Engine
The PC270-7 gets its exceptional power and work capacity from a Komatsu SAA6D102E-2 engine. Output is 134 kW 179 HP, providing increased hydraulic power and improved fuel efficiency.
Hydraulics
Unique two-pump system ensures smooth compound movement of the work equipment. [. . . ] 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 (6. 0 mm Aq 0. 2" 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
PC270-7 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.

MAINTENANCE FEATURES
Easy Maintenance
Komatsu designed the PC270-7 to have easy service access. We know by doing this, routine maintenance and servicing are less likely to be skipped, which can mean a reduction in costly downtime later on. Here are some of the many service features found on the PC270-7. Easy Radiator Cleaning Clearance between radiator and oil cooler is increased to facilitate radiator core cleaning with an air nozzle.
