(8. 5 seconds of operation) Maximum arm crowd force (ISO): Hydraulic control valve Hydraulic system controller 218 kN (22. 2t) 259 kN (26. 4t) 233 kN (23. 8t) (with Power Max. ) 7% UP 7% UP Maximum bucket digging force (ISO): 278 kN (28. 3t) (with Power Max. ) Main pump are maintained. [. . . ] Ambient noise meets the EU Stage 2 noise regulation. Excellent Machine Stability Large counterweight offers superior machine stability and balance. Boom floats upward, reducing lifting of machine front. Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved. 4 5 PC450-8R H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC450-8R 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 safety of the cab during a rollover. Lock Lever Locks the hydraulic pressure to prevent unintentional movement. Neutral start function only allows machine to be started in lock position. Pump/Engine Room Partition Pump/engine room partition prevents oil from spraying onto the engine if a hydraulic hose should fail. 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. Thermal and Fan Guards Thermal and fan guards are placed around hightemperature parts of the engine and fan drive. Low Vibration with Cab Damper Mounting PC450-8R 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 anti-slip plates maintain superior traction performance for the long term. Large Serrated Steps Large Handrail Rubber Spring Pressurized Cab Silicon Oil Optional air conditioner, air filter and a higher internal air pressure (+9. 0 mm Aq +0. 35"Aq) prevent external dust from entering the cab. 6 7 PC450-8R H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC450-8R 0 MAINTENANCE FEATURES Large LCD Color Monitor Large Multi-lingual LCD Monitor A large user-friendly color monitor enables safe, accurate and smooth work. Improved screen visibility is achieved by the use of TFT liquid crystal display that can easily be read at various angles and lighting conditions. Displays data in 12 languages to globally support operators around the world. 8 4 5 6 7 Easy Maintenance Easy Access to Engine Oil Filter and Fuel Drain Valve 1 2 3 Large-size Steps On both right and left track frames are fixed with wider steps for easier maintenance. Long-life Oil, Filter Uses high-performance filtering materials and long-life oil. Extends the oil and filter replacement interval. Hydraulic oil filter (Eco-white element) Engine oil & Engine oil filter Hydraulic oil Engine oil dipstick and fill, and fuel filter are mounted on same side to improve accessibility. Fuel drain valve are remotely mounted to improve accessibility. Large Capacity Air Cleaner Large capacity air cleaner is comparable to that of larger machines. The larger air cleaner can extend air cleaner life during long-term operation Hydraulic oil filter 500 hours every 5000 hours every 1000 hours every Long Work Equipment Greasing Interval High quality BMRC bushings and resin shims are optionally available for work equipment pins excluding bucket, extending greasing interval to 500 hours. 1 2 3 Indicators 1 2 Auto-decelerator Working mode Basic operation switches 5 Hydraulic oil temperature gauge 6 Fuel gauge 7 Eco-gauge 8 Function switches menu Function switches 4 5 6 and prevents early clogging and resulting power decrease.
