New Doosan products on show at Plantworx

Several new Heavy products not previously seen in UK will be the highlight of the Doosan stands

DOOSAN are aiming to show the new Stage IIIB-compliant DX140W-3 wheeled excavator and DL300-3 wheel loader (pictured) as part of the company’s static display, and the new Stage IIIB DX300LC-3 crawler excavator in the Doosan demonstration area in the Dig Zone at Plantworx.

Like all Doosan Stage IIIB-compliant models, these products are said to go much further than simply meeting the emission regulations – they offer a substantial boost in performance compared to the previous generation machines.

The new DX140W-3 wheeled excavator is powered by the reliable Doosan DL06KB 6-cylinder ‘common-rail’ turbocharged diesel engine providing a 2% increase in power to 102kW (137hp) at 2,000 rev/min and a 12% increase in engine torque compared to the previous DX140W model.

The DX140W-3 model provides new levels of comfort, ease of handling, optimum balance and high mobility for multi-tasking as a tool carrier for buckets, breakers, pallet forks, grabs and crushers for excavating, handling, carrying and other applications.

The new wheeled excavator is well suited to small-to-medium sites in civil engineering, utility and road projects, for applications such as digging trenches; breaking into rock, concrete and asphalt surfaces; setting up trench boxes; levelling; lifting pipes; moving pallets/materials; and loading trucks.

Showing its paces in the Dig Zone demonstration area at Plantworx, the DX300LC-3 crawler excavator is powered by the Doosan DL08K ‘common-rail’ 6-cylinder turbocharged diesel engine. At 159kW, the Doosan DL08K engine in the DX300LC-3 excavator delivers 2% more power at a lower speed of 1,800 rev/min than the existing DX300LC Stage IIIA model.  Field tests show a 5 to 10% reduction in fuel consumption, depending on the operating mode selected and the work being done.

Workload/hour outputs have increased by an average of 6% across the different power modes in the DX300LC-3. In addition, a new travel device has increased the maximum travel speed to 5.3km/h, while the drawbar pull is increased by 4% to 29,800kg and lifting capacities have been increased by 6%.

The new DL300-3 wheel loader is powered by the 9-litre Scania DC9 5-cylinder diesel engine delivering a maximum power output of 202kW at 1,800 rev/min and meeting Stage IIIB emission regulations through the use of SCR (selective catalytic reduction) technology.

The smallest model in the new family of large wheel loaders from Doosan, the new DL300-3 combines its high engine power output and SCR technology with a new ZF five-speed transmission, which improves the transfer of power from the engine to the wheels and contributes significantly to the overall reduction in fuel consumption.

All new generation Doosan large wheel loaders are equipped with a torque converter cut-off system which, when activated, switches on automatically. This provides a direct mechanical connection between the engine and transmission without loss of power and torque by the torque converter. Tests have shown that fuel consumption is reduced by as much as 10% with increased traction compared with conventional systems.
