In high-purity stainless steel distribution, a tipped bundle isn’t just a safety incident—it’s a financial disaster. When you are handling 20-foot lengths of polished 316L tubing or heavy solid bars, the “forklift and hope” method is a liability. Our Crank Out Storage Racks eliminate the instability of floor stacking and the risks of forklift maneuvering, anchoring your inventory securely while giving your overhead crane 100% access.
The Hidden Dangers in Storing Round Stock and Profiles
For Steel Service Centers and manufacturers like those specializing in hygienic stainless components, gravity is the enemy. Traditional static cantilevers require forklifts to navigate narrow aisles with wide loads. When an operator tries to extract a bundle of tubes from a middle shelf, they often have to shift the surrounding inventory.
This “secondary handling” is where accidents happen. Round bars roll. Polished tubes slide. A slight imbalance on a forklift tine can send thousands of pounds of metal crashing down. Furthermore, the sheer footprint of floor stacking forces operators to climb over piles, creating severe trip and crush hazards.
Engineering Out the Risk: How Crank Out Racks Work
The primary defense against tipping and load instability is the structural design of the storage system itself. Unlike standard racks where the load is static and hard to reach, Crank Out Storage Racks make the rack do the work, not the operator.
1. Controlled Extension Mechanism
The core of the system is the extendable arm. Using a high-reduction gear system (rack and pinion), a single operator can rotate a crank to extend a fully loaded level (up to 5 tons) out into the aisle. The movement is smooth, controlled, and linear. There is no jerking or swaying that could cause the load to shift or roll off.
Even fully loaded with heavy bar stock, the geared crank mechanism allows for smooth, single-person operation without physical strain.
2. The “Anti-Tip” Foundation
You cannot extend 3 tons of steel 100% out of a rack without a massive counter-force. Our racks utilize a heavy-duty H-beam base construction that is significantly wider and heavier than standard uprights.
Crucially, the installation process involves rigorous anchoring. We don’t just bolt them down; we chemically anchor the base to your concrete slab to withstand the immense moment arm created when the drawers are extended. This ensures the rack remains perfectly vertical and rigid, even during dynamic loading.
Proper anchoring to the concrete floor is critical for anti-tip safety when heavy drawers are fully extended.
Preserving Surface Integrity: The “No-Touch” Approach
In industries dealing with high-purity fittings and pharmaceutical-grade tubing (like GHWA), surface finish (Ra) is everything. A scratch from a forklift tine or a collision with another bundle renders the material scrap.
By using Draagarmstellingen, you switch from forklift retrieval to **overhead crane retrieval**.
1. **Extend the Drawer:** The material moves out into open space.
2. **Vertical Lift:** The overhead crane drops straps directly perpendicular to the load.
3. **Zero Friction:** The load is lifted straight up. No dragging, no sliding, no metal-on-metal contact.
This method is the only way to guarantee the integrity of polished stainless steel or aluminum profiles during storage and retrieval.
By utilizing overhead cranes, operators avoid the “forklift jousting” that leads to damaged inventory and tipping accidents.
Electric Options for High-Volume Centers
For Steel Service Centers processing hundreds of orders a day, manual cranking might be too slow. We offer motorized versions of our Crank Out Storage Racks.
With a handheld remote, the operator can stand at a safe distance and control the extension of specific levels. This further removes the human element from the “danger zone” and speeds up the cycle time from storage to the laser cutter or saw.
Electric push-button controls allow for precise positioning and keep operators at a safe distance during the extension cycle.

FAQ: Steel & Tube Storage Safety
1. Can these racks handle the weight of solid stainless steel bar stock?
Absolutely. This is exactly what they are designed for. Unlike light-duty shelving, our racks use structural steel components. A single level can carry up to 5 tons (11,000 lbs). We calculate the load based on your specific material density to ensure the anti-tip safety factor is met.
2. We use UHMW liners to protect our polished tubes. Can you accommodate this?
Yes. We can fit the cantilever arms with UHMW (Ultra High Molecular Weight Polyethylene) strips or other protective linings. This ensures your high-purity tubes rest on a soft, non-abrasive surface, preventing carbon contamination or scratching.
3. How much floor space can I actually save?
By eliminating the wide aisles required for forklifts to turn with 20-foot loads, you can typically reduce your storage footprint by 40% to 50%. You only need enough aisle width for a person to walk and operate the crank/remote, as the loading is done from above via crane.
4. Does the installation require special flooring?
Because of the high density and the moment forces involved when drawers are extended, a reinforced concrete slab is usually required. Our engineering team will review your facility’s floor specs (concrete thickness and PSI) to determine the anchoring requirements for maximum anti-tip safety.
5. Can we store short cut-offs and full lengths in the same rack?
Yes. We can install intermediate support beams or steel decking/trays across the cantilever arms. This creates a solid shelf that can hold shorter cut pieces, valve components, or fittings, keeping your inventory consolidated in one accessible unit.
