Do you manage high inventory volumes with a limited range of SKUs? A pallet flow racking system is one of the most efficient solutions for high-density warehouse storage and fast inventory rotation.
The Longwei Automation Modular Gravity Roller Conveyor is a core component designed specifically for pallet flow racking systems. It enables pallets to move smoothly along inclined lanes using gravity, supporting stable First-In, First-Out (FIFO) inventory management.
This modular system integrates gravity roller rails, brake rollers, pallet separators, entrance guide guardrails, and end stoppers into a complete pallet flow solution for warehouse storage and material handling applications.
Depending on warehouse layout and storage requirements, the system can be configured for lane depths of 3–4 pallets, 9–10 pallets, or 20+ pallets, with full customization based on pallet size, load capacity, and operational workflow.

Modular Design | Easy to handle, install, and replace |
Direct Rack Installation | Suitable for pallet flow racking systems |
Consistent Assembly | Improves installation accuracy |
Scalable Structure | Supports future warehouse expansion |
A brake roller, also known as a speed controller, is installed within roller rail lanes to help control pallet movement speed. This prevents pallets from moving too quickly along inclined lanes and supports safer unloading at the picking side.
Brake Roller Range | Application |
|---|---|
500–1000 kg | Standard pallet flow applications |
1000–1500 kg | Heavier pallet flow applications |
Function | Purpose |
|---|---|
Speed Control | Helps regulate pallet travel speed |
Safe Pallet Flow | Reduces uncontrolled pallet acceleration |
Load Protection | Helps prevent impact damage |
Operator Safety | Supports safer picking and unloading |
FIFO Stability | Maintains smooth pallet movement through the lane |
Operators can continuously load pallets into the system, where pallets accumulate in sequence until the lane reaches its designed storage capacity.
In deep-lane pallet flow systems, pallets may generate pressure against each other. The pallet separator helps create space and separation between pallets by holding back rear pallets while allowing the front pallet to be removed safely.
Benefit | Description |
|---|---|
Reduces Back Pressure | Prevents excessive pressure between pallets |
Improves Safety | Supports safer unloading in deep lanes |
Protects Goods | Helps reduce palletized load damage |
Enhances Throughput | Makes pallet picking smoother |
Supports Deep-lane Storage | Suitable for high-density pallet flow systems |
By integrating pallet separators into racking systems, warehouses can improve operational safety, storage density, and pallet flow efficiency.
