Doosan’s new 6 tonne compact excavators

Doosan has launched two new generation 6 tonne compact excavators, the new DX62R-3 reduced tail swing (RTS) and DX63-3 conventional tail swing models. Designed as replacements for the existing DX60R and DX55E machines, the new models are said to benefit from a significant improvement in hydraulic performance, through a 33% increase in maximum flow rate to 132l/min. The hydraulic system now also incorporates a load sensing system said to guarantee high hydraulic performance and smooth and efficient combined

Doosan has launched two new generation 6tonne compact excavators, the new DX62R-3 reduced tail swing (RTS) and DX63-3 conventional tail swing models.

Designed as replacements for the existing DX60R and DX55E machines, the new models are said to benefit from a significant improvement in hydraulic performance, through a 33% increase in maximum flow rate to 132l/min. The hydraulic system now also incorporates a load sensing system said to guarantee high hydraulic performance and smooth and efficient combined operations.  Two-way auxiliary hydraulic flow is also available for the primary auxiliary circuit for operating high flow attachments.

The DX62R-3 and DX63-3’s bucket digging force is now 4.4tonnes, 7% above the previous models. The arm digging force is 10% higher at 2.9tonnes. This is combined with a longer arm for a better overall working range. The traction force has also been increased by 5% to 5.6tonnes and travel speeds have been increased in both the low range (2.6km/h) and the high range (4.7km/h).

The space available in the new ROPS operator cab is similar to that found on much larger medium and heavy-duty machines. The cab has a large entrance and exit, ensuring it is easy to get in and out of the excavators. The interior of the cab has been ergonomically designed to optimise operator comfort and features an increased foot rest area and an additional cup holder. The openness of the cab is said to provide a wide field of view and excellent all-round visibility.  

The DX62R-3 and the DX63-3 models are powered by the Stage IIIA compliant 36.2 kW liquid-cooled 7139 Yanmar 4TNV94L diesel engine running at a maximum speed of 2,200rpm, said by 695 Doosan to provide abundant power and reliability for machines of this size.  Electronic injection together with automatic idle ensures optimum fuel efficiency at all times.  

The low noise and emission levels of both models ensure they are suitable for operation in noise sensitive areas and at night.  

The advanced technology used in the DX62R-3 and DX63-3 excavators complements the powerful performance with simple, easy maintenance procedures. Convenient check points make it easy to do routine maintenance, while a tilting cab simplifies service work. The large-capacity radiator enables performance in severe and continuous operations.

The large capacity two-stage forced air cleaner is claimed to remove over 99% of airborne particles, reducing the risk of engine contamination and lengthening the intervals for cleaning and cartridge change.

    Develon has launched the DX235RTF-7 tunnelling excavator, an extension to the company’s line-up of special application machines.

    The DX235RTF-7 is based on Develon’s well-established DX235LCR-7 reduced radius crawler excavator and is powered by a DL06V Stage V engine, providing 141kW of power. The DX235RTF-7 uses the successful compact design and minimum swing radius of the DX235LCR-7. However, the key part of the machine is the heavy duty tunnelling front, offering a new arm and boom design with special kinematics and a tilting function.
