A semi-trailer, also known as a semi-trailer, is a trailer that is towed behind a tractor unit or semi-trailer truck and is used to transport freight on roads. The term “semi-” refers to the fact that the semi-trailer only has a front axle and rests on the road at the rear end, while the front end is attached to the tractor unit's fifth wheel coupling. Semi-trailers are available in various sizes and designs to meet the different requirements of freight transportation. They can be configured for the transportation of standard freight, such as pallets or containers, as well as for special requirements, such as refrigerated or freezer transport. The versatility of semi-trailers makes them an important part of the logistics industry for the road transportation of goods. The tractor unit, also known as a semi-trailer truck, serves as the towing vehicle for the semi-trailer and helps to transport the freight safely and efficiently. It is capable of pulling heavy loads and offers high maneuverability on roads and highways. The use of semi-trailers offers a variety of advantages for freight transportation. They allow flexible use for the transportation of different types of freight and can be easily interchanged between different tractor units. They also offer efficient use of road infrastructure and help to reduce empty runs and emissions. Overall, semi-trailers are an indispensable part of modern logistics for the road transportation of goods. Their versatility, efficiency and reliability make them a preferred choice for companies and hauliers looking for a safe and cost-effective solution for transporting goods.
