The Sandvik Toro TH320 is a compact, agile underground mining truck specifically engineered for narrow-vein operations and confined tunnel environments. With a payload capacity of 20 metric tonnes, this mid-sized hauler offers exceptional performance in smaller drift sizes without compromising productivity.
Designed to work efficiently in combination with 3.9 yd3 (3.0 m3) loaders such as the Sandvik LH307, the TH320 combines powerful engine performance, robust frame construction, and operator-focused ergonomics to deliver optimal hauling efficiency in hard rock mining conditions. Its compact dimensions, excellent maneuverability, and advanced safety features make it a reliable solution for mining operations seeking high-capacity performance in tight underground spaces.
