All-round versatility and improved fuel efficiency
Whatever your application you can rely on the DX85R-3 ideal working range with reduced tail swing to take
on all these tasks with efficient, dependable performance that saves you time and money.
• Optimised engine, now compliant with the Stage IIIB European regulations using EGR (Exhaust Gas
Recirculation) and DPF (Diesel Particulate Filter)
• Improved load sensing closed-centre hydraulic system uses the engine power more effectively, maximising
pump output and offering more comfort, smoothness and accuracy regardless the load
• Increased digging power, swing torque, lifting capacity, travel speed and traction force for higher performance
• Improved fuel efficiency means you can keep costs down and reduce the environmental impact
• The dozer blade float function allows fast finishing work, simply by travelling backwards
| Higher gradeability and work capability Thanks to the high tractive effort and strong swing torque, the DX85R-3 offer excellent capability for working on slopes. |
Boom swing The swing bracket and the boom swing cylinder size ensure powerful and stable performance. |
RPM dial / Auto idle Thanks to the electronic control, the optimal engine rpm can be set per workload. The auto idle function applied as standard helps fuel efficiency and reduces noise levels. |
Main control valve The machine can be precisely controlled in single and complex operations and the front hydraulic flow matched to the work load. This contributes to great fuel economy and smooth operation. |
Maximum controllability in every situation
Proportional auxiliary flow means that the excavator’s power is matched by smooth, confident manoeuvres.
Using sensitive joysticks and clear controls positioned for convenient access, you are able to work safely
and confidently with minimum effort. Even the switches have been ergonomically placed on the right-hand
control stand and positioned according to the frequency with which they are used. The highest standards of
efficiency are just a finger’s reach away.
The ideal workspace – designed around you
The DX85R-3 is designed to provide you with the best possible working conditions. The sophisticated ROPS
cab is ISO-certified for your safety. Its spacious interior offers a fully adjustable and comfortable seat.
Comfortably seated, you have easy access to several storage compartments and a clear all-round view of
the worksite. Noise and vibration levels are reduced while air conditioning allows you to maximise your
productivity and return on investment.
| Ergonomic operator environment Spacious cab with ample leg room, robust ergonomic pedals, large & flat floor, cup holder, etc. |
Adjustable seat, head rest and arm rests For more operator comfort. |
Air conditioning Allows the operator to adjust the airflow to suit conditions. |
More durability – less maintenance
A reinforced X-chassis provides strength, while the optimised boom shape ensures uniform load distribution
for more durability. Top quality materials, the most advanced computer-aided design and endurance testing
under the most demanding conditions ensure your excavator will keep on performing.
The DX85R-3 is designed for low maintenance with longer intervals resulting in more machine availability
while skilled Doosan-trained technicians are available to provide extra support when needed.
