Warehouse Storage Asrs Stacker Crane 800mm × 1400mm Overhead Stacker Crane

High Precision Double Column Pallet Stacker Crane for High-Bay Warehouse Storage

Product Overview

The double column pallet stacker crane is a core storage and retrieval device designed for high-bay warehouse storage, AS/RS pallet handling, and narrow aisle automated warehouse systems. It is mainly used for automated pallet storage and retrieval between rack positions and infeed or outfeed conveyor interfaces.

This equipment adopts a double column stacker crane structure, which is suitable for high-bay racking systems and narrow aisle warehouse layouts. Through the coordinated movement of the traveling mechanism, lifting mechanism, and fork mechanism, the crane completes pallet storage and retrieval tasks inside the aisle. The standard rated load is up to 2000 kg, and the total equipment height is up to 24 m, making it suitable for palletized goods storage in manufacturing warehouses, logistics centers, e-commerce fulfillment centers, and other high-density warehouse applications.

The system supports barcode addressing or laser positioning, and can communicate with warehouse control and management systems through wireless communication and industrial Ethernet. For automated pallet warehouses requiring repeatable handling accuracy, structured rack access, and reduced forklift aisle operations, this crane is a practical engineering solution.

Application Background

In high-bay automated pallet warehouses, stacker cranes are usually expected to:

• support high-density pallet storage in narrow aisles
• handle medium to heavy pallet loads with repeatable movement accuracy
• coordinate travel, lifting, and fork extension under warehouse control logic
• match rack geometry, conveyor interfaces, and storage addressing systems
• operate continuously in manufacturing, logistics, and distribution storage environments

For this type of warehouse layout, manual forklift access inside storage aisles is limited by height, aisle width, and storage density requirements. A double column pallet stacker crane is used to perform automated storage and retrieval inside the aisle while maintaining controlled movement and rack access accuracy.

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, single position fork arrangements according to project storage requirements. Storage positions are addressed through barcode or laser positioning, while command and management communication is supported through wireless communication and industrial Ethernet.

Transmission Features

• Double column stacker crane structure for high-bay pallet handling
• Rated load up to 2000 kg, with higher load confirmation by project if required
• Travel speed up to 200 m/min for aisle transfer efficiency
• Lifting speed 40 m/min loaded / 60 m/min empty for vertical storage access
• Fork speed 30 m/min loaded / 40 m/min empty for pallet insertion and extraction
• Travel positioning accuracy ±5 mm, lifting positioning accuracy ±5 mm, fork positioning accuracy ±3 mm
• Wire rope lifting method for vertical movement
• Sliding contact line power supply for continuous aisle operation
• Barcode or laser positioning for storage position addressing
• Frequency converter or servo drive for motion control

Application Boundary

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

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

Specifications

Applications

Automated Storage and Retrieval Systems (AS/RS)
Used for automated pallet storage and retrieval inside high-bay rack aisles.

High-Bay Warehouse Storage Systems
Suitable for narrow aisle pallet warehouses requiring higher vertical space utilization.

Manufacturing Warehouses
Used for palletized raw materials, semi-finished goods, or finished products in automated storage sections.

Logistics Distribution Centers
Suitable for pallet storage and transfer in high-density logistics handling environments.

E-commerce Fulfillment Centers
Used for palletized goods storage in automated warehouse and replenishment operations.

Food and Beverage Warehouses
Suitable for pallet storage projects requiring aisle-based automated access.

Pharmaceutical Logistics Warehouses
Used for structured pallet storage in controlled warehouse logistics systems.

Cold Chain and 3PL Warehouses
Can be applied in palletized storage systems when the project configuration is confirmed for the operating environment.

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 crane works as a core aisle handling unit within a complete automated warehouse system rather than as a standalone machine.
