4 Performance The performance of the DX140LCR has a direct effect on its productivity. Its new Coon Rail engine and new e-epos controlled hydraulic system have combined to create an unbeatable hydraulic excavator, with a cost/performance ratio that makes the DX140LCR even more appealing. At the heart of the hydraulic excavator is the new Coon Rail Cuins QSB 4.5 engine. It is combined with the new e-epos electronic control system, for optimum power and fuel saving. The new engine produces 95 Hp (71 kw/96 Ps) at only rpm, and more torque, due to its careful design combined with the use of coon rail injection and 4 valves per cylinder. These features help optimize combustion and minimize pollution through reduced Nox & particulate emissions. Increased torque allows efficient use of the power of the hydrau lic system. Faster working cycles increase productivity. Increased torque means the excavator is able to move more easily. Energy efficiency reduces fuel consumption. Cuins QSB 4.5 Coon rail engine 33% Reduced Tail Swing Radius It can be easily used in the city and tight locations, due to reducing the tail swing radius up to 33%. Rear protusion from track is only 15,5 to 23,5 cm 4

5 Excavator control New e-epos system (Electronic Power Optimizing System) The brains of the hydraulic excavator, the e-epos, have been improved and now can electronically link to the engines ECU (Electronic Control Unit), through a CAN (Controller Area Network) counication link, enabling a continuous exchange of information between the engine and the hydraulic system. These units are now perfectly synchronised. The advantages of the new e-epos impacts at several levels. Ease of operation and user-friendliness: The availability of a power mode and a normal operating mode guarantee maximum efficiency under all conditions. Electronic control of fuel consumption optimizes efficiency. The automatic deceleration mode enables fuel saving. Regulation and precise control of the flow rate required by the equipment are available as standard. A self-diagnosis function enables technical problems to be resolved quickly and efficiently. An operational memory provides a graphic display of the status of the machine. Maintenance and oil change intervals can be displayed. Bucket Cylinder Arm Cylinder Boom Cylinder & Swing Motor Boom Load holding valve DOOSAN Infracore is aware of the importance of protecting the envi ronment. Ecology was uppermost in the minds of the research workers right from the start of the design of the new machines. The new challenge for the engineers is to combine the protection of nature with equipment performance and to this end DOOSAN has been investing heavily Dozer Blade (optional) The pin type design allows the dozer blade to be mounted on the front and is used for leveling, clean-up work and for stabilizing the machine during digging applications. The large dozer bottom and parallel design provide minimized ground pressure. 0 CO HC + Nox Particles n QSB 4.5 engine n Level IIIa limit The new engine respects and protects the environment, limiting all types of toxic emissions. Hydraulic Pump The main pump has a capacity of 2 x 114 l/min (at rpm) reducing cycle time while a high capacity gear pump improves pilot line efficiency. Swing drive Shocks during rotation are minimized, while increased torque is available to ensure rapid cycles. 5

6 Control The hydraulic excavator s power, durability, ease of servicing and its precise control increase its effectiveness and life expectancy. With the DX140LCR, DOOSAN offers an excellent return on investment. Multi-function colour LCD monitor panel Choice of operating modes Work mode Digging mode: for general excavation, loading, lifting Trenching mode: swing priority for trench work, canal digging, embankments Power mode Standard: uses 85% engine power for all work (optimum fuel efficiency) Power: uses 100% engine power for heavy work Operating modes Mode selection Flow rate control Auto deceleration Display selection Control lever Very precise control of the equipment increases versatility, safety and facilitates tricky operations requiring great precision. Levelling operations and the movement of lifted loads in parti cular are made easier and safer. The control levers have additional electrical buttons for control ling other additional equipment (for example, grabs, crushers, grippers, etc.). Control panel With colour LCD display Standard screen Anti-theft function Filter/oil information Operation history Flow rate control Contrast control 6

7 Comfort The work rate of the hydraulic excavator is directly linked to the performance of its operator. DOOSAN designed the DX140LCR by putting the operator at the centre of the development goals. The result is significant ergonomic value that improves the efficiency and safety of the operator. More space, better visibility, air conditioning, a very com fortable seat These are all elements that ensure that the operator can work for hours and hours in excellent condi tions. Rear camera Control panel Correct positioning with clear controls makes the operator s task easier. The high performance air conditioning provides an air flow which is adjusted and electro ni cally controlled for the conditions. Five operating modes enable even the most demanding operator to be satisfied. Visibility has been improved in all directions and the size of the cab has been increased Appropriate storage spaces show the atten tion given to the operator. Independently adjustable control module height Comfortable fully adjustable seat Air suspension seat (option) An air suspension seat is available as an option, which further reduces any vibration being transmitted to the operator while working or travelling. In addition, this option is fitted with a heating system for operator comfort in cold weather. Dozer control (option) The Dozer Control Lever is positional above the left-hand conrtol stand to secure easy and convenient access. 7

8 Reliability The reliability of an item of plant contributes to its overall lifetime operating costs. DOOSAN uses computer-assisted design techniques, highly durable materials and structures then test these under extreme conditions. Durability of materials and longevity of struc tu res are our first priorities. X-chassis The X-chassis frame section has been designed using finite element and 3-dimensional computer simulation, to ensure greater durability and optimum structural integrity. The swing gear is solid and stable. Strengthened boom The shape of the boom has been optimized by finite elements design, allowing the loads to be better distributed throughout the structure. This combined with increased material thickness means improved durability and reliability by limiting element fatigue. Arm assembly In the arm assembly greater strength has been gained by using cast elements and reinforcement around the bosses to give it an increased lifetime. D-type frame The D-type frame and chassis frame add strength and minimize distortion due to shocks. Bucket Highly wear-resistant materials are used for the most susceptible elements such as the blades, teeth, rear and lateral reinfor ce ment plates and corners of the bucket. Bushing A highly lubricated metal is used for the boom pivot in order to increase the life time and extend the greasing intervals to 250 hours. A rolled bushing with very fine grooves has been added to the arm to bucket pivot, so that greasing is only requi red every 50 hours. Ultra hard wear-resistant discs New materials have been used in order to increase the wear resistance and to increa se the service intervals. The longevity is greatly increased by the addition of wear plates on the inside and the outside of the bucket lugs. 8

9 Tracks The chain is composed of self-lubricating sealed links isolated from all external contamination. The tracks are locked by mechanically bolted pins. Polymer shim A polymer shim is added to the bucket pivot to maintain precise control over the equipment. Integrated Track Spring and Idler The track spring and the idler have been joined directly to achieve high durability and improved maintenance convenience. 9

10 Maintenance Short maintenance operations at long intervals increase the availability of the equipment on site. DOOSAN has developed the DX140LCR with a view to high profitability for the user. Engine oil filter The engine oil filter offers a high level of filtration allowing the oil change interval to be increased to 500 hours. It is easy to access and is positioned to avoid contaminating the surrounding environment. Easy maintenance Access to the various radiators is very easy, making cleaning easier. Access to the various parts of the engine is from the top and via side panels. Hydraulic oil return filter The protection of the hydraulic system is made more effective by the use of glass fibre filter technology in the main oil return filter. This means that with more than 99,5% of foreign particles filtered out, the oil change interval is increased. Air cleaner The large capacity forced air cleaner removes over 99% of airborne particles, reducing the risk of engine contamination and making the cleaning and cartridge change intervals greater. Fuel filter High efficiency fuel filtration is attained by the use of multiple filters, including a fuel filter fitted with a water separator that removes most moisture from the fuel. PC monitoring A PC monitoring function enables connection to the e-epos system, allowing various parameters to be checked during maintenance, such as pump pressures, engine rotation speed, etc, and these can be stored and printed for subsequent analysis. Centralized grease inlets for easy mainte nance The arm grease inlets are grouped for easy access. 10
