Heathfield Engineering Limited 1965-1999
Heathfield was a UK brand of Dumptruck that was founded in the mid 1960s and the main models were built at Newton Abbot in Devon, England . They were taken over by Bell of South Africa in 1998 after having several other owners and eventually closed down. This manufacturer was very resourceful using several parts from many mechanical components sourced from outside companies. With a wide choice production output was very good in the 1970s and 1980s. One of the many successful British dumptrucks manufactures of its time.
The company was founded by the engineering firm of "Centrax Power Units Ltd" a heavyduty axle specialist for all kinds of machines that used wheels. Centrax built Axles and Gearboxes under licence from Rockwell and supplied them to companies such as Allis-Chalmers, Aveling-Barford, and JCB in the UK. Later on the company was renamed as Heathfield Engineering Ltd and this was their new name their models were marketed.
In 1978 a 6x4 rigid was built as the H2200 with a 20 ton payload and powered by a Cummins VT555 220 hp engine and a 5-speed Allison transmission, but sales were slow and it was dropped. But was replaced by other faster selling updated models that took its place.
In 1983 the Heathfield Engineering company was bought by the management from parent co "Centrax". New larger versions the H44 and H50 were designed. From the 1980s onwards all models used independent suspension allround and wide oneman halfcabs.
In 1991 they were taken over by Unipower who had also acquired Haulamatic. Assembly moved to Tipton in the West Midlands. Alvis then bought Unipower for the military vehicle lines and sold Heathfield Haulamatic Ltd off to LH Group Plant Ltd of Burton on Trent. LH Group plant were UK agents for Bell of South Africa. LH dropped the smaller models and concentrated on the H33 and H44. Bell then bought out LH Group' Dumper truck operations in 1998 and dropped the rigid dump truck models.

Within these zones are a lot of quarries and mines that are still resourceful where one is very likely to find a Heathfield usually joined by a Aveling Barford, a DJB, a JCB, a Haulamatic and a Foden which is probably with Leyland are the best known of all.
