Continuous Pallet Handling Warehouse Storage Shelving Movable Pallet Racking System

Continuous Pallet Handling Auto Storage System for -25°C Cold Storage Warehouses

１．Product Overview

This auto storage system is designed for cold storage warehouses, cold chain logistics, and low-temperature pallet automation projects that require continuous pallet movement between inbound stations, outbound stations, buffer sections, transfer points, and storage areas. It is suitable for pallet-based automated warehouse management where low-temperature adaptability, stable conveying rhythm, and system-level control are required in the same project.

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 pallet storage, the pallet stacker crane supports heights up to 24 m and rated 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 cold storage warehouses that need continuous pallet flow, high-bay storage, and WMS-based task coordination under refrigerated conditions.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet transport path between inbound points, buffer areas, process interfaces, and outbound stations. These conveyor modules provide standard conveying speeds of 12 / 14 / 16 m/min and are suitable for continuous pallet movement in low-temperature warehouse operations.

Where pallet direction change or route switching is required, the lift transfer unit is used as the interface module between conveyor lines. Where floor-to-floor or level-to-level pallet transfer is needed, the rack and pinion lift provides vertical connection with a lift load of 1000 / 2000 kg and positioning accuracy of ±2 mm. For high-bay storage and retrieval, the pallet stacker crane is used as the core aisle storage equipment, with a maximum height of 24 m and rated pallet load 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 project control logic and warehouse configuration. This allows the storage system to connect pallet conveying, transfer, storage, and retrieval into one coordinated automated workflow.

３．Specifications

４．Application

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

It is suitable for food cold chain warehouses, refrigerated distribution centers, finished goods cold storage, and manufacturing warehouses that store temperature-sensitive palletized materials.

It is also suitable for low-temperature ASRS projects, pallet warehouse automation systems, and warehouse layouts that require continuous pallet handling between conveyor lines, lift transfer sections, and storage aisles.

５．Processing

Pallets enter the system from the inbound station and move through chain conveyors or roller conveyors to buffer zones, process interfaces, or transfer points.

When route change is required, the lift transfer unit redirects pallets between conveyor lines. When level change is required, the rack and pinion lift connects different floors or storage levels with controlled positioning.

For storage operations, the pallet stacker crane receives pallets from the conveyor interface, stores them in assigned rack positions, and retrieves them when outbound tasks are released. WMS communicates with the system through Industrial Ethernet to coordinate location assignment, pallet movement, storage tasks, and outbound sequencing.

６．Advantages

The system supports low-temperature operation from -25℃ to 5℃, which is suitable for refrigerated warehouses and cold chain logistics projects where standard room-temperature equipment may not be sufficient.

The pallet conveyor section supports 500 / 1000 / 1200 / 2000 kg load classes, which gives the system flexibility for different pallet weights and warehouse handling conditions.

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 heights up to 24 m and rated loads up to 2000 kg, making the system suitable for high-bay storage and pallet ASRS applications.

The system supports Industrial Ethernet communication with WMS and can use laser or barcode positioning, which helps connect storage tasks, equipment movement, 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 conveyor and storage configuration is appropriate.

Warehouse temperature is another key factor. For cold storage projects operating at -25℃ to 5℃, the low-temperature conveyor configuration should be confirmed together with the 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 suitable. If the project includes multi-floor transfer or level change, the lift load and ±2 mm positioning requirement of the rack and pinion lift should also be reviewed.

Finally, WMS communication method, positioning logic, inbound/outbound task pattern, and required throughput rhythm should be confirmed before final system configuration.
