Doosan Optimises the consumption of fuel in his new excavadora of wheels

Designed and built to obtain a high productivity in tasks of excavation, elevation, transport and other applications for wheel excavators, the DX140W-3 has like end surpass the requirements of the customer regarding performance, ease of handle, saving of fuel, reliability, durability and general reduction of the costs of operation. The DX140W-3 has been designed to satisfy the needs of a wide variety of customers, included companies contractors, of civil engineering, for hire, of public services, of maintenance of roads, of recycling, of waste management and of materials of construction.

The new cabin recognised with ROPS and OPG offers more space for the operator, whereas the new system of suspension of the cabin helps to reduce the vibration in 20% and to mitigate the noise inside the cabin until levels of 70 dB(To). The machine includes of series a seat calefactado, with pneumatics suspension, designed to reduce the fatigue of the operator. The joysticks have new switches giratorios proportional and integrated cheese cheese buttons that offer a precise and proportional control of the implementos. The buttons of neutral / advance / shrinking (FNR) of the joysticks allow to the operator change of steering without removing the hands of said controls.

A new console of control in colour of 7 inches and high 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 beside the joystick, that is an exclusive element of the excavadoras Doosan. Like characteristic of series, the operator has access to a new function of selection and configuration of implementos, with multiple values preseleccionados grabables.

The cabin is presurizada to prevent that they go in particles. The capacity of lighting has increased 100% to facilitate the work at night. Like element of hygiene, offers the option of a lateral camera. A greater zone glazed in the windows of the cabin offers an excellent peripheral visibility to the operator. Other characteristic are the column of steering finer, a system of control of the climatizador totally automatic, a port USB to reproduce music and videos and more compartments of storage for documents or other objects.

The DX140W-3 is instrumented with the reliable engine diesel turbocomprimido Doosan DL06K of six cylinders with injection “common rail” that develops 101 kW (135 CV) of power to 2000 r.P.m. The engine DL06K fulfils with the rule on broadcasts of Phase IIIB thanks to the use of the technologies post-treatment EGR (recirculation of the gases of leakage) and DPF (filter of particles diesel).

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 facilitate to the user the selection of the way of operation in which it consumes less fuel. The two new ways (P+: Power Plus and L: Lifting) improve the ease of handle and the efficiency. The new way of elevation has like end facilitate the handle of objects and heavy materials in applications of construction; this function results of particular use to the hour to work in narrow spaces and closed in projects of public services and construction of roads.

The proofs of factory show a reduction of between 5% and 10% in the consumption of fuel, depending of the way selected and of the work that do . The ralentí automatic and an embrague electronic to reduce the unnecessary operation of the fan contribute also to the saving of fuel.

In comparison with the previous model, the load of work by hour has increased like average 5% in the different ways of power, whereas the capacities of elevation have increased around 15%. The new pumps and hydraulics valves increase the hydraulics discharge around 4%. The increase of the hydraulics pressesure power the leading functions and of power, increases the capacities of elevation, reduces the cycles and increases the strength of start. The pair of twist has increased around 4%, what supposes an increase of the strength of excavation of the balancín and the spoon of 7%.

In group, the hydraulics systems of new generation improve the productivity of the machine by means of predictable controls and with greater capacity of answer.

The frame, the feather and the balancín of the new excavadora DX140W-3 have reinforced to increase his durability. Like result, the useful life of the machine has expanded of significant way, what consolidates the reputation of reliability and durability of Doosan.

The capó of the engine is divided in four parts to facilitate the works of maintenance and his opening. The easy access to the filters, the valves and the batteries also contributes to facilitate the works of maintenance. The capacity of refrigeration has increased between a 10 and 15% in comparison with the machine of the previous generation.

In addition to offering more characteristic of series that other excavadoras of his existent type in the market, has a very wide 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 for implementos of high discharge is available like option. Other available options for the DX140W-3 are a frontal equipment of work monobloque or articulated, leaves dózer, stabilisers, support of setting and all the hydraulics pipes auxiliaries that are necessary.
