OM5005 04/98 Specifications - Section 5 Page 5-1 MAJOR COMPONENTS AND SPECIFICATIONS ENGINE POWER STEERING The KOMATSU 530M Haulpak Truck is powered by a Cummins diesel engine. 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.
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. 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 FINAL DRIVE ASSEMBLY 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. The final drive consists of a plug-in differential with planetary wheel drive.
OPERATOR’S CAB SUSPENSION The 530M Operator’s Cab has been engineered for operator comfort and to allow for efficient and safe operation of the truck. Hydro-pneumatic suspension cylinders are used at each wheel to reduce shock and provide riding comfort for the operator and machine stability. 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.
