Increased comfort and controllability

A number of new standard and optional features are now available on several large Doosan crawler excavators, including the DX350LC-7, DX380LC-7, DX420LC-7, DX490LC-7 and DX530LC-7 models. The main changes are in the new cab, which have been made to take operator comfort and ease of operation to the next level. In all the excavators, the main control valve (MCV) has also been changed as standard to a Doosan Mottrol MCV with no change in performance.

Next generation mini excavators

Hillhead provides the first look at selected models from Doosan’s next generation mini excavator range, which currently includes the new DX27Z-7 2.8t, DX35Z-7 3.9t, DX50Z-7 5.4t and DX55R-7 5.7t Stage V compliant models. The zero tail swing design of the DX27Z-7, DX35Z-7 and DX50Z-7 and the reduced radius design of the DX55R-7 models make them ideal for confined space work.  The DX27Z-7 and DX35Z-7 are powered by the Doosan D17 Stage V compliant diesel engine providing 18.4kW of power at 2,400 and 2,200 rpm respectively. The DX50Z-7 and DX55R-7 are powered by the Doosan D18 Stage V compliant diesel engine providing 36.4kW of power at 2,200 rpm. As a result, all four models are able to cover a wide range of applications including heavy duty work. A novel platform design featuring new upper structures has been designed to increase durability/robustness and this is complemented in all four new mini excavators by a larger working range, coupled with higher lifting capacities and digging forces.

New high performance wheeled excavator

Also featuring a new look design, the DX100W-7 10.7t wheeled excavator will make its debut at Hillhead. The 10t 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 what the company says is the best compromise between compactness and agility, complemented by excellent productivity and high end comfort. As it is important for this type of machine to operate in very restricted areas, the DX100W-7 can be equipped with the option of four wheel steering and a crabbing mode, with two wheel steering as standard.

As well as agility in confined spaces, the DX100W-7 has been designed for safe operation. The integral 1.35t counterweight ensures high levels of stability for lifting work in combination with the articulated boom and long arm, which together provide a larger working range. The counterweight also has a novel design, offering easy maintenance access from the rear of the machine and from ground level. Furthermore the articulated boom ensures that the operator is able to position the machine as close as possible to trucks during loading. In addition, the DX100W-7 offers maximised lifting capacities and digging forces, as well as satisfying a requirement in some countries for a wheeled excavator to have a travelling height of below 4m.

New compact wheel loaders

Doosan has signed an exclusive supply agreement with Netherlands based Tobroco-Giant, a leading manufacturer of compact wheel loaders for materials handling, construction, rental, agriculture and landscaping. Under the new agreement, selected compact wheel loader models are being manufactured by Tobroco-Giant in the orange colours of Doosan and being sold under the Doosan name through the brand’s European dealer network. As will be featured on the Doosan Hillhead stand, the partnership covers a total of five new Doosan compact wheel loader models, the DL60, DL65, DL80, DL85 and DL80TL, with operating weights from 3,500 to 5,000kg. Just like their much heavier versions in the Doosan range, these new compact wheel loaders have been designed to for productivity, flexibility, comfort, safety and reliability, with powerful Stage V engines, hydrostatic four wheel drive, 100% differential lock on both axles and versatile and powerful hydraulics.
