HAMMELMANN Other models

The register lists 14 versions with unladen weights from 1,980 to 2,702 kg, gross weights from 2,000 to 3,000 kg, lengths from 3,930 to 4,690 mm and widths from 1,800 to 1,980 mm.

The small gap between unladen and gross weight is typical of these trailers: the weight of the fixed pump, drive and water tank makes up most of the permitted load, leaving little free payload beyond it. Such trailers are used in sewer cleaning, construction and industry, where high-pressure water jets remove deposits, coatings or concrete. Operators are mainly specialist pipe and sewer cleaning firms as well as construction companies that keep the trailers as a mobile work unit.

On a used trailer, the condition of the pump and its seals, the drive and hydraulics, axle and brake, rust on the frame, and the tightness of the water tank and hose lines all count; the pump's operating hours say more than the age of the chassis alone. Pressure gauges, safety valves and the record of the last service should also be checked before purchase.
