Gravity Flow Racking System (FIFO High-Density Storage) , Gravity Pallet Flow Rack, Heavy Duty Gravity Racking System

Product Description

Gravity Flow Racking System

Gravity flow racking, known as roller or self-sliding pallet racking, is a high-density storage system based on gravity sliding principle.Upgraded from beam racking, it has inclined roller tracks (2°–5° gradient). Pallets slide from loading to unloading end by weight, with dampers, bumpers, and separators for strict First-In-First-Out (FIFO).Driven by pure gravity, without electric components and aisles, suitable for large-batch, low-SKU, fast-turnover or shelf-life-sensitive goods. It improves space utilization and efficiency, widely used in cold chain, food, pharmaceutical industries.

Specification

Core Features
1. Pure gravity drive with no motors or electronic components, achieving zero energy use, low noise, high stability, and no power loss.
2. Mandatory FIFO ensures clear batch management, avoiding overstock and expiration, adapting to shelf-life control.
3. Dense storage cancels forklift aisles, boosting space use by 30%–60% over beam racking.
4. Separation of loading and unloading, no need for forklifts inside, ensuring clear routes and reducing collision risks by 80%.
5. Tracks with dampers, bumpers, separators, and guards enable stable sliding, anti-impact, and easy picking.
6. Customizable height, layers, and load, compatible with pallets and forklift/AGV operations, adaptable to normal and cold storage.
7. Sturdy structure with wear-resistant, anti-damage components, long life, minimal maintenance.

Product Advantages

Upgraded Warehousing Efficiency

Simultaneous loading/unloading reduces forklift backtracking and waiting, boosting handling efficiency by 40%. No manual pallet flow reduces labor costs, achieving semi-automated operations.

Maximized Space Utilization

High-density design increases cargo positions, storage density near drive-in racking, retaining FIFO and standardized management.

Lower Operational Costs

No electrical equipment, no motor or control system maintenance, near-zero maintenance costs. Q235B/stainless steel structure is wear/corrosion-resistant, reducing replacement costs.

Comprehensive Cargo Protection

Protective components and uniform sliding reduce collision/extrusion damage, improve intact rate, ideal for fragile, vulnerable, high-value goods.

Standardized Inventory Management

The FIFO mode suits batch management and shelf-life control for food, pharma, cold chain, etc., meeting storage standards. Strong Scene Adaptability

Customizable for warehouse floor height and load, supporting normal and -18℃ cold storage, clean workshops, forklifts, stackers, AGVs, and more.

Product Types

Mainstream types are divided into 4 categories based on scenarios, load and design, supporting custom adjustments:
1.Heavy-duty cold-rolled steel gravity flow racking: Made of Q235B steel, with a pallet load of 800–1500kg, height 6–10m, ideal for heavy pallet storage.
2.Cold storage-specific gravity flow racking: Uses cold-resistant coating/stainless steel, with anti-freezing dampers, for -18℃ cold storage without embrittlement.
3.Light/medium-duty gravity flow racking: Handles a pallet load of 500–800kg, height ≤6m, for small/medium warehouses and e-commerce storage.
4.Narrow aisle gravity flow racking: Optimized for narrow aisles with adjusted track width, enhancing space use, suitable for taller warehouses.

FAQ

1. Can the track gradient of gravity flow racking be adjusted?

Standard track gradient is 2°–5°, adjustable (≤6°) by pallet weight and cargo features. Gradient is professionally designed to prevent excess speed or pallet retention. Customer self-adjustment is not advised.

2. Does gravity flow racking support LIFO?

No. The core logic of gravity flow racking is mandatory FIFO. For LIFO, consider drive-in or push-back racking. Manufacturer can recommend types based on needs.

3. What special requirements for gravity flow racking in cold storage?

Cold storage models require cold-resistant epoxy or 304 stainless steel, with optional anti-freezing speed dampers and bumpers. Manufacturer offers full cold storage solutions.

4. What is the max single pallet load of gravity flow racking?

Standard single pallet load is 500–1500kg. Heavy-duty models with max load 2000kg are customizable, needing thickened steel and optimized tracks. Specific load per stress report.

5. Can gravity flow racking be moved or modified post-installation?

Racking is bolt-fixed, fully disassemblable, and modifiable (e.g., layer number, track depth) per layout. Major changes need pro-calculations to ensure stability.

6. What is the service life of gravity flow racking?

Main structure (Q235B/304 steel) lasts ≥10 years under normal use; rollers and dampers last 3–5 years. Manufacturer offers lifelong parts replacement with clear pricing.

7. How to judge if my warehouse suits gravity flow racking?

A warehouse suits gravity flow racking if it meets core conditions: large-batch, low-SKU goods, shelf-life/batch needs, high-density storage, standard pallet use. Manufacturer offers free on-site survey and design solutions.

8. Difference between gravity flow racking and shuttle racking?

Gravity flow racking uses gravity for cost-effective, low-maintenance FIFO, high-density storage; shuttle racking, driven by shuttle cars, supports FIFO/LIFO with higher automation for large warehouses and fast-turnover items but incurs higher costs and requires maintenance.

9. What after-sales services does the manufacturer provide?

Main structure warranty ≥5 years, vulnerable parts 1 year; free non-man-made damage repair/replacement within warranty; lifelong cost-price parts and technical support post-warranty; 24-hour nationwide response to after-sales, with on-site engineer service.

10. Can free warehouse layout design be provided?

Yes. Provide warehouse floor plan (L×W×H), column positions, pallet specs, load needs, and tool types. Manufacturer's designers deliver a free floor plan, 3D racking drawing, and detailed quote in 3 working days.
