Automatic Transmission with
Electronically Controlled Modulation Valve (ECMV)
Automatic transmission with ECMV automatically selects the
proper gear speed based on travel speed, engine speed, and
other travel conditions. The ECMV system engages the
clutch smoothly to prevent lags and shocks when shifting.
This system provides efficient machine operation and a
comfortable ride.
●
Kick-down switch:
This valuable feature for
increases productivity.
With the touch of a finger,
the kick-down switch
automatically downshifts
from second to first when
beginning the digging cycle. It automatically upshifts from
first to second when the direction control lever is placed in
reverse. This results in increased rim pull for better bucket
penetration and reduced cycle times for higher productivity.
●
Hold switch:
Auto shift is selected and if the operator
turns on this switch when the lever is at the 3rd gear
speed position, the
transmission is fixed to that
gear speed.
Electronically Controlled Transmission Lever
Easy shifting and directional changes with Komatsu two-lever
electronic shifting. Change direction or shift gears without
removing the shifting hand from the steering wheel. Solid
state electronics and conveniently located direction and gear
shift controls make this possible. Automatic shifts in ranges
two through four keep production
high and manual shifting at a
minimum.
AJSS (Advanced Joystick Steering System)
(Optional)
AJSS is a feedback steering system which has been
incorporated to allow steering and forward and reverse
selection to be controlled
by wrist and finger control.
With the feedback
function, the machine
steering angle is exactly
the same angle as the
lever tilt angle.
Tiltable Steering Column & One-Glance Monitors
The steering column can be
easily tilt-adjusted to the most
comfortable position with one
lever.

Variable Transmission Cut-off System
The operator can set the transmission cut-off pressure
desired for the left brake pedal using the switch located on
the right-side control panel. The operator can improve the
working performance by setting the cut-off pressure properly
depending on working condition.
●
High cut-off pressure for digging operations.
●
Low cut-off pressure for truck-loading operations.
Remote Boom Positioner
The highest and lowest position of the bucket can be set
from the cab to match any
truck body. Once the positioner
is set, the bucket is smoothly
stopped at desired position
with no shock.
Roomy, Quiet Cab With Power Windows
The cab is large, with a comfortably spacious interior and
power windows. Also, a wide viewing angle is guaranteed
because the cab is pillar-less. By
adopting a high-capacity air
conditioner, Komatsu ensures
operator comfort, no matter the
exterior conditions. Other features
designed with operators in mind
include a lunchbox storage space.
Low Vibration & Noise
The cab rests on Komatsu viscous damping
mounts (rubber and silicon oil) to reduce
vibration and noise. All hydraulic
equipment is mounted on high-resistance
rubber to further reduce vibration and noise.
Pillar-less Large Cab with ROPS / FOPS Canopy
A wide pillar-less flat glass provides excellent front visibility.
The wiper arm covers a
large area to provide great
visibility even on rainy
days.
Comfortable Operator's Seat
The operator's seat has a
reclining/air suspension design with
headrest to support the operator
comfortably during long operation.
Also, it is easy to adjust seat height
with air suspension.
