The register lists 9 versions with unladen weights from 920 to 1,460 kg, gross weights from 1,000 to 2,700 kg, lengths from 4,230 to 4,620 mm and widths from 1,650 to 2,050 mm.

Such measuring trailers are used by road authorities, engineering firms and road contractors to assess the bearing capacity and condition of pavements before resurfacing or new construction, and are towed behind a vehicle over the road network under test.

When buying used, besides the chassis, axle, brakes and lighting, the calibration of the measuring sensors, the condition of the falling-weight mechanism, and the service and calibration history of the measuring system are worth checking. Alongside the Falling Weight Deflectometer, the suffix HWD denotes a Heavy Weight Deflectometer for testing more heavily loaded surfaces such as airport pavements. Suffixes such as 8002-103 and 8012-019 distinguish variants of the same build size by a further number after the hyphen.
