A tractor unit is essentially a towing engine for heavy-duty work. It provides power for hauling either a towed load or a trailered load. They are usually equipped with diesel engines to optimize power and durability, besides the fact that they are more cost-efficient this way. Tractor units contain two to five axles and a multi-ratio transmission for top flexibility in gearing. In some cases, a tractor unit with a connected trailer is preferred over a regular truck because it makes it more manoeuvrable.
A tractor unit can be disengaged from a trailer and reused immediately after, without having to wait for the transport to be unloaded. This makes the tractor unit more versatile and time-efficient if they are to haul freight overland. Tractor units can tow a great variety of trailers. Liquids, gasses and many dry goods can be hauled by tractor units in tankers. Tractor units commonly have a single cabin and a short bed.
6x2 and 4x2
For long-haul and heavy transport work in Europe, the 6x2 tractor units are commonly used. It’s a tractor unit that has three axles, of which only one is being driven. They get the heaviest jobs done. For lighter transport, the 4x2 is used more often. These tractor units are more flexible and therefore well suited for shorter distance transport.
