lavettiyhdistelmä

The term "lavettiyhdistelmä" is a Finnish word that translates to "trailer combination" or "articulated vehicle" in English. It refers to a type of road vehicle composed of a tractor unit (vetoauto) and one or more semi-trailers (puoliperävaunu). This configuration is commonly used for transporting large quantities of goods over long distances.

A key characteristic of a lavettiyhdistelmä is that the trailer is attached to the tractor unit via a fifth wheel coupling. This allows the trailer to pivot relative to the tractor, enabling it to follow the tractor's path more closely than a traditional trailer-and-truck combination. This flexibility is crucial for maneuverability, especially when navigating curves or tight spaces.

Lavettiyhdistelmät are designed for efficiency and capacity. The separation of the tractor unit and the trailer allows for easier loading and unloading, as the trailer can be uncoupled and parked while the tractor unit is used for other tasks. This system is prevalent in the logistics and freight transportation industries worldwide, contributing significantly to the global supply chain. The specific dimensions and weight limits for lavettiyhdistelmät are regulated by national and international transport laws.
