Intelligent Stacker Palletized Unit Load Storage Retrieval

Home Products Automated Storage and Retrieval System (AS/RS)Stacker Crane Double Column Stacker

Product Introduction
Product Parameters

The double-column stacker crane is a core material handling device in smart warehousing systems, designed for efficient storage and retrieval of palletized or boxed unit loads. As a robust two-column stacker crane, it delivers superior strength and stability for medium- to heavy-duty automated warehouse operations. The system can be fully customized to meet project-specific requirements, with flexible options for load capacity, height, extension positions, workstations, and track types (straight or curved). Whether used as a double-column narrow-aisle stacker or a double-column ASRS pallet handler, this solution adapts seamlessly to a wide range of warehouse layouts and operational demands.

Features

Advanced Design
Built as a rigid double-column stacker crane system, the twin-mast structure ensures excellent load stability and minimizes sway during high-speed movement. The modular design supports single or double cargo positions and single or double fork extensions, allowing the customized double-column stacker to fit various rack depths and storage densities. With heights up to 13 meters and capacities up to 300 kg, it handles diverse load sizes with ease.

High Performance
The double-column pallet stacker crane achieves travel speeds of up to 240 m/min and lifting speeds of up to 60 m/min, significantly reducing cycle times and increasing throughput. Fork mechanisms operate at 40 m/min for fast and accurate pick-and-place. These performance metrics make it a reliable choice for high-demand distribution centers and automated warehouses.

Safety & Reliability
Engineered for 24/7 operation, the double-column ASRS pallet handler features heavy-duty steel construction, servo motors for precise control, and integrated safety systems including obstacle detection, anti-collision sensors, and emergency braking. The twin-mast design provides better load distribution, reducing wear and extending equipment life.

Wide Application
This double-column stacker crane system is suitable for automated warehouses, cold chains, manufacturing lines, and e-commerce fulfillment centers. It handles pallets, cartons, trays, and custom carriers across industries such as food & beverage, automotive, pharmaceuticals, and retail. As a customized double-column stacker, it adapts to straight or curved tracks, narrow aisles, and multi-deep racking, ensuring a tailored fit for every project.

FAQs

What defines the structural layout of a Double-Column Stacker Crane, and when should it be preferred?

A Double-Column (Twin-Mast) Stacker Crane features a highly rigid frame engineered with two vertical structural masts enclosing the lifting platform. This heavy-duty design should be preferred over single-column options when your facility handles extreme payload capacities, non-standard ultra-wide load profiles, or when lifting cargo to maximum vertical heights. The twin-mast architecture distributes mechanical stress evenly, ensuring absolute structural safety for heavy industrial storage.
Can the double-column stacker crane operate on curved tracks to manage multiple warehouse aisles?

Yes, absolutely. Depending on your throughput requirements and layout constraints, our double-column stacker cranes can be customized with curved rail configurations. This allows a single, high-capacity crane to transition seamlessly out of its active narrow aisle, cross a curved transfer zone, and enter a adjacent lane. This flexible track layout optimizes asset utilization and significantly lowers total hardware investment costs for lower-frequency, high-capacity storage tiers.
