Fruehauf ONCRK – semi-trailers from 22 to 39 t gross weight: the type series from the inventor of the semi-trailer, up to 14 m long
Fruehauf is credited with inventing the semi-trailer: in 1914 August Fruehauf built the first trailer in Detroit to be towed by a motor vehicle instead of horses, founding an entirely new vehicle class. The ONCRK series states the gross weight in tonnes within its type number – ONCRK 22-110 stands for 22 t, ONCRK 39-327 for the heaviest version in the register at 39 t.

The register lists 8 versions here with unladen weights from 7,750 to 9,810 kg and gross weights from 22,000 to 39,000 kg. Lengths range from 11,600 to 14,000 mm, widths from 2,550 to 2,600 mm.
As a descendant of the first semi-trailer, the ONCRK series represents classic European long-haul semi-trailer transport, in which Fruehauf ranked among the defining brands for decades alongside makers such as Fliegl and Schmitz Cargobull.
When buying one of these older chassis, check the frame and main beams particularly carefully for corrosion and cracks, as well as the axle assemblies, suspension and brake system with its connections. The kingpin and the wear plates of the bearing surface also belong on the checklist; spare parts for this era are generally only available through specialist commercial-vehicle workshops. Assessing the condition of the tyres and wheels also forms part of the basic inspection for these historic chassis.

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.
