[. . . ] The cab's noise levels have been additionally reduced by improving the door seals for the cab and engine compartments. The use of an insulated engine compartment with sound-damping material also reduces noise. 1 2 3 1 Wide, Comfortable Operating Space 2 Steel Cover Sunroof 3 Dial Type Engine Speed Switch and / Key Switch Radio CD Control R250LC-7A_new_en 28-08-2007 12:03 Pagina 5 HYUNDAI CONSTRUCTION EQUIPMENT 04 / 05 R250LC-7A_new_en 28-08-2007 12:03 Pagina 6 Robex 250LC-7A Improved Intelligent Display Instrument Panel is installed in front of RH console box. It is easy to check all critical systems with easy-to-read indicators. Minimization of Shock and Vibration through Cab Mounting System The application of the Viscous Mounting system to the cabin support provides the operator with a smoother ride. The operator work efficiency will increase as the shock and noise level in the cabin decreases. Operating Environment Storage box and Cup Holder An additional storage box and cup holder are located behind operator's seat. [. . . ] This decreases fuel consumption and reduces cab noise levels. Boom & Arm Holding System The holding valves in the main control valve prevent boom & arm lowering during an extended period in a neutral position. 2 1 3 Arm Flow Regeneration System Arm flow regeneration valve provides smooth arm-in operation without cylinder cavitation. 1 POWER MODE H mode: High power S mode: Standard power WORK MODE Heavy duty work General work Breaker Max. Flow Cut-off System reduces pump flow, thus allowing smooth operation. Hydraulic Damper in Travel Pedal Improved travel controllability & feeling during travel of the machine by use of shock reducing materials. 2 3 USER MODE M mode: Maximum Power U mode : Memorizing Operator's Preferable Power Setting R250LC-7A_new_en 28-08-2007 12:03 Pagina 9 CUMMINS QSB6. 7 Engine The six cylinder 4 cycle Turbo Charged Engine with Charged Air Cooling, Has High Power output, Reliability, economical, and low emission. This engine meets Tier III emissions regulations. The Definition of Progress The Quantum System B Series 6. 7-liter engine combines full-authority electronic controls with the reliable performance. The electronics with the QSB6. 7 have been proven with our high-horsepower productsworking in the harshest, most demanding environments-search as dusty, nonstop mining operations while meeting emissions regulations worldwide. The QSB6. 7 features 24 valve designed with centered injectors and symmetrical piston bowl. The combination of improved airflow and evenly dispersed fuel results in increased power, improved transient reponse and reduced fuel consumption. Increased Higher Performance Reinforced Bucket and Bucket Linkage To prevent excessive wear of pins and bushes, sealed joints have been applied. Bucket link design incorporates high durability and anti wear characteristics. Thicker steel and an additional lateral plate are put in place to reinforce the bucket. Strong and Stable Lower Frame The reinforced box-section frame is all welded, with low-stress, high-strength steel. It guarantees safety and resistance against external impact when driving on rough ground and working on wet sites. The use of highly durable upper and lower rollers and track guards ensures proper machine transfer on all terrains. The long undercarriage incorporates heavy duty excavator style components. An X-leg type center frame is integrally welded for maximum strength and durability. Powerful and Precise Swing Control Improved shock absorbing characteristics make stopping swing movement a precise and smooth action. Track Rail Guide & Adjusters Durable track rail guides keep track links in place. Track adjustment is made easy by using a standard grease operated cylinder track adjusters including shock absorbing springs.
