The new Doosan DX140LCR-3 offers more power and productivity in small spaces

The new model satisfies the increasing demand of machines with little radio, like alternative to the conventional models, for his use in urban works, channelling, roads, railway industrys, bridges and other works of construction in spaces reduced. Designed to surpass the expectations of the customers regarding productivity, confort, reliability, durability and low operative costs, the new excavator DX140LCR-3 will interest to engineers of ways, contractors, companies of supplies, companies for hire, paisajistas and many others possible customers that look for to increase the profits and rentabilizar to the maximum his investment.

The excavator DX140LC-3 is instrumented with the engine diesel Cummins QSB 4.5 turboalimentado common rail and four cylinders that fulfils the norms of broadcasts of motors 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 engine works to 2.200 rpm, surrenders 10% more than power [81 kW (108 CV) (SAE J1995)] and produces 15% more than pair engine (49,8 kgf.m) Regarding the previous model DX140LCR, satisfied with the phase IIIA, what represents an increase of the relation between productivity (m³/h) and consumption of fuel (l/h) of 10%, depending of the way of operation selected and of the work that do .

The strengths of the balancín and of the ladle have increased until in 8%, whereas the speed of trip can arrive now to 3,2 and 5,3 km/h in first and in second, respectively. To consequence of the incorporation of a counterweight 400 heavier kg (3500 kg), the capacity of elevation of the DX140LCR-3 also has increased 15%.

The new cabin with certification ROPS and OPG offers more space for the operator and several useful characteristics, like the direct control by means of the joysticks, that have new switches giratorios proportional and integrated buttons to allow a handle precise of the implementos.

A new console of optical control in colour of 7 inches and high quality offers an attractor trucks presentation and an excellent functionality. All the functions can control from the signpost of instruments, that includes of series a new control for implementos that allows that the operator register and select parameters of pressesure and hydraulics discharge to handle until 10 implementos different. The signpost of control presents a new ergonomic design, with the switches of frequent use situated at hand in the right console.

Between the characteristics of series are the system regulable of air conditioned and a new seat with pneumatics suspension calefactado of big quality, that can glide advance and backwards together with the supports of the controls of the two sides. The confort of the seat is optimum for the operator thanks to the regulation of the height and to the adjust lumbar.

The new excavator of orugas DX140LC-3 has an inferior train more robust with components reinforced (such as the toothed wheels or the links and docks of the orugas). The feather and the balancín also have reinforced by means of the increase of the thickness of the metal in critical points and the use of casquillos reinforced.

Has loaned special attention to improve the access to the components during the maintenance, by what can arrive to the engine, the bomb, the filters, the radiador, the valves and the batteries easily through several compartments delivered by the machine.

A fan of electrical operation active of automatic form so that the engine and the hydraulics systems keep to an optimum temperature. This improves the efficiency of the refrigeration and diminishes the consumption of fuel.

The excavator DX140LCR-3 offers with leading team of work monobloque (of series) or articulated (optional); other options are the leaf dózer or the swearwords of rubber of 500 mm for the orugas. The swearwords have by object reduce the deterioration of the asphalt in urban works.
