Josef Jais DAZ/18/PCFS: a drawbar trailer in EU class O4 with a 18,000 kg gross weight, a 9,400 mm length and a 13,570 kg payload for commercial haulage
With a gross weight of 18,000 kg, the DAZ/18/PCFS sits in EU trailer class O4, the heavy trailers above 10 tonnes. Vehicles in this weight class are almost always built as a classic drawbar trailer with a rigid or steered towing eye, running in commercial haulage behind lorries and articulated tractor units.

Empty, the trailer weighs 4,430 kg, against a permitted gross weight of 18,000 kg, giving a payload of 13,570 kg - a high share that points to a relatively light body on a load-rated chassis. At 9,400 mm long, 2,550 mm wide and with a 5,200 mm wheelbase, it offers a long, well-used loading area.
From trailer class O3 upward, a compressed-air braking system is mandatory, and it comes as standard at 18,000 kg; the simple overrun brake fitted to smaller O1 and O2 trailers would not be sufficient here. 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.
Buying a used trailer of this weight class, check the chassis first: cracks or through-corrosion on the main rails and the drawbar are the most common reason for failing a roadworthiness test. The braking system should be checked for leaks and even braking action across all wheels, and the axle bearings for play. With a payload of 13,570 kg available, it is also worth assessing the condition of the load bed and the lashing points.

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.
