XUT320 underground mining hauler adopts hydromechanical transmission and articulated steering, fitted with mature imported core components. It fits non-coal underground mines with tunnel sections ≥3m×3m, and works with 3m³/4m³ LHDs for ore loading and haulage. Capable of high-temperature, humid, high-altitude and steep-slope harsh conditions, it delivers great trafficability, strong power, high reliability and wide adaptability. • Powerful Performance: Equipped with Volvo turbocharged engine and DANA electronically controlled transmission. It boasts strong traction and climbing capacity, with a heavy-load speed of 7.2km/h on 1:7 slopes. • Safe & Reliable: Integrated automatic braking, interlock braking, fault warning, rear-view camera, SAHR brake, steering and lifting locks to ensure safe operation. Built-in engine braking improves downhill safety; optional automatic fire suppression system and electric emergency steering handle emergencies. • Easy Maintenance: Standard centralized lubrication system. Concentrated external fuel/drain ports and service filters enable ground servicing; well-arranged doors and windows simplify inspection. Real-time machine monitoring and intelligent fault diagnosis streamline troubleshooting. • Wide Adaptability: Independent radiators for engine, hydraulic oil and transmission oil support stable operation at up to 50℃. Braided wiring harnesses and IP65-rated electric parts provide excellent waterproof performance. High-strength steel chassis and wear-resistant steel lining extend service life. • High Comfort: Ergonomic spacious cab with HVAC, adjustable steering wheel, air suspension seat and dual shock absorption. Engine braking avoids long-time continuous brake pedal operation on long downhill road.
