Doosan Launch New Mini-Excavators: Doosan is launching new versions of the company’s very successful DX62R-3 and DX63-3 6 tonne and DX85R-3 8 tonne mini-excavators that meet Stage V engine emission regulations.

The new Stage V DX85R-3 8 tonne reduced tail swing (RTS) excavator from Doosan is powered by the Yanmar 4TNV98C Common Rail direct injection diesel engine, providing 44.3 kW of power at a rated speed of 2100 rpm. It meets Stage V emission requirements through the use of exhaust gas recirculation (EGR) and diesel particulate filter (DPF) after-treatment technologies.

The new Stage V versions of the 6 tonne DX62R-3 RTS and DX63-3 conventional tail swing models are powered by the same Yanmar 4TNV98C diesel engine, providing a massive 22% increase in engine power over the previous generation models.

The DX62R-3, DX63-3 and DX85R-3 mini-excavators are designed to offer maximum performance, versatility, operator comfort, durability, ease of maintenance and serviceability in their respective classes.

As well as the huge increase in engine power, another of the stand-out features on the 6 tonne excavators is the hydraulic performance, with a maximum flow rate of 132 l/min. The hydraulic system incorporates a load sensing system which guarantees high hydraulic performance and allows smooth and efficient combined operations.

This is complemented by the high digging forces on both machines – the bucket digging force is 4.4 tonne and the arm digging force is 2.9 tonne. This is combined with a longer arm for a better overall working range. The traction force is 5.6 tonne and travel speeds are 2.6 km/h in the low range and 4.7 km/h in the high range.

The DX85R-3 excavator offers excellent fuel efficiency, among the best in its class. The bucket digging force is an impressive 6.3 tonne and this is combined with a traction force of 6.6 tonne, whilst travel speeds are 2.7 km/h in the low range and 4.7 km/h in the high range.

High Comfort Cab – Low Noise & Optimum Safety

The space available in the ROPS operator cabs on the DX62R-3, DX63-3 and DX85R-3 mini-excavators is similar to that found on much larger medium and heavy-duty machines. The cabs have a large entrance and exit, ensuring it is easy to get in and out of the machines.

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. The interior of the cabs has been ergonomically designed to optimise operator comfort and features an ample foot rest area and an additional cup holder, and the openness of the cabs provides a wide field of view and excellent all-round visibility. 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.

All the excavators are 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.

There is a full colour 5.7 inch LCD monitor that allows operators to control auxiliary flow and to monitor functions such as service periods. The control panel provides comprehensive information about the status of the machine and there is anti-theft protection as standard via 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 the new models.

Safety features as standard include lock valves on the arm and the boom cylinders and an overload warning device. Other standard features include an electric refuelling pump and a defroster for the windshield.

The low noise and emission levels of all three models ensure they are suitable for operation in noise sensitive areas and at night.

Easy Maintenance

The advanced technology used in the excavators complements the powerful performance with simple, easy maintenance procedures. 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.
