The Dennis DF series was a range of heavy-duty fire engine chassis produced by Hestair Dennis (later Dennis Specialist Vehicles) from 1979 to the early 1990s. Based on the Dennis RS/SS series, the DF has a 16,260 kg (35,850 lb) gross vehicle weight, and was produced primarily as a base for turntable ladder appliances or tanker units carrying either foam or water.[2]

The DF could be offered in 'Firebird' or 'Waterbird' specification. The 'Firebird' variant could carry up to 1,000 imp gal (4,500 L; 1,200 US gal) of water, while the 'Waterbird' variant could carry 1,800 imp gal (8,200 L; 2,200 US gal) of water.[1]

Operators

Turntable ladder appliances on the Dennis DF chassis were sold to a number of fire brigades in the United Kingdom, including the Tyne and Wear Metropolitan Fire Brigade.[3]

The DF was also sold to fire brigades in Hong Kong, the Middle East and Kenya.[1] DF135s were also exported to New Zealand for use as pump tenders in the New Zealand Fire Service, with some being built with Mills-Tui bodywork.[4][5]
