Fruehauf Benalu Neptune 64 – heavy EU class O4 trailer: 43,000 kg gross weight, 38,000 kg payload, 14.03 m length, built in 2000.
With a gross weight of 43,000 kg, the Fruehauf Benalu Neptune 64 falls into EU trailer class O4, well above the 10-tonne threshold for heavy trailers and semi-trailers. Trailers of this weight class are designed for long-haul work behind articulated tractor units or heavy towing vehicles, where the load is spread across several axles.

With an unladen weight of 5,000 kg, payload comes to 38,000 kg, nearly nine-tenths of the gross weight. At 14.03 m long and 2.55 m wide, the Neptune 64 is among the longer vehicles in its weight class; the very low unladen weight relative to payload points to a consistently lightweight chassis and body design.
Class O4 trailers are fitted throughout with air brakes, usually with air suspension on at least one axle to protect the chassis and load. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight, plus a professional driver qualification for commercial use.
When buying a lightweight semi-trailer built in 2000, a careful check of the frame for fatigue cracks is worthwhile, precisely because the low unladen weight leaves little reserve against overload. Check the axle suspension and brake drums for even wear, check the air lines for leaks at the coupling heads, and inspect the body for corrosion or deformation at the mounting points to the chassis.

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.
