OPERATOR ENVIRONMENT
Powerful KOMATSU SAA6D125E-3 Engine
This engine delivers quicker acceleration and higher travel
speed with the highest output per weight. Advanced technology, such as Common-Rail fuel Injection system, air-to-air
aftercooler, and an efficient turbocharger
enables the engine to
meet the North American
EPATier 2 emission regulations. High torque at
low speed, impressive
acceleration, and low fuel
consumption ensures
maximum productivity.
6-Speed, Fully Automatic K-ATOMiCS
Transmission with Shift-Limiter Function
The K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System) automatically selects optimum gear according to vehicle speed, engine speed and
shift position you’ve chosen. Ashift-limiter function is
equipped as a standard. It enables to maintain 1st gear
when the vehicle desends a steep grade.
Oil-Cooled Multiple-Disc Retarder and Exhaust
Brake
The large capacity continuously oil-cooled wet multiple
disc retarder and the exhaust
brake are equipped as standard and enable safe and
continuous faster downhill
drive.
High Strength Quarry
Body for Easy Loading Operation
The robust body is constructed of thick wear-resistant steel
having 500 Brinell hardness. The V-shape, flat-bottom design
also increases structural strength, and provides excellent
load stability.
Outstandingly Small Turning Radius
The A-frames employed to
the front wheels give a
large steering angle, and
realizes the outstandingly
small turning radius. It
enables to position the
truck at a desired place
easily and quickly.
Wide, Specious Cab with Excellent Visibility
The cab is integrated with ROPS and the structures conform
to ISO 3471 and SAE J1040 standards. The driver’s compartment makes it very easy and
comfortable for the operator to
use all the controls. The wide
windshield and large rearview
mirrors provide the superior visibility and safety operation.
Suspension Seat
The suspension, fabric-covered seat which is adjustable to
the operator’s weight is provided as standard. The suspension seat dampens vibrations transmitted from the machine
and reduces operator fatigue as well as holding the operator
securely to assure confident operation.
Automatic Supplementary Steering and Secondary
Brakes
Automatic supplementary steering and secondary brakes are
employed as a standard.
If an abnormality occurs in the steering hydraulic circuits or
engine stops suddenly, this supplementary steering system
works automatically and enables to continue steering operation.
Steering: ISO 5010, SAE J1511, SAE J53
Brakes: ISO 3450, SAE J1473
Hydropneumatic Suspension for All Terrains
The hydropneumatic
suspension assures
comfortable ride even
over rough terrain and
ensures maximum productivity and operator
confidence.
