly without full structural overhauls.
How long is the ROI on shuttle systems?
Most operations achieve ROI in 2–4 years. The timeline depends on labour savings, storage density gains, and overall system utilization.
