Järbo Alustrong VVF4-112: a heavy EU class O4 trailer with a 35,000 kg gross weight, a 11,650 mm length and a 26,000 kg payload, registered in Finland
With a gross weight of 35,000 kg, the Alustrong VVF4-112 falls into EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes. Trailers of this weight class are pure commercial haulage units, running as part of a combination behind heavy rigs.

Empty, the trailer weighs 9,000 kg, against a permitted gross weight of 35,000 kg, giving a payload of 26,000 kg - more than three quarters of the permitted gross weight. At 11,650 mm long and 2,550 mm wide, it offers a long, wide loading area for heavy general cargo.
From trailer class O3 upward, a compressed-air braking system is mandatory, fitted as standard at this weight class. Driving such a combination requires a category CE licence in most EU states, since the permitted combined weight clearly exceeds the limits of category C. The high payload-to-tare ratio points to a weight-conscious build combined with a high load rating.
Buying a used trailer of this weight class, the condition of the frame and axle mounts matters, since a weight-conscious build responds more sensitively to repeated overloading than a heavier one. The air braking system should be checked for leaks and even action across all wheels, and corrosion in the frame welds is a common finding on older trailers of this class, along with wear in the drawbar coupling and its pivot bushing.
