The register lists here 7 versions with unladen weights from 721 to 1,955 kg, a gross weight of a constant 3,500 kg, lengths from 5,630 to 8,060 mm and widths from 2,170 to 2,550 mm.
With a uniform gross weight of 3.5 tonnes but varying unladen weight and size, the PK range covers different payload levels within the same driving-licence class, from more compact models with a large payload reserve to bigger versions with more load area. Trailers of this kind are common among trades businesses, in landscaping and for private transport, usually towed behind cars or light vans, with the 3.5-tonne gross weight staying within the standard car driving-licence category.
When buying used, check the condition of the chassis and load floor, the operation of the overrun brake, the condition of the axles, wheel bearings and tyres, and the tightness of the tarpaulin or side boards. On the bigger, heavier versions it is also worth checking for chassis twist caused by overloading and corrosion on the drawbar and jockey wheel, as well as the lighting system and the condition of the coupling head.

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.
