Heavy-duty Rock Bucket (optional)
Packaged wear-resistant reinforcement plates are available. The repair cost of the bucket can be considerably reduced with
the new design.
Reduced Inspection/maintenance
and Overhaul Man-hours
Achieves Total Cost Reduction
Power module packaging for easy
installation and removal of
components
Engine, radiator, oil cooler, hydraulic
pumps and PTO are packaged within
the Power module. This design
facilitates installation and removal of
components, contributing to the
reduction of maintenance
transportation and overhaul hours.
Simple construction and enlarged
components reduce the number of
parts
Use of a single-engine, enlarged
hydraulic pumps and simplified
hydraulic circuit enables reduced
hours required for checking and
maintenance. Moreover, significant
reduction of number of parts
contributes to reduction of overhaul
man-hours, resulting in total cost
reduction.

High cooling efficiency machine
design
Increased oil cooler capacity lowers
the heat balance temperature of
hydraulic oil to realize a cooler
operating machine. Heat-resistant
rubber seals are used in hydraulic
pumps and cylinders to significantly
increase component durability. These
improvements dramatically extend
the service life of the hydraulic
system.
* KVX materials :
Komatsu developed, wear-resistant, reinforced
materials. Brinell hardness: 500 or more
(180kgf/mm
2
class). Features high wear-
resistance and less heat-induced alteration
during rock digging, maintaining long term
hardness.

Arm Rock Protector Guards the
Arm Against Impact
Arm rock protector is equipped as
standard. The protector guards the arm
greasing piping against impact.
Strengthened Frame Structure
Revolving frame, center frame and
crawler frame are strengthened
completely. The frames endure heavy-
duty work and exhibit excellent
durability.
Durable Swing Circle with
Triple-roller Bearing
Large capacity triple-roller bearing is
used for the swing circle. The swing
circle endures
heavy-duty
excavating and
loading work, and
exhibits excellent
durability.

Compared with current model
Sturdy Guard and Large Track
Link
Travel motors are shielded by sturdy
guards. They prevent the motors from
being damaged by the thrust of rocks.
Enlarged track rollers, in combination
with the largest size track links, provide
excellent
durability.
Wear-resistant Float Pin
Boom top pin and arm top pin are
floating type. Since the pin can freely
rotate, it receives less friction load and
exhibits excellent reliability and
durability.
