High Precision Pallet Stacker Crane Systems Double Column Pallet Storage 2000kg

High Precision Double Column Pallet Stacker Crane for Pallet Storage Systems

Product Overview

The double column high precision pallet stacker crane is an automated aisle handling device designed for pallet storage systems, AS/RS warehouses, and high-bay pallet handling projects. It is mainly used for automated pallet storage, retrieval, and transfer between rack positions and conveyor interface sections inside warehouse aisles.

This equipment adopts a double column stacker crane structure, which is suitable for high-bay racking systems and aisle-based pallet storage layouts. Through coordinated travel, lifting, and fork extension movement, the crane completes pallet storage and retrieval tasks with repeatable handling accuracy. The rated load is up to 2000 kg, and the total equipment height is up to 24 m, making it suitable for manufacturing warehouses, e-commerce warehouses, smart warehouse logistics centers, and other automated pallet storage applications.

The system supports barcode addressing or laser positioning, and can communicate with warehouse systems through industrial Ethernet and wireless communication. For projects that require controlled pallet movement, repeatable rack access, and integration with warehouse software systems, this crane is a practical engineering solution.

Application Background

In pallet storage systems, stacker cranes are usually expected to:

• support high-bay pallet storage and retrieval in aisle-based rack layouts
• handle medium to heavy pallet loads with repeatable movement accuracy
• coordinate travel, lifting, and fork handling under warehouse control logic
• match rack geometry, pallet dimensions, and conveyor interface requirements
• reduce manual forklift activity inside narrow storage aisles

For these warehouse layouts, manual handling efficiency is limited by aisle width, storage height, and storage density. A double column pallet stacker crane is used to perform automated pallet storage and retrieval inside the aisle while maintaining controlled motion and repeatable access to rack 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 rack level, and extends the fork to complete pallet placement or retrieval at the target storage location.

The system can be configured with single deep or double deep, single position fork arrangements according to the storage layout. Storage positions are identified through laser positioning or barcode addressing, while warehouse-side communication is handled through industrial Ethernet. Motion control can be configured through frequency converter drive or servo drive according to project requirements.

Transmission Features

• Double column stacker crane structure for high-bay pallet handling
• Single deep or double deep, single position fork options for different storage layouts
• 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 rack access
• Fork speed 30 m/min loaded / 40 m/min empty for pallet insertion and extraction
• Travel acceleration 0.6 m/s² / lifting acceleration 0.5 m/s² / fork acceleration 0.6 m/s²
• Positioning accuracy: Travel ±5 mm / Lifting ±5 mm / Fork ±3 mm
• Wire rope lifting method for controlled vertical movement
• Sliding contact line power supply for continuous aisle operation
• Laser or barcode positioning for storage address identification

Application Boundary

This page refers to a pallet stacker crane used for automated pallet storage and retrieval inside high-bay aisle-based 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, fork depth, rack layout, aisle length, warehouse height, and interface logic should be confirmed separately according to the actual warehouse design. If the project involves low-temperature storage, strong corrosion, or other special operating conditions, the structural and electrical configuration should be confirmed by project.

Automated Storage and Retrieval Systems (AS/RS)
Suitable for pallet handling between rack positions and conveyor interfaces in automated storage projects.

High-Bay Racking Systems
Used in pallet warehouses where vertical space utilization and aisle-based automation are required.

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

E-commerce Warehouses
Used for pallet storage and replenishment handling in high-density warehouse operations.

Smart Warehouse Logistics Centers
Suitable for pallet transfer and storage execution under warehouse software and task scheduling systems.

Pharmaceutical Warehouses
Used for palletized storage in warehouse environments requiring structured logistics control.

Food and Beverage Warehouses
Suitable for pallet handling projects requiring repeatable aisle access and high-bay storage management.

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.
