7 Ways Shuttle Storage Systems Improve Order Picking

As consumer demands and pressure on the e-commerce and supply chain continue to grow, businesses are seeking ways to integrate efficient and cost-effective warehouse automation solutions. One such technology to support operations and achieve maximum efficiency is shuttle storage systems, which significantly enhance order-picking accuracy and operational efficiency. These systems offer an ideal solution for many distribution centres looking to improve their picking process.

There are several types of shuttle storage systems available, such as Multi-Level Shuttles, Goods-to-Person and Pallet Shuttle systems, designed for specific product type handling requirements yet adaptable so each can be tailored to precise operational needs. They are also extremely versatile, able to integrate seamlessly with other automation technologies, providing a full turnkey storage and order-picking solution. This allows for the efficient deployment of warehouse management software.

In our latest article, we'll explore shuttle storage systems, their types and benefits, their applications across various industries, and how they integrate with other automation technologies to create the optimal solution for warehouse efficiency.

What is a Shuttle Storage System?


A shuttle storage system is a form of advanced warehouse automation technology that uses autonomous or semi-autonomous shuttles to store and retrieve goods from racking structures. These systems are designed to optimise the use of the available storage space, improve the speed of order fulfilment, and reduce both the cost and reliance on manual labour. Shuttles typically operate on fixed rails within high-density racking structures, transporting goods between storage locations and pick stations, often in conjunction with conveyor belts and robotic systems.

Types of Shuttle Storage Systems

Single-Level Shuttle Systems

These systems use shuttles that operate at one level at a time. They are ideal for high-throughput operations and can be expanded with multiple shuttles.

Multi-Level Shuttle Systems

Equipped with lifts and multiple shuttles, these systems handle goods at various levels within the racking structure, improving efficiency in high-density storage environments.

Pallet Shuttle Systems

Designed for heavy-duty palletised goods, these systems transport entire pallets to and from deep-lane storage or multiple-deep storage, which optimises bulk storage.

Bin/Tote Shuttle Systems

These shuttle systems are extremely efficient and ideal for e-commerce and small-item order fulfilment where the shuttles are needed to move bins and totes to the pick stations quickly.

Goods-to-Person (G2P) Shuttle Systems

G2P systems use shuttles, other automation technology such as conveyors or more widely, Autonomous Mobile Robots to bring stored individual items directly to workers at ergonomic picking stations, reducing travel time and increasing picking accuracy.

Increased Order Picking Speed

Shuttle systems drastically reduce the time required to locate and retrieve items. By automating the retrieval of goods from the racking, they eliminate unnecessary travel time for workers and ensure that products reach picking stations far more quickly. This speed is needed to achieve reduced order fulfilment times and support pressured delivery requirements that enhance customer satisfaction. This contributes significantly to cost savings by reducing operation time.

Enhanced Accuracy and Reduced Errors

Errors in manual picking can lead to incorrect shipments and costly returns. Shuttle systems use advanced tools such as barcode scanning and warehouse management software (WMS) integration to ensure the correct item is always picked, leading to near-perfect order accuracy.

Optimised Space Utilisation

Traditional methods for storage and order-picking require space such as wide aisles for forklifts to safely move to collect and replenish goods. Shuttle systems, however, utilise compact storage systems and high-density storage by operating in compact spaces, maximising both vertical and horizontal storage capacity within the available footprint of the actual warehouse, without compromising accessibility. This improved storage density is a key benefit.

Labour Cost Reduction

Manual picking requires significant manpower and is physically demanding and repetitive. By automating the retrieval process, shuttle storage systems reduce the dependency on a large workforce, leading to lower labour costs and potential for injury, while allowing employees to focus on higher-value tasks such as quality control and customer service. Integrating advanced technology also provides an opportunity for staff to learn new skills to programme, operate and maintain the shuttle systems.

Seamless Scalability

As businesses grow, so does the demand for efficient storage. Shuttle systems can be easily scaled by adding additional shuttles and pick stations, or expanding the racking systems, ensuring they accommodate increasing order volumes quickly and efficiently, without major changes to the existing infrastructure.

Improved Throughput and Productivity

Multi-shuttle systems can operate simultaneously at different levels, drastically increasing order throughput. They also facilitate continuous picking and replenishment, reducing the potential for bottlenecks and boosting overall warehouse productivity.

Enhanced Inventory Management and Real-Time Tracking

Shuttle systems are integrated with advanced WMS software (often with integrated Artificial Intelligence) that provides real-time visibility of stock levels. This reduces the risk of stockouts, prevents costly and inefficient overstocking, and enables accurate demand forecasting which ultimately optimises inventory control. This is a crucial element of efficient picking.

Industry Applications of Shuttle Storage Systems


Retail & E-Commerce

Retail & E-Commerce efficiently handles fast-moving SKUs, seasonal inventory, and high-order volume fulfilment. Ideal for clothing, electronics, home goods, and personal care products such as cosmetics and health & wellbeing items, shuttle storage systems optimise storage and retrieval.

Food & Beverage

Food & Beverage is perfectly suited to managing cold storage, frozen food, dairy, and packaged goods, ensuring the rapid retrieval of goods while maintaining optimal storage conditions and product integrity.

Pharmaceuticals

Pharmaceuticals must adhere to strict regulations, requiring secure, accurate, and timely access to medications, medical devices, and laboratory supplies, where precise order picking, as well as tracking and traceability, are essential.

Automotive & Manufacturing

Automotive & Manufacturing is ideal for storing and retrieving spare parts, tools, and components for just-in-time production, reducing downtime and improving the speed and efficiency of the overall supply chain.

Integration with Other Automation Technologies

Shuttle storage systems are not always used as standalone solutions; they have the ability to integrate seamlessly with other automation technologies providing efficient, fully automated, end-to-end warehouse optimisation. Here are some of the key technologies often integrated with shuttle systems, to great effect:

 

Robotic Picking Systems: Robots such as robotic picking arms are used to retrieve items from shuttle-delivered bins, further reducing the need for costly manual handling. These are examples of automated picking solutions and automated picking systems.

 

Automated Guided Vehicles (AGVs) & Autonomous Mobile Robots (AMRs): AGVs and AMRs transport goods between storage, sorting, and packing stations, with no human interaction. Both systems use advanced sensors and technology to enable safe and efficient movement of goods around the warehouse facility. 

 

Conveyor Systems: Streamlining the movement of items to and from shuttle systems for fast processing, conveyor systems offer a robust and reliable method of material flow. Modular in design, they can scale easily to support growth and requirements for handling new products. Consider the use of a pallet conveyor for automated storage and automatic storage systems. 

 

Warehouse Management Systems (WMS): Advanced software with integrated AI and machine learning provides real-time inventory visibility, tracking, and system control. This not only ensures efficiency across order fulfilment tasks, but it also provides vital data needed for strategic decision-making.

Conclusion

Shuttle storage systems offer a robust and versatile solution to revolutionise order-picking operations, increasing efficiency, accuracy, and scalability while reducing labour costs and maximising space utilisation. 

 

As all industry sectors look to automation for long-term efficiency gains, investing in shuttle storage technology is a strategic move toward improved productivity and enhanced supply chain resilience. And by integrating shuttle storage with other advanced technologies such as robotics, conveyor systems, or AMRs, businesses can achieve high-performance warehouse operations that will support and enhance their continued growth.
