Long Span Shelving Selection Guide: Manual vs. Automated Racking Systems

When designing long span shelving systems, the choice between manual and automated racking is a critical strategic decision. This comprehensive guide explores the key differences, advantages, and disadvantages of each approach, providing a framework to help optimize warehouse operations.

Everunion, with over 20 years of experience in logistics equipment, offers long span shelving solutions engineered to support both manual operations and advanced automated integrations .

Introduction

Long span shelving systems are essential for warehouses and logistics facilities to efficiently manage a wide range of materials. The decision between manual and automated racking systems significantly impacts operational efficiency, storage capacity, and overall cost-effectiveness. Understanding the core capabilities and limitations of each system is the first step toward making a sound capital investment.

Everunion manufactures three primary categories of long span shelving :

Manual Racking Long Span Systems

Definition and Explanation

Manual long span shelving systems rely on human labor, typically utilizing forklifts or hand-picking, to move goods within the warehouse. These systems are simpler in design and require less upfront investment compared to automated solutions .

Ideal applications include:

• Smaller warehouses with lower inventory turnover rates

• Facilities with highly variable SKU dimensions

• Operations that prefer a hands-on approach to inventory management

• Hand-loaded picking areas where forklift access is unnecessary

Advantages and Disadvantages

Advantages:

• Cost-Effective: Manual systems have significantly lower initial costs due to the absence of complex machinery, robotics, and software integration

• Flexibility: Manual racking can adapt quickly to changes in inventory dimensions without requiring software reprogramming 

• Ease of Use: As the least complex system to operate, it requires minimal specialized training for warehouse staff

• Proven Reliability: Simple mechanical connections mean fewer points of failure

Disadvantages:

• Lower Efficiency: Manual racking is inherently slower due to the physical limitations of human labor and forklift travel times

• Potential for Human Error: Higher likelihood of picking mistakes, placement errors, and safety incidents due to fatigue or inexperience

• Limited Vertical Utilization: Long span shelving cannot match the height of high-bay systems 

• Labor Dependency: Operational capacity is directly tied to staffing levels

Load Capacity Details

Manual long span shelving by Everunion is highly versatile and categorized by load-bearing capabilities :

• Light Duty: Up to 500 lbs per level – suitable for light industrial environments, office supplies, and electronics

• Medium Duty: 1,000 to 5,000 lbs per level – ideal for semi-finished goods, industrial supplies, and retail merchandise

• Heavy Duty: Up to 10,000 lbs per level – designed for heavy objects such as machinery parts and raw materials

Automated Racking Long Span Systems

Definition and Explanation

Automated racking systems leverage advanced technology—such as AS/RS (Automated Storage and Retrieval Systems), vertical lift modules, and shuttle carts—to move goods within the warehouse, drastically reducing the need for manual labor . Everunion offers several automated solutions including radio shuttle racking, pallet-type AS/RS, and bin-type AS/RS .

These systems are more complex and require higher initial investment but offer significant benefits in efficiency, density, and accuracy.

The evolution from basic to automated racking represents a fundamental shift in warehouse operations. Semi-automated solutions integrating forklifts and conveyors emerged before giving way to fully automated AS/RS technology .

Advantages and Disadvantages

Advantages:

• Increased Efficiency: Automated systems retrieve and store goods much faster than manual systems, operating continuously without fatigue 

• Reduced Error Rates: Automation minimizes human error through software-directed put-away and picking protocols, achieving accuracy rates above 99.5%

• Superior Space Utilization: Vertical storage capacity can be increased by up to 50% compared to traditional static shelving 

• Scalability: Throughput can be increased by adding more automated devices without expanding the building footprint 

Disadvantages:

• Higher Initial Costs: Substantial upfront capital required for equipment, software, and integration

• Complexity: More difficult to engineer, install, and operate, requiring specialized IT and maintenance personnel

• Maintenance Requirements: Regular, specialized preventative maintenance is required; downtime can be highly disruptive

• Longer Implementation Timeline: From assessment to commissioning requires careful planning

Cost Comparison: Total Cost of Ownership (TCO)

While automated systems require greater upfront investment, facilities report significant long-term savings through reduced labor costs, improved accuracy, and higher throughput .

Efficiency and Productivity Comparison

How Automated Racking Improves Efficiency

Faster Picking and Retrieval

Automated systems can retrieve items in seconds, significantly reducing pick times compared to operators traveling aisles on forklifts. Accuracy is enhanced through strict adherence to barcode verification protocols .

Increased Throughput

Automated systems handle much higher throughput rates, allowing businesses to manage larger volumes of goods during peak seasons without relying on temporary labor.

Better Inventory Management

AS/RS systems integrate with Warehouse Management Systems (WMS) to provide real-time data on inventory levels, making it easier to track stock and prevent shrinkage . Automated systems support functions like cycle counting, dynamic put-away, and order release. WMS integration provides real-time visibility into stock levels and locations .

Enhanced Safety

Automated systems equipped with sensors and access controls reduce risks associated with manual lifting, forklift traffic, and human error .

Selection Framework: Manual vs. Automated

Choose Manual Racking When:

• Lower throughput volumes – Daily picks do not justify automation investment

• High SKU variability – Inventory dimensions change frequently

• Limited capital budget – Lower initial investment required

• Flexible labor pool – Staff availability is not a constraint

• Shorter planning horizon – Less commitment to fixed infrastructure

Choose Automated Racking When:

• High throughput volumes – Fast-moving inventory requiring rapid retrieval

• Consistent SKU profiles – Inventory dimensions are predictable

• Labor cost pressures – Reducing dependence on manual labor is a priority

• Space constraints exist – Maximum vertical density is required

• Long-term growth planned – Scalability is a key requirement

• Integration with WMS – Real-time inventory visibility is critical
