Applications

Heavy haulage in mining operations: Capable of carrying 80–85 tons, this model delivers a fuel consumption rate of 42 L/100 km in mountainous areas. Its anti-corrosion chassis offers 30% longer service life, and the vehicle performs reliably across a wide temperature range from –30°C to 55°C.
Oversized equipment transport: Can tow 120-ton axle trailers, making it ideal for moving non-standard cargo such as wind turbine blades, construction machinery, and other large-scale equipment.
Agricultural logistics: Equipped with a 420 HP engine and a reinforced 50-ton chassis, the 6×4 tractor performs well on mixed terrain, including gravel farm roads and highways. The corrosion-resistant cargo box design ensures safe and efficient transport of grain, fruits, and vegetables.
Building materials transport: Featuring a 50-ton reinforced chassis, 420 HP engine, and manual transmission, this unit is suited for short-haul concrete transfers from batching plants as well as interprovincial transport of sand and stone. The vibration-damping chassis reduces the risk of damage to precast cement products.
