Northfield Industrial Fabrications Ltd (NIF) was founded in the late 1940s at Ossett, West Yorkshire England.


Company HistoryEdit

Northfield Industrial Fabrications Ltd (NIF) was started in the 1940s and were actually makers of dumptrailers, cargotrailers and other heavy trailer types for the UK Agriculture, Construction and Mining industries to handle all kinds of general cargo and large specialised freights. Then in the late 1950s the firm developed and  invented their first own original vehicle called the new ADT. These brand-new Northfield F-Series were the ancestors and forerunners of today´s modern looking ADTs and their first  Northfield models of the 1950s were powered by standard tractor diesel engine usually a modified Fordson  mounted over the front axle with front wheel drive, had power steering, fitted with equal tractor tyres and a oneman enclosed drivers cab. Later on alternative updated running gear was available for the larger models. The Northfield company were slowly to became one of the early builders of off-highway dumptrucks in England joining other longer established existing makes such as Aveling-Barford, DJB, Heathfield and Thornycroft to name a few domestic manufacturers.

Just like Camill and Whitlock, Northfield were one of the first British developers and manufacturers of the two axled tractor-trailer haulier designed as a single purpose integrated unit with 180 Degree articulation activated by two pairs of hydraulic rams built on every Northfield F-Series, their trucks were usually powered by famed and durable Ford Diesel 6-cylinder or Perkins Diesel 4-cylinder and later Straigh-six engines. These were available in a small model range of only four different but original ADT models called the F7, the F9 soon joined by the heavier F12 and the F14. Unfortunately NIF LTD production was ended in the 1970s with around 500-600 or so dumptrucks models are reputed to have been assembled and made in total as they could no longer compete together with much bigger specialists of similar vehicles that dominated the UK market at that time.


Northfield Dumptrucks were mainly ADT models which were made from the 1960s to the 1970 by a small mechanical engineering firm called NIF Limited also known as Northfield Industrial Fabrications Ltd based at Ossett in West Yorkshire, England. At that time during the 1960s and 1970s many other UK specialist machinery builders and engineering firms also developed, built and made many prototypes and roadworthy Articulated Dump Truck models all of them pioneering the new ADT layout a recent and latest concept of construction trucks that was found to offer improved traction over tractor and trailer or the conventional rigid dump truck for use on and off road usually seen in construction sites, ore mines,  quarries and many sold for roadbuilding.

The fashion of British made new ADT Concept was a tremendous success because they could bend in the middle when driven and many future earthmover manufacturers would produce very similar machines often in 4X4 and 6WD forms using TD and TDI modern running gear.

The Northfield Original Model Range Edit

Classic Dumptrucks

  • Northfield F7 - A 12 ton fully articulated dumptruck with Perkins P4D 4-cylinder engine and automatic 5 speed transmission many worked as mining trucks. Some were also fitted with the Ford Diesel Engine as used on the successful Ford Custom Class trucks at the time.
  • Northfield F9 - A heavier 14 ton ADT larger than the F7 with Ford 3600 6-cylinder Diesel engine and Ford 6 speed manual gearbox popular as a mining dumptruck as well as a quarry truck. Several were powered by a more powerful Perkins P6 Diesel straight-six for heavy work. 
  • Northfield F12 - A 20 ton ADT larger and heavier new model with Ford 3600 Diesel 6-cylinder engine and a new farmtractor Ford 6 speed manual transmission. Alternatively the same Perkins P6D engine was also available with better torque.
  • Northfield F14 - A 25 ton prototype large ADT that had Ford 4WD Tractor axles and mechanicals with a choice of the more powerful Perkins P6D engine which were known for reliability and ruggedness until in the 1970s also a Perkins V8 Diesel model was also offered but was never produced in large numbers.
