[. . . ] Output is 180 kW 242 HP, providing increased hydraulic power and improved fuel efficiency. Larger Digging Forces Provide Increased Production Bucket digging force and arm crowd force when Power Max is applied are increased 7% by improvement of hydraulic system. The larger digging forces generate the largest production in the 30 ton 33 U. S. *Bucket Digging Force: 228 kN 23200 kgf 51, 150 lb. *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. [. . . ] 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.
