Compact Excavator

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.

Colour LCD monitor panel

The new 5.7” colour LCD panel is located within the operator’s line of sight. The monitor is user-friendly and gives access to machine settings, maintenance data and auxiliary flow control. Any abnormality is clearly displayed on the screen, allowing you to work safely and confidently with an accurate overview of all conditions.

Gauges

• Engine coolant and hydraulic oil temperatures

• Engine speed

• Fuel level

• Eco symbol: changes colour when operating conditions change (idle, normal or loading)

• Eco gauge: shows the average fuel efficiency over the last minute of operation

• Warning symbols (12)

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.

Tilting cab

To simplify access to maintenance components.

Centralised greasing points

To make maintenance easier, the greasing points have been centralised.

Battery cut-off switch

For more safety and to maintain battery capacity.
