Explore our range of heavy-duty cantilever systems certified for structural safety and tailored for industrial loads.
Unlike traditional pallet racking, cantilever systems require precise structural mechanics to safely hold long, heavy, and awkward loads without structural failure.
Our systems are engineered using High-Yield Structural Steel (Q235B and Q355B). We compute precise structural load factors using finite element analysis (FEA) to minimize deflection ratios, conforming strictly to the L/180 maximum limit under full dynamic load capacity.
Single-sided structures maximize space efficiency along perimeter walls, while double-sided configurations offer balanced center-aisle structural stability. Custom counter-weighted bases distribute load vectors across concrete foundations, minimizing floor strain.
Featuring custom adjustable heights in increments of 75mm or 100mm, our arms incorporate vertical tapers. When loaded, the arms level out, preventing lumber, steel tubes, or heavy bar stock from rolling or sliding forward.
Always calculate the product load distribution by positioning the center of gravity closest to the vertical column upright. Placing loads at the outermost tip of the arm increases the bending moment by up to 300%, compromising the safety factor and structural warranty.
Standard industrial shelving fails when accommodating oversized long stock. Our solutions address spatial challenges in core global sectors.
In timber distribution hubs, lumber must remain flat to prevent warping. Our heavy-duty cantilevers use continuous horizontal support planes without front vertical columns, enabling rapid loading by side-loaders and forklifts. Standard arms carry 1,000kg to 1,500kg each, preventing sagging across lengthy framing lumber, wood panels, and MDF sheets.
Metal tubes present safety hazards when stacked high. Our specialized pipe arms are manufactured with end-stops (removable or welded pins) to ensure safe load retention. Heavy bar stock, dynamic coils, and structural rebar bundles are stored safely, preventing accidental roll-offs and optimizing vertical space by up to 250%.
| Industry Segment | Typical Material Load | Recommended Arm Type |
|---|---|---|
| Lumber & Panels | 800 - 1,200 kg | Straight Arm (Tapered 2°) |
| Steel Pipes / Tubes | 1,000 - 1,800 kg | Pipe Arm with End-Stop Pins |
| Industrial Rebar | 1,500 - 2,500 kg | Super Heavy-Duty I-Beam Arm |
| Coils & Reels | 1,200 - 2,000 kg | Curved/Axle-Supporting Arm |
Established in 2015, Shenzhen Lijin Storage Equipment Co., Ltd. is a global manufacturing leader specializing in high-capacity warehouse racking, automated industrial systems, and structural cantilever shelving.
Our QA laboratory executes ultrasonic non-destructive testing (NDT), automated weld inspections, laser dimensional verification, and heavy-load cycle endurance testing. Powered by our 35-person quality assurance division, every batch is verified against dynamic shear, material tensile limits, and impact deformation standards.
In North America, Western Europe, and Southeast Asia, over 850 structural supply chain partners depend on our high-volume production lines. Our team successfully launched 85 customized automated configurations last year alone, ensuring structural synergy with modern materials handling equipment.
From raw structural coils to certified protective coatings, our factory floor utilizes heavy industrial precision equipment.
Continuous investment in modern steel processing machinery ensures precise structural profiles and consistent weld quality.
We design and manufacture structural systems compliant with major global warehousing standards, ensuring safety, liability protection, and building permit approval.
Our heavy-duty industrial systems conform to RMI (Rack Manufacturers Institute) MH16.3 for structural steel cantilevered systems, alongside European EN 15635 guidelines. We maintain structural safety margins under dynamic loading, vertical deflection limits, and floor-anchoring bolt requirements.
For zones with high seismic activity, we engineer uprights with wider footprint plates, heavier wall thickness steel profiles, and robust cross-braced frames. These custom components meet localized building codes, minimizing structural sway under horizontal seismic forces.
Modern warehousing relies on automated integration. Our R&D engineers design systems for seamless, next-generation automation.
High-bay cantilever structures integrated with automated stacker cranes (AS/RS). Our high-precision manufacturing maintains plumb tolerances within ±2mm across heights exceeding 15 meters, allowing automated cranes to navigate aisles safely.
Integrating structural health monitoring into premium systems. Using localized strain gauges embedded within the cantilever arms, operators receive automatic notifications via WMS/ERP if an arm deflects beyond safe thresholds.
For chemical and outdoor applications, we offer C5-M rated hot-dip galvanization and outdoor-grade thermosetting polyester powder coatings. These provide superior protection against salt fog, extreme humidity, and UV exposure.
Common engineering, specification, and safety questions answered by our technical design team.
Arm capacity is determined by bending moment capacity ($M_w$) and sheer strength limit, calculated as $M = F \times d$, where $F$ represents load weight and $d$ represents the distance from the load center to the vertical upright. Placing a load farther from the column increases the bending moment, reducing overall carrying capacity.
Roll-formed steel is ideal for light-to-medium loads (up to 1,000kg per arm) due to its cost-efficiency. However, for extreme applications, heavy impact hazards, and loads exceeding 1,500kg per arm, hot-rolled structural steel I-beams offer superior resistance to impact deformation and fatigue.
Vertical and horizontal bracing panels connect adjacent upright columns. This design forms a rigid, structural frame structure that transfers lateral shear forces down to the floor slab anchor bolts, preventing cumulative frame twisting.
