AS/RS Stacker Crane selective pallet storage and retrieval solution

The AS/RS (Automated Storage and Retrieval System) Stacker Crane Selective Pallet Storage and Retrieval Solution is a core intelligent warehousing solution for industrial logistics, manufacturing, cold chain, e-commerce fulfillment and special environment scenarios. It integrates mechanical equipment, automatic control and intelligent software to realize fully automated pallet in-out, high-precision inventory management and vertical space optimization, replacing traditional manual warehousing and solving pain points like low space utilization, high labor costs and inefficient inventory management. Positioned as a high-performance, reliable and scalable system, it adapts to diversified pallet warehousing needs and serves as core infrastructure for enterprises building intelligent warehousing and digital supply chains.
Core Definition: AS/RS is a complete intelligent warehousing system consisting of high-rise racks, aisle stacker cranes, in-out conveyor systems, automatic control systems, computer warehouse management systems and peripherals, enabling automatic material storage/retrieval and full-process digital management. The stacker crane is the core execution equipment for selective pallet access, handling precise pallet transfer between racks and conveyor ports.
Compared with traditional single-layer manual and semi-automatic warehouses, this solution delivers outstanding benefits in space efficiency, operational speed, intelligent management and scenario adaptability, driving long-term cost reduction and efficiency gains for enterprises. Core advantages are as follows:

This AS/RS stacker crane solution maximizes warehouse vertical space utilization to an industry-leading level, with unit area storage capacity reaching 4-7 times that of traditional single-layer warehouses. It makes full use of high-rise vertical storage space, greatly reduces warehouse land occupation and infrastructure costs, and realizes high-density pallet storage while retaining full selective pallet access functionality, making it the optimal choice for enterprises with limited warehouse space or large-scale storage demands.

Full mechanization and automation eliminate reliance on manual handling, shelving and picking. This cuts labor and management costs while reducing manual safety risks; it also greatly improves in-out speed, shortens material turnover cycles, and adapts to high-efficiency modern production and supply chain demands.

Equipped with advanced WMS (Warehouse Management System) and WCS (Warehouse Control System), it enables real-time monitoring of inventory, equipment status and work tasks, realizing digital and visual management. Computerized control enforces strict FIFO, preventing cargo aging, damage and loss; real-time, accurate inventory data eliminates manual counting errors and supports reliable production and supply chain planning.

The in-out system connects directly with enterprise production lines, enabling one-stop automated flow from finished product output to warehousing, and warehouse retrieval to production feeding. It cuts intermediate manual links, reduces operational errors and product damage, integrating production and warehousing to boost overall industrial chain efficiency.

Suitable for dark, low-temperature, toxic and other harsh environments unsuitable for long-term manual work. Fully computer-controlled unmanned operation ensures normal cargo access, protects worker safety, and expands application to cold chain, chemical and food processing industries.

Standardized pallet/bin storage, paired with stacker crane high-precision stable operation, avoids collisions, extrusion and rough manual handling. This significantly reduces cargo damage compared to manual warehousing, cutting enterprise economic losses and improving cargo integrity.
This highly integrated system includes five core modules with coordinated operation to form a full closed-loop pallet warehousing process. Its selective access function allows independent retrieval of any single pallet without disrupting others, a key advantage over dense storage systems.

Material & Structure: As the main load-bearing structure, the rack system uses high-strength steel, mainly beam-type or corbel-type, and is fully customized to match warehouse height, pallet specifications, load weight and actual site conditions.
Size & Storage Layout: With a standard height ranging from 10 to 40 meters, it forms dense and standardized cargo grids dedicated to storing pallets and material boxes, laying a solid hardware foundation for three-dimensional high-density storage.
Core Functional Advantages: Beyond basic load-bearing, this system significantly boosts vertical storage capacity, lowers cargo damage rates, supports strict FIFO (First In, First Out) operation logic, and lays the groundwork for automated and precise inventory control throughout the warehousing cycle.

Structure Classification: The stacker crane is the core execution equipment of the solution, divided into single-column and double-column models, which are matched to different warehouse heights and operational efficiency requirements for targeted adaptation.
Core Operating Mechanisms & Control System: It is equipped with walking, lifting and fork drive mechanisms, paired with international advanced servo control systems and absolute addressing systems to achieve full closed-loop control. Barcode or laser ranging technology is adopted to realize high-precision cargo positioning.
Industry-Leading Technical Parameters: With a maximum load capacity of about 8 tons and a maximum travel speed of up to 400m/min, it achieves fast, stable and reliable pallet handling, fully meeting the high-intensity operation needs of large-scale warehousing centers.

Core Function & Positioning: As the core peripheral handling equipment of the AS/RS system, it undertakes horizontal and vertical pallet transportation, connecting warehouse inbound and outbound ports with the stacker crane working area to realize smooth and uninterrupted cargo transfer.
Common Equipment Types: Includes multiple adaptable models such as roller conveyors, chain conveyors, lifting tables, distribution vehicles, elevators and belt conveyors, covering full-scenario material handling needs.
Customized Configuration Logic: Equipment types and combinations are selected and matched according to actual warehouse site layout, pallet load weight, and overall warehousing workflow, to ensure continuous, efficient and stable operation of the entire handling link.

Large-scale intelligent warehousing projects can add Automated Guided Vehicles (AGV) as auxiliary handling equipment, realizing seamless connection between production lines, warehouses and distribution zones, and full-process unmanned handling from production to delivery.

System Composition: This system integrates complete software and hardware configurations. The software covers three core modules: barcode reading control, electronic display control, and 3D warehouse management; the hardware includes barcode/RFID scanners, automatic transmission devices, sorting tables and stacker crane electrical control cabinets.
Core Unmanned Operation Functions: It can automatically complete a full set of warehousing operations without manual intervention, including cargo identification, cargo location display, warehousing and shelving, outbound picking, track transmission and cargo destination allocation.
Management Advantages: It realizes full-process digital and visual management of the entire warehousing link, ensuring operational accuracy and improving the overall transparency and management efficiency of warehouse operations.
As the core execution unit, the stacker crane’s stable, high-precision operation defines overall system performance. It relies on six core technical functions for efficient, accurate selective pallet access:
