Lyndon Thomas, based in Northampton, has taken delivery of eight Doosan DA30-5 articulated dump trucks (ADTs). The firm offers a range of services across the country including earthmoving, contract crushing and screening, demolition and distribution of all types of aggregate.
The Doosan Stage IV trucks were purchased along with a Doosan 30-tonne DX300LC-5 Stage IV crawler excavator from dealer Murley Construction, based in Stourport-on-Severn.
The order was placed based on the performance of an DA30 ADT demo machine on a range of works including the preparation of a new landfill cell under difficult conditions, where the machine outperformed other brands in every aspect from traction to productivity.
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. Along with a free-swinging rear tandem bogie, it ensures equal distribution of weight to each wheel and guarantees permanent six-wheel contact and drive for equal power distribution and high performance on difficult terrain.
The DX300LC-5 is powered by a Scania DC9 five-cylinder diesel engine, with an output of 202kW of power at 1,800rpm, providing a 27% increase in engine power and a 30% boost in torque over earlier models.
Owner Lyndon Thomas said: “More than a dozen of our operators worked the Doosan ADT very hard during the four to five-week demo, and they were all impressed with the traction, power and general performance.
“Reliability was also very good as our operators pushed the machine to its limits – I think this is a facet of the rugged simplicity of Doosan’s design, which means less can go wrong. The DX300LC-5 excavator has also performed excellently.”
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.
