Huizinga KAHW – EU class O4 trailer: 20,000 kg gross vehicle weight, 2,760 kg payload, eight wheels, 8.02 m wheelbase, built in 2023.
With a gross weight of 20,000 kg, the Huizinga KAHW falls into EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes. Vehicles in this class take on loads in commercial goods transport that a single truck can no longer carry economically, running as a trailer behind a separate towing vehicle. They are used in long-distance haulage, construction traffic and the transport of machinery and bulk goods, where payload determines the economics of each run.

With an unladen weight of 17,240 kg, payload comes to 2,760 kg – so a large share of this trailer's weight sits in the chassis itself. At 13.95 m long, 2.51 m wide, on eight wheels and with an 8.02 m wheelbase, it stands on a long, heavy underframe.
From class O3 upwards, trailers of this size are generally fitted with air brakes rather than the simple overrun brake used on light trailers. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight. The air brake system must be checked annually for function and leak-tightness as part of the periodic roadworthiness test.
With this multi-axle design, it is worth checking the wheel hubs and brake drums of each axle individually when buying: uneven wear between axles points to a faulty load-equalising mechanism. Check the air-spring bellows or leaf springs for cracks, check the brake lines for chafing, and check the underrun guard and side marker lights for completeness. Check the tyres on all axles for matching tread and age, since mismatched tyres change the load distribution.
