[. . . ] Output is 184 kW 246 HP, providing increased hydraulic power and improved fuel efficiency. Komatsu SAA6D114E-3 engine meets EPA Tier 3 and EU Stage 3A emissions certified and reduced NOx emission by 40%. The SAA6D114E-3 engine adopts the electronically controlled Heavy Duty HPCR* fuel injection system. *HPCR : High Pressure Common Rail Two-mode Setting for Boom Smooth mode provides easy operation for gathering blasted rock or scraping down operation. When maximum digging force is needed, switch to Power mode for more effective excavating. Smooth mode Power mode Idling Caution To prevent unnecessary fuel consumption, an idling caution is displayed on the monitor, if the engine idles for 5 minutes or more. Hydraulics Unique two-pump system ensures smooth compound movement of the work equipment. This system also reduces hydraulic loss during operation. Boom floats upward, reducing lifting of machine front. Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved. Low Operation Noise Enables a low noise operation using the low-noise engine and methods to cut noise at source. 4 5 PC300-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC300-8 0 WORKING ENVIRONMENT Safety Features Cab Dedicated to Hydraulic Excavator The cab is designed specifically for hydraulic excavators and gains reinforced strength from the pipe-structured cab framework. The cab framework provides the high durability and impact resistance with very high impact absorbency. The seat belt keeps the operator in the seat of the cab during a roll over. Lock Lever Locks the hydraulic pressure to prevent unintentional movement. Neutral start function allows machine to be started only in lock position. Large Side-view, Rear, and Sidewise Mirrors Enlarged left-side mirror and addition of rear and side mirror allow the PC300-8 to meet the new ISO visibility requirements. Low Cab Noise The newly-designed cab is highly rigid and has excellent sound absorption ability. Thorough improvement of noise source reduction and use of low noise engine, hydraulic equipment, and air conditioner allows this machine to generate a low level of noise. Wide Newly-designed Cab Newly-designed wide spacious cab includes seat with reclining backrest. The seat height and longitudinal inclination are easily adjusted using a pullup lever. You can set the appropriate operational posture of armrest together with the console. Reclining the seat further enables you to place it into the fully flat state with the headrest attached. Automatic Air Conditioner (optional) Enables you to easily and precisely set cab atmosphere with the instruments on the large LCD. The bi-level control function keeps the operator's head and feet cool and warm respectively. This improved air flow function keeps the inside of the cab comfortable throughout the year. Defroster function keeps front glass clear. Pump/engine Room Partition Pump/engine room partition prevents oil from spraying onto the engine if a hydraulic hose should burst. Thermal and Fan Guards Thermal and fan guards are placed around high-temperature parts of the engine and fan Low Vibration with Cab Damper Mounting PC300-8 uses viscous damper mounting for cab that incorporates longer stroke and the addition of a spring. The new cab damper mounting combined with high rigidity deck aids vibration reduction at operator seat. Anti-slip Plates Highly durable antislip plates maintain superior traction performance for the long term. drive. Rubber Spring Silicon Oil Pressurized Cab Optional air conditioner, air filter and a higher internal air pressure (+6. 0 mm Aq +0. 2"Aq) prevent external dust from entering the cab. 6 7 PC300-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC300-8 0 MAINTENANCE FEATURES Large LCD Color Monitor Large Multi-lingual LCD Monitor A large user-friendly color monitor enables safe, accurate and smooth work.
