Bröderna Forss P751 – EU class O4 trailer: 11,990 kg gross vehicle weight, 4,740 kg unladen weight, 8.68 m long, 2,400 mm wide, built 1954
With a gross vehicle weight of 11,990 kg, the Bröderna Forss P751 falls into EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes hauled in long-distance haulage with their own air brake system, whether behind a tractor unit or as a drawbar trailer. Vehicles of this size spread their weight across several axles and need a load-bearing chassis.

The Bröderna Forss P751 was built in 1954 and has an unladen weight of 4,740 kg; against a gross vehicle weight of 11,990 kg, that leaves a payload of 7,250 kg. Overall length is 8,680 mm, width 2,400 mm. The wheelbase is 5,290 mm, spread across 4 wheels. The permitted top speed is 100 km/h.
Trailers and semi-trailers in this weight class carry the actual load volume in road haulage, while the towing vehicle supplies only drive and steering. For the air brake to work at full effect, lines, brake cylinders and linings all have to work together without fault; without an intact brake coupling between towing vehicle and trailer, the combination may not be driven. The ratio of unladen weight to payload is within the usual range for this class.
When buying used, an air-braked trailer of this size lives or dies on the brake system: check lines, brake cylinders and linings for corrosion, leaks and wear. Inspect the chassis and frame for rust and cracks, along with axle bearings, suspension, tyres and tread depth, lighting, and the coupling to the towing vehicle. With a build year of 1954, budget for a limited spare-parts supply for brakes and axles too.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
