Komatsu technology

Komatsu develops and produces all major components,

such as engines, electronics and hydraulic components, 

in house.

With this “Komatsu Technology,” and adding customer 

feedback, Komatsu is achieving greater advancements 

in technology.

To achieve both high levels of productivity and economical

performance, Komatsu has developed the main compo-

nents with a total control system.

The result is a new generation of high performance and

environment friendly machines.

High performance Komatsu SAA6D170E-5 engine

This engine delivers faster acceleration and higher

travel speeds with high horsepower per ton. Advanced

technology, such as Common Rail Injection system (CRI),

air to air aftercooler, efficient turbo-charger, and heavy duty

cooled EGR enables the engine to be North American EPA

Tier 3 and EU stage 3A emission certified. High torque at

low speed, impressive acceleration, and low fuel consump-

tion ensure maximum productivity.

Mode selection system

The system allows selection of the appropriate mode

between two modes  <Power mode > or <Economy mode>

according to each working condition. The mode is easily

selected with a switch in the operator’s cab.

Power mode

Great productivity can be attained by taking full advantage

of high output power. It is appropriate for job sites where

larger production uphill-hauling is required.

Economy mode (Variable horsepower)

The engine power automatically changes depending on

loaded or unloaded conditions always to use an optimum

speed gear. It is appropriate for light work on flat ground.

7-speed, fully automatic K-ATOMiCS transmission

The K-ATOMiCS (Komatsu Advanced Transmission with

Optimum Modulation Control

System) automatically selects

the optimum gear according

to vehicle speed, engine

speed and the shift position

you’ve chosen. The result:

the best gear for any driving

situation.

(Komatsu Advanced Transmission with

Optimum Modulation Control System) 

Automatic Retard Speed Control (ARSC)

ARSC allows the operator to simply set the downhill travel

speed and go down slopes at a constant speed. As a

result, the operator can concentrate on steering. The speed

can be set at increments of 1 km/h 0.6 MPH per click (±5

km/h 3.1 MPH of maximum speed adjustment) to match

the optimum speed for the slope. Also, since the retarder 

cooling oil temperature is always monitored, the speed is

automatically lowered.

Fully hydraulic controlled wet multiple-disc
brakes and retarder

Wet multiple-disc brakes ensure highly reliable and stable

brake performance. The large-capacity, continuously

cooled, wet-multiple disc brakes also function as a highly 

responsive retarder which gives the operator greater 

confidence at higher

speeds when travel-

ling downhill.

Long wheelbase and wide tread

With an extra-long wheelbase, a wide tread and an excep-

tionally low center of gravity, the HD605-7 hauls the load at

higher speed for more production, and delivers superior driv-

ing comfort over rough terrain.

Large high strength body

A wide target area makes for easy loading with minimal soil

spillage and more efficient hauling. The body is built of

160 kg/mm

2

227,520 PSI wear-resistant high-tensile steel

with a Brinell hardness of 500. 

The V-shape design also increases structural strength, and

provides excellent load stability.

Small turning radius

The MacPherson strut type front suspension has a special

A-frame between each wheel

and the main frame. The

wider space created

between the front wheels

and the main frame

increases the turning

angle of the wheels. The

larger this turning angle,

the smaller the turning

radius of the truck.

Automatic Idling Setting System (AISS)

This system facilitates quick engine warm-up and cab cool-

ing/warming. When setting the system ON, engine idle

speed is kept at 945 rpm when coolant temper-

ature is 50°C 122°F or lower. Speed automati-

cally returns to 750 rpm when coolant tempera-

ture reaches 50°C 122°F.
