PRODUCTIVITYFEATURES
PRODUCTIVITYFEATURES
High Production and Low Fuel ConsumptionEngine
The PC270LC-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. HydrauMind controls both
pumps for efficient engine power use. This system also
reduces hydraulic loss during operation.
Large Digging Height
PC270LC-7’s maximum digging height is 10.13 m 33'3",
facilitating jobs that require a longer reach, such as
demolition and slope finishing.
Larger Forces Provides Increased Production
Four Working ModesWorking Mode Selection
The PC270LC-7 excavator is equipped with four working
modes (A, E, L and B mode). Each mode is designed to match
engine speed, pump speed, and system pressure with the
current application. This provides the flexibility to match
equipment performance to the job at hand.
Economy Mode
Economy mode is environmentally friendly. Fuel consumption is
reduced 16% (compared with PC270LC-7 Active mode) and
production is equal to the PC270LC-6 Heavy-duty mode.
Power Max Function
This function temporarily increases digging force by 7% for
added power in tough situations.
Lifting Mode
When the Lifting mode is selected, lifting capacity is increasedby 7% by raising hydraulic pressure.
Bucket Digging Force*: SAE 175 kN 17900 kg 39,460 lbISO 198 kN 20200 kg 44,530 lb
Arm Crowd Force*: SAE 136 kN 13900 kg 30,640 lbISO 148 kN 15100 kg 33,290 lb
*Measured with Power Max function, 3045 mm 10'0" arm
Working Mode Application Advantage
Active mode● Maximum production/power
A● Fast cycle times
E Economy mode ● Excellent fuel economy
L Lifting mode ● Hydraulic pressure isincreased by 7%
B Breaker ● Optimum engine rpm,operation hydraulic flow
Automatic Three-Travel Speed
Travel speed is automatically shifted from high to low speedaccording to the pressure of the travel.

Travel Speed5.5 km/h 4.1 km/h 3.0 km/h3.4 mph 2.5 mph 1.9 mph
Larger Maximum Drawbar Pull
PC270LC-7’s maximum drawbar pull is
increased by 9%, provides superb
steering and slope climbing performance.
Maximum drawbar pull: 249 kN 25400 kg 56,000 lb
Drawbar pull/operating weight: 0.89

Multi-Function Color MonitorA newly developed Multi-Function Color Monitor has multiplefunctions, such as Working mode selection, hydraulic pumpoil flow adjustment for matching to attachment, andmaintenance interval notice, etc.
Working Mode Selection
The Multi-Function Color Monitor allows for easy selection ofthe working modes (A, E, L and B modes).
EMMS (Equipment Management Monitoring System)
Monitor FunctionController monitors engine oil level, coolant temperature, batterycharge and air clogging, etc. If the controller finds anyabnormality, it is displayed.
Maintenance FunctionThe monitor informs replacement time of oil, filters and othermaintenance items when the designated interval is reached.
Trouble Data Memory FunctionThe monitor stores machine abnormalities for effectivetroubleshooting.
Excellent Reliability andDurability
● High Rigidity Work Equipment
The arm and boom are strengthened
to correspond to increasing bucket and arm
digging forces. The arm and boom cross sectional
strength are also increased 25% and 8% respectively.
The boom and arm have large cross-sectional dimensions as
well as continuous groove welding, improving 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.
● Highly Reliable Electronic Devices
Exclusively designed electronic devices have passed severe testing.
● Controller ● Sensors
● Connectors ● Heat resistant wiring

WORKINGENVIRONMENT
WORKINGENVIRONMENTPC270LC-7 cab interior is spacious and provides a comfortable workingenvironment…
Large Comfortable CabComfortable Cab
New PC270LC-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.
Pressurized Cab
The 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.
Low Vibration with Cab Damper Mounting
PC270LC-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.
