Fruehauf ONCZ – semi-trailer range from the inventor of the semi-trailer: 7 versions, unladen weight from 6,840 to 22,480 kg, gross weight from 30,000 to 42,000 kg, lengths up to 14.8 metres
Fruehauf traces back to August Fruehauf, who in 1914 in Detroit developed the coupling of a towing vehicle with a load-bearing trailer – the invention of the semi-trailer, after which the company is named. The model names of the ONCZ range combine the code ONCZ with two numbers separated by a hyphen or a slash and the suffix A, the first number ranging between 30 and 42 and the second between 218 and 330.

The register lists here 7 versions with unladen weights from 6,840 to 22,480 kg at a gross weight of 30,000 to 42,000 kg. Lengths range from 13,300 to 14,800 mm, and widths from 2,500 to 2,550 mm.
With lengths of up to 14.8 metres and gross weights up to 42 tonnes, the ONCZ range corresponds to classic long semi-trailers for European long-haul transport, as built under the Fruehauf name for decades in several European countries; the wide span of unladen weights points to different bodies, from a simple flatbed to a heavier box body.
When buying a used semi-trailer of this generation, check the frame and chassis rails for corrosion and deformation, the condition of the axles and braking system, the kingpin and landing legs, and the tightness of the tarpaulin or body. Brand-specific parts for the historic Fruehauf semi-trailers are only available to a limited extent, while common axle and brake components can be sourced through the general parts trade.

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.
