Barcode Positioning Narrow Aisle Pallet Stacker Crane for Automated Warehousing

Barcode Positioning Narrow Aisle Pallet Stacker Crane for Automated Warehousing

Product Overview

The barcode positioning narrow aisle pallet stacker crane is an automated aisle handling device designed for automated warehousing, AS/RS pallet storage, and high-bay narrow aisle warehouse systems. It is mainly used for pallet storage and retrieval between rack locations and conveyor interface sections inside automated warehouse aisles.

This equipment adopts a double column stacker crane structure and supports single deep or double deep, single position fork configurations according to the storage layout. Through coordinated travel, lifting, and fork extension movement, the crane completes pallet storage and retrieval tasks in high-density warehouse systems. The rated load is up to 2000 kg, and the total equipment height is up to 24 m, making it suitable for palletized goods handling in manufacturing warehouses, logistics centers, e-commerce warehouses, and other automated pallet storage projects.

The system supports barcode positioning or laser positioning for storage addressing, while communication with warehouse systems is supported through wireless communication and industrial Ethernet. For warehouses that require repeatable rack access and controlled pallet movement in narrow aisles, this crane is a practical engineering solution.

Application Background

In automated warehousing projects, narrow aisle stacker cranes are usually expected to:

• support high-density pallet storage in aisle-based rack layouts
• handle medium to heavy pallet loads with repeatable positioning
• coordinate travel, lifting, and fork movement under warehouse control logic
• match rack geometry, conveyor interfaces, and storage addressing systems
• reduce reliance on manual forklift movement inside storage aisles

For narrow aisle high-bay storage layouts, manual forklift operation is limited by aisle width, storage height, and handling efficiency requirements. In this type of application, a pallet stacker crane is used to complete automated storage and retrieval inside the aisle while maintaining controlled motion and repeatable access to storage positions.

Technical Solution

This equipment mainly consists of a double column main structure, traveling mechanism, lifting mechanism, fork mechanism, wire rope lifting system, power supply system, addressing system, and electrical control system. During operation, the crane travels along the aisle, lifts to the designated storage level, and extends the fork to complete pallet placement or retrieval at the assigned rack location.

The system can be configured with single deep or double deep fork arrangements according to the project storage density and rack layout. Storage positions are identified through barcode or laser positioning, while machine-side communication is supported through wireless communication and warehouse-side system connection is supported through industrial Ethernet.

• Wire rope lifting method for controlled vertical movement
• Sliding contact line power supply for continuous aisle operation
• Barcode or laser positioning for storage location identification
• Frequency converter or servo drive for motion control

Application Boundary

This page refers to a pallet stacker crane used for automated pallet storage and retrieval inside narrow aisle high-bay warehouse systems. It is mainly intended for palletized goods with defined pallet dimensions, rack clearances, aisle geometry, and load center conditions.

Project-specific items such as travel distance, lifting stroke, rack height, aisle length, fork depth, load center, and pallet dimensions should be confirmed separately according to the actual warehouse design. If the project involves cold storage, strong corrosion, or other special operating conditions, the structural and electrical configuration should be confirmed by project.

Applications

Automated Warehouses
Used for pallet storage and retrieval in structured automated warehousing systems.

Narrow Aisle High-Bay Warehouses
Suitable for aisle-based pallet storage layouts requiring higher vertical space utilization.

Automated Storage and Retrieval Systems (AS/RS)
Used for automated pallet handling inside rack aisles and connected conveyor sections.

Pallet Logistics Centers
Suitable for palletized goods storage and transfer in high-density logistics environments.

E-commerce Warehouses
Used for pallet storage and replenishment handling in automated fulfillment operations.

Manufacturing Warehouses
Suitable for palletized raw materials, semi-finished goods, or finished goods storage in factory warehouse systems.

Third-Party Logistics (3PL) Warehouses
Used for palletized goods handling in shared automated warehouse projects.

Smart Warehouse Systems
Applicable where pallet storage, conveyor interfaces, and warehouse control logic are combined into an integrated automated handling system.

System Integration

This pallet stacker crane can be integrated with:

• AS/RS infeed and outfeed conveyor sections
• warehouse management systems (WMS)
• warehouse control systems (WCS)
• barcode identification systems
• laser positioning systems
• automated pallet conveyor lines
• high-bay rack storage systems

In most projects, the equipment works as a core aisle handling unit within a complete automated warehouse system rather than as a standalone machine.

Precise Pallet Handling Capability
The equipment supports travel accuracy of ±5 mm, lifting accuracy of ±5 mm, and fork accuracy of ±3 mm for repeatable pallet transfer.

Practical System Integration
It can be connected with WMS, WCS, conveyor interfaces, and warehouse positioning systems through industrial Ethernet and wireless

communication.

Configurable Fork and Drive Options
The crane supports single deep or double deep fork configurations and frequency converter / servo drive options according to project design.
