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 SAA6D140E-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.
PRODUCTIVITY FEATURES

HD405-7 OFF-HIGHWAY TRUCK
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. K-ATOMiCS
(Komatsu Advanced Transmission with
Optimum Modulation Control System)
Automatic Retard Speed Control (ARSC)(Option)
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 HD405-7 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/mm2227,520 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.

High-rigidity frame
Cast-steel components are used in the
main frame for high-
stress areas where
loads and shocks are
most con-
centrated.
Komatsu components
Komatsu manufactures the engine, torque converter,
transmission, hydraulic units, and electrical parts on this
dump truck. Komatsu dump trucks are manufactured with an
integrated production system under a strict quality control
system.
Rigorous dump body design
The standard dump body is made of 160 kg/mm
2
227,520 PSI
high-tensile-strength steel for excellent rigidity and reduced
maintenance cost. The V-
shape design also
increases structural strength.
The side and bottom plates of
the dump section are rein-
forced with ribs for added
strength.
Reliable hydraulic system
The oil cooler is installed in the radiator lower tank, improv-
ing the reliability of the hydraulic system during sudden tem-
perature rises. Further, in addition to the main filter, a 25-
micron line filter is at the entrance to the transmission con-
trol valve. This system helps to prevent secondary faults.
Sealed DT connectors
Main harnesses and
controller connectors are
equipped with sealed DT
connectors providing high
reliability, water resistance
and dust resistance.
ABS (Antilock braking system) (Option)
Using its outstanding electronics technology, Komatsu is
the first in the industry to introduce ABS on construction
machinery. This system prevents the tires from locking,
thus minimizes skidding under slippery conditions while
applying the service brake.
ASR (Automatic spin regulator) (Option)
ASR automatically prevents the rear tires on either side
from slipping on soft ground for optimal traction.

Neutral safety
Even if the driver downshifts accidentally,a speed appropriate to the current gear is automatically set,preventing over-runs.
When descending grades, if the vehicle's speed surpasses the maximum for the current gear,
the rear brakes automatically operate, preventing over-runs.
The vehicle is prevented from moving backward when operating the body.
This device makes it impossible to shift from forward to reverse when the vehicle's speed surpasses 4 km/hour.
When running near a shift point, smooth automatic shifting takes place.
The engine is prevented from starting when the shift lever is not in neutral.
Flat face-to-face O-ring
seals are used to securely
seal all hydraulic hose
connections and to prevent
oil leakage.
Flat face-to-face O-ring seals
Advanced monitoring system
Extended oil change intervals
In order to minimize operating costs, oil change intervals
have been extended:
●Engine oil 500 hours
●Hydraulic oil 4000 hours
Centralized greasing
points (Option)
Greasing points are central-
ized at three locations.
Flange type rim
Flange type rims provide
easy removal/installation for
the tires.
Electric circuit breaker
A circuit breaker is adopted in
important electric circuits that
should be restored in a short
time when a problem occurs
in the electrical system.
Brake cooling oil recovery tank
To protect environment, a tank is installed to recover brake
cooling oil in the event of brake floating seal leakage.
Pedal-operated secondary brake
If there should be a failure in the foot brake, the parking
brake and front disc brakes
are activated as pedal operat-
ed secondary brake. In addi-
tion, when hydraulic pressure
drops below the rated level,
the parking brake is automati-
cally actuated.
Lead-free radiator
In addition to compliance with emission regulations, a lead-
free aluminum core is adopted for the radiator to comply
with global environmental requirements.
The Komatsu advanced monitoring system identifies main-
tenance items, reduces diagnostic times, indicates oil and
filter replacement hours and displays abnormality codes.
This monitor system helps to maximize machine production
time.
Wet multi-disc brakes and fully hydraulic braking
systems mean lower maintenance costs and higher relia-
bility. Wet disc brakes are fully sealed to keep contaminants
out, reducing wear and maintenance. Brakes require no
adjustments for wear, meaning even lower maintenance.
Added reliability is designed into the braking system by the
use of three independent hydraulic circuits providing
hydraulic backup should one of the circuits fail. Fully
hydraulic braking systems eliminate the air system so air
bleeding is not required, and water condensation that can
lead to contamination, corrosion and freezing is eliminated.

Grade distance: Continuous descent Grade distance: 450 m (1480 ft)
To determine travel performance: Read from
gross weight down to the percent of total
resistance. From this weight-resistance point,
read horizontally to the curve with the high-
est obtainable speed range, then down to
maximum speed. Usable rimpull depends
upon traction available and weight on drive
wheels.
To determine brake performance: These
curves are provided to establish the maxi-
mum speed and gearshift position for
safer descents on roads with a given dis-
tance. Read from gross weight down to
the percent of total resistance. From this
weight-resistance point, read horizontally
to the curve with the highest obtainable
speed range, then down to maximum
descent speed the brakes can safely han-
dle without exceeding cooling capacity.
