The XNA121 is a 1.2-ton autonomous narrow aisle stacker for warehouse automation, operating in 1,650 mm aisles to maximize storage density and reduce aisle space by over 50%.
As the industry’s first heavy-duty dual-sided narrow aisle stacker with exclusive patents, it picks goods from both rack sides without side steering during forward/backward travel. It only requires a 1740mm narrow working aisle, slashing required storage aisle space by more than 50% and drastically boosting warehouse rack density. It supports 1500kg rated load and an industry-leading 13000mm maximum lifting height to make full use of vertical warehouse space.
Patented Dual-Sided Forks
It adopts integrated 3D SLAM LiDAR, QR code and vision camera fusion positioning, paired with adaptive lateral control algorithms. It achieves ±10mm target docking accuracy and less than 1cm straight-line lateral travel deviation, guaranteeing stable, error-free high-altitude pallet storage and retrieval in tight narrow rack aisles. Dual Wi-Fi/5G communication supports wireless multi-vehicle scheduling for coordinated unmanned operation
Multi-Sensor Fusion High-Precision Navigation & Positioning
Comprehensive multi-angle safety barriers eliminate operational risks: front cameras & dual side lasers, rear fork-tip and fork-base anti-collision lasers, front & rear physical bumpers, and front emergency stop button. It also comes with voice audio reminders, turn signals and zone warning lights, plus pallet in-place detection switches at the fork root, providing layered active collision prevention for high-lift narrow aisle work.
Full-Range Multi-Layer Active Safety Protection System
Matching DAS real-time data management system collects full-cycle goods movement data for transparent, digital warehouse monitoring. Built-in intelligent route algorithms automatically generate optimal handling paths, ideal storage locations and efficient scheduling aligned with production rhythms to realize first-in-first-out stock control. It supports optional auto-charging stations and seamless integration with enterprise management systems, enabling closed-loop unmanned digital warehousing to lift overall logistics throughput.
Intelligent DAS Digital Warehouse Management & Optimized Operation Logic
Application
The XNA121 autonomous narrow aisle stacker is designed for high-density warehouse automation, making it ideal for space-constrained warehouses, distribution centers, and automated pallet storage applications. With a 1.2-ton load capacity and the ability to operate in aisles as narrow as 1,650 mm without turning, it reduces aisle space requirements by over 50%. Its compact design enables efficient unmanned pallet handling while maximizing storage capacity and optimizing warehouse space utilization.
