In a maintenance shop, downtime is the enemy. When a critical conveyor shaft breaks or a structural support needs immediate replacement, you cannot afford to spend 20 minutes digging through a pile of mixed steel to find the right stock. Our quick-access roll out cantilever systems transform your raw material storage from a chaotic “boneyard” into a precision vending machine for heavy steel, allowing you to pull stock in under 2 minutes using your existing overhead crane.
The “Buried Stock” Problem in MRO Operations
Unlike production manufacturing where you run thousands of identical parts, a maintenance and repair operation (MRO) deals with high-mix, low-volume reality. You might need a 2-inch solid round bar today and a 4×4 angle iron tomorrow.
In traditional setups—whether it’s floor stacking or static cantilever racking—the piece of material you need is inevitably at the bottom of the stack or buried behind other bundles. To retrieve it, your technicians are forced into a dangerous and time-consuming cycle:
- The Shuffle: Using a forklift to move three bundles of “obstruction” material just to get to the target piece.
- The Damage: Every time you move stock unnecessarily, you risk damaging machined surfaces or bending lighter gauge tubing.
- The Safety Hazard: Manual handling of heavy cut-offs or awkward reaching into static racks is a leading cause of crushed fingers and back injuries in the shop.

The Solution: 100% Extension for Overhead Crane Access
Il cremagliera telescopica a sbalzo is engineered specifically to solve the accessibility issue. By allowing the cantilever arms to extend 100% out from the column (like a drawer), we completely expose the material to the aisle.
This design shift aligns perfectly with maintenance shop infrastructure. Most repair shops are equipped with overhead bridge cranes or jib cranes. With a roll-out system, you eliminate the need to maneuver a forklift into tight aisles. Your technician simply cranks the drawer out, drops the crane hook or sling directly vertically onto the load, and lifts it straight up.
Key Operational Advantages:
- Zero “Digging”: Each level is independent. You can access the bottom drawer just as fast as the top drawer.
- Preserved Material Integrity: Sensitive materials like polished stainless steel shafts or threaded rods are stored on UHMW-lined arms (optional) and are never dragged across other materials.
- Rapid Visual Inventory: You can see exactly what stock you have on hand, preventing the common MRO mistake of ordering rush-delivery steel when you actually had a piece hidden in the back of a static rack.

Reclaiming Floor Space for Repair Work
Space in a maintenance shop is at a premium. You need room for welding tables, disassembly benches, and machinery repair zones. Traditional static racks require wide aisles—often 12 to 14 feet—to allow a forklift to turn 90 degrees with a 20-foot long load.
Con il passaggio a A sbalzo, you can slash that aisle width requirement significantly. Since the loading is done from above via crane, the aisle only needs to be wide enough for a person to walk. This allows you to condense your steel storage footprint by up to 50%, freeing up valuable square footage for productive repair work.
Comparison: Static vs. Roll-Out in MRO
| Caratteristica | Static Cantilever Rack | Scaffale a sbalzo Roll Out |
|---|---|---|
| Metodo di accesso | Forklift (Requires wide aisle) | Overhead Crane (Zero aisle turn radius) |
| Tempo di recupero | 15-25 Minutes (Digging required) | 2-4 Minutes (Direct access) |
| Stock Visibility | Poor (Buried items are lost) | Excellent (Full drawer extension) |
| Efficienza dello spazio | Low (Lots of “air” and aisle space) | High (Compact, vertical density) |

Technical Reliability for Heavy Loads
Maintenance shops often deal with “mystery weights”—heavy solid rounds, thick-wall pipes, and tool steel. Our racks are built with structural steel I-beams and high-grade bearings to handle these realities.
- Capacità: Standard units handle 2,000 to 6,600 lbs Per livello.
- Lengths: Accommodates standard 20 ft or 24 ft raw material lengths.
- Operation: Available in manual crank (geared for ease) or electric drive for high-frequency use.
Frequently Asked Questions (Maintenance Shop Edition)
Q1: Our shop floor is already crowded. How much space do I really need for the “drawers” to open?
You only need clear space equal to the depth of the cantilever arm (typically 30 to 48 inches) in front of the rack. Unlike forklift aisles that need 12+ feet, this space is only occupied temporarily while you are actively retrieving material.
Q2: We store a lot of “short ends” and cut-offs. Will they fall through the arms?
No. We can outfit the cremagliera telescopica a sbalzo with steel pans or wire mesh decking on specific levels creates a solid shelf, perfect for storing short bars, motors, or spare parts alongside your long stock.
Q3: Do I need a forklift to install this?
Yes, you will need a forklift or your overhead crane for the initial installation to stand the columns up. However, once bolted down, daily operation is 100% crane-friendly.
Q4: Can one person operate the manual crank with a full 5,000 lb load?
Absolutely. The transmission system uses a high-ratio gear reduction. A single operator can crank out a fully loaded drawer with minimal physical effort, adhering to ergonomic safety standards.
Q5: We have specific lengths of hydraulic cylinder rod stock. Can the arm spacing be customized?
Yes. We customize the number of columns and their spacing based on the deflection properties of your material. For flexible materials like small diameter tubing or plastic rods, we add more arms to prevent sagging.
