Biggest ever UK order for Doosan trucks

Doosan DA30-5 articulated dumptruck

Northampton-based Lyndon Thomas take delivery of eight new DA30-5 articulated dumptrucks

LYNDON Thomas Ltd, based in Northampton, have taken delivery of eight new Doosan DA30-5 articulated dump trucks (ADTs), the biggest single order for Doosan trucks in the UK, for use in projects across the country.

Established in 2010, Lyndon Thomas offer a range of services including earthmoving, contract crushing and screening, plant hire, demolition and distribution of all types of aggregate.


The new Doosan Stage IV trucks were purchased along with a new Doosan 30-tonne DX300LC-5 Stage IV crawler excavator from Murley Construction, Doosan dealers for the West Midlands, Worcestershire, Warwickshire, Shropshire, Herefordshire, Staffordshire, Northamptonshire, Leicestershire and Cambridgeshire.

The new order for the ADTs confirms Lyndon Thomas as owners of the largest fleet of Doosan dumptrucks in the East Midlands area.

Like all Doosan ADTs, the DA30-5 features an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulation. This together with a free-swinging rear tandem bogie, is said to ensure equal distribution of weight to each wheel and guarantees permanent six-wheel contact and drive for equal power distribution and excellent performance on difficult terrain.

Collectively, the forward turning point, the unique tandem bogie and the sloping rear frame are said to result in ‘best in class’ rough and soft terrain capabilities and avoid the need for electronic aids such as traction control.

Like all of Doosan’s new Stage IV/Tier 4 Final machines, the designs of the DA30-5 ADT and DX300LC-5 also go beyond just meeting the latest emission standards and incorporate many additional features and product improvements to establish a new benchmark in performance, fuel efficiency, enhanced controllability and high operator comfort, together with improved reliability, durability and reduced maintenance and servicing costs.

Doosan say the ‘best-in-class’ fuel consumption of their ADTs is down to a combination of features including a new Scania diesel engine and a ZF EP transmission, improving the transfer of power from the engine to the wheels for outstanding traction. They add that when this is coupled with the enhanced rear differential system, which reduces engine rev/min and further increases machine durability, customers are ensured of an improved cost per tonne carried with the Doosan ADT range.

The Doosan DA30-5 ADT is powered by the 276kW (370hp) Scania DC9 diesel engine, which meets the Stage IV/Tier 4 Final emission regulations through the use of both selective catalytic reduction (SCR) and exhaust gas recirculation (EGR) technologies, with an electronic engine brake system, one of four brake systems on the truck. Doosan’s Stage IV/Tier 4 Final ADTs do not need a diesel particle filter (DPF) to meet the emission regulations.

The new DX300LC-5 excavator is also powered by the Scania DC9 5-cylinder diesel engine, with an output of 202kW of power at 1,800 rev/min, providing a 27% increase in engine power and a 30% boost in torque over the previous LC-3 model. As well as the Scania engine, new innovative and exclusive features have been introduced, leading to significant reductions in fuel consumption compared with the Stage IIIB machine.
