The register lists 63 versions with kerb weights from 700 to 3,500 kg and gross weights from 920 to 3,500 kg. Lengths range from 4,920 to 9,600 mm, widths from 1,270 to 2,300 mm.

Trailer cranes of this type are used by roofers, façade contractors and material-transport firms to lift building materials or components onto roofs and scaffolding without needing a dedicated mobile crane. Their compact build, mounted on a car-trailer chassis, makes them affordable and flexible for smaller firms. As braked class O2 trailers up to 3.5 t gross weight, they can be towed behind any suitable vehicle with a tow hitch and a category BE licence.

When buying used, check the jib sections and cable routing for wear, the hydraulic rams for leaks, and the frame for cracks at the support points. Stability on the outriggers, the trailer's brake system, and an up-to-date crane inspection certificate should all be checked. Spare parts for cables, hydraulics and the jib are supplied directly by the manufacturer.
