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.

High Mid Low

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.
