lavettiyhdistelmät

Lavettiyhdistelmät refer to specialized trailer combinations used in Finland for transporting oversized or exceptionally heavy loads. These combinations are designed to meet specific regulatory requirements and safety standards for road transport of such cargo. They typically involve a prime mover (truck) and one or more trailers, often modular or extendable, to accommodate different load dimensions and weights.

The use of lavettiyhdistelmät is crucial for industries like construction, heavy machinery manufacturing, and infrastructure projects. They enable the movement of items that cannot be transported by standard road vehicles, such as large industrial components, wind turbine parts, or specialized construction equipment. The configuration of a lavettiyhdistelmä is carefully planned based on the load's characteristics, including its weight, length, width, and height.

These combinations often require special permits and escort vehicles, depending on the size of the load and the route. The planning process involves detailed route surveys to ensure bridges, tunnels, and other infrastructure can safely accommodate the combination. Professional drivers with specific training are essential for operating these complex vehicles, emphasizing safety and adherence to traffic regulations. The term itself combines "lavetti," referring to a type of low-loader trailer, with "yhdistelmät," meaning combinations, thus describing the specialized truck-trailer setups.
