1.2T Autonomous Stacker with Unique Dual Forks for Narrow Aisle Stacking-XNA121
Description
Explore the XNA121
Compact Design
Requiring only 1.65 meters of aisle width and a turning diameter under 1.8 meters, the XNA121 maximizes storage density. Its compact size allows it to maneuver seamlessly between racks, enabling higher storage capacity without infrastructure changes.
Double Forks
The sideways fork design allows it to pick up and place pallets without turning, significantly improving handling efficiency in narrow aisles. This configuration minimizes cycle time and enhances throughput in space-limited environments.
Advanced Navigation
Equipped with 3D SLAM and QR hybrid navigation, the XNA121 ensures millimetre-level positioning accuracy. Its 3D camera system enables precise load alignment and stacking, even at high elevations providing stability and accuracy.
Versatile Handling
Built with a high-strength chassis, the XNA121 handles various non-standard or non-square pallets with ease. Integrated safety features, including active obstacle avoidance and collision alarms, guarantee safe, reliable operation alongside your employees.
Application
The XNA121 is built for narrow-aisle, high-density storage environments where space and efficiency are critical. It performs best in narrow-aisle high-level racking, medium-level racking, and VNA (Very Narrow Aisle) warehouse setups. With stacking heights reaching up to 8.5 meters, it enables full utilization of vertical space while maintaining safe and precise pallet handling. Its unique two-way stacking capability enhances flexibility for diverse storage configurations, making it an ideal solution for modern smart warehouses.
