What is a cantilever rack storage system?

A cantilever rack storage system refers to the entire storage area or storage concept in which long goods are stored on so-called cantilever racks. These racks consist of vertical columns to which horizontally projecting arms are attached. The stored goods – typically pipes, rods, profiles, panels, square timber, or sheet metal bundles – rest freely on these arms without being restricted by side walls or cross braces. This allows goods of various lengths to be stored flexibly and retrieved from the front or side.

The cantilever rack storage system differs from the individual cantilever rack as a higher-level concept: it encompasses the entirety of the racking system, traffic routes, handling equipment, safety devices, and organizational processes that together constitute a functional storage area for long goods.

How does a cantilever rack storage system work in practice?

Cantilever racks can be designed for single-sided or double-sided access. Single-sided versions are suitable for wall placement and confined spaces, while double-sided structures enable denser use of floor space within the building interior. Depending on the operation, handling is carried out using forklifts, sideloaders, overhead cranes, or specialized long goods conveyors. The choice of handling equipment directly influences the required aisle widths and thus the floor layout planning.

The arms are usually height-adjustable, so the spacing can be adapted to different load cross-sections and bundle sizes. Load capacity per arm and per column are key technical parameters that must be designed to accommodate the actual weight of the heaviest stored goods during planning. For heavy metal parts, galvanized or coated steel structures are frequently used, while lighter goods such as wooden panels can also be stored on lightweight racking systems.

In terms of safety, cantilever rack storage systems are subject to particular requirements: lifting equipment, fall protection at open rack aisles, and the structural stability of racks against vehicle impacts must be inspected and documented. In many operations, regular rack inspections by qualified personnel are required, although the precise statutory requirements may vary depending on national regulations.

What factors matter when making a selection?

When planning a cantilever rack storage system, you should consider the following aspects:

• Stored goods: Lengths, weights, cross-sections, and bundle sizes determine arm spacing, load capacity, and rack depth.
• Handling equipment: Forklifts, sideloaders, or cranes require different aisle widths and building heights.
• Accessibility: Single-sided or double-sided operation influences area efficiency.
• Surface protection: Corrosion protection is a relevant selection criterion for metallic goods or humid environments.
• Safety and inspection obligations: Rack inspections, impact protection, and occupational safety requirements must be factored in from the outset.

Whether a stationary or mobile cantilever rack storage system makes sense depends on throughput and the variety of stored goods. Mobile cantilever racks on rails can improve space utilization for manageable product ranges, but require a higher capital investment.
