följdsvagnar

Följdsvagnar, often translated as "trailer trains" or "road trains," are vehicles consisting of a tractor unit pulling multiple trailers or semi-trailers in a train-like formation. This configuration is primarily employed for transporting large volumes of goods over long distances, particularly in regions with vast and sparsely populated areas. The concept behind följdsvagnar is to maximize payload efficiency by consolidating multiple loads onto a single towing unit, thereby reducing the number of vehicles and drivers required.

The design of följdsvagnar can vary significantly depending on the intended cargo and the regulations of the operating country. Common configurations involve a lead truck or tractor unit that pulls one or more semi-trailers. In some cases, the trailers are connected directly to each other, while in others, dollies or intermediate axles are used to support the additional trailers. The length and number of trailers are strictly regulated to ensure safety and maintain roadworthiness.

Följdsvagnar are most prevalent in countries like Australia, where they are known as road trains and are crucial for the transport of goods across immense distances. They are also utilized in parts of North America, South America, and Africa. The advantages include reduced transportation costs, lower emissions per ton-mile compared to multiple individual trucks, and increased logistical efficiency. However, their operation requires specialized training for drivers due to the complex handling characteristics, and their use is often restricted to specific routes and highways due to their size and weight.
