Lyndon Thomas plumps for Doosan

Lyndon Thomas Limited, based in Northampton in the UK, has 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 offers 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, the Doosan dealer for the West Midlands, Worcestershire, Warwickshire, Shropshire, Herefordshire, Staffordshire, Northamptonshire, Leicestershire and Cambridgeshire.

The new order for Doosan ADTs confirms Lyndon Thomas as the owner of the largest fleet of dump trucks in the East Midlands area. The order was placed based on the excellent performance of a Doosan DA30 ADT demonstration machine on a range of works including the preparation of a new landfill cell in very difficult conditions, where the Doosan machine outperformed the other brands on site in every aspect from traction to productivity.

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 ensures equal distribution of weight to each wheel and guarantees permanent 6-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 results in ‘best in class’ rough and soft terrain capabilities and avoids the need for electronic aids such as traction control.

Company Owner, Lyndon Thomas, said: “The climb rate of the Doosan demo machine was far superior to that of the ADTs from Volvo and that was with a tailgate which was not on the other machines. More than a dozen of our operators worked the Doosan ADT very hard over the 4-5 weeks we had the machine and they were all impressed with the traction, power and general performance available.

“Reliability was also very good as our operators tried to push the machine to its limits – I think this is a facet of the rugged simplicity of the Doosan ADT design which means less can go wrong. The same can be said of the new Doosan DX300LC-5 excavator which we have bought and which has also performed excellently. As well as our staff and customers, other earthmoving companies are now aware of the high performance offered by Doosan construction machinery which can only bode well for the brand in the future.”

Like all of Doosan’s new Stage IV/Tier 4 Final machines, the designs of the DA30-5 ADT and DX300LC-5 go far 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.

The ‘best-in-class’ fuel consumption of Doosan 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. When this is coupled with the enhanced rear differential system which reduces engine rpm and further increases machine durability, customers are ensured of an improved cost per tonne carried with the Doosan ADT range.

The Doosan DA30-5 is powered by the Scania DC9 276 kW (370 HP) diesel engine, meeting 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 trucks. 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 is also powered by the Scania DC9 5-cylinder diesel engine, with an output of 202 kW of power at 1800 rpm, providing a huge 27% increase in engine power and a massive 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 huge reductions in fuel consumption compared to the Stage IIIB machine.
