Doosan has launched the new DX85R-7 8 tonne mini-excavator, the latest addition to the company’s next generation range of Stage V mini-excavators.
The DX85R-7 reduced tail swing (RTS) excavator is designed to offer maximum performance, optimum stability, increased versatility, enhanced operator comfort, controllability, durability, ease of maintenance and serviceability.
The DX85R-7 utilises a newly improved upper structure platform offering increased durability and robustness and a different boom swing cylinder layout resulting in an increased boom swing angle of 60o.
Together the RTS design and boom swing angle make the DX85R-7 ideal for work in confined spaces on projects in construction, landscaping, utilities, rental, agriculture, recycling, waste and many other areas. The bucket digging force of the DX85R-7 is 6.7 tonne and this is combined with a traction force of 6.6 tonne, whilst travel speeds are a mobile 2.9 km/h in the low range and 4.8 km/h in the high range.
As well as sharing the new global styling common to all the new Doosan mini-excavators from 2 to 10 tonne, the DX85R-7 is powered by the Doosan D24 Stage V compliant diesel engine providing 48.5 kW (65 HP) of power at 2100 RPM.
As a result, the DX85R-7 excavator offers excellent fuel efficiency, among the best in its class. It also combines exceptional power output and high torque at low RPM, more than 9% more than the previous DX85R-3 model.
A combination of Diesel Oxidation Catalyst and Diesel Particulate Filter aftertreatment methods ensure compliance with Stage V regulations. The DPF offers a 25% increased ash cleaning period of 5000 hours compared to the DX85R-3.
