New reduced radius Stage IIIB compliant Doosan DX85R-3

By Lindsay Gale09 October 2013

Doosan has introduced its new generation 8.6 tonne DX85R-3 reduced tail swing (RTS) excavator that replaces its DX80R model. Power comes from a Yanmar 4TNV98C diesel engine providing 44.3 kW (60 hp) at 2100 rpm that meets Stage IIIB emission requirements through the use of exhaust gas recirculation (EGR) and diesel particulate filter (DPF) after-treatment technologies.

According to the company, the machine has been designed to exceed ‘voice of customer’ requirements by establishing a new benchmark for productivity, fuel efficiency, enhanced controllability and operator comfort, together with improved reliability, durability and reduced maintenance costs.

Complementing the 10% increase in power over the DX80R model, the new DX85R-3 excavator offers excellent fuel efficiency, among the best in its class. The bucket digging force of 6.3 tonne also represents an increase of 12% over the previous model.

The DX85R-3 excavator has a new load sensing system that provides a guaranteed improvement in hydraulic performance and allows smooth and efficient combined operations. The traction force has also been increased by 7% to 6.6 tonnes, with travel speeds remaining the same in both the low range (2.7 km/h) and the high range (4.7 km/h).

The new ROPS cab offers a much lower noise level of only 71 dBA. Doosan claims that the space in the cab is similar to that found on much larger medium and heavy-duty machines and the openness of the cab provides a wide field of view and excellent all around visibility. The cab also has a large entrance and exit, giving good access for getting in and out of the machine.
