The GKS 11 has a gross weight of 18,000 kg against an unladen weight of 7,740 kg, giving a payload of 10,260 kg. At a length of 6,600 mm, a width of 2,450 mm and an axle spacing of 2,800 mm, it is a compact but load-capable heavy trailer, whose short axle spacing eases manoeuvring in the confined space of a plant yard.
With a gross weight of 18,000 kg, the GKS 11 falls into EU category O4, where an air brake system is standard. A trailer of this size serves an asphalt-plant maker's own works traffic: moving plant components, binder or spare parts between the works and the construction site. Unlike a semi-trailer combination built for the open road, such a works trailer is usually laid out for short, repeated runs between production and storage.
On a used trailer of this weight class, what counts is the condition of the air brake system along with its lines and brake cylinders, rust on the frame, chassis rails and coupling, tyre condition and the function of the lighting. After almost four decades in service, the frame is also worth checking closely for cracks, deep-seated corrosion and earlier repair welds.

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.
