23 Jul 13 Doosan has launched a pair of six-tonne compact excavators with up to 10% more digging power than the models they replace.

The new DX62R-3 reduced tail swing (RTS) and DX63-3 conventional tail swing models replace the DX60R and DX55E machines.   

Hydraulic performance has been boosted with a 33% increase in maximum flow rate to 132 litres/min. The hydraulic system now has a load sensing system for improved combined operations. Two-way auxiliary hydraulic flow is also available for the primary auxiliary circuit for operating high-flow attachments.   

The bucket digging force is now 4.4 tonne, 7% above the previous models and the arm digging force is 10% higher at 2.9 tonne.  The arm is also longer than before for a better overall working range. 

Traction force has been increased by 5% to 5.6 tonne and travel speeds have been increased in both the low range (2.6km/h) and the high range (4.7km/h).

There is a new colour 150mm LCD monitor that allows operators to control auxiliary flow and to monitor functions such as service periods. Anti-theft protection is standard via a password lock-out system. 

The DX62R-3 and the DX63-3 models are powered by the Stage IIIA compliant 36.2kW liquid-cooled Yanmar 4TNV94L diesel engine running at a maximum speed of 2200rpm. Auto idle helps reduce fuel consumption.
