PRODUCTIVITY & ECONOMY
High performance Komatsu SAA12V140E-3
engine
Variable horsepower control (VHPC) with
mode selection system
This engine delivers faster acceleration and higher
travel speeds with high horsepower per ton. Advanced
technology, such as High Pressure Common Rail injection system (HPCR), air-to-air aftercooler efficient turbocharger gives high torque at low speed, impressive
acceleration, and low fuel consumption for maximum
productivity.
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. When the
key switch is turned on, Economy mode is selected
automatically. Select Power mode by using the switch
when needed.
VHPC (Variable horsepower control)
F7-R2 (RH/RL) fully automatic transmission
The transmission is configured with 7 forward and 2
reverse gears. Fully automatic control is applied to all
forward gears and an optimum gear is automatically
selected according to the
travel speed and engine
speed. The shifting point is
automatically selected depending on the acceleration
of the machine to reduce
excessive fuel consumption.
Both in Power and Economy modes, the VHPC system
detects whether machine condition is loaded or unloaded and selects optimum horsepower setting mode, providing both high production and low fuel consumption.
Power mode: Makes best use of the horsepower to attain optimal production. This mode is suitable for operation in job sites including uphill travel with load where
powerful hauling is top priority.
Economy mode: Sets the maximum horsepower at low
level to reduce fuel consumption. The machine maintains sufficient power for economical operation in this
mode.
Two-speed selective reverse gears (RH/RL)
In order to meet various operating conditions, two
reverse gears are provided. The switch on the panel
allows the operator to select optimum reverse gear of
RH or RL depending on the job site conditions. Furthermore, the reverse gear is equipped with a lockup clutch,
allowing the operator to reverse the machine without
overheating.

Anti-pitching 4-wheel oil-cooled multiple disc
retarder
The machine is equipped with an anti-pitching 4-wheel
oil-cooled multiple disc retarder that applies retarding
force on all four wheels. With this retarder, the retarding force is shared between four wheels. This reduces
the possibility of tire-lock and enables effective use of
retarder capacity, allowing stable downhill travel. The
machine descends slopes smoothly and comfortably
without machine pitching since retarding force on front
and rear wheels is controlled independently.
HD785-7
Auto 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 per click
to match the optimum speed for the slope. Also, when it
is predicted that the retarder oil temperature becomes
overheated, since the retarder oil temperature is always
monitored, operator is informed this by warning lamp.

PRODUCTIVITY & ECONOMY
Eliminating hydraulic losses & optimizing
transmission control
Hydraulic circuits such as brake cooling, steering, body
dump control, transmission control etc. are optimized
to reduce fuel consumption. As a result, the fuel consumption for operation with medium and light load is
improved.
Automatic Idling Setting System (AISS)
This system facilitates quick engine warmup and cab cooling/warming. When setting
the system ON, engine idle speed is kept at
945 rpm when coolant temperature is 50 °C
or lower. Speed automatically returns to 750 rpm when
coolant temperature reaches 50 °C.
Small turning radius
A-frame
The MacPherson strut type
front suspension has a special
10,1 m
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.

Long wheelbase and wide tread
With an extra-long wheelbase, a wide tread and an
exceptionally low center of gravity, the HD785-7 hauls
the load at higher speed for greater productivity, and
delivers superior driving comfort over rough terrain.
Large body
A wide target area makes for easy loading with minimal
soil spillage and more efficient hauling.
