Doosan Launches New Stage IIIB Compliant 8 tonne Excavator

Waterloo, Belgium - Doosan has launched the new generation DX85R-3 reduced tail swing (RTS) excavator to replace the company’s previous DX80R model. The new DX85R-3 excavator is powered by a Yanmar 4TNV98C diesel engine providing 44.3 kW of power at a rated speed of 2100 rpm, meeting Stage IIIB emission requirements through the use of exhaust gas recirculation (EGR) and diesel particulate filter (DPF) after-treatment technologies.

This new generation, reduced tail swing excavator goes far beyond just meeting the new emission regulations and has been designed to exceed ‘voice of customer’ requirements by establishing a new benchmark for productivity, fuel efficiency, enhanced controllability and high 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 which 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 tonne, whilst travel speeds remain the same in both the low range (2.7 km/h) and the high range (4.7 km/h).

High Comfort Cab – Low Noise and Safety Throughout

The new ROPS cab offers a much lower noise level of only 71 dBA.  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.

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 cab lighting, sun visor and side mirror all contribute to a safe and pleasant working environment for the operator. 

The position and angle of the seat cushion as well as the position of the consoles can be adjusted to suit the operator.  Additional comfort is provided by the seat back pocket and the lumbar support.  A seat heater is available as an option.

The DX85R-3 excavator is designed for easy, precise controllability with the left and right control stands ergonomically placed for convenient operation.  The proportional hydraulic joystick levers have comfortable grips that allow the operator to perform smooth, precise actions. 

The cab is equipped with a new full colour 5.7 inch LCD monitor that allows operators to control auxiliary flow and other functions such as monitoring service periods.  The control panel provides comprehensive information about the status of the machine and there is anti-theft protection as standard through a password lock-out system. 
Hydraulic flow control is enabled via roller software for control of auxiliary hydraulic flow (Aux1/Aux2), boom swing (offset) and tilting operations.  In addition, auto down shift and dozer float levelling functions are all now available on this new model.

A high capacity heating and air conditioning system is standard, with fully adjustable vents installed at both the front and rear of the operator's seat to maximise efficiency.  Other standard features include an electric refuelling pump and a defroster for the windshield. 

Safety lock valves on the arm and boom cylinders and an overload warning device are all standard features and an optional rear camera provides an additional safety feature on the DX85R-3 excavator.

Easy Maintenance

The advanced technology and powerful performance of the new DX85R-3 excavator are complemented by the simple, easy maintenance procedures required for the machine.  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.  Access to the radiator and cooler is easy, making cleaning a simple process.  The various parts of the engine can be accessed from the side, with the engine oil and fuel filter attached to the engine body extending out for easy maintenance.

The large capacity two-stage forced air cleaner removes over 99% of airborne particles, reducing the risk of engine contamination and lengthening the intervals for cleaning and cartridge change.  Integrated grease piping is designed for easy maintenance of the swing bearing and swing cylinder.  The fuse box is conveniently located in a section of the storage compartment behind the operator's seat.  Sufficient space is also provided for easy adjustment or replacement of the fan belt.
