Equipped with an eco-friendly engine
Equipped with the SAA6D125E-5 engine, this new mobile
crusher has a nominal output as high as 262.5 kW (352 HP).
The latest KOMATSU engine technology for construction
machinery, "ecot3", greatly reduces NOx emissions. This eco-
friendly, clean engine, complies with various emission gas
standards, including the EPA Tier 3 requirements in North
America and the EU Stage 3A requirements in Europe.
New Komatsu Jaw Crusher
The large-capacity jaw crusher, KCJ4430, is another
successful example of Komatsu's development efforts.
Crushing efficiency is improved dramatically with the
installation of a load-presetting semiautomatic feeder system.

High-speed, large-capacity conveyor belt
The high discharge height of 3000 mm (9'10") makes it easy
to configure a system with stock pile conveyor and screens.
With its width of 1050 mm (42") and a belt speed of 120 m
(394') /min., the belt conveyor has a high volume capacity. In
addition, the conveyor reverse mode is provided to facilitate
the removal of jammed foreign material.

Komatsu's hydraulic crusher protection
mechanism
Jaw crushers typically protect themselves by bending toggle
plates when they are clogged or
jammed with metal or wood debris. The
KCJ4430 protects itself by allowing the
locking cylinders to fully open the
discharge port, which makes it easy to
remove clogged foreign material from
the crusher. (Patent pending)
Fully automatic discharge setting adjustment
system
The jaw crusher is equipped with an automatic discharge
setting adjustment system that makes it easy to change the
opening of the discharge port. Even as both of the jaw plates
or one wear, you can adjust the discharge setting with a
simple one-touch operation (adjustable within several minutes)
with this automatic system. On the monitor panel, you can
choose one of the three adjustment modes. (Patent pending)
Mode A: Input a desired value
for the discharge
setting.
Mode B: Increase or decrease
the current discharge
setting.
Mode C: Press the manual
switch to increase or
decrease the present
discharge setting.
Large production capacity
Komatsu's original large-capacity jaw crusher and the most
advanced control systems have considerably increased its
output capacity, making it easy to manage large workloads.
High mobility
The conveyor elevation system secures sufficient ground
clearance, which provides the crusher with outstanding
maneuverability at any crushing site. In addition, improved
configuration and location of the guide handle makes it much
easier to operate the conveyor lifter.
The mobile crusher uses a new interlock system that controls
the travel and the operation (crushing), depending on the
conveyor's position.
The system helps prevent the conveyor from being dragged
or contacting the ground and provides clearance between the
jaw discharge and the conveyor belt.

Ease of operation
All the switches necessary for operation are located on the
main control panel, making it easier for the operator
standing on the ground to reach and control the operation.
As the control system is equipped with the one-touch start
feature, all you have to do is to push the start switch. This
simple operation will sequentially start the operation of the
magnetic separator, belt conveyor, jaw crusher and feeder.
Main Control Panel
The multi-function monitor displays the status of all
components in real time. With this monitor, you can easily
identify the location of a problem.

Wired remote controller for travel
Wired remote controller allows travel control while standing
on the ground.
The controller facilitates travel control by
eliminating the need to get on the machine.
Since the connector for the remote
controller is provided both on the front and
rear of the machine, you can select either
one according to your needs. In addition,
conventional on-board travel control lever
system is optionally available.
Radio remote controller (Option)
With this controller, you can change the
mode between "Travel" and "Operation",
while remaining onboard. You can also use
it to operate the one-touch start feature, in
addition to the feeder On/Off function.

Maximum reliability and minimal maintenance
In addition to the spacious large clearance between the jaw
crusher and the conveyor belt, the crusher's bottom area is
sealed with covers. This design prevents re-bar from being
caught by the crusher's member
structure. Wide openings on the
side frames also ensure easy
access to the space below the
