Geely Racks Global Technical FAQ & Smart Warehouse Storage Systems
Pallet & Storage Racking Systems
What are the primary applications of Selective Pallet Racking systems?
Selective Pallet Racking is the most versatile solution for warehouses requiring direct, 100% access to every single pallet. It supports heavy loads (up to 4,500 kg per level) and works with standard forklifts. It is ideal for facilities with multiple SKUs and fast-turnover products.
• Max load capacity: 4,500 kg per level
• Accessibility: 100% direct product selectivity
When should a warehouse implement Double-Deep Pallet Racking instead of Standard Pallet Racking?
Double-Deep Racking is best when you want to increase storage density by up to 30% without resorting to fully automated solutions. It stores pallets two-deep, requiring a specialized deep-reach forklift. It is highly suited for products with medium to long shelf-life and identical SKUs.
• Capacity improvement: Up to 30% storage density boost
• Lift requirement: Deep-reach forklift models
What is the differences between Drive-in Racking and Push-Back Racking?
Drive-in Racking uses a LIFO (Last-In, First-Out) method where forklifts enter the rack channels, ideal for low-rotation, high-volume products. Push-Back Racking stores up to 6 pallets deep on nested carts, where gravity feeds the pallets forward, reducing forklift travel time and lowering collision risks.
• Drive-in method: LIFO configuration (for high-volume SKUs)
• Push-back depths: Nested rolling carts (2 to 6 pallets deep)
How does Gravity Flow Racking operate, and what are its key benefits?
Gravity Flow Racking utilizes inclined roller tracks that allow pallets to slide from the loading side to the picking side via gravity. It operates on a strict FIFO (First-In, First-Out) principle, making it perfect for perishable goods, high-turnover retail items, and rapid order replenishment.
• Rotation protocol: Strict FIFO (First-In, First-Out)
• Mechanics: Gravity-powered high-grade roller beds
What are the design criteria for Cantilever Racking systems?
Cantilever Racking is engineered for long, bulky, or oddly-shaped items like steel pipes, lumber, PVC tubes, and furniture. Crucial design criteria include arm length, load weight distribution, and selecting either single-sided or double-sided upright configurations to ensure perfect structural stability.
• Storage profile: Oversized, long, or non-palletized cargo
• Steel options: Single-sided or double-sided industrial frames
What is Narrow Aisle (VNA) Racking and when is it recommended?
Very Narrow Aisle (VNA) Racking compresses forklift aisles down to 1.5–1.8 meters. By maximizing vertical height up to 15 meters, it boosts storage capacity by up to 40% compared to standard systems, requiring specialized VNA turret trucks or guided forklift systems.
• Minimum aisle width: 1.5 to 1.8 meters
• Vertical threshold: Heights up to 15 meters
How do Mezzanine Racking and Combination Platforms optimize vertical warehouse space?
Mezzanine Racking transforms unused overhead space into multi-level storage floors. Built on heavy-duty steel profiles (typically Q235B), they support light-to-medium hand-picked goods, workstations, or extra offices, doubling or tripling active floor area without structural building modifications.
• Construction standard: Heavy-duty cold-rolled steel structures
• Layer capacity: 200 kg to 1,000 kg per square meter
What is the maximum load capacity for Geely Racks Heavy-Duty Shelving?
Our heavy-duty shelving systems are engineered to comfortably support loads ranging from 1,000 kg up to 5,000 kg per layer. The exact capacity depends on the custom-rolled profile width, upright column thickness (1.5mm to 3.0mm), and selected support beam dimensions.
• Rated loading: 1,000 kg to 5,000 kg per layer
• Steel gauge: Uprights ranging from 1.5mm to 3.0mm thickness
Can Geely Racks design storage systems specifically for cold storage facilities?

What is the difference between AGV and RGV systems in modern warehouses?
Automated Guided Vehicles (AGVs) navigate dynamically across the warehouse floor using lasers, magnets, or visual sensors to move materials. Rail Guided Vehicles (RGVs) are high-speed shuttle cars running on fixed rail tracks, optimized for high-volume, straight-line transport between production lines and storage areas.
• AGV pathing: Laser-guided, visual grid, or magnetic trackless paths
• RGV speedway: Linear high-speed fixed metallic guide rails
What vertical height limits can Geely Racks automated high-bay AS/RS structures reach?
Our automated high-bay AS/RS structures can be designed to reach heights of up to 40 meters. These systems require precise manufacturing tolerances (often less than ±1.5mm) and heavy-duty anchoring systems to guarantee structural alignment with high-speed automated stacker cranes.
• Height capability: Custom solutions up to 40 meters
• Column tolerance: Ultra-precise limits below ±1.5mm deviation
How does 5G-enabled scheduling enhance shuttle and AGV coordinates?
5G integration allows for ultra-low latency (<10ms) communication between automated warehouse equipment and the central WMS. This enables dozens of AGVs and shuttle carts to coordinate tasks simultaneously, eliminating bottlenecks and preventing equipment collisions in high-speed zones.
• Latency profile: Ultra-responsive <10ms data link speeds
• Operational scale: Massive concurrent device tracking matrixes
What are the main benefits of integrating Automated Stacker Cranes?
