Doosan Presents the prototype of the new excavator of 6 tonnes
7 June 2013
One of the characteristics stood out of the new excavator DX62R-3 is the extraordinary increase of the hydraulics performance, that has improved with 33% of increase of the maximum discharge, until 132 l/min. Besides, has entered a new system of detection of the load that improves even more the hydraulics performance and allows soft combined operations and effective. Now also it is available the hydraulics discharge bisteeringal auxiliary in the primary auxiliary circuit for accionar the implementos of high discharge.
The strength of excavation of the excavator DX62R-3 of new generation has increased significantly: the one of the spoon is now of 4,4 tonnes (7% more than the current machine) and the one of the balancín has increased in a similar percentage until 2,9 tonnes. This combines with a balancín longer to attain a better general perimeter of work.
Also has increased the strength of traction 5%, until 5,56 tonnes, as well as the speed of trip in first (2,6 km/h) and in second (4,7 km/h).
In the interior, is instrumented with a new monitor LCD, to all colour, of 5,7 inches so that the operators can control the auxiliary discharge and other functions, like the supervision of the periods of maintenance. The signpost of controls provides complete information on the state of the machine and incorporates protection antirrobo of series by means of blockade by password.
The design of the excavator DX62R-3 procures ease and precision of control with the supports of the right and left controls situated ergonómicamente to work with comfort. The crowbars (joysticks) hydraulics proportional have comfortable mangos so that the operator act with softness and precision.
The control of the hydraulics discharge has form of wheel and controls the auxiliary hydraulics discharge (Aux1/Aux2) and the twist and the inclination of the feather. Besides, in the model DX62R-3 are available the functions of automatic reduction of course and of nivelación of the leaf dózer.
The interior of the cabin, designed ergonómicamente to optimise the confort of the operator, provides more space for the feet and a portavasos additional, whereas the amplitude of the cabin offers a field of wide vision and an excellent peripheral visibility. The lighting of the cabin, the parasol and the lateral rear-view mirror contribute to that the surroundings of work of the operator was safe and pleasant.
The operator can regulate to his taste the position and the angle of the seat, as well as the location of the consoles. For greater comfort, the seat includes lumbar support and back pocket and can endow of optional heating.
The cabin offers a level of lower noise, of alone 73 dBA. Of series includes a system of heating and air conditioned of big capacity, with exits of air regulables so much in front as behind the seat of the operator for maximizar the efficiency. Other characteristics of series are the electrical bomb of repostaje and the desempañador of the windscreen.
The excavator DX62R-3 possesses an engine diesel of 36,2 kW refrigerated by liquid and satisfied with the phase IIIA, that works to a maximum diet controlled of 2.350 rpm, with a lot of power and reliability for a machine of this size. The electronic injection and the ralentí automatic guarantee an optimum consumption of fuel at all times. The low levels of noise and broadcasts of the model DX62R-3 do it ideal to work at night or in sensitive zones to the noise.
Thanks to the design with twist reduced of the voladizo (RTS) and to the function of twist of the feather, the excavator DX62R-3 can work well in narrow spaces and reduced. Also it exists the option of balancín long.
The technology advanced used in the DX62R-3 complements the powerful performance with operations of simple and easy maintenance. The periodic reviews and the maintenance facilitate thanks to the comfortable checkpoints and to the possibility to bend the cabin.
The radiador of big capacity allows the intense and continuous use of the excavator. Thanks to the simple access to the radiador and to the refrigerador, results very easy to clean them. The distinct parts of the engine reach from a side, where the oil of the engine and the filter of subject fuel to the body of the engine project to facilitate his maintenance.
