MAJOR COMPONENTS AND SPECIFICATIONS
ENGINE
The KOMATSU 530M Haulpak Truck is powered by a
Cummins diesel engine.
TRANSMISSION
The TORQFLOW transmission consists of a 3-element,
single-stage, two-phase torque converter and a plane-
tary gear, multiple disc clutch transmission which is
hydraulically actuated and force-lubricated for opti-
mum heat dissipation.
The TORQFLOW transmission is capable of seven (7)
forward speeds and one (1) reverse gear. Automatic
shifting is controlled by electronic shift control with
automatic clutch modulation in all gears. A lockup
system consisting of a wet, double-disc clutch, is acti-
vated in F1--F7 gears for increased fuel savings.
FINAL DRIVE ASSEMBLY
The final drive consists of a plug-in differential with
planetary wheel drive.
OPERATOR'S CAB
The 530M Operator's Cab has been engineered for
operator comfort and to allow for efficient and safe
operation of the truck.
The cab provides for wide visibility, with an integral
4-post ROPS/FOPS stucture, and an advanced analog
operator envirnment. It includes a tinted safety-glass
windshield and power-operated side windows, a de-
luxe interior with a fully adjustable seat with lumbar
support, a fully adjustable/tilt steering wheel, controls
mounted within easy reach of the operator, and an
electronic display/monitoring panel to keep the opera-
tor informed of the truck's operating circuits. Audible
alarms and indicator lights warn the operator of system
malfunctions.
POWER STEERING
The 530M Haulpak Truck is equipped with a full time
power steering system which provides positive steer-
ing control with a minimum of effort by the operator.
The system includes nitrogen-charged accumulators
which automatically provide emergency power if the
steering hydraulic pressure is reduced below an estab-
lished minimum.
BRAKE SYSTEM
Depressing the brake pedal, or pulling the lever on the
R.H. side of the steering wheel, actuates hydraulic front
and rear service brakes. Both front and rear service
brakes are oil-cooled, multiple-disc brakes. These
brakes are automatically activated when the engine
speed exceeds the rated revolutions of the shift posi-
tion.
RETARDER
The operator can manually apply both the front and
rear oil-cooled, multiple-disc brakes by moving the
retarder contol lever which is mounted on the steering
column, or by using the foot-operated brake pedal.
SUSPENSION
Hydro-pneumatic suspension cylinders are used at
each wheel to reduce shock and provide riding comfort
for the operator and machine stability.
