Addressing Space Constraints in Warehousing with High-Density Storage Solutions
Guest blog from MHI Member Company HUBMASTER Warehouse Automation Systems
With ever-increasing demands for storage, many warehouses are reaching capacity limits within their existing footprints. Expanding or relocating can be cost-prohibitive and disruptive, pushing facilities to explore ways to maximize available space without increasing square footage. Effectively using every inch of a warehouse has become essential as businesses strive to maintain efficiency and meet growing demands. A lot of warehouse personnel is seeking ways that they can convert their brownfield warehouse to have it to be more efficient and more densified.
High-density storage solutions provide a practical and scalable answer to these spatial challenges. By focusing on vertical storage, Very Narrow Aisle (VNA) configurations, and multiple deep configurations in racking systems, warehouses can significantly enhance their storage capacity without the need for physical expansion. This approach enables companies to store more goods in the same space while keeping operations organized and accessible.
The Impact of Space Constraints in Warehousing
Space constraints in a warehouse setting lead to various challenges, including slower retrieval times, increased picking errors, and, in some cases, even safety hazards due to overcrowded or cluttered aisles. Inefficiencies in space utilization can escalate operational costs and complicate the workflow, as workers spend more time maneuvering through congested areas or searching for items. This inefficiency not only affects the warehouse’s bottom line but also impacts the entire supply chain, resulting in delays in order fulfillment and compromised customer satisfaction.
As warehouses continue to face higher storage demands—driven in part by the growth of e-commerce and the rising expectation for fast deliveries—the ability to maximize storage without expansion is more important than ever. The COVID-19 pandemic further highlighted these issues, as disruptions in supply chains and shifts toward increased inventory levels created an unprecedented demand for efficient storage solutions, intensifying the need to maximize existing warehouse space.
High-density storage systems allow warehouses to achieve these goals by improving the efficiency of their current space.
Key Components of High-Density Storage
High-density storage includes several design and configuration strategies aimed at optimizing available space while keeping the layout functional and accessible.
- • Vertical Storage: Many warehouses underutilize vertical space, focusing primarily on floor-level storage. Vertical storage allows facilities to make use of their full height, stacking goods safely from floor to ceiling.
- • Very Narrow Aisle (VNA) Configurations: In traditional warehouse setups, aisle widths are designed for wider forklifts, which wastes valuable space. VNA configurations reduce aisle width, allowing for more storage racks within the same footprint. Specialized equipment operates effectively within these narrow spaces, increasing overall storage density. Aisles can be as little as 6 ft in order to operate, all while without touching the floor while doing working.
- • Multiple Deep Configuration in Racking: Multiple deep racking configurations, such as double-deep and push-back racking, enable the storage of two or more pallets in a single row, back-to-back, maximizing depth while minimizing aisle requirements. Double-deep racking allows pallets to be stored two-deep, reducing the number of aisles needed and improving capacity. Push-back racking systems add further efficiency by enabling loading and unloading of pallets on a slight incline, making it easier to access inventory without moving the pallets in front. These configurations increase storage density significantly and are ideal for facilities handling high-turnover or similar items that don’t require immediate access to every individual pallet.
Enhancing Efficiency with Automation
In high-density storage, automated systems play a crucial role. Technologies like Automated Storage and Retrieval Systems (ASRS) offer a reliable way to optimize space, improve retrieval speed, and enhance inventory accuracy. ASRS solutions are often integrated into VNA and multiple deep configurations, enabling automated cranes to navigate narrow and deep spaces efficiently, eliminating much of the manual handling typically required in traditional setups.
ASRS solutions can support multiple deep storage and VNA configurations. These systems are specifically designed to allow automated stacker cranes to retrieve pallets from double-deep or push-back racks, as well as within narrow aisle configurations, maximizing space and minimizing the need for human intervention. Facilities that implement such systems often experience improvements in order accuracy and retrieval speed while reducing the need for excessive labor.
Cost Benefits and Operational Efficiency of High-Density Storage
Implementing high-density storage solutions also translates into considerable cost savings. By maximizing existing space, facilities can avoid the high costs associated with physical expansion or relocation. The more effectively a warehouse utilizes its space, the less it will need to invest in additional real estate, freeing up capital for other operational improvements.
High-density storage also offers benefits in labor efficiency. Automated systems allow facilities to streamline operations by reducing the need for manual picking, retrieving, and restocking. These automated solutions can work continuously, decreasing downtime and improving productivity, even with a leaner workforce. The added efficiency means faster cycle times, more accurate order fulfillment, and, ultimately, a better experience for end customers.
