New Doosan equipment at Bauma 2013

Doosan Construction Equipment will be showing a wide range of new excavators, wheel loaders, articulated dump trucks and attachments for the first time at Bauma 2013 in Munich, Germany from 15-21 April 2013.  Among the new products on the stand are the DX140W-3 and DX160W-3 wheeled excavators, the DX380LC-3 large crawler excavator and the DL200-3, DL250-3 and DL550-3 wheel loaders. The company states: “Going well beyond meeting the latest emission requirements, all new Doosan Stage IIIB compliant excavators, wheel loaders and articulated dump trucks have been designed to exceed customer requirements for quality, productivity, controllability, comfort, reliability and durability, with greatly reduced overall costs and optimal fuel efficiency.”

 The new DX140W-3 and DX160W-3 excavators are both powered by the reliable Doosan DL06KB 6-cylinder ‘common rail’ turbocharged diesel engine providing a 2% increase in power to 102 kW at 2,000 rpm and a 12% increase in engine torque.  The new DX380LC-3 excavator is powered by the larger Doosan DL08K diesel engine delivering an 8% increase in torque and 5% more power (213 kW) at a 6% lower rpm of 1,800. In all three models, the engines meet Stage IIIB engine emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies.

 The new wheeled excavators offer a substantial boost in performance compared to the previous generation machines:

  • Main pump flow has increased by 8% and system pressure has risen to 350-370 kg/cm2
  • Bucket forces increased by 16% and arm forces by 6-16%
  • Lifting capacities increased from 3-12% over the front of the excavators
  • A 10% increase in traction force
  • Up to 9% reduction in fuel consumption
  • In-cab noise levels reduced by 5 dBA

 Similarly, the new DX380LC-3 large crawler excavator offers “outstanding performance levels and exceptional fuel efficiency” compared to other machines in the 34 to 42 t market segment, states Doosan.  A new joggle/shuttle control is an exclusive feature on new generation Doosan excavators.  Other highlights include: 

  • Up to 22% increase in productivity (m3) to fuel consumption (l) ratio
  • 23% more pump flow
  • 40 t plus class size undercarriage for optimum stability
  • A 15% increase in drawbar pull
  • A 15% increase in front lifting capacity

 As well as offering more standard features than other excavators of its size on the market, there is a greatly expanded choice of options for the DX380LC-3, including a new narrow (3 m) undercarriage which will be shown at Bauma 2013 and a new two-mode floating boom system.

On the new wheel loaders, the company states: “With bucket capacities of 2.0, 2.5 and 5.4 m3, respectively, the new DL200-3, DL250-3 and DL550-3 wheel loaders are intended to meet a wide range of material-handling needs from loading and transporting granular material to industrial, mining and quarrying applications.  These new generation models combine high engine power with a number of new features to minimise fuel consumption and provide better operator comfort, exceptional performance, ease of handling, easier serviceability and extended durability.”
