The XSC Series autonomous mobile robots (AMRs) offer 800–2,000 kg load capacities, 3D LiDAR SLAM navigation, and flexible manual/autonomous operation for efficient pallet transport, stacking, and warehouse automation.
The XSC series counterbalance stacking AMRs support seamless connection with multiple automated peripheral devices including conveyors, automatic doors and robotic arms. They also feature compatible interfaces to dock mainstream management systems such as WMS, MES and ERP, enabling full linkage with AS/RS and forming an integrated end-to-end intelligent warehouse automation system. Rich customizable attachments (sideshifters, fork positioners etc.) further boost compatibility with diverse automated production and storage lines
Integration with AS/RS, Conveyors and Other Automated Systems
Fitted with automatic charging function and matching optional lithium-ion automatic charging stations, the robots realize unattended round-the-clock operation without frequent manual battery replacement. Built with lithium batteries and an optional battery heating system for low-temperature charging scenarios, they support both indoor and semi-outdoor working environments to achieve all-day continuous automated material handling. The one-button manual/automatic switching design also ensures flexible intervention without halting overall workflow.
24/7 All-Weather Automated Continuous Operation
All four models (XSC081/XSC121/XSC151/XSC201) provide multiple customizable fork dimensions, load backrest sizes and pallet-adapted specifications, matching mainstream standard pallet sizes like 1000×600 and 1250×500. With narrow aisle working capability (minimum aisle width down to 2.9m), optimized turning radius and compact chassis design, they smoothly traverse narrow warehouse passages and stably carry all standard pallet types. Polyurethane durable wheels also guarantee stable movement on common warehouse floors
Superior Trafficability: Compatible with all standard pallets
Equipped with 2-stage standard masts with optional backrests, the series offers multiple adjustable lifting heights. XSC081/XSC121 reach a max lift height of 2340mm while XSC151/XSC201 hit 2100mm, with extended mast height up to over 5000mm on customized mast options (up to 4000mm lifting height as shown in mast parameter table). It adapts to high-level dense rack storage, effectively utilizing vertical warehouse space and expanding overall storage capacity. The mast supports forward/backward tilt function to secure stacked goods during lifting.
High-Level Stacking for High-Density Storage
Application
The XSC Series autonomous counterbalance stackers are designed for flexible warehouse automation, including high-rack stacking, pallet storage and retrieval, and long-distance material transport. Available with load capacities from 800 to 2,000 kg, the series is ideal for warehouses, distribution centers, and manufacturing facilities. Featuring 3D LiDAR SLAM navigation without additional infrastructure, one-button switching between manual and autonomous operation, and seamless integration with WMS, MES, and ERP systems, the XSC Series enables efficient and adaptable automated material handling.
