On display on the Doosan stand was the new version of the Doosan DX530LC-7 53-tonne crawler excavator. Next to the stand in the Quarry Face Demo Area, a DX420LC-7 43.5-tonne crawler excavator continued to load a Doosan DA30-7 articulated dump truck (ADT) throughout the show.
A series of humps created in this area by Doosan served to replicate the off-road advantages offered by the unique free-swinging rear tandem bogie in the company’s ADTs, which guarantees permanent six-wheel contact and drive, particularly for the most difficult terrains and working conditions.
Some new standard and optional features are now available on several of the large Doosan crawler excavators, including the DX300LC-7, DX350LC-7, DX380LC-7 and DX490LC-7 models, as well as the DX420LC-7 and DX530LC-7 excavators presented at Hillhead. The main changes are in the new cab, which takes operator comfort and ease of operation to the next level.
Also on display on the Hillhead stand was the DA45-7, the largest model in the Doosan ADT range and the DL420-7, part of the award-winning DL-7 range of wheeled loaders from Doosan.
Another of the new products being shown by Doosan for the first time at Hillhead 2022 was the 24.3 tonne DX235LCR-7 reduced radius crawler excavator. The DX235LCR-7 is part of Doosan’s new medium-sized ‘DX-7’ range of 17 Stage V crawler and wheeled excavator models from 14 to 25 tonnes.
Doosan also introduced several new compact products at Hillhead, including the new DX100W-7 10.7 tonne wheeled excavator, the new DX27Z-7 and DX50Z-7 next-generation mini-excavators and the first appearance of the DL80TL-7 model from Doosan’s new range of compact wheeled loaders.
Like all the new DX-7 medium-sized excavators, the DX235LCR-7 combines enhanced comfort, increased tool carrier capability and novel operator assist technology with new features to boost fuel efficiency, uptime and return on investment, and 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.
