The Thwaites company based in Warwickshire, England is best known as a dumper truck manufacturer. the company was founded by Basil Thwaites in 1937 as an Agricultural Engineering company. Basil Thwaites was from the Yorkshire brewing family.

History Edit

Founded in 1937 as "Thwaites Agricultural Engineering" company, in Cubbington. They built a wide range of machinery, Milking machines, Trailers and Forage harvesters over the years. In 1943 he invented a high speed tractor, with a 24 hp Ford TVO engine.

The first machine for construction was a Brick Elevator (mechanical hod carrier) built in the late 1940's. The first Dumper was a 3 wheeled machine, powered by a 6hp single cylinder Petter engine, driving by a 3 speed gearbox. The skip was a 10 cu ft capacity of wet concrete or 15 cwt (750 kg). This was followed by a 4 wheel version in 1953. In 1954 the company name was changed to "Thwaites Engineering Ltd", and the agricultural products dropped. The Multi-Skip was a inter changeable skip carrier.

Various other models followed, with the "Tusker", a multi-purpose chaisse, with removable skips and the ability to fit a backhoe attachment. In 1962 the 4 wd "Alldrive" was introducing with a 2 ton capacity, claimed to "go were other dumper can not go". This was followed by a 3 ton machine in 1965, and which was then followed with the 5 ton capacity "Goliath" in 1974.

The range was updated with the 2 ton Alldrive becoming the "Alldrive 4000" The new 8 ton model of the "Goliath" raising capacity to a new level for site dumpers in the early 1980s.

1986 saw the introduction of the compact "Alldig" backhoe loader. By the 1980s they had introduce Torque-converter transmissions with shuttle reverse for most of the range. In the mid 1990's the range was updated, with new higher capacity machines.

Around the late seventies / early eighties Thwaites Engineering built a prototype Telescopic Handler, but they never went into production with it.^{[citation (source) needed]} Do any photos exist of this machine ?
