PRODUCTIVITY FEATURES
Komatsu’s new “ecot3” engines are designed
to deliver optimum performance under the
toughest of conditions, while meeting the
latest environmental regulations. This engine
is EPA Tier 3, EU Stage 3A and Japan emissions certified. “ecot3” – ecology and
economy combined with Komatsu technology
to create a high performance engine without
sacrificing power or productivity.
Environment-Friendly Clean Engine
The PC1250LC-8, which is equipped with the
Komatsu SAA6D170E-5 engine, is USA EPA
Tier 3 and EU stage 3A emission certified.
The SAA6D170E-5 engine adopts the world’s
first cooled EGR system with electronically
controlled bypass-assist type venturi. NOx
emissions are reduced by 40%, while maintaining high power and low fuel consumption.
Electronically Controlled Variable
Speed Fan Contributes to Low
Fuel Consumption and Low Noise
The electronic control system sets the
rotational speed of the cooling fan
according to coolant, hydraulic oil,
and ambient temperatures. It effectively uses engine output to prevent
wasteful fuel consumption and
reduces noise during low-speed fan
rotation.
Reduction of Ambient Noise
The above image is a 3D illustration and may differ
from actual engine.
Fuel Consumption Reduced
Using Economy Mode
Enables operator to set
Economy mode to any of four
levels according to working conditions. Production requirement
is achieved at lowest possible
fuel consumption.

In addition to the electronically-controlled variable-speed
fan drive, noise levels are further reduced with a low-noise
muffler with cover, hybrid fan, low-noise components, and
sound absorbing padding installed throughout the machine.

Swing Priority Setting
Shockless Boom Control
The PC1250LC-8 features a shockless boom control (double-check slow return valve) which automatically reduces
the amount of vibration present when operating the boom.
Operator fatigue is reduced (which can improve safety and
productivity) and spillage caused by vibration is minimized.
The swing priority setting allows the operator to use the
same easy motion for 180˚ loading as 90˚ loading
operations. By proportioning the oil flow, this setting allows
the operator to select either boom or swing as the priority
for increased production.

RELIABILITY FEATURES
Excellent Reliability and Durability
Boom Foot Hoses
High-Pressure In-line Filtration
Sturdy Undercarriage
The boom foot hoses are arranged
under the boom foot to reduce hose
bend during operation, extending hose
life and improving operator safety.
The PC1250LC-8 has the most
extensive filtration system available,
providing in-line filters as standard
equipment. An in-line high pressure
filter in the outlet port of each main
hydraulic pump reduces failures
caused by contamination.
The undercarriage is strengthened to
provide excellent reliability and
durability when working on rocky
ground or blasted rock.
Strengthened Boom and Arm
With large cross-sectional structures,
thick high tensile strength steel
plates, and partition walls, the boom
and arm structures exhibit excellent
durability and are highly resistant to
bending and torsional stress.
