High Productivity and Low Fuel Consumption
Powerful Engine
The electronically controlled fuel injection timing in the
SAA6D125E-3 engine provides optimum combustion of fuel
at both low and high speed/power applications.This system
also provides fast throttle response to match the machine’s
powerful rim pull and fast hydraulic response.
195 kW, 261 HP
The common rail type fuel injection system provides
maximum power with minimum emissions.This engine
meets EPA Tier II emission regulations and EC second
emission regulations.
Low Fuel Consumption
The fuel consumption is reduced greatly because of the
low-noise, high-torque engine and the large-capacity torque
converter with maximum efficiency in the low-speed range.
Reduction of Fuel Consumption: 15% (compared with
Dash 3 technology).
Dual-Mode Select System
This wheel loader offers two selectable operating modes—
Normal and Power. The operator can adjust the machine’s
performance by flipping a switch.
● Normal Mode: This mode
provides maximum fuel
efficiency for most of
general loading.
● Power Mode: This mode
provides maximum power
output for hard digging
operation or hill climb.
Transmission Mode Select System
This operator controlled system allows the operator to
select manual shifting or three levels of automatic shifting
(low, medium, and high).
shifting is performed at relatively low engine speeds,
suitable for general excavating and loading.
● Auto. M: Gear is shifted at medium engine speeds
between those of L and H modes.
● Auto. H: This mode provides large rim pull and shor t
cycle time since gear shifting is performed at relatively
high engine speeds, suitable for load and carry operation
on uphill.
New Dual-Speed Hydraulic System
Komatsu’s dual-speed hydraulic system increases
operational efficiency by matching the hydraulic demands
to work conditions.
Oil from the switch pump is completely returned to the tank
when digging and breaking out, therefore, hydraulic flow
to the loader is reduced and pressure is increased.This
reduces horsepower demand from the engine and makes
the operation more efficient. Kick-down switch signal also
controls the oil flow. This new technology is greater
productivity at the lowest operating cost.
● Manual: Transmission is
fixed to gear speed selected
with gear shift lever.
● Auto. L: This mode
provides smooth gear
change and low fuel
consumption since gear
Maximum Dumping Clearance and Reach
The long lift arms provide
high dumping clearances
and maximum dumping
reach.The operator can
even level loads on the
body of a dump truck
easily and efficiently.
Long Wheelbase/Articulation Angle of 40˚
The longest wheelbase in class and the widest tread provide
improved machine stability in both longitudinal and lateral
directions. Since the articulation angle is 40
can work efficiently even in the tightest job sites.
