Overview
Shitong Cold Chain Gravity Carton Flow Racking is specifically designed for chilled and frozen warehouses. With cold-resistant rollers and anti-condensation design, it ensures reliable FIFO flow even in subzero conditions.

How It Works
Cartons are loaded from the rear and roll forward automatically on cold-rated rollers. Bearings and lubricants are optimized for low temperatures, preventing freezing or seizing. The design minimizes frost buildup to keep lanes clear and efficient.

Key Features

• Operates reliably in -30°C to +5°C environments.

• Cold-resistant bearings and sealed rollers for smooth flow.

• Frost- and condensation-resistant structure.

• Dense storage layout reduces energy costs in cold rooms.

Customer Value

• Maintains FIFO rotation to protect product freshness.

• Minimizes downtime from frozen or jammed lanes.

• Improves energy efficiency by maximizing cubic storage.

Applications
Frozen food storage, seafood distribution, dairy products, pharmaceuticals, and any cold chain logistics operation.

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
