Lower costs of exploitation with the new excavators of wheels of Doosan

These two machines, that come to substitute the ones of phase IIIA presented in 2006-2007, are the first excavators of wheels Doosan satisfied with the phase IIIB. Surpassing with grow the new requirements of broadcasts, the DX160W-3 and the DX140W-3 offer besides several new characteristics and other improved. They are designed to increase his profitability through a better ease of control and productivity, to the time that optimises the consumption of fuel. The total cost of exploitation reduces to a large extent maximizando the operative time thanks to the improvement of the quality, reliability, durability and ease of service.

So much the new excavator of wheels DX160W-3 like the DX140W-3 offer a substantial increase in the performance, regarding machines of the previous generation:

• Increase of the discharge of the main bomb of 8% and of the pressesure of the system until 350-370 kg/cm²
• Increase of the strengths of the spoons of 16% and of the strengths of the balancines of the 6-16 %.
• Increase of the capacity of elevation of the 3-12% in the leading part of the excavators.
• Increase of power of 2%, with 12% more than pair and 10% more than strength of traction.
• Until a 9 % of reduction of the consumption of fuel.
• Decrease of 5 dBA of the level of noise in the cabin.

In comparison with machines of the competition that there is in the market, the new excavators of wheels DX160W-3 and DX140W-3 offer an optimum balance between cilindrada and power; in addition to the greater strengths in the spoon and in the balancín beside a diagram of work optimised, which, in combination with the greater distance between axles, provides the greater capacity of available elevation in the market.

Both machines achieve new levels of confort, ease of handle, optimum and big balance mobility for multiple tasks like bearers of spoons, hydraulics hammers, forks carries-pallets, grapas and crushers for excavation, manipulation, transport and other applications. The new excavators of wheels result ideals for small or average works of civil engineering and projects of channelling and ways, in applications such like opening of resolve, break of surfaces of rock, concrete or asphalt, installation of boxes of entibación, nivelación, elevation of pipes, movement of pallets/material or load of trucks.

These new excavator can displace with ease of a work to another to almost 40 km/h. A low pressesure on the floor guarantees that the DX160W-3 and the DX140W-4 result adapted for his use on soft floors and out of the ways.

In general, the two models satisfy the needs of a wide variety of customers, included companies contractors, of civil engineering, rent, public services, maintenance of roads, recycling, gestión of waste or materials of construction.

In the controls includes of series a new function of selection and installation of implementos, with possibility to register 10 values pre-established. The joysticks have new switches basculantes proportional and integrated cheese cheese buttons that allow a precise control of the implementos. It has improved the disposal of the controls, with the most important switches grouped at hand in the right console.

A new console of control in colour of 7 inches and high visual quality offers an attractor trucks presentation and an excellent functionality. All the functions can control so much from the board of instruments, as by means of a new control of two speeds situated beside the joystick, that is an exclusive element of the excavator Doosan. The buttons of advance/deadlock/leaves backwards (FNR) of the joysticks allow to the operator change of steering without removing the hands of the crowbars.

The cabin with certification ROPS and OPG is 6% more espaciosa, whereas the new suspension of the cabin contributes to diminish the vibrations in 20%. In combination with a new system of refrigeration and ventilation, this has helped to reduce the level of noise in the cabin of 74 dBA to 69 dBA. The machines include of series a seat calefactado, totally regulable and with suspension that has designed to reduce the fatigue of the operator.

The cabin is presurizada to prevent the entrance of dust and dirt. The capacity of lighting has increased 100% to facilitate the nocturnal work. Like element of hygiene offers the option of a lateral camera. A greater zone glazed in the windows of the cabin allows an excellent peripheral visibility. Other characteristic are the column of steering finer to improve the visibility, a system of control of air conditioning totally automatic, a port USB to reproduce music or videos and more compartments for documents and other objects.

The excavators DX160W-3 and DX140W-3 are instrumented with the reliable engine diesel Doosan DL06KB turboalimentado of common pipe (‘common rail') and 6 cylinders, that offers 2% of increase of the power until 102 kW (137 CV) to 2.000 rpm and 12% more than pair engine. The engine DL06KB fulfils with the rule on broadcasts of phase IIIB thanks to the use of the technologies of recirculation of the gases of leakage (EGR) and of filter of particles diesel (DPF).

The new valves and hydraulics pumps increase the hydraulics discharge 8% and the pressesure of the system arrives until 350-370 kg/cm². The strength of traction has increased 10%. The greater hydraulics performance reinforces the functions of power, increases the capacities of elevation (until in 12% in the leading part), shortens the length of the cycles and improves the strengths of start. The pair of twist has increased 3%, whereas the strengths of the spoon and the balancín have done it 16%. In group, the hydraulics systems of the new generation improve the productivity of the machines by means of predictable controls and with greater capacity of answer.

The new indicator ECHO of the signpost of control allows to control in real time the consumption of fuel and the percentage of load of the engine to orient to the operator in the selection of the way of operation with lower consumption of fuel.

There is two new ways of operation (P+ for more power and L for elevation) that improve the control and the efficiency. The way of elevation has like end facilitate the handle of objects and heavy materials in applications of construction, which results of particular use to the hour to work in narrow spaces and reduced.

The proofs of factory show a reduction of until 9% in the consumption of fuel, depending of the way selected and of the work that do . The operator can choose between two new stages of ralentí: the first offers ralentí automatic to 800 rpm (before was of 1.000 rpm) after 3 seconds without that use the machine, and the another is a switch of deceleración with a touch in the joystick left. The capacities of ralentí and the embrague electronic that reduces the unnecessary operation of the fan contribute to that the new excavator are very efficient in the consumption of fuel.

The frame, the feather, the balancín and the inferior train of the new excavators of wheels DX160W-3 and DX140W-3 have reinforced to increase his durability. The result is that the useful life of the machine has lengthened to a large extent, what consolidates the reputation of reliability and durability of Doosan.

The excavators have a capó of easy opening of an alone piece. The filter DPF is very subject in a specific compartment. The filters, the valves and the batteries are situated in an easily accessible place. The capacity of refrigeration is between 10% and 15% higher that in the machines of the previous generation.

In addition to including more characteristic of series that other excavators of existent wheels in the market, the DX160W-3 and the DX140W-3 have a much wider assortment of options, like a system of floating feather to facilitate the nivelación and the finishing. The double bomb for applications highly demanding that provides additional discharge is available like option for implementos of high discharge. Other available options are leading equipment of work articulated or monobloque, leaves dózer, stabilisers, specific supports, hydraulics pipes auxiliaries, a box of tools bigger, a gun and compressesor of air to clean and a microphone/speaker for greater hygiene in the works.
