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 PC270-8 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 similar to that of a passenger car. 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. Highly durable antislip plates maintain superior traction performance for the long term. Rear View Monitoring System (optional) The operator can view the rear of the machine with a color monitor screen. Low Vibration with Cab Damper Mounting PC270-8 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 Monitor for rear view camera Thermal and Fan Guards Thermal and fan guards are placed around hightemperature parts of the engine and fan 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. Pump/engine Room Partition Pump/engine room partition prevents oil from spraying onto the engine if a hydraulic hose should burst. 6 7 PC270-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC270-8 0 MAINTENANCE FEATURES Large LCD Color Monitor Large Multi-lingual LCD Monitor A large user-friendly color monitor enables safe, accurate and smooth work.
