500kg – 2000kg Auto Storage System Automated Racking Solutions For Refrigerated Warehouse

１．Product Overview

This pallet auto storage system is designed for refrigerated warehouse automation where pallets need to move continuously between inbound stations, outbound stations, buffer sections, transfer points, and high-bay storage areas under low-temperature conditions. It is suitable for cold storage warehouses, cold chain logistics centers, and automated pallet warehouses that require both stable material flow and system-based warehouse management.

Based on the listed configuration, the system can be built with chain conveyors, roller conveyors, lift transfer units, rack and pinion lifts, and pallet stacker cranes. The pallet conveying section supports load classes from 500 kg to 2000 kg, with conveying speeds of 12 / 14 / 16 m/min. The low-temperature operating range is -25℃~5℃, which makes the system suitable for refrigerated pallet handling and cold chain warehouse automation.

For vertical transfer and high-bay storage, the rack and pinion lift supports lift loads of 1000 / 2000 kg and positioning accuracy of ±2 mm. The pallet stacker crane supports heights up to 24 m and rated pallet loads up to 2000 kg. At the warehouse control level, the system supports WMS communication through Industrial Ethernet and uses laser or barcode positioning for addressing.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet transport path between receiving points, storage interfaces, buffer areas, process connections, and shipping sections. These modules support continuous pallet movement in refrigerated environments and can be selected according to pallet load class, line layout, and operating rhythm.

Where pallet route change is required, the lift transfer unit is used to connect conveyor directions and transfer pallets between process sections. Where vertical connection is needed between different warehouse levels, the rack and pinion lift provides stable pallet lifting with controlled positioning. For high-bay pallet storage and retrieval, the pallet stacker crane works as the aisle storage module for pallet put-away and outbound retrieval.

At the control level, the system communicates with WMS through Industrial Ethernet. Addressing can be based on laser positioning or barcode positioning, depending on site conditions and warehouse control logic. This allows pallet conveying, transfer, storage, retrieval, and inventory task management to work together within one refrigerated warehouse automation structure.

３．Specifications

４．Application

This system is suitable for refrigerated warehouse automation projects that require pallet infeed, pallet outfeed, buffering, transfer, and high-bay storage under low-temperature conditions.

It is commonly used in cold storage warehouses, cold chain logistics centers, food distribution warehouses, finished goods refrigerated storage, and pallet ASRS projects where continuous pallet handling is required.

It is also suitable for automated high-bay warehouses where pallet movement between conveyor lines, lift interfaces, transfer points, and storage aisles needs to be managed as one connected automation process.

５．Processing

Pallets enter the system through inbound conveyor lines and move through chain conveyors or roller conveyors to buffer areas, transfer sections, or storage interfaces.

Where direction change is needed, the lift transfer unit redirects pallets between conveyor paths. Where level change is required, the rack and pinion lift transfers pallets vertically between different warehouse levels with controlled positioning.

For storage operations, the pallet stacker crane receives pallets from the interface section, stores them in assigned rack locations, and retrieves them when outbound tasks are released. WMS coordinates pallet routing, storage assignment, inventory updates, and outbound task execution through Industrial Ethernet communication.

６．Advantages

The system supports low-temperature operation from -25℃ to 5℃, which makes it suitable for refrigerated warehouses and cold chain logistics projects.

The pallet conveyor section supports 500 / 1000 / 1200 / 2000 kg load classes, which allows the system to match different pallet weights and warehouse handling requirements.

Conveying speeds of 12 / 14 / 16 m/min support continuous pallet flow between inbound, outbound, buffer, and transfer sections.

The rack and pinion lift provides ±2 mm positioning accuracy, which is useful for level transfer, interface docking, and stable pallet handover.

The pallet stacker crane supports heights up to 24 m and rated loads up to 2000 kg, making the system suitable for high-bay refrigerated pallet storage.

Industrial Ethernet communication with WMS helps connect pallet transport, storage tasks, and inventory control within one warehouse management structure.

７．How to Choose

Selection should begin with pallet type, pallet size, and actual pallet load. This determines whether 500 kg, 1000 kg, 1200 kg, or 2000 kg configuration is suitable for conveying and storage.

Warehouse temperature is another key condition. For refrigerated projects operating at -25℃~5℃, the low-temperature conveyor and transfer configuration should be confirmed together with actual frost, moisture, and operating rhythm conditions.

If the warehouse uses high-bay racks, the required storage height and aisle arrangement should be checked to confirm whether a pallet stacker crane up to 24 m is appropriate. If the project includes level transfer or floor connection, the lift load and ±2 mm positioning requirement of the rack and pinion lift should also be reviewed.

Finally, WMS interface requirements, addressing method, inbound and outbound task logic, and required throughput rhythm should be confirmed before final equipment combination is defined.
