The most common accident scenarios include a full frontal collision or a roll-over accident. When the cab is struck by an exterior object, its primary task is to transfer energy backwards in order to maintain sufficient survival space inside.
At Volvo Trucks we test our cabs thoroughly in a series of sequences, including the front pendulum test. And all cabs meet Swedish cab strength standards – the toughest in the world.
Absorbing the energy of the impact
There are tremendous forces at work in case of an accident. The power exposed to your body is likely to be at least twice the weight of your entire body. A person weighing 100 kg is exposed to a force equal to four tonnes when travelling at 50 km/h. That is why the cab interior needs to be energy-absorbent, in order to yield to the impact of the human body.
In all our cabins the steering wheel and the dashboard are energy-absorbent, as are the trims at knee height. All upholstery fabrics are also made of flameproof materials.
In addition, interior accessories such as the refrigerator and coffee maker are designed to be firmly attached to the cab structure. This ensures that they stay in place in case of collision or emergency braking manoeuvres.
