Tractor Truck is a heavy-duty transportation tool that plays an important role in logistics, construction and mining. It usually consists of parts such as a sturdy frame, a powerful engine, a stable suspension system and an efficient braking system. The design of semi tractor trailer trucks enable it to tow a variety of semi-trailers or full-trailers, thus carrying a large amount of cargo for long or short-distance transportation. This kind of vehicle has excellent traction ability and driving stability, and can drive smoothly in complex roads and operating environments.
