Douglas Equipment Ltd based in Cheltenham England, started building heavy tractors (trucks) in 1947. They are now a subsidiary of the Dennis Group plc.
The firm introduced the four-wheel drive Transporter model after the war in 1947 , based on an AEC Matador built from 1939-1945 as an artillery tractor. The Douglas truck had a 125 bhp AEC diesel engine of 9.6 litre (588 cu in).
The firm also built a range of industrial tug trucks for trailer haulage in factories, ports and docks loading ships. The Douglas Tugmaster was introduced in the early 1950's, with a new model for the Ro-Ro ships in 1955 called the Douglas Tugmaster Ro-Ro.
Douglas continues today as part of the Dennis Group. They are builders of heavy duty container handling tugs.
