Doosan Enters new registers in the market of the miniexcavators of 6 tonnes

Doosan has presented two new miniexcavators of 6 tonnes, the model DX62R-3 with twist of voladizo reduced (RTS) and the model DX63-3 with twist of voladizo conventional. Designed like replacement of the DX60R and DX55And, the new models incorporate advances in a lot of areas to reach the greater levels of performance, versatility, comfort, durability, ease of maintenance and service with the minimum impact for the health and the environingingment.

One of the characteristics stood out of the new excavators of 6 tonnes is the big increase of the hydraulics performance, that has reinforced with an impressesive increase of 33% in the maximum discharge until arriving to 132 l/min. Besides, the hydraulics circuit incorporates now a system of detection of load that guarantees a big hydraulics performance and allows soft combined operations and efficient. Also there is available a hydraulics discharge bisteeringal auxiliary in the primary auxiliary circuit for accionar the implementos of big discharge.

This complements with a significant increase of the strengths of excavation: the strength of excavation of the spoon is now of 4,4 tonnes, 7% more than in the previous models, and the strength of excavation of the balancín is 10% elder until arriving to 2,9 tonnes. This combines with a balancín longer to attain a better general perimeter of work. Also it has increased the strength of traction 5%, until reaching the 5,6 tonnes, as well as the speed of trip in first (2,6 km/h) and in second (4,7 km/h).

The space of the new cabin ROPS is seemed to the available in middle-sized machines and for tasks weighed a lot greater. The cabin has a big door to end to facilitate the entrance and the exit.

Besides, the cabin offers a level of lower noise of 73 dBA. It includes of series 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.

The interior designed ergonómicamente to optimise the comfort of the operator provides more space for the feet and a portavasos additional, whereas the open design 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 design of the two new excavators offers a big 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.

A new monitor LCD, to all colour of 5,7 inches, allows 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 control of the hydraulics discharge in shape of wheel allows to control the auxiliary hydraulics discharge (Aux1/Aux2), the twist and the inclination of the feather. Besides, in the new models are available the functions of automatic reduction of course and of nivelación of the leaf dózer.

Like characteristics of hygiene of series include valves of blockade in the cylinders of the balancín, of the feather and a device of warning of overloads. Other characteristics of series are the electrical bomb of repostaje and the desempañador of the windscreen.

The models DX62R-3 and DX63-3 have an engine diesel Phase IIIA Yanmar 4TNV94L of 36,2 kW refrigerated by liquid with a maximum performance of 2200 rpm, with which achieves a big power and reliability in machines 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 both models do that they are ideal to work of night or in sensitive zones to the noise.

The technology advanced used in the excavators DX62R-3 and DX63-3 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 radiator of big capacity allows the intense and continuous use of the excavator. Thanks to the easy access to the radiator and to the refrigerator, the cleaning results very easy. The distinct parts of the engine reach from a side, where the filter of oil of the engine and the filter of subject fuel to the body of the engine project to facilitate his maintenance.

The filter of air forced in two stages of big capacity deletes more than 99% of the particles of the air, reduces the risk of pollution of the engine and lengthens the intervals of cleaning and replacement of the cartridges. The tubes of grease integrated have designed to facilitate the maintenance of the rolling of twist and the cylinder of twist. The box of fuses is inside the compartment of storage that there is behind the seat of the operator. Also it provides sufficient space to adjust and substitute the belt of the fan with comfort.
