Overview
Shitong’s High Density Gravity Carton Flow Racking maximizes storage capacity while maintaining strict FIFO rotation. By converting static shelves into dynamic gravity lanes, it allows cartons to flow automatically to the pick face, saving labor and improving picking speed.

How It Works
Cartons are loaded from the rear and travel forward on gravity-driven rollers until they reach the front picking face. As each item is picked, the next carton slides smoothly into position. This ensures continuous availability and reduces picker travel distance.

Key Features

• Gravity lanes designed for deep storage of up to 12+ cartons per SKU.

• Adjustable incline (3–5°) to match carton size and weight.

• Reinforced side rails to prevent skewing or jams.

• Modular roller beds for quick reconfiguration.

Customer Value

• Dramatically improves space utilization and pick efficiency.

• Ensures FIFO handling for perishable or date-sensitive products.

• Reduces handling errors by creating one clear pick face per SKU.

Applications
Food and beverage warehouses, e-commerce fulfillment centers, pharmaceutical storage, and high-turnover retail operations.

FAQ:

1. How many parts does carton flow racking have?
Main parts include upright frame, beam, roller track or wheel bed, separator, roller support rail, and carton stop plate.
Optional parts include frame protector, upright protector, lane divider, and pick-to-light accessories.

2. How to control the speed of cartons on carton flow racking?
The flow speed depends on the lane incline and roller type. By adjusting the angle (usually 3–5°) or using brake rollers, the cartons will flow smoothly without impact.

3. What is the load capacity per carton?
Typically, each lane position can carry 20–50 kg per carton, depending on the roller system. Per lane capacity can reach 200–400 kg.

4. Will cartons get stuck when they flow down?
No, proper debugging will eliminate this. Correct roller spacing, lane angle, and carton base quality ensure smooth flow.

5. How long can a carton flow lane be?
Standard lanes are 6–12 cartons deep, but Shitong has manufactured lanes up to 20 cartons deep. Longer designs can be customized if required.

6. What are the main characteristics of carton flow racking?

• High density storage and picking efficiency

• Goods flow automatically by gravity, First In First Out

• Continuous replenishment from the rear, convenient picking in the front

• Suitable for fast-moving SKUs with large quantity but small variety

• Improves ergonomics and reduces picker walking distance
