félpótkocsit

Félpótkocsit translates from Hungarian to English as "semi-trailer." It is a type of trailer that is designed to be coupled to a prime mover or tractor unit, forming a semi-trailer truck. Unlike a full trailer, a semi-trailer lacks front axles and its load is transferred to the tractor unit. This design allows for a more maneuverable combination and is commonly used for transporting goods over long distances.

The semi-trailer consists of a chassis, a floor, and sides, often with a roof. It is typically equipped with a kingpin at the front, which engages with a fifth wheel coupling on the tractor. This allows for articulation, enabling the truck to turn corners. Semi-trailers come in a wide variety of types, each designed for specific cargo. Examples include box trailers for general goods, flatbeds for oversized items, tank trailers for liquids or gases, and refrigerated trailers for perishable items. The length and weight capacity of semi-trailers are subject to regulations that vary by country. Their use is fundamental to modern logistics and freight transportation.
