New DX27Z-7 and DX35Z-7 from Doosan

Published 4/7 at 08:38

Doosan Infracore Europe has announced the launch of the new DX27Z-7 2.8t and DX35Z-7 3.9t Stage V compliant mini excavators. Both new models provide a larger working range than the previous generation machines, together with higher lifting capacities and digging forces.

An important feature of the new Doosan mini excavator range is the installation as standard of the latest version 3.0 of the ‘DoosanConnect’ system, which provides a telematics management system for the excavators by collecting data from sensors on the machines. The DX27Z-7 and DX35Z-7 are now the smallest machines in the Doosan range with this system. The models also include the new shared global styling for the next generation Doosan mini excavator range. The zero tail swing design of both machines make them ideal for work in confined spaces on construction, landscaping and utility projects.

Both models are powered by the Doosan D17 Stage V compliant diesel engine providing 18kW of power at 2,400 and 2,200rpm respectively for the DX27Z-7 and DX35Z-7. They also offer high auxiliary flows of 58 and 74 l/min, respectively, to enhance work with attachments. Newly designed cast counterweights ensure machine balance and stability when working. Long arm options are available for both models with 60kg and 100 kg additional counterweights, respectively.

Visibility and workability are improved by increasing the bucket protrusion distance beyond the tracks. Placing the boom swing cylinder on the left hand side of cab allows the operator to work right up against walls and other structures on the right hand side of the machines. The fuel tank and boom swing cylinder have been positioned at the base of the cab.

The excavators incorporate a new dozer blade providing both a high dozer lifting height and dozer digging depth. The machines also have a new dozer blade control lever. Using the dozer lever, the operator can select between low and high speed for the levelling blade hydraulics. Travel speed can also be selected by using the travel selector button on the dozer lever. When hydraulic oil pressure rises due to going up a slope while driving in the high speed mode, the travel speed auto shift valve automatically resets the travel speed to low, to enhance the operator’s driving convenience and to reduce machine stress.

As well as high performance, versatility, durability and ease of maintenance, the excavators feature a new larger, roomier cab, providing excellent operator comfort and controllability.  A new high comfort cab has a full glass entry door to maximise operator visibility on this side of the machine from inside the cab. The high luminance LED work lamps on the cab further enhance visibility and additional LED lamps are also available as an option. The enhanced heating/HVAC system provides more nozzles to direct warming and cooling air, including both front and rear pillar nozzles that together help to improve the system performance.
