Ajk OP – trailer range with 22.5-inch wheels: 8 versions, unladen weight from 7,320 to 12,210 kg, gross weight from 32,000 to 47,000 kg, lengths up to nearly 11 metres
Ajk builds a range of heavy commercial trailers under the designation OP, listed on this page. The model names in the range combine the code OP with two numeric values and the constant suffix 22.5, the wheel-rim size in inches commonly used in Europe for heavy trailers and semi-trailers; alongside this pattern stand OP 1000 and the special version OP 1F 2F 22.5 as separate types.

The register lists here 8 versions with unladen weights from 7,320 to 12,210 kg at a gross weight of 32,000 to 47,000 kg. Lengths range from 9,400 to 10,960 mm, and widths from 2,470 to 2,550 mm.
With gross weights up to 47 tonnes and lengths of around 9 to 11 metres, the OP range sits in the class of multi-axle trailers and semi-trailers for European road freight, as used in long-haul transport behind tractor units or as trailers in drawbar combinations.
When buying a used trailer of this weight class, check the frame and chassis rails for corrosion and cracks, the condition of the axles and suspension, the operation of the braking system including lines and connections, and the tyres in the 22.5-inch size. Wear parts such as axles, brake linings and lighting are available through the general commercial-vehicle parts trade, brand-specific parts only to a limited extent. It is also worth checking the condition of the type plate and any signs of structural modification.

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.
