High Bay Cold Storage Racking System 24m Pallet Stacker Crane 1000kg Shelving

High-Bay Cold Storage Auto Storage System with 24m Pallet Stacker Crane

１．Product Overview

This auto storage system is designed for high-bay cold storage warehouses that require automated pallet conveying, vertical transfer, storage, and retrieval under refrigerated operating conditions. It is suitable for projects where pallets need to move continuously between inbound sections, outbound sections, buffer zones, transfer points, and high-bay rack locations while maintaining stable flow in low-temperature environments.

Based on the provided configuration, the system can be built with chain conveyors, roller conveyors, lift transfer units, rack and pinion lifts, and pallet stacker cranes. The conveyor section supports pallet loads of 500 / 1000 / 1200 / 2000 kg and operating temperatures of -25℃~5℃ for low-temperature applications. For high-bay storage, the pallet stacker crane supports heights up to 24 m and rated pallet loads up to 2000 kg. For multi-level transfer, the rack and pinion lift provides ±2 mm positioning accuracy.

This makes the system suitable for refrigerated warehouse automation projects that require high storage density, continuous pallet handling, and warehouse task control through WMS communication.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet transport path between inbound points, buffer areas, process interfaces, outbound sections, and stacker crane interfaces. These conveyor modules provide standard conveying speeds of 12 / 14 / 16 m/min and support continuous pallet movement in refrigerated warehouse operations.

Where pallet route change is required, the lift transfer unit is used to connect conveyor directions and transfer pallets between process sections. Where level change is required, the rack and pinion lift provides vertical pallet transfer with lift loads of 1000 / 2000 kg and positioning accuracy of ±2 mm. For high-bay storage and retrieval, the pallet stacker crane works as the aisle storage module, supporting storage heights up to 24 m and rated pallet loads up to 2000 kg.

At the control level, the system supports Industrial Ethernet communication with WMS. Addressing can be based on laser positioning or barcode positioning, depending on warehouse control logic and site requirements. This allows pallet movement, storage assignment, inbound task execution, and outbound retrieval to be coordinated within one cold storage automation structure.

３．Specifications

４．Application

This system is suitable for high-bay cold storage warehouses that require continuous pallet infeed, pallet outfeed, transfer, buffering, and automated storage under refrigerated conditions.

It is commonly used in food cold chain warehouses, frozen goods storage, refrigerated distribution centers, finished goods cold storage, and pallet ASRS projects where high-bay storage density and low-temperature operation are both required.

It is also suitable for automated warehouse projects where pallet movement between conveyor sections, lift interfaces, transfer points, and storage aisles needs to be managed as one connected cold chain process.

５．Processing

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

Where direction change is required, the lift transfer unit redirects pallets between conveyor routes. Where vertical connection is needed between floors or levels, the rack and pinion lift transfers pallets 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 location assignment, inventory updates, and outbound sequencing 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 pallet handling 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 in multi-level layouts.

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

Industrial Ethernet communication with WMS supports coordinated storage tasks, pallet movement control, and inventory management within one warehouse automation structure.

７．How to Choose

Selection should begin with pallet type, pallet size, and actual pallet weight. This determines whether 500 kg, 1000 kg, 1200 kg, or 2000 kg conveyor and storage configuration is appropriate.

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

If the project 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 suitable. If the layout includes floor transfer or level 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 throughput target should be confirmed before the final system combination is defined.
