Doosan took the opportunity to demonstrate and display the very latest products from the company for the quarrying, mining and construction industries for the first time at the Hillhead 2022 exhibition.
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, that guarantees permanent 6-wheel contact and drive, particularly for the most difficult terrains and working conditions.
Increased Comfort and Controllability A number of 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 wheel 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 a number of 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 wheel loaders.
The New DX-7 Medium-sized Excavators 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, 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.
New High Performance 10.7 tonne Wheeled Excavator Also featuring a new look design, the DX100W-7 10.7 tonne wheeled excavator from Doosan made its debut at Hillhead. The 10 tonne weight class represented by the DX100W-7 is new to the Doosan range and the DX100W-7 offers a high performance solution for customers looking for a wheeled excavator designed primarily for urban and road maintenance applications.
For this type of work, the DX100W-7 offers the best compromise between compactness and agility, complemented by excellent productivity and high-end comfort. It is very important that this type of machine can operate in very restricted areas, so the DX100W-7 can be equipped with the option of four wheel steering and a crabbing mode, with two wheel steering as standard.
Next Generation Doosan Mini-Excavators The new DX27Z-7 2.8 tonne and DX50Z-7 5.4 tonne models on the Hillhead stand provided the first look at Doosan’s next-generation Stage V compliant mini-excavator range, which also includes the DX35Z-7 3.9 tonne and DX55R-7 5.7 tonne models.
The zero tail swing design of the DX27Z-7 and DX50Z-7 make them ideal for confined space work. The DX27Z-7 is powered by the Doosan D17 Stage V compliant diesel engine providing 18.4 kW (24.7 HP) of power at 2400 RPM. The DX50Z-7 is powered by the Doosan D18 Stage V compliant diesel engine providing 36.4 kW (48.8 HP) of power at 2200 RPM. As a result, both models offer the highest power and torque in their respective classes and cover a wide range of applications including heavy duty work.
New Compact Wheel Loaders As represented by the DL80TL-7 model on the Hillhead stand, Doosan is now offering a choice of five new compact wheel loader models, including the DL60-7, DL65-7, DL80-7 and DL85-7 models, with operating weights from 3500 to 5000 kg. Just like their much heavier versions in the Doosan range, these new compact wheel loaders set the industry standard for productivity, flexibility, comfort, safety and reliability, with powerful Stage V engines, hydrostatic 4-wheel drive, 100% differential lock on both axles and versatile and powerful hydraulics.
