The model designation (such as R 620) identifies the cab and the engine (in this case, an R cab and 580 engine). Other typical examples are P 310 and T 380. All models are available as tractors and rigids with axle configurations associated with highway and on/off road applications.

The many chassis/engine/cab combinations offer further choices, such as gearbox, frame strength, chassis height, and suspension systems. It’s very easy to select the principal options so that you can optimise the truck for long haulage, distribution, construction or more specialised work such as hazardous loads, heavy-haulage, emergency response, public utilities and so on.

According to the type of operation, heavy-duty frames and rear axle gears are available where the vehicle is likely to carry heavy loads or encounter difficult operating conditions.
