lisäakselien

Lisäakselien, often translated as "additional axles" or "tag axles," refers to extra axles added to a vehicle, typically a truck or bus, beyond its standard drive and steering axles. These additional axles are usually non-driven and are installed to increase the vehicle's load-carrying capacity. By distributing the weight of a heavy load over more axles, the stress on each individual axle and the road surface is reduced. This allows for the transport of heavier goods that would otherwise exceed the legal weight limits for vehicles with fewer axles.

The implementation of lisäakselien is a common practice in industries such as heavy haulage, construction, and logistics, where payloads are frequently substantial. The installation of these axles can be a permanent modification or a temporary solution, depending on the operational needs. Some additional axles are steerable, which improves maneuverability, especially for long or articulated vehicles. Others are fixed and primarily serve to support the load. Regulations regarding the number, spacing, and weight limits for lisäakselien vary significantly by region and country, influencing their design and application. The concept aims to optimize transport efficiency and road infrastructure preservation by managing heavy loads more effectively.
