Bunk BU: the low-loader trailer line for construction machinery, type designation by gross weight from BU 3,500 to BU 20,000, 940 to 5,980 kg kerb weight, 3,500 to 28,000 kg gross weight
The BU line is a type range from the German manufacturer Bunk, which builds low-loader trailers for hauling construction machinery and working equipment. The type designation follows a clear logic: the code BU is followed by a three- to five-digit number giving the gross weight in kilograms, from BU 1000 through BU 3500 and BU 10000 up to BU 20000 and BU 28000, supplemented by additions such as ZW for twin tyres or T for certain frame variants.

The register lists 48 versions here with a kerb weight of 940 to 5,980 kg and a gross weight of 3,500 to 28,000 kg. Widths range from 1,890 to 2,600 mm, lengths from 5,860 to 12,820 mm.
With a gross weight of up to 28 tonnes, the BU line runs from light O3-class trailers to heavy O4-class low-loaders, of the kind needed to move excavators, wheel loaders and other construction machinery between sites. Such low-loaders are common among construction firms, plant-hire companies and in earthworks.
When buying a used low-loader trailer, check the load platform for distortion and cracks caused by point loads from wheels, and check the ramps, locks and lashing eyes for correct function. Axles, the braking system and the frame should be checked especially carefully for rust and wear given the high loads carried; parts for axles and braking systems are available from commercial-vehicle and trailer dealers.

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.
