With the introduction of the 10 new models listed below, full details of which are available in this press pack, Doosan has completed the launch of the company’s new medium-sized ‘DX-7’ range of 17 Stage V crawler and wheeled excavator models from 14 to 25 tonne.  

– DX140LC-7, DX140LCR-7 and DX160HT-7 14-16 t Crawler Excavators

– DX235LC-7, DX235LCR-7 and DX255LC-7 23-25 t Crawler Excavators

– DX165WR-7 17 t Wheeled Excavator

– DX170W-7, DX190W-7 and DX210W-7 18-22 t Wheeled Excavators

To recap, Doosan has already launched in the last six months the first seven models in the DX-7 medium-sized Stage V range, namely the:

– DX225LC-7 23 t Crawler Excavator 

– DX140W-7 and DX160W-7 16 t Wheeled Excavators 

– DX245NHD-7 25 t Crawler Excavator (New range addition)

– DX210-7, DX210NLC-7 and DX210LC-7 21 t Crawler Excavators (New range addition)

The process began with the DX225LC-7, the first in this size range to feature Doosan’s high performance and fuel-saving D-ECOPOWER virtual bleed off (VBO) technology. Altogether, the new medium-sized DX-7 models provide significantly higher performance in every area than the previous generation Stage IV machines. 

They combine enhanced comfort, increased tool carrier capability and novel operator assist technology, with new features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, robustness and agility. Maintenance of the diesel particulate filter (DPF) has also been greatly reduced, with no maintenance required until the machine has operated for 8000 hours.

In summary, all DX-7 medium-sized machines share a host of innovative new features including: 

  • New State-of-the-art High Comfort Cab
  • New Tiltrotator Mode 
  • New Heavier Standard and Optional Counterweights
  • New Enhanced Tool Carrier Capability
  •     New Smart Hydraulic System
  •     New Fine Swing Function
  •     New Lifting Eye
