Storing long, heavy bars and tubes has always posed unique challenges: they’re cumbersome, prone to rolling, difficult to access when stacked, and hazardous if improperly handled. Enter Crank-Out Cantilever Racks—a purpose-built shelving system that transforms chaos into order, danger into safety, and inefficiency into streamlined workflow.

How It Works: Simplicity Meets Strength

At the heart of the system is a manual crank mechanism connected to a series of interlinked arms. Turning the crank engages a gear-driven rail system, smoothly extending the selected shelf layer outward. Thanks to high-precision ball bearings, even a fully loaded arm (up to 5,000 kg) glides with minimal effort—operable by a single person.

Once extended, the entire arm is exposed, allowing cranes or hoists to lift materials directly. No more digging through stacks or repositioning bundles. This direct-access design slashes handling time and eliminates the “first-in, last-out” problem common in bulk stacking.

Tailored for Bars, Tubes, and Beyond

While ideal for steel pipes and hollow sections, the system excels with solid bars, rebar, aluminum extrusions, and even lumber. Adjustable arm lengths (550–800mm) and inter-layer spacing (600–800mm) accommodate varying diameters and bundling methods. Optional U-shaped arm tips or rubber-lined supports prevent surface damage on polished or coated products.

For facilities managing mixed inventories, the ability to store by category or size is invaluable. One rack can hold multiple SKUs without cross-contamination or misplacement. Leftover cut-offs? Store them in dedicated remnant trays mounted on unused arms—keeping waste organized and reusable.

Safety and Ergonomics: A Non-Negotiable Priority

Manual handling of long materials is a leading cause of workplace injuries—strains, crushes, falls. The Crank-Out system dramatically reduces these risks by eliminating unsafe stacking and minimizing physical exertion. Workers no longer need to climb, lift, or balance heavy bundles. Instead, they operate a crank from a stable, ergonomic position.

The manual interlock ensures only one layer extends at a time, preventing accidental collapse. Meanwhile, the low-profile base frame avoids trip hazards, and the powder-coated finish resists chipping and corrosion—even in humid or outdoor environments.

Space Intelligence: Doing More with Less

Traditional bar storage often consumes vast floor areas with low-density stacking. Crank-Out Cantilever Racks flip this model vertically. With up to 8 levels and heights reaching 20 feet, they unlock unused airspace. Because crane handling replaces forklift access, aisles can be as narrow as 2.5 meters, freeing up space for production or additional storage.

A standard double-sided 4+1 layer unit (4 main layers + base) can hold 19–21 tons—enough for hundreds of pipe bundles. And because the system is modular, you can expand horizontally or vertically as your business grows.

Why Industry Leaders Choose Crank-Out Systems

From automotive suppliers to utility contractors, companies report 30–50% faster material retrieval, reduced damage claims, and lower insurance premiums after switching to Crank-Out Cantilever Racks. The initial investment pays for itself within 12–18 months through labor savings and space optimization.

Moreover, the system aligns with lean manufacturing principles: visual management, standardized work, and continuous flow. Every item has a designated place, visible and reachable—key tenets of 5S methodology.

In essence, Crank-Out Cantilever Racks are more than shelving—they’re a workflow enabler. They turn a logistical bottleneck into a competitive advantage, proving that sometimes, the simplest mechanical solutions deliver the greatest returns.
