New SINOTRUK SITRAK G7 660HP 6x4 Tractor Truck
The new SINOTRUK SITRAK G7 660HP 6x4 tractor truck is a high-power heavy-duty prime mover developed for long-distance transportation, heavy-haul operations, mining logistics and specialized trailer applications.
Powered by a Weichai WP15H660E50 diesel engine, the truck delivers 660 horsepower for demanding transportation conditions. The reinforced chassis, heavy-duty drive axles and 90# fifth wheel provide a strong foundation for transporting heavy machinery, mining equipment, bulk cargo and other high-load materials.
The G7S-E cab provides a spacious and comfortable working environment. Air-suspension seats, electric windows, four-point cab air suspension, an adjustable steering wheel and a heating and ventilation system help reduce driver fatigue during long-distance operations.
Product Advantages
Powerful 660 HP Engine
