The SIASUN G-20-30X is an outdoor autonomous tow tractor built for heavy-duty material transport, offered in rated towing capacities of 20,000, 25,000 and 30,000 kg. Its navigation stack fuses multi-source perception — 3D LiDAR, GNSS/RTK satellite positioning, inertial navigation and vision sensors — to deliver accurate positioning and intelligent path planning in complex, changing outdoor environments. SIASUN's patented automatic coupling and decoupling technology allows the tractor to dock with and release its load cart entirely on its own, turning heavy trailer moves into a fully autonomous cycle. The vehicle travels at up to 2.2 m/s unloaded and 1.5 m/s at full load, with hydraulic power-assisted braking and a rear-wheel-drive layout keeping multi-tonne loads under controlled, safe motion.

The G-20-30X is designed for modern smart factories, warehouses, production logistics and process-driven material handling — anywhere repeatable transport, accurate positioning and safe autonomous operation are required on outdoor routes. Typical deployments include automotive production, lithium battery manufacturing, 3C electronics, pharmaceuticals, food and photovoltaic production, where the tractor works with dispatch and intelligent scheduling software to keep material flow consistent while reducing manual handling. Purchasing is quotation-based, so availability, final configuration and integration requirements are confirmed for each project before ordering.
