Draco ASS 321 – specifications

The register lists here 8 versions with unladen weights from 5,790 to 7,540 kg, gross weights from 16,000 to 30,000 kg, a width of 2,550 mm and a recorded length of around 8,800 mm.

Low-loader trailers of this weight class carry construction machinery, agricultural machinery and other bulky loads and are, in the Netherlands and the neighbouring European market, a regular part of the fleet of hauliers, machinery hire firms and construction companies; there they complement the offering of the larger European low-loader makers in the mid weight segment. Transport on public roads at these weights and widths requires, depending on the country, special permits or escort vehicles, which concentrates use chiefly among specialist heavy-haulage firms.

Buying used, the condition of the frame and axles, the function of the ramps and hydraulic lowering, the brake system and hitch coupling, and rust on load-bearing parts all count; wear parts such as axles, brakes and lighting are available through the general commercial-vehicle parts trade. It is also worth comparing the type plate and chassis number against the vehicle documents and checking the tyres for even wear, since one-sided wear points to axle damage.
