Tractor Units: The Powerhouses of Logistics Transportation
Tractor units, also known as truck tractors or semi-trucks, are indispensable components of modern logistics and transportation systems. They are not designed to carry cargo themselves; instead, they function by connecting to trailers or other towed equipment to accomplish long-haul freight transport or specialized tasks. Tractor units, with their powerful engines, maneuverable handling, and reliable performance, serve as the “powerhouses” of the logistics industry, driving the wheels of global commerce.
