Faehtz HRF 1 – EU class O4 trailer: 18,000 kg gross vehicle weight, 15,260 kg unladen weight, 14.35 m long, 2.5 m wide, built 1975
With a gross vehicle weight of 18,000 kg, the Faehtz HRF 1 falls into EU trailer class O4, the heavy trailers and semi-trailers above 10 tonnes with their own air brake system, hauled in heavy-haulage traffic behind trucks or tractor units.

The HRF 1 was built in 1975, is 14,350 mm long, 2,500 mm wide and has a wheelbase of 7,400 mm. It has an unladen weight of 15,260 kg; against a gross vehicle weight of 18,000 kg, that leaves a payload of 2,740 kg.
At 14.35 m overall length with an unladen weight of 15,260 kg, already a large share of the gross vehicle weight, the HRF 1 is built for long but comparatively light loads, such as bulky building material or vehicles. The class O4 air brake system needs sound lines and working brake cylinders on every axle so that braking takes hold reliably along the whole length of the vehicle.
When buying a trailer this old and this long, the frame matters most: check the main beams for sagging, rust, cracks and earlier repair welds, and check the axles, axle bearings and suspension for wear. The brake system with its lines and cylinders, tyres and tread depth, lighting along the full length, and the coupling to the towing vehicle also belong on the checklist. With a build year of 1975, pay particular attention to corrosion on load-bearing parts after decades in service.

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.
