Bockmann car trailers up to 3.5 t (class O2) – the current range of the Lastrup maker since 1956: AB, AT, ALT and ATH, 410 versions, kerb weight 170 to 2,720 kg
Böckmann Fahrzeugwerke, based in Lastrup in the Cloppenburg district, trace back to a village smithy founded by Anton Böckmann in 1956; cattle-trailer production began in 1958, and from 1960 the first horse trailers were built from them. Over 70 years the firm has, by its own account, built more than a million trailers. This page, listed under the spelling "Bockmann" without the umlaut, is a class O2 collective page of current models with a gross weight of 0.75 to 3.5 tonnes, from the AB, AT, ALT and ATH type families to the BMA and BMSA horse-transport ranges; the digit string before the slash, such as 2513, by manufacturer logic denotes the platform dimensions in decimetres (2.50 by 1.30 m), and the number after it the weight class.

The register lists 410 versions with kerb weights from 170 to 2,720 kg, gross weights from 1,000 to 3,500 kg and widths from 1,460 to 2,550 mm; lengths range from 3,320 to 6,960 mm.
Böckmann is among the largest German makers of car and horse trailers, competing with Humbaur and Westfalia, with a range spanning plain load trailers to specially sprung horse transporters for both professional and private animal transport.
When buying used, check the condition and smooth action of the coupling head, whether the overrun brake and its linkage work, the axles and rubber-torsion suspension, frame corrosion at the drawbar and axle mounts, the lighting system, the floor, tarpaulin or partitions, and tyre age; Böckmann maintains a dense German dealer and parts network. On the BMA and BMSA horse-transport versions, it is also worth checking the condition of the floor matting and partition padding, and corrosion on the usually exposed ventilation grilles.

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.
