Tractor unit

What are tractor units?

A tractor unit is a key component in the transportation industry, primarily designed for towing trailers. It's equipped with a fifth wheel coupling that connects them to a trailer or a semi-trailer. This connection allows for both the flexibility of changing trailers and the ability to carry significant weight.

In what industries are tractor units used?

  • Long-distance freight haulage. Tractor units are the backbone of cross-country and international goods transport over long distances.
  • Heavy industry and construction. In sectors like construction, mining, and large-scale manufacturing, tractor units are used to transport heavy machinery and materials. For example, tractor units with cranes significantly enhance efficiency in construction by enabling the swift loading and unloading.
  • Agriculture. Larger farms may use tractor units for transporting produce or large equipment.
  • Logistics and distribution. Within the logistics sector, they play a vital role in moving goods from ports, factories, and warehouses to distribution centres and retail outlets.
  • Specialized transport. They are also used for specialized transport, such as hauling oversized loads, tanker trailers for liquids, or refrigerated trailers for perishable goods.

What are the types of tractor units in terms of axle configuration?

Tractor units are designed with varying axle configurations to comply with axle load regulations. Common types include 4x2, 6x2, and 6x4. These are prevalent in long-distance transport in larger nations like the USA, whereas in Europe and the UK 4x2 and 6x2 models are more typical. The configurations 4x4, 6x6, 8x2, 8x4, 8x6, and 8x8, are largely dictated by axle load laws and maximum gross vehicle weights (GVWs). Tractor units used in heavy haulage or as road trains usually have four or more axles with several driven ones.
