Applications

Agricultural product transport: Equipped with a 550 HP engine, the 6×4 tractor is built for composite conditions including rural gravel roads and highways. The cargo bed features anti-corrosion design, ensuring safe and efficient transport of grains, fruits, and vegetables.
Heavy-duty mining transport: Supports loads of up to 80-85 tons and performs reliably across a full temperature range from -30°C to 55°C, making it suitable for demanding mining operations.
Hazardous materials transport: Complies with Chinese regulatory standards for the safe configuration of vehicles transporting hazardous goods.
Cold chain logistics: Delivers compliant 35-ton payload capacity with an independent refrigeration power supply system. The 550 HP engine delivers high torque at low RPM, while temperature-controlled compartments maintain precise cooling from -25°C to 15°C, supporting long-distance refrigerated freight.
Building materials transport: Designed for both short-distance delivery from concrete batching plants and long-haul sand and gravel transport. The anti-vibration chassis helps reduce breakage of precast concrete products.
Oversized equipment transport: Capable of towing up to 150-ton modular trailers, ideal for the transport of wind turbine blades, construction equipment, and other non-standard loads.
