semitraileri

Semitrailer, also known as a semitrailer truck or semitruck, is a type of heavy-duty vehicle used for transporting goods over long distances. It consists of a trailer, which carries the cargo, and a tractor unit, which pulls the trailer. The tractor unit typically has a cab for the driver and a power unit, which can be a diesel engine or an electric motor. The trailer is connected to the tractor unit via a fifth wheel or a gooseneck hitch.

Semitrailers are commonly used in the transportation of goods such as automobiles, construction materials, and agricultural products. They are designed to carry heavy loads and can travel long distances, making them ideal for interstate and international transportation. The size and capacity of semitrailers can vary, with some being able to carry up to 80,000 pounds (36,287 kilograms) of cargo.

Semitrailers are operated by professional drivers who are licensed and trained to handle the large and heavy loads. They follow strict regulations and safety guidelines to ensure the safe transportation of goods. The use of semitrailers has significantly contributed to the efficiency and speed of the global supply chain, enabling the transportation of goods across vast distances in a timely manner.
