[. . . ] The larger digging forces generate the largest production in the 30 ton 33 U. S. *Arm Crowd Force: 171 kN 17400 kgf 38, 360 lb. cross sectional dimensions as well as continuous groove welding to improve digging and side-contact strength. Sturdy Frame Structure The revolving frame, center frame and undercarriage are designed by using the most advanced three-dimensional CAD and FEM analysis technology. Reliable Components All of the major machine components, such as engine, hydraulic pumps, hydraulic motors and control valves, etc. , are exclusively designed and manufactured by Komatsu. [. . . ] Economy mode offers the user fuel savings, quiet operation and less CO2 emission. Production is the same as the PC350-6 Two Boom Settings 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 heavy duty mode. Economy Mode Economy mode is environmentally friendly. Fuel consumption is reduced 20% (compared with PC350-7 Active mode) 4 and production is equal to the PC350-6 heavy duty mode. Boom floats upward, reducing lifting of machine front. Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved. 5 PC350-7 H Y D R A U L I C E X C A V A T O R HYDRAULIC EXCAVATOR PC350-7 0 Safety Features Cab FOG capable with optional bolton top guard. WORKING ENVIRONMENT PC350-7 cab interior is spacious and provides a comfortable working environment. . . Wide Visibility Large Comfortable Cab Comfortable Cab New PC350-7's cab volume is increased by 14%, offering an exceptionally comfortable operating environment. The large cab enables full flat reclining of the seat back with headrest. The right side window pillar has been removed and the rear pillar reshaped to provide better visibility. Pump/engine room partition prevents oil from spraying on the engine if a hydraulic hose should burst. Thermal and fan guards are placed around high-temperature parts of the engine and fan drive. Steps with non-skid sheet Photo may include optional equipment. Pressurized Cab With 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. Low Noise Design Noise level is remarkably reduced, not only engine noise but also noise when swinging and hydraulic relief. and large handrail. Steps with non-skid sheet provide anti-slip footing for maintenance. Seat with headrest reclined full flat Photo may include optional equipment. Low Vibration with Cab Damper Mounting PC350-7 uses new, improved multi-layer viscous mount system that incorporates longer stroke and the addition of a spring. The new cab damper mounting combined with strengthened left and right side decks aids vibration reduction at operator seat. Vibration at floor is reduced from 120 dB (VL) to 115 dB (VL). dB (VL) is index for expressing size of vibration. Automatic Air Conditioner (optional) A 6, 900 kcal air conditioner is utilized. 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. Multi-Position Controls The multi-position, pressure proportional control levers allow the operator to work in comfort while maintaining precise control. A double-slide mechanism allows the seat and controllers to move together or independently, allowing the operator to position the controllers for maximum productivity and comfort.
